The ubiquitous occurrence of microplastics (MPs) in the marine environment is raising concern for interactions with organisms. These particles efficiently adsorb persistent organic pollutants from surrounding and, due to small size, they are easily available ingestion at all trophic levels. Once ingested, MPs can induce mechanical damage, sub- lethal effects and various cellular responses, further modulated by possible release adsorbed chemicals or additives. In this study, ecotoxicological...
Although microplastics are distributed globally in the marine environment, a great deal of unknowns relating to their ecotoxicological effects on biota remain. Due lipophilic nature, have potential adsorb persistent organic pollutants present contaminated regions, which may increase detrimental impact once assimilated by organisms. This study investigates exposure low-density polyethylene (LDPE) (11 – 13 µm), with and without adsorbed contaminants (benzo[a]pyrene - BaP perfluorooctane...
Microplastics are ubiquitous in aquatic ecosystems, but little information is currently available on the dangers and risks to living organisms. In order assess ecotoxicity of environmental microplastics (MPs), samples were collected from beaches two islands Guadeloupe archipelago, Petit-Bourg (PB) located main island Marie-Galante (MG) second archipelago. These have a similar polymer composition with mainly polyethylene (PE) polypropylene (PP). However, these very dissimilar regard their...
Microplastics (MPs), widely present in aquatic ecosystems, can be ingested by numerous organisms, but their toxicity remains poorly understood. Toxicity of environmental MPs from 2 beaches located on the Guadeloupe archipelago, Marie Galante (MG) and Petit-Bourg (PB) near North Atlantic gyre, was evaluated. A first experiment consisted exposing early life stages zebrafish (Danio rerio) to at 1 or 10 mg/L. The exposure particles water induced no toxic effects except a decrease larval swimming...
Plastic products contain complex mixtures of chemical compounds that are incorporated into polymers to improve material properties. Besides the intentional additives, other including residual monomers and non-intentionnaly added substances (NIAS) as well sorbed pollutants usually also present in aged plastic. Since most these only loosely bound polymer via non-covalently interactions, i.e., van der Waals forces, they may leach surrounding environment. Although there is increasing knowledge...
The sorption processes of persistent organic pollutants on microplastics particles are poorly understood. Therefore, the present study investigated perfluorooctanesulfonate (PFOS) polyethylene (PE) microplastic (MPs) which representing a prominent environmental pollutant and one most abundant polymers in aquatic environment, respectively. focus was set investigation impact particle size PFOS using four different PE MPs ranges. kinetics for 6 months studied with selected range MPs. Besides,...
Marine environments receive plastic waste, where it suffers a transformation process into smaller particles. Among them, microplastics (MPs; <5 mm) are ingested by aquatic organisms leading to negative effects on animal welfare. The interactions between MPs, contaminants and poorly understood. To clarify this issue, European seabass (Dicentrarchus labrax L.) were fed with diets supplemented 0 (control), polyethylene (PE) MPs (100 mg/kg diet), perfluorooctanesulfonic acid (PFOS, 4.83 μg/kg...
As wide-spread pollutants in the marine environment, microplastics (MPs) have raised public concern about potential toxic effects aquatic organisms, and, among others, MPs were suspected to act as a vector for organic biota. The purpose of present study was investigate by three model pollutants, oxybenzone (BP3), benzo[a]pyrene (BaP) and perfluorooctane sulfonate (PFOS) adsorbed polyethylene on basis standard assay, acute fish embryo toxicity test (FET; OECD TG 236) with zebrafish (Danio...
This study investigated the ecotoxicological effects of differently sized (4–6 µm and 20–25 µm) low-density polyethylene (LDPE) microplastics (MPs), with without adsorbed benzo-a-pyrene (BaP), in clam Scrobicularia plana. Biomarkers oxidative stress (superoxide dismutase—SOD; catalase—CAT), biotransformation (glutathione-S-transferases—GST), damage (lipid peroxidation—LPO) neurotoxicity (acetylcholinesterase—AChE) were analysed gills digestive glands at different time intervals for a total...
Transgenerational effects induced by environmental stressors are a threat to ecosystems and human health. However, there is still limited observation understanding of the potential chemicals influence life outcomes over several generations. In present study, we investigated two contaminants, coumarin 47 permethrin, on exposed zebrafish (F0) their progeny (F1–F3). Coumarin commonly found in personal care products dyes, whereas permethrin used as domestic agricultural pyrethroid...
The characterization of microplastic (MP) contamination in marine species is increasing as concerns about environmental and food safety are more discussed. Here, we reported a quantitative qualitative assessment the by anthropogenic particles (from visual sorting; AP) MP (plastic-made) whole soft body or digestive tract species. Four commercial were studied, namely Pacific oyster (Magallana gigas), spiny spider crab (Maja sp.), common sole (Solea solea) seabass (Dicentrarchus labrax...
Abstract Chlorpyrifos (CPF), an organophosphorous pesticide, can be found in aquatic ecosystems at concentrations of up to several hundred nanograms per liter because water runoff from treated crops. While some studies have shown that low CPF may adverse effects on species, comparatively little is known about its effect fish embryos and larvae. To investigate the developmental CPF, rainbow trout ( Oncorhynchus mykiss ) eyed‐stage were exposed semistatic conditions 0.3 3 µg/L end sac‐fry...
The aim of this study was to analyze the impact three concentrations a pesticide mixture on first development stages rainbow trout (Oncorhynchus mykiss). made up commonly used pesticides in viticulture: glyphosate (GLY), chlorpyrifos (CPF) and copper sulfate (Cu). Eyed stage embryos were exposed for 3 weeks mixture. Lethal sub-lethal effects assessed through number phenotypic molecular endpoints including survival, hatching delay, success, biometry, swimming activity, DNA damage (Comet...
