Abstract This paper presents the reviews of scientific papers published in 2018 issues on effects anthropogenic pollution aquatic organisms dwelling freshwater ecosystem at global scale. The first part study provides summary relevant literature followed by field and survey based studies. second is categories different classes/sources pollutants which affect organism. composed several sections including metals metalloids, wastewater effluents, sediments, nutrients, pharmaceuticals, polycyclic aromatic hydrocarbons, flame retardants, persistent organic pollutants, pharmaceuticals illicit drugs, emerging contaminants, pesticides, herbicides, endocrine disruptors. final highlights research work new such as microplastics engineered nanoparticles organisms. Practitioner points Heavy concentrations should be assessed nano‐scale environment. Air could have long‐term ecosystem. Future studies focus bioremediations pollution.

A Highly Stable Metal–Organic Framework-Engineered FeS₂/C Nanocatalyst for Heterogeneous Electro-Fenton Treatment: Validation in Wastewater at Mild pH

Environmental Science & Technology, Journal Year: 2020, Volume and Issue: 54(7), P. 4664 - 4674

Published: Feb. 28, 2020

Herein, the novel application of FeS2/C nanocomposite as a highly active, stable, and recyclable catalyst for heterogeneous electro-Fenton (EF) treatment organic water pollutants is discussed. The simultaneous carbonization sulfidation an iron-based metal–organic framework (MOF) yielded well-dispersed pyrite FeS2 nanoparticles ∼100 nm diameter linked to porous carbon. XPS analysis revealed presence doping N atoms. EF with IrO2/air-diffusion cell ensured complete removal antidepressant fluoxetine spiked into urban wastewater at near-neutral pH after 60 min 50 mA 0.4 g L–1 optimum dose. clear enhancement catalytic activity stability material compared natural was evidenced, deduced from its characterization before use. final solutions contained <1.5 mg dissolved iron became progressively acidified. Fluorescence excitation–emission spectroscopy parallel factor demonstrated large mineralization all components 6 h, which accompanied by substantial decrease toxicity. A mechanism •OH dominant oxidant proposed: core–shell served Fe2+ shuttles homogeneous Fenton's reaction provided active sites Fenton process, whereas nanoporous carbon allowed minimizing mass transport limitations.

An introduction to the sources, fate, occurrence and effects of endocrine disrupting chemicals released into the environment

Environmental Research, Journal Year: 2022, Volume and Issue: 207, P. 112658 - 112658

Published: Jan. 4, 2022

Many classes of compounds are known or suspected to disrupt the endocrine system vertebrate and invertebrate organisms. This review sources fate selected disrupting chemicals (EDCs) in environment includes that "legacy" contaminants, as well contaminants emerging concern. EDCs included for discussion organochlorine compounds, halogenated aromatic hydrocarbons, brominated flame retardants, per- polyfluoroalkyl substances, alkylphenols, phthalates, bisphenol A analogues, pharmaceuticals, drugs abuse steroid hormones, personal care products, organotins. An exhaustive survey these all environmental media (e.g., air, water, soil, biota, foods beverages) is beyond scope this review, so priority highlight which there a clear link between exposure effects humans biota from other taxa. Where appropriate, linkages also made regulatory limits such quality guidelines water sediments total daily intake values humans.

Acute effects of neonicotinoid insecticides on Mytilus galloprovincialis: A case study with the active compound thiacloprid and the commercial formulation calypso 480 SC

Ecotoxicology and Environmental Safety, Journal Year: 2020, Volume and Issue: 203, P. 110980 - 110980

Published: July 20, 2020

Pesticides can enter aquatic environments potentially affecting non-target organisms. Unfortunately, the effects of such substances are still poorly understood. This study investigated active neonicotinoid substance thiacloprid (TH) and commercial product Calypso 480 SC (CA) (active compound 40.4% TH) on Mytilus galloprovincialis after short-term exposure to sublethal concentrations. Mussels were tested for seven days 0, 1, 5 10 mg L-1 TH 10, 50 100 CA. For this purpose, several parameters, as cell viability haemocytes digestive cells, biochemical haemolymph features, superoxide dismutase (SOD) catalase (CAT) enzymatic activity gills gland, well histology tissues analysed. The concentrations both lead abatement or completely stopping byssal fibres creation. Biochemical analysis showed significant changes (P < 0.01) in electrolytes ions (Cl-, K+, Na+, Ca2+, S-phosphor), lactate dehydrogenase (LDH) enzyme glucose concentration following substances. TH-exposed mussels imbalance 0.05) CAT gland gills. CA caused decrease SOD tissues. Results histological analyses severe damage a time- concentration-dependent manner. provides useful information about acute toxicity insecticide mussels. Nevertheless, considering that neonicotinoids widely used very important species marine environment human consumption, further researches needed better comprehend potential risk posed by compounds species.
