Exposure of aquatic environments to emerging contaminants is a global issue, special relevant in many estuaries due impacts from anthropogenic activity. The aim this work was evaluate thirty-seven endocrine disruptor chemicals (EDCs) four different classes (pesticides, bisphenols, polycyclic musks and UV-filters) water sediment samples collected during one-year the Tagus Douro Rivers located into NE Atlantic Ocean coast. EDCs analysis achieved afterward validation gas-chromatography mass spectrometry (GC-MS) method using Dispersive Liquid-Liquid Microextraction (DLLME) as extraction procedure for samples, Quick, Easy, Cheap, Efficient, Rugged Safe (QuEChERS) combined with DLLME sediments. estuary presented higher levels contamination pesticide residues bisphenols (BPs) than both samples. Contrariwise, frequency (PCMs) UV-filters (UVF) were slightly estuary. Levels PCMs UVF warmer seasons (summer spring) colder ones (winter autumn). opposite found what respect BPs Although each contaminant are low, usually order few ng/mL(g), presence high number toxic compounds source concern requires constant monitoring.

Cocktail effects of tire wear particles leachates on diverse biological models: A multilevel analysis

Journal of Hazardous Materials, Journal Year: 2024, Volume and Issue: 471, P. 134401 - 134401

Tire wear particles (TWP) stand out as a major contributor to microplastic pollution, yet their environmental impact remains inadequately understood. This study delves into the cocktail effects of TWP leachates, employing molecular, cellular, and organismal assessments on diverse biological models. Extracted in artificial seawater analyzed for metals organic compounds, leachates revealed presence polyaromatic hydrocarbons 4-tert-octylphenol. Exposure (1.5 1000 mg peq L−1) inhibited algae growth induced zebrafish embryotoxicity, pigment alterations, behavioral changes. Cell painting uncovered pro-apoptotic changes, while mechanism-specific gene-reporter assays highlighted endocrine-disrupting potential, particularly antiandrogenic effects. Although heavy like zinc have been suggested players leachate toxicity, this emphasizes water-leachable compounds primary causative agents observed acute toxicity. The findings underscore need reduce pollution aquatic systems enhance regulations governing highly toxic tire additives. pose significant threat, contributing releasing harmful chemical contaminants. unveils hazardous nature introducing detrimental ecosystems. Identified pollutants, notably hydrocarbons, induce impede growth, alter behavior, disrupt signaling pathways. These revelations emphasize material affecting life at multiple levels, posing risks health both ecosystems and, potentially, human well-being. Enhancing our understanding mechanisms is crucial mitigating these safeguarding from deleterious
