This study provides the first geographic and temporal large-scale analysis of Cu stable isotope compositions in indigenous oysters to biomonitor anthropogenic inputs aquatic systems. It includes oyster samples from French marine environments with distinct Cu-pollution levels histories extends over several decades biomonitoring. Sample series composed same season similar size/age intended avoid ...

Legacy mercury (Hg) exists in Upper St. Lawrence River wetland hydric soils and is impacted by a new water level management plan (established 2017) implemented to restore biodiversity reduce the monotypic nature of riparian wetlands, currently dominated Typha spp.. The distribution Hg within various components provides insight into potential impacts fluctuations. Hydric soil represents 83% burd...

Algal species which are ubiquitous along the coastlines of many countries reflect the environmental conditions of the coastal seawater and may serve as useful biomonitors of anthropogenic pollution. Heavy metal concentrations of ten elements (As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn) of potential environmental concern were determined in seawater, sediments and twelve species of benthic marine ...

Thallium is one of the most toxic elements, without known biological function in living beings. While contents of other heavy metals like Cd, Hg and Pb are subject to strict limitations in foodstuffs and medicinal plants, and concentrations are routinely checked, in the case of Tl there are no regulations in prime matters intended for phytomedicines, and its monitorization is not performed. The...

INTRODUCTION The model organism Caenorhabditis elegans is widely used for genetic studies as well as a living biomonitor in ecotoxicology. In this study, we investigated whether C. elegans may represent a suitable model for rapid preliminary toxicity studies of pharmaceutical compounds. METHODS For this purpose, we used the EGFR kinase inhibitors BIBU1361, BIBX1382, and an inactive chemical a...

Chloronitrobenzenes (CNBs) are important intermediates for the production of dyes, pesticides, rubber chemicals, and drugs. 2CNB and 4CNB are possible human carcinogens. Therefore, it is important to develop methods to biomonitor people exposed to these occupational and environmental pollutants. We developed a method to determine hemoglobin (Hb) adducts of CNBs. Nitrobenzenes and the resulting ...
