Microplastics and heavy metals in freshwater fish species in the southwestern region of Bangladesh: An emerging concern for public health

Emerging contaminants, Journal Year: 2024, Volume and Issue: 10(3), P. 100325 - 100325

Microplastics (MPs) pollution and its associated toxicity raising concerns among scientists as a result of their toxicological impacts on human health the ecosystem. This study aims to investigate microplastics heavy metals (HMs) contamination in seventeen freshwater fish species collected from Southwestern region Bangladesh. extracted these using hydrogen peroxide digestion method characterized by Attenuated Total Reflection- Fourier Transform Infrared Spectroscopy (ATR-FTIR). Atomic Absorption (AAS) was used determine concentration HMs different for evaluating risks. A total 142 microplastic particles were with an average 1.13 ± 0.84 items per individual fish, where highest found C. punctata (3.43 3.15 items) lowest A. mola (0.14 0.38 items). Identified dominated < 1 mm size (87.3%), black color (60.6%), fiber shape (94.4%). Polyethylene (73.08%), polypropylene (21.15%), polystyrene (5.77%) most prevalent identified polymers. positive correlation between numbers weight length. Low moderate risks microplastics. The (mg/kg) studied samples Cr (0.47–2.89; 0.79 0.56) > Cu (0.01–1.14; 0.50 0.44) Pb (0.04–0.58; 0.22 0.12) Cd (0.00–0.11; 0.03 0.03), respectively. Heavy metals-based risk assessment results show that there are no major non-carcinogenic (THI<1), while higher carcinogenic present consumers.

Microplastic contamination in commercial fish feeds: A major concern for sustainable aquaculture from a developing country

Ecotoxicology and Environmental Safety, Journal Year: 2023, Volume and Issue: 267, P. 115659 - 115659

Plastic pollution has become a global issue nowadays. Due to the increased population in developing countries, we largely depend on fish from our aquaculture industry meet required protein demand. Though several studies documented plastic ingestion freshwater and marine organisms, very limited have been conducted elucidate microplastic (MP) contamination commercial feed. Therefore, this study was designed identify, quantify, characterize microplastics (MPs) feeds Bangladesh assess possible health risks consuming different feeds. All feed samples were 100 % contaminated with MPs, where mean abundance of MPs ranged between 500 2200 MPs/kg. No significant differences among types (e.g., starter, grower, finisher) observed terms (F = 0.999, p 0.385). This revealed that fiber most dominant shape (90 %), while color red (34 followed by black (31 %) blue (19 %). The 100–1500 µm size class covers 88 total collected samples. Identified polymers polyethylene (PE, 37.71 polyvinyl chloride (PVC, 27.14 polypropylene (PP, 22.08 terephthalate (PET, 13.07 respectively, PE PVC fall under risk category IV V. Pollution load index (PLI) values all <10, indicating I (low risk). highly recommended avoiding materials packaging storing purposes ingredients mills ensure contamination-free for sustainable aquaculture.

The aquaculture industry is growing rapidly and plays a huge role in bridging the global demand gap for fish other aquatic foods. It vital contributor of valuable nutrients economic benefits. Aquaculture fisheries provide means livelihood to an estimated 58.5 million people globally, according United Nations Food Agriculture Organisation. However, sector impacted by ubiquity microplastics toxic chemicals. Although many studies have reported plastic pollution environment, less attention has been paid coexistence chemicals with particles climate change food contamination. This review evaluates occurrence organisms, feeds, water, sediment ecosystem detection hazardous effects chemical contaminants.
