Pharmaceuticals and personal care products (PPCPs) have been detected in several aquatic ecosystems for a number of years, but the potential for biological effects in exposed non-target organisms is only now being reported. In this study the potential cellular damage due to two of the main PPCPs found in aquatic environments was investigated by in vitro(More)
In this work, we investigated the possible genotoxic and cytotoxic effects of the antibacterial agent Triclosan in hemocytes of the freshwater bivalve Zebra mussel (Dreissena polymorpha). For this study, we used several biomarkers for in vivo experiments (96h of exposure) carried out at three possible environmental Triclosan concentrations (1, 2, 3nM). We(More)
The sub-lethal effects induced by the non-steroidal anti-inflammatory drug ((NSAID) ibuprofen (IBU; ((±)-2-(p-isobutylphenyl) propionic acid))) were investigated using a battery of biomarkers on the freshwater bivalve Dreissena polymorpha. According to the results from a semi-static in vivo approach, mussels were exposed for 96 h to increasing levels of(More)
Polybrominated diphenyl ethers (PBDEs) are a group of highly hydrophobic and persistent chemicals that has been used as flame retardants in several industrial applications. They have been detected in various environmental matrices worldwide and an increasing number of studies have recently been carried out to investigate their potential toxicity on(More)
The aim of this paper was to obtain the first screening ecotoxicological risk evaluation in the Sunderban wetlands, the largest prograding delta in the estuarine phase of the River Ganges. The characterization of exposure was conducted by means of an extensive survey of several persistent organic pollutants (PAHs, PCBs, DDTs, PBDEs, HCHs, HCB) measured in(More)
The paper presents the first comprehensive survey of congener profiles (12 congeners) of polybrominated diphenyl ethers (PBDEs) in core sediment samples (<63 microm) covering seven sites in Sundarban mangrove wetland (India). Gas-chromatographic analyses were carried out in GC-Ms/Ms for tri- to hepta- brominated congeners. Results pointed out a(More)
This study investigates contamination by 13 polybrominated diphenyl ether (PBDE) congeners in a high-mountain pasture located in the Italian Alps. The trend of PBDE contamination in three soil layers was investigated by a spring-summer sampling period to understand the importance of different environmental variables, such as seasonality, topographical(More)
Pharmaceutical compounds are considered the new environmental pollutants but at present few studies have evaluated their ecotoxicity on aquatic invertebrates. This study was aimed to investigate the in vitro cytotoxicity of four common drugs, namely atenolol (ATL), carbamazepine (CBZ), diclofenac (DCF) and gemfibrozil (GEM), on three different cell(More)
This paper presents the first comprehensive report of the organochlorine pesticide residues (OCs) such as hexachlorocyclohexane isomers (HCHs), dichlorodiphenyltrichloroethane and its six metabolites (DDTs), and hexachlorobenzene (HCB) in core sediments (<63-microm particle size) from the Indian Sunderban wetland. The pooled mean values of the mass fraction(More)
Perfluooctane sulfonate (PFOS) is considered an emerging pollutant because of its wide distribution in both aquatic and terrestrial ecosystems, as well as its potential toxicity to living organisms. Although PFOS environmental levels and the adverse effects on classical model organisms in toxicological studies are well known, including developmental(More)
