Assessment of the effects in mussels (Mytilus edulis) chronically exposed to en...

Background: The presence of metallic nanoparticles (NP) in the aquatic environment is a cause for concern as they can have adverse effects on biota [1,2]. Objective: The purpose of this study was to evaluate the effect on mussels (Mytilus edulis) chronically exposed to environmentally realistic concentrations of nickel nanoparticles using oxidative stress and lipid peroxidation biomarkers. Methods: In this stud...

Assessment of paracetamol toxic effects under varying seawater pH conditions on...

Increasing atmospheric carbon dioxide (CO2) levels are likely to lower ocean pH values, after its dissolution in seawater. Additionally, pharmaceuticals drugs are environmental stressors due to their intrinsic properties and worldwide occurrence. It is thus of the utmost importance to assess the combined effects of pH decreases and pharmaceutical contamination, considering that their absorption (and effects) ar...

Toxicity of two drugs towards the marine filter feeder Mytilus spp, using bioch...

The increasing presence of anthropogenic contaminants in the environment may constitute a challenge to non-target biota, considering that most contaminants can exert deleterious effects. Salicylic acid (SA) is a non-steroid anti-inflammatory drug (NSAID) which exerts its activity by inhibiting the enzyme cyclooxygenase (COX). Another class of drugs is that of the diuretics, in which acetazolamide (ACZ) is inclu...

Evaluation of single and combined effects of two pharmaceuticals on the marine ...

Pharmaceutical drugs are among the most used chemicals for human and veterinary medicines, aquaculture and agriculture. Pharmaceuticals are environmentally persistent, biologically active molecules, thereby having the potential to exert biological effects on non-target species. Among the most used pharmaceuticals, one may find salicylic acid (SA), a non-steroid anti-inflammatory drug (NSAID) that acts by inhibi...

Toxic effects of environmentally realistic concentrations of diclofenac in orga...

Single and combined effects of the drugs salicylic acid and acetazolamide: Adve...

Pharmaceutical drugs are among the most used chemicals, for human and veterinary medicines, aquaculture and agriculture. Pharmaceuticals are biologically active molecules, having also environmental persistence, thereby exerting biological effects on non-target species. Among the most used pharmaceuticals, one may find salicylic acid (SA), a non-steroid anti-inflammatory drugs (NSAIDs), and acetazolamide (ACZ), ...

Multi-parametric analysis of ciprofloxacin toxicity at ecologically relevant le...

The increased presence of emergent compounds, such as pharmaceuticals drugs, in the aquatic compartment has been acknowledged as an evolving environmental issue whose consequences are not yet fully characterized. Specific classes of pharmaceutical drugs, such as fluoroquinolone antibiotics, can exert toxic effects to non-target species with ecological significance, since these compounds are environmentally stab...

Effects of pH on salicylic acid toxicity in terms of biomarkers determined in t...

Alterations of the physical-chemical properties of the oceans due to anthropogenic activities are, at present, one of the most concerning environmental issues studied by researchers. One of these issues is ocean acidification, mainly caused by overproduction and release of carbon dioxide (CO2) from anthropogenic sources. Another component of environmental degradation is related to the production and release of ...

Acute and chronic effects of paracetamol exposure on Daphnia magna: how oxidati...

The modern usage of pharmaceutical drugs has led to a progressive increase in their presence and environment concentrations, particularly in the aquatic compartment which is the most common final dumping location for this specific class of chemicals. These substances, due to their chemical and biological properties, can exert mostly uncharacterized toxic effects to non-target aquatic species, given the diverse ...
