has been suffering for more than a century for atmospheric emissions
from two smelters present in the area. In this site, soils present
a concentration of heavy metal which is 20 to 50 times higher than

differences in almost each biomarker considered, demonstrating lower
metal uptake, better adaptation, and a lower stress level in plants

several months, plants in pots demonstrated stress even in control
samples compared to the in situ plants. This suggests that pot experiments
do not reveal what happens on the field, by overestimating plant
metal uptake capacity but also by modifying plant response to metal
stress. This work demonstrates the importance of leading in situ
experiment to understand fully how plants behave and adapt to site

quantifier les transferts hydro-sédimentaires sur deux années hydrologiques

abstract = {Background: Since the 1990s, technical developments and theoretical
studies of columns packed with core-shell and sub-core-shell particles
demonstrated improved efficiency separation, time reduction, solvent
use than fully porous columns. Thanks to this chromatographic system,
environmental pollutants are being analysed under green conditions.
Objective: This paper presents theoretical aspects and a review of
the main features of core-shell technology focusing essentially on
environmental applications.
Method: The main advantages of core-shell columns may be summarized
as follows: i) reduction of the eddy dispersion A term; ii) homogeneity
of the particle size distribution reducing the velocity bias; (iii)
superior mass transfer kinetics; iv) better performance of the separation
(faster and greater).
Results: Systematic comparisons with fully porous particles undeniably
highlighted the benefits of core-shell technology in the separation
of a great number of pollutants and “micropollutants” of different
molecular weights which surround us and have an impact on the ecosystem.
Conclusion: Core-shell particles are emerging as green substrates
for the analysis of chemical species problematic for environment.
The environmental gain in terms of limitation of analysis time and
solvent consumption has been demonstrated. The current manuscript
proposes an update of the literature devoted to the use of core-shell
particles in environmental applications. Future trends in the field

abstract = {The degree of recrystallization of carbonaceous material (CM), as
monitored by Raman microspectroscopy, was examined as a function
of metamorphic grade in two well-studied contact aureoles containing
carbonaceous pelites: the Nelson aureole, British Columbia and the
Ballachulish aureole, Scotland. Here, we use (a) the R2 ratio extracted
from the Raman spectrum of CM as a proxy for the degree of graphitization
(0.0 in perfect graphite then increasing with structural defects)
and (b) the second-order S1 band (similar to 2,700 cm(-1)) as a marker
for the tridimensional ordering of CM. The Nelson aureole (garnet-staurolite-andalusite-sillimanite-K-feldspar
sequence, similar to 550-650 degrees C, 3.5-4.0 kbar) was developed
in rocks that were unmetamorphosed prior to contact metamorphism,
whereas the Ballachulish aureole (cordierite-andalusite-K-feldspar-sillimanite
sequence, similar to 550-700 degrees C, similar to.0 kbar) was developed
in rocks that had been metamorphosed to garnet grade conditions (similar
to 7 kbar, similar to 500 degrees C) c. 45 Ma before contact metamorphism.
Thirty-one samples were examined from Nelson and 29 samples from
Ballachulish. At Nelson, the R2 ratio steadily decreases from similar
to 0.25 to 0.0 as the igneous contact is approached, whereas at Ballachulish,
the R2 ratio remains largely unchanged from regional values (similar
to 0.20-0.25) until less than 100 m from the igneous contact. The
second-order S1 band reveals that carbonaceous material (CM) was
transformed to highly "ordered" locally tridimensional graphitic

The degree of recrystallization of carbonaceous material (CM), as
monitored by Raman microspectroscopy, was examined as a function
of metamorphic grade in two well-studied contact aureoles containing
carbonaceous pelites: the Nelson aureole, British Columbia and the
Ballachulish aureole, Scotland. Here, we use (a) the R2 ratio extracted
from the Raman spectrum of CM as a proxy for the degree of graphitization
(0.0 in perfect graphite then increasing with structural defects)
and (b) the second-order S1 band (similar to 2,700 cm(-1)) as a marker
for the tridimensional ordering of CM. The Nelson aureole (garnet-staurolite-andalusite-sillimanite-K-feldspar
sequence, similar to 550-650 degrees C, 3.5-4.0 kbar) was developed
in rocks that were unmetamorphosed prior to contact metamorphism,
whereas the Ballachulish aureole (cordierite-andalusite-K-feldspar-sillimanite
sequence, similar to 550-700 degrees C, similar to.0 kbar) was developed
in rocks that had been metamorphosed to garnet grade conditions (similar
to 7 kbar, similar to 500 degrees C) c. 45 Ma before contact metamorphism.
Thirty-one samples were examined from Nelson and 29 samples from
Ballachulish. At Nelson, the R2 ratio steadily decreases from similar
to 0.25 to 0.0 as the igneous contact is approached, whereas at Ballachulish,
the R2 ratio remains largely unchanged from regional values (similar
to 0.20-0.25) until less than 100 m from the igneous contact. The
second-order S1 band reveals that carbonaceous material (CM) was
transformed to highly "ordered" locally tridimensional graphitic
carbon at Ballachulish by regional metamorphism prior to contact
metamorphism, whereas CM was still a disordered turbostratic (bidimensional)
material before contact metamorphism in the case of Nelson. Pretexturation
of CM likely induced sluggish recrystallization of CM and delayed
graphitization in the Ballachulish aureole. Temperatures of recrystallization
of the CM in the two aureoles were estimated using different published

have rather recorded several stages of the retrograde path, through

a distinct behaviour between the northern and southern part of the

C for maximum P-T (estimated with conventional thermometers), to
similar to 0.8 kbar and similar to 220 degrees C according to chlorite
crystal core analysis, and to similar to 0.3 kbar and similar to
190 degrees C according to chlorite crystal-rim analysis. On the
contrary, the north of the Glarus area shows an apparent break in
the exhumation, with P estimates from chlorite crystal rims (similar
to 1.3 kbar) higher than from chlorite crystal cores (similar to
0.8 kbar). Even if the absolute pressure values are fraught with
large uncertainty, their contrasting core/rim pattern is not model
dependent. We try to correlate these new thermobarometric results
with independent data to refine the exhumation scenario of the North
Helvetic flyschs, confirming differential uplift along the transect.
