Free Gibbs energy (ΔG°) of the sorption processes as well as the equilibrium parameter (RL) have been calculated for each pollutant-sorbent couple. The study revealed that: i) for cadmium sorption, IW2 was much more effective than IW1 and especially than AC (18-fold higher in term of maximal sorption capacity); ii) if IW2 was slightly less effective than AC to retain lead, it can be still considered as an interesting sorbent due to its low cost; iii) the sorption of cadmium was as spontaneous on AC as on IW1, and almost half as much on IW2; iv) regarding lead retention, the sorption on the three sorbents was spontaneous; (v) the retention of cadmium and lead was mainly explained by precipitation since otavite, cerussite and hydrocerussite were identified and characterized by X-ray diffraction of used sorbents. The study showed that the industrial wastes studied stood out as new efficient materials with sorption power equal to or greater than the reference material AC. The prospect of a new generation of industrial wastes with lasting efficiency as contaminated water depollution agents comes at a key moment in the search for new perspectives in the circular economy. |

in agroecosystems but little is known about the timing and the origin

was to measure the change in soil biodiversity abundance and repartition
during the first year of tree plantation at an experimental agroforestry
(AF) site in northern France. The experimental site is located in
Ramecourt (50° 22' N, 2° 17' E) on an 18-ha plot according to a randomized
bloc design with 3 replicates. Modalities with or without nitrogen-fixing
trees in AF treatment are compared with sole-crop (CC) and pure-forest
control (FC) plots. In November 2018, one-year-old trees and shrubs
were planted in 38 meters and 7 meters wide rows for AF and FC respectively.
Within rows, 6 species of tall trees (Quercus robur, Carpinus betulus,
Juglans regia x regia, Alnus glutinosa, Prunus avium, Robinia pseudoaccacia)
were planted 8 meters apart and were intercalated every 1 meter by
9 species of shrubs (Castanea sativa, Cornus sanguinea, Acer campestris,
Euonymus europaeus, Corylus avelana, Tilia cordata, Ligustrum vulgaris,
Salix alba, Viburnum lantana). The density of tall trees is 50 and
430 trees ha-1 for AF and FC respectively. In AF, a spring barley
was sown in February 2019 in the alley after a shallow stubble ploughing
as well as in CC plots. In FC, cover plants composed of a mixture
of melliferous and grass plant species were sown between tree rows
in April 2019. The population of earthworms, micro and macroarthropods
were measured from April to July 2019 using mustard extraction method,
Berlese and Barber traps respectively. The collected organisms were
counted, classified and identified thanks to a determination key
based on morphological criteria. The abundance and the dominancy
of each recognized families, genus or species were calculated as
well as the Shannon-index for the diversity. A total number of 833
earthworms was collected in all plots. Anecic species were dominant
(i.e. between 50% and 75% of the total number) whereas endogenic
and epigeic species were common (i.e. between 25% and 50%) and very
rare (< 5%) respectively. The abundance of earthworms was not significantly
different between AF (25.3 ind. m-2), CC (28.6 ind. m-2) and TF (19
ind. m-2). The relative abundance of the same ecological category
of worms was roughly the same for the three treatments. A total number
of 85 microarthropods was counted. Mites and collembola represented
in average 26% and 32% of the population respectively. The remaining
individuals were composed of myriapods, enchytreids and insects.
The calculated Shannon-index for the microarthropods was significantly
higher in AF (1.03) and FC (1.19) than in CC (0.26). While 7 families
of microarthropods were recorded in both AF and FC, only 3 families
were noted in CC, suggesting that at this early stage of trees development,
the population of microarthropods could benefit from more diverse
habitat and food provided by tree lines. For macroarthropods, a total
number of 11,005 individuals were collected during the 4 weeks of
sampling. Some zoological groups such as Staphylinidae, Ephistemus,
Bembidion and Araneae were only observed in AF. The abundance of
macroarthropods decreased from the beginning to the end of sampling
period in CC and FC whereas it remained stable in AF. This decrease
was probably due to the hot and dry weather conditions in July 2019.
It can be assumed that in AF, the microclimate and habitats, which
were created together by tree rows and crop canopy cover, promoted
the resilience of the installed ecosystem, allowing the maintenance
of food chain predators. The drying up of cover plants in FC or the
absence of tree rows in CC was not favourable to maintain macroarthropods
populations over time. Our study showed that the micro and macro
arthropods’ community abundance and repartition in soil react very
quickly within one year after tree plantation in AF, thanks to the
creation of favourable habitats for their development along the tree
rows. Further work is necessary to confirm these tendencies in the
following years and to identify their consequence in the ecosystem
functionning.},

