A serious global problem, air pollution poses a risk to both human and environmental health. It contains hazardous material like heavy metals, nanoparticles, others that can create an impact on land marine environments. Particulate pollutants, which enter water systems through variety of ways, including precipitation industrial runoff, have particularly adverse influence aquatic invertebrates. Once in the water, these particles harm invertebrates physically, physiologically, molecularly, resulting developmental problems multi-organ toxicity. Further research at cellular molecular levels numerous locations world is necessary completely understand impacts particle Understanding how affects vital as significance ecotoxicological studies particulate contaminants increases. This review gives comprehensive overview current understanding

Chlorpromazine's impact on Mytilus galloprovincialis: a multi-faceted investigation

Chemosphere, Год журнала: 2023, Номер 350, С. 141079 - 141079

The antipsychotic chlorpromazine (Cpz) has raised concern as a pharmaceutical effluent due to its wide medical applications. Moreover, potent pro-oxidant properties and impact on the cell viability of marine mollusc Mytilus galloprovincialis, even at low concentrations (ng/L), have been noted. Based this evidence, in study, we investigated physiological effects Cpz M. elucidate fate within organism, terms bioaccumulation, biotransformation, byssus changes stress responses cellular thiolome. Histological indicators vitality analyses were also performed better evaluate influence drug morphology digestive gland. To end, two different (Cpz I (12 ng/L or 37 pM) II μg/L nM)) administered mussels over 14 days. accumulation gland significantly increased with water concentration (BCF II). Biochemical indicated lysosomal dysfunction, reflected elevated total Cathepsin D activity compromised membrane stability. Stress-related metal-buffering proteins (GST metallothionein) responded both concentrations. induced phase biotransformation (CYP450-dependent EROD), while triggered caspase-3 activation, indicative detoxification overload. analysis revealed atrophy, epithelial thinning, haemocyte infiltration, brown presence. Byssus showed significant alterations. In conclusion, our study underscores Cpz-induced histological posing potential implications for mussel health confirming utilisation an indication ecotoxicity.

Drugs are chemical compounds used to treat and improve organic dysfunctions caused by diseases. These include analgesics, antibiotics, antidepressants, antineoplastics. They can enter aquatic environments through wastewater streams, where their physico-chemical properties allow metabolites distribute accumulate. Current climate change associated extreme weather events may significantly impact these substances' toxicity organisms' sensitivity. Among the chemicals present in is non-steroidal anti-inflammatory drug diclofenac (DIC), which EU monitors due its concentration levels. This study investigated influence of temperature (control at 17 °C vs. 21 °C) on effects DIC (0 μg/L 1 μg/L) mussel species Mytilus galloprovincialis. Significant results were observed between °C. Organisms exposed higher showed a decrease several parameters, including metabolic capacity detoxification, particularly with prolonged exposure. However, some after days, M. galloprovincialis no differences from control, indicating adaptation stress. The this confirm that concentrations environment, when combined increased temperatures, produce oxidative stress adversely affect biochemical physiological performance. also validates as bioindicator for assessing environmental contamination DIC. Beyond direct organisms, presence pharmaceuticals like environment highlights interconnectedness human, animal, ecosystem health, underscoring One Health approach understanding mitigating pollution.
