Abstract Stable isotope analysis provides a powerful tool to identify the energy sources which fuel consumers, understand trophic interactions and infer consumer position (TP), an important concept that describes ecological role of consumers in food webs. However, current methods for estimating TP using stable isotopes are limited do not fulfil complete potential isotopic approach. For instance, researchers typically use point estimates key parameters including discrimination factors...
The use of freshwater invertebrates for biomonitoring has been increasing several decades, but little is known about relations between external exposure concentration metals and their biodistribution among different tissues. One multi-compartments toxicokinetic (TK) models are powerful tools to formalize predict how a contaminant bioaccumulated. aim this study develop modeling approaches improve knowledge on dynamic accumulation fate Cd Hg in gammarid's organs. Gammarids were exposed...
Reproduction data collected through standard bioassays are classically analyzed by regression in order to fit exposure-response curves and estimate ECx values (x% effective concentration). But is often misused on such data, ignoring statistical issues related (i) the special nature of reproduction (count data), (ii) a potential inter-replicate variability, (iii) possible concomitant mortality. This paper offers new insights dealing with those issues. Concerning mortality, particular...
Cadmium sulfide (CdS) quantum dots have a number of current applications in electronics and solar cells significant future potential medicine. The aim the present study was to examine toxic effects CdS on marine clam Scrobicularia plana exposed for 14 d these nanomaterials (10 µg Cd L(-1) ) natural seawater compare them with soluble Cd. Measurement labile released from showed that 52% remained nanoparticulate form. Clams accumulated same levels regardless form which it delivered (soluble vs...
Nowadays, biomarkers are recognized as valuable tools to complement chemical and ecological assessments in biomonitoring programs. They provide insights into the effects of contaminant exposures on individuals establish connections between environmental pressure biological response at higher levels. In last decade, strong improvements design experimental protocols result interpretation facilitated use biomarker across wide geographical areas, including aquatic continua. Notably, statistical...
Abstract Interspecies differences in contaminant sensitivity are measured to assess environmental risk based on species distribution. The present study was intended demonstrate the importance of studying effects contaminants life‐history traits various species. To do this, we compared ivermectin survival, growth, and reproduction two cladoceran ( Daphnia magna Ceriodaphnia dubia ) strains D. (one Japanese one European). Ivermectin is widely used against endo‐ ectoparasites livestock pets...
Today, only few ready-to-use and convenient decision-making tools are available in ecotoxicology concerning accumulation effects of chemical substances on organisms, accounting for exposure situations that known to be complex (routes exposure, metabolism, mixtures, etc.). This paper presents new perspectives the generic calculation bioaccumulation metrics via innovative web tool MOSAICbioacc (http://mosaic.univ-lyon1.fr/bioacc). provides all kinds associated with their uncertainty whatever...
This work quantified the accumulation efficiencies of Hg in cuttlefish, depending on both organic (MeHg) and inorganic (Hg(II)) forms, under increased pCO2 (1600 μatm). Cuttlefish were fed with live shrimps injected two stable isotopic tracers (Me202Hg 199Hg(II)), which allowed for simultaneous quantification internal accumulation, Hg(II) methylation, MeHg demethylation rates different organs. Results showed that had no impact bioaccumulation organotropism, did not influence microbiota...
Information on the relationship between exposure concentrations of metals and their biodistribution among organs remained scarce in invertebrates. The objective this study was to investigate effects Cd concentration organotropism, toxico-kinetic fate metal different gammarids exposed dissolved radioisotope 109Cd. Gammarids male were for 7 days three environmental (i.e. 4, 52 350 ng.L-1) before being placed depuration conditions uncontaminated water). At several sampling times, determined by...