abstract = {A new environmentally friendly approach for the synthesis of idrocilamide
(1), a marketed myorelaxant and anti-inflammatory agent, is reported
herein. The synthetic strategy involves a solvent-free aminolysis
reaction catalyzed by zinc-containing species (ZnCl2, montmorillonite
K10 (MK10) impregnated with ZnCl2 or eco-catalysts). The latter have
been prepared from the aerial parts of Lolium perenne L. plants grown
on contaminated soils from northern France without and with thermal
activation at 120 °C and supported on MK10 (Ecocat1 and Ecocat2,
respectively). The best aminolysis catalysts in the current study
(ZnCl2 and Ecocat2) were selected for additional aminolyses. Compared
to ZnCl2, Ecocat2 had the advantage of being reusable over five test
runs and constituted a sustainable catalyst allowing a green route
to idrocilamide. Synthesized derivatives 1–4, 6 and 9 were first
evaluated for their effect on reactive oxygen species (ROS) generation
from macrophages and displayed antioxidant properties by preventing
ROS production. Next, the analysis of the effect of molecules 1–4,
6 and 9 on macrophage migration between epithelial cells to human

A new environmentally friendly approach for the synthesis of idrocilamide
(1), a marketed myorelaxant and anti-inflammatory agent, is reported
herein. The synthetic strategy involves a solvent-free aminolysis
reaction catalyzed by zinc-containing species (ZnCl2, montmorillonite
K10 (MK10) impregnated with ZnCl2 or eco-catalysts). The latter have
been prepared from the aerial parts of Lolium perenne L. plants grown
on contaminated soils from northern France without and with thermal
activation at 120 °C and supported on MK10 (Ecocat1 and Ecocat2,
respectively). The best aminolysis catalysts in the current study
(ZnCl2 and Ecocat2) were selected for additional aminolyses. Compared
to ZnCl2, Ecocat2 had the advantage of being reusable over five test
runs and constituted a sustainable catalyst allowing a green route
to idrocilamide. Synthesized derivatives 1–4, 6 and 9 were first
evaluated for their effect on reactive oxygen species (ROS) generation
from macrophages and displayed antioxidant properties by preventing
ROS production. Next, the analysis of the effect of molecules 1–4,
6 and 9 on macrophage migration between epithelial cells to human
opportunistic fungus Candida albicans indicated that molecules 2–4,
6 and 9 exert anti-inflammatory properties via reducing macrophage
migration while the parent idrocilamide (1) did not show any significant
effect. This work opens the way for the discovery of new analogues
of idrocilamide with improved properties. |

between renewed interest and vigilance - With the increasing artificialisation
of urban and peri-urban soils, the demand for nature in cities is
regaining real vigour. This is almost unexpected for vegetable gardens.
Indeed, three to four decades ago the cultivation of vegetable gardens
at home or in collective gardens was obsolete, in particular due
to access to fruit and vegetables facilitated by intensive agriculture.
Today, if the economic interest of the vegetable garden continues,
the reasons for this revival are more in the social bond, the practice
of a physical activity or the will to eat healthy. However, the dynamics
of this form of urban agriculture and in particular vegetable gardens
can be translated into hasty projects for which certain elements
of "common sense" would be neglected. Thus, the extension of the
city over the city leads to changes in land use that can, for example,
increase the exposure of populations to pollutants. The compatibility
between the state of the environment and the uses must then be checked;
this exercise is not always easy given the diversity of the situations
encountered. (2) A range of projects and actors: from disciplinary
case studies to multidisciplinary projects - An inventory is proposed,
carried out on the one hand, on the basis of the main lessons learned
from research projects and studies carried out and on the other hand,
through the collection of information from various actors. For this,
we supplemented our own knowledge with a bibliographic work carried
out on the basis of almost 30 major research projects, more than
150 international publications and a collection of information from
a dozen actors in the field via a targeted survey. After describing
the garden ecosystem and the actors involved in it’s functioning,
we present the historical evolution, since the 1990s, of the concepts
and associated approaches. The different compartments of the ecosystem
are then presented, before identifying the main scientific results
obtained and their promotion in the form of approaches and tools
for garden management. (3) Understanding garden soils to better manage
them: main achievements and prospects - The research carried out
has made it possible to acquire knowledge about vegetable gardens,
the agronomic characteristics of their soils, their degree of fertility
and contamination and that of vegetables, exposure to pollutants
from populations associated with gardening and the management measures
to be implemented if necessary. The results of this work demonstrated
the complexity of the "garden" socio-ecosystem, the very high variability
in the quality of soils and crops and the existence of transfers
of certain pollutants within the food chain. Based on the knowledge
limits identified, finalized research perspectives are then proposed
with the aim of informing and training even more the multiple actors
concerned by the challenges linked to vegetable gardens.},

