Multiple endpoints of polylactic acid biomicroplastic toxicity in adult zebrafish (Danio rerio).

Although the toxicity of conventional microplastic types (i.e., petroleum derivatives) in different organisms is already known, knowledge about the effects of alternative biopolymers on aquatic vertebrates remains incipient.

How leachates from wasted cigarette butts influence aquatic life? A case study on freshwater mussel Anodontites trapesiali.

There are several reports on the damage smoking causes to human health available in the literature, but little is known about the environmental and biological consequences from inappropriate cigarette butt (CB) disposal in urban and natural environments. The immunotoxic, morphotoxic and mutagenic potential of leachates from cigarette butts (LCB) diluted at environmentally relevant rates (LCB1x: 1.375%; LCB10x: 13.

Behavioral toxicity of tannery effluent in zebrafish (Danio rerio) used as model system.

The ecotoxicity of untreated tannery effluent (UTE) in several animal models has been reported; however, its effects on fish behavior, and neurotoxicity, remain unknown. Thus, the hypothesis that the chronic exposure to UTE can induce behavioral changes in adult zebrafish (Danio rerio) representatives, even when it is highly diluted in water, was tested. Animals exposed to 0.

Cigarette butt leachate as a risk factor to the health of freshwater bivalve.

The toxicity caused by smoking to human health has been demonstrated in several scientific studies. However, little attention has been given to damages caused to aquatic biota when cigarette butts (CB) are disposed of on water surface. Thus, the main aim of the current study is to evaluate the behavioural toxicity of cigarette butt leachates (CBL) in freshwater bivalve species Anodontites trapesialis exposed to different environmentally-relevant dilutions (CBL1x = 1.

Analysis of ZnO nanoparticle-induced changes in Oreochromis niloticus behavior as toxicity endpoint.

The toxicity of zinc oxide nanoparticles (ZnO NPs) has been investigated in different animal models. However, concentrations tested in most studies are often much higher than the ones potentially identified in the environment. Therefore, such toxicity limits the application of these studies to evaluate ecotoxicological risks posed by these nanopollutants.