of urban and peri-urban soils, the demand for nature in cities is
regaining real vigour. This is almost unexpected for vegetable gardens.
Indeed, three to four decades ago the cultivation of vegetable gardens
at home or in collective gardens was obsolete, in particular due
to access to fruit and vegetables facilitated by intensive agriculture.
Today, if the economic interest of the vegetable garden continues,
the reasons for this revival are more in the social bond, the practice
of a physical activity or the will to eat healthy. However, the dynamics
of this form of urban agriculture and in particular vegetable gardens
can be translated into hasty projects for which certain elements
of "common sense" would be neglected. Thus, the extension of the
city over the city leads to changes in land use that can, for example,
increase the exposure of populations to pollutants. The compatibility
between the state of the environment and the uses must then be checked;
this exercise is not always easy given the diversity of the situations
encountered. (2) A range of projects and actors: from disciplinary
case studies to multidisciplinary projects - An inventory is proposed,
carried out on the one hand, on the basis of the main lessons learned
from research projects and studies carried out and on the other hand,
through the collection of information from various actors. For this,
we supplemented our own knowledge with a bibliographic work carried
out on the basis of almost 30 major research projects, more than
150 international publications and a collection of information from
a dozen actors in the field via a targeted survey. After describing
the garden ecosystem and the actors involved in it’s functioning,
we present the historical evolution, since the 1990s, of the concepts
and associated approaches. The different compartments of the ecosystem
are then presented, before identifying the main scientific results
obtained and their promotion in the form of approaches and tools
for garden management. (3) Understanding garden soils to better manage
them: main achievements and prospects - The research carried out
has made it possible to acquire knowledge about vegetable gardens,
the agronomic characteristics of their soils, their degree of fertility
and contamination and that of vegetables, exposure to pollutants
from populations associated with gardening and the management measures
to be implemented if necessary. The results of this work demonstrated
the complexity of the "garden" socio-ecosystem, the very high variability
in the quality of soils and crops and the existence of transfers
of certain pollutants within the food chain. Based on the knowledge
limits identified, finalized research perspectives are then proposed
with the aim of informing and training even more the multiple actors
concerned by the challenges linked to vegetable gardens. |

to promote recolonization by pedofauna of isolated and degraded areas.
The experimental study was set up in the former coal mining area
of Northern France. This area is particularly disturbed and fragmented
by land-use change, urbanization, industry, intensive agriculture
and metal pollution. To examine the movements of pedofauna, four
kinds of mulches were applied: (i) Ramial Chipped Wood (RCW), (ii)
chopped Miscanthus, (iii) dead leaves and (iv) wheat straw as well
as plastic sheeting, a material often used in green spaces. A negative
control consisted in soil without mulch addition. The experimental
set-up consisted of a set of 18 bands of mulch (6 m long x 0.5 m
width x 8 cm thick, i.e. a volume of 0.04 m3 per band) installed
on three adjacent plots on a surface area which stretch on 4400 m2:
(i) plot F1, a mixed plantation, (ii) plot M consisted of three rows
of maples (both considered to be the reservoir of biodiversity) and
(iii) plot BF, an ash plantation (with lower biodiversity). Faunistic
communities of soil present within the mulches were monitoring using
pitfall traps for four months (April to July), at a rate of eight
surveys for each of the 90 traps installed, i.e. 720 samples. Different
life traits and indices of diversity were studied, more specifically
on carabid beetles. The main objective of the study was first to
check whether mulches could or not reconnect different planted plots
in a peri-urban landscape highly modified by human activities. The
second aim was to find which type of mulch had the best efficiency
in the recovery of the connectivity between plots. The last questions
were which type of zoological groups could be favoured by the use
of mulches and which benefits for ecosystem functioning. The main
hypotheses of this study were: (i) Organic mulches would act as dispersal
corridors and refuge zones to the soil organisms; (ii) organic mulches
would be attractive to many organisms with various ecological needs.
This study highlighted the potential benefits of using the mulching
technique to support ecological connectivity in disturbed environment
since this method highlighted the presence of individuals with different
diets (saprophagous, predators, phytophagous and so forth), small
and large size species which do not have the same dispersal capacities
as well as species that are more dependent on forest environments
and others that depend on more open environments. The study concluded
that organic mulches are more favourable to pedofauna than soil without
mulch or plastic sheeting. With regard to organic mulches, no difference
was noted, either in terms of cumulative abundance or monthly monitoring.
However, for carabids, it should be noted that dead leaves and wheat
straw have higher specific richness than Miscanthus and RCW.},

Results The study sample of 975 cases of hypospadias over the 13-year
period resulted in an incidence of 25.4/10,000 male births, and was
characterized by significant spatial heterogeneity (p < 0.005) and
autocorrelation (p < 0.001). We detected two high-incidence clusters
that differed with regard to their land use. After the exclusion
of 221 patients with confounding factors, two high-incidence clusters

The first cluster contained a higher median [interquartile range]

“neutral areas” (0.19 [0.08;0.53]) did (p < 0.001). Conversely, the

in the urban cluster (0.47 [0.42;0.55]) and significantly higher

abstract = {Although a growing body of evidence suggests that chronic exposure to outdoor air pollution is linked to a decline in lung function, data on flow at low lung volumes that may be more specific of small airway obstruction are still scarce. We aimed to study the associations between residential exposure to air pollution and lung function, with specific focus on small airways obstruction. We assessed 2995 French participants (aged between 40 and 65) in the ELISABET cross-sectional survey. Residential exposures to nitrogen dioxide (NO2), particulate matter with a diameter <10 μm (PM10) and sulphur dioxide (SO2) were assessed. The spirometric parameters were forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), and forced expiratory flow between 25% and 75% of FVC (FEF25-75) and at 75% of FVC (FEF75).

Although a growing body of evidence suggests that chronic exposure to outdoor air pollution is linked to a decline in lung function, data on flow at low lung volumes that may be more specific of small airway obstruction are still scarce. We aimed to study the associations between residential exposure to air pollution and lung function, with specific focus on small airways obstruction. We assessed 2995 French participants (aged between 40 and 65) in the ELISABET cross-sectional survey. Residential exposures to nitrogen dioxide (NO2), particulate matter with a diameter <10 μm (PM10) and sulphur dioxide (SO2) were assessed. The spirometric parameters were forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), and forced expiratory flow between 25% and 75% of FVC (FEF25-75) and at 75% of FVC (FEF75). Coefficients in linear regression models were expressed as the z-score [95% confidence interval] for an increment of 5 μg/m3 in NO2 and 2 μg/m3 in PM10 and SO2. NO2 was associated with significantly lower values of FEV1 (−0.10 [-0.15;-0.05]), FVC (−0.06 [-0.11;-0.02]), FEV1/FVC (−0.07 [-0.11;-0.03]), FEF25-75 (−0.09 [-0.14;-0.05]) and FEF75 (−0.08 [-0.12;-0.04]). PM10 was associated with significantly lower values of FEV1 (−0.10 [-0.15;-0.04]), FVC (−0.06 [-0.11;-0.01]), FEV1/FVC (−0.06 [‒0.11;-0.01]), FEF25-75 (−0.08 [-0.13;-0.03]) and FEF75 (−0.08 [-0.12;-0.04]). SO2 was associated with significantly lower values of FEV1 (−0.09 [-0.16;-0.02]), FEV1/FVC (−0.07 [-0.13;-0.01]), FEF25-75 (−0.09 [-0.15;-0.02]) and FEF75 (−0.08 [-0.14;-0.03]) but not FVC (−0.05 [-0.11; 0.009]).

was shown to predict the closest results in comparison to our experimental

Neural Network model was designed. The results showed that sewage
sludge supplementation increased the efficiency of theSinapis albaplant
in removing Cd from the soil. After 28 days of exposure, the removal
rate varied from 10.96% without any supplementation to 65.9% after
supplementation with the highest possible (law allowed) dose of sewage
sludge. The comparison proved that the prediction capability of the
ANN model was much higher than that of the RSM model (adjustedR-square:
0.98, standard error of the Cd prediction removal: 0.85 +/- 0.02).
Thus, the ANN model could be used for the prediction of heavy metal
removal during assisted phytoremediation with sewage sludge. Moreover,
such approach could also be used to determinate the dose of sewage

In one dwelling, a very high overall contamination level was found (710–7.240 CFU/m3), with a predominance of A. fumigatus (640–6.490 CFU/m3), and ARAF showing the TR34/L98H mutation was isolated. Mycological follow-up of the patient showed the persistence of H285Y isolates, but no acquisition of TR34/L98H isolates was observed. This could be due to the low proportion of TR34/L98H isolates (<3%), or the establishment of preventative measures and dwelling remediation taken after the environmental investigation. Our data underlines the value of an environmental assessment to establish preventative measures and limit the risk of A. fumigatus exposure and ARAF acquisition. |

the availability of metals, and (iv) increase the ratio values between
potential Lewis acids and Cd or Pb in order to produce biosourced
catalysis. For instance, the real phytoavailability was reduced by
27%–57% and 64.2%–94.8% for Cd and Pb, respectively. Interestingly,
the real phytoavailability of Zn was the highest in the least contaminated
soils. Even if soils were highly contaminated, no visual toxicity
symptoms were recorded in the growing ryegrasses. This indicates
that ryegrass is suitable for the revegetation of contaminated gardens.
To promote the sustainable ryegrass production on contaminated soils
for production of new organic fragrance and drugs in green processes

assisted phytostabilization of the elements, and then assisted phytoextraction

slight variations in pH and significant increases of assimilable

The germination of the ryegrass seeds was favoured with calcium phosphates
regardless the contamination level of the studied soils. No clear
effects of calcium phosphates on the microbial and fungi communities
were detected. In contrast, results indicated relationships between
the physicochemical parameters of soils, their contamination level
and the composition of fungal communities. Indeed, for one of the
soils studied, calcium could limit the transport of nutrients, causing
an increase in fungi to promote again the transfer of nutrients.
Surprisingly, the phytoavailability of Pb increased in the most contaminated
soil after adding dicalcium phosphate and the mixture of phosphates
whereas a slight decrease was highlighted for Cd and Mn. Although
minor changes in the phytoavailability of potentially toxic metals
were obtained using calcium phosphates, the ability of ryegrass to
accumulate Zn and Ca (up to 600 and 20,000 mg kg−1, respectively)
make possible to qualify this plant as a bio ‘ore’ resource.},

The germination of the ryegrass seeds was favoured with calcium phosphates
regardless the contamination level of the studied soils. No clear
effects of calcium phosphates on the microbial and fungi communities
were detected. In contrast, results indicated relationships between
the physicochemical parameters of soils, their contamination level
and the composition of fungal communities. Indeed, for one of the
soils studied, calcium could limit the transport of nutrients, causing
an increase in fungi to promote again the transfer of nutrients.
Surprisingly, the phytoavailability of Pb increased in the most contaminated
soil after adding dicalcium phosphate and the mixture of phosphates
whereas a slight decrease was highlighted for Cd and Mn. Although
minor changes in the phytoavailability of potentially toxic metals
were obtained using calcium phosphates, the ability of ryegrass to
accumulate Zn and Ca (up to 600 and 20,000 mg kg−1, respectively)
make possible to qualify this plant as a bio ‘ore’ resource. |

20 placettes d’une surface de 20 m² ont été définies. Le sol de 10
de ces placettes a été amendé au moyen d’un mélange de biochar de
miscanthus et de compost de déchets verts. Les 10 autres placettes
ont été utilisées comme témoin. A chacune de ces placettes correspond
un type d’ensemencement particulier et un mode de gestion distinct.
Ainsi, diverses essences végétales ont été semées. Il s’agit (1)
d’un mélange d’espèces classiquement mis en oeuvre sur les espaces
verts (ray-grass anglais, fétuque rouge gazonnante, fétuque rouge
traçante et pâturin des prés), (2) d’un mélange d’espèces sélectionnées
pour leurs comportements présumés vis-à-vis des polluants (stabilisation
des polluants métalliques, rhizo/phytodégradation de certains polluants
organiques (ray-grass anglais, agrostide stolonifère, fétuque rouge,
trèfle blanc), et des mêmes espèces en implantation monospécifique
avec (3) un ray-grass, (4) une agrostis stolonifère, (5) un trèfle
blanc, et (6) une fétuque rouge. Une septième modalité correspond
à l’installation d’une végétation spontanée. Aux espèces implantées
en mélange et à la végétation spontanée, correspondent deux modes
de gestion (tonte ou pas du couvert végétal). Durant les trois années
d’expérimentation seront étudiés le comportement des polluants des
sols, les effets des modes de gestion sur les communautés végétales
et d’une façon globale, sur la fonctionnalité des sols. |
