Additionally, two (2) water samples were obtained from a nearby drinking water treatment plant (DWTP), also in triplicate. We further assessed the risks associated with microplastic contamination by calculating the pollution load index of the twelve sampling sites. The mean concentration of MPs in the Buriganga and Shitalakshya rivers was 12.4 p/L and 11.5 p/L, respectively; the MPs are mostly of transparent color (69%), in the shape of microfilms (71%), and < 1 mm in size (>90%).

Polypropylene and polyethylene were identified as the most prevalent polymer kinds through analysis of infrared spectra, and the carbonyl index suggested that particles had undergone aging. A novel approach was taken to compute the pollution load index (PLI), which was subsequently employed for estimating the associated ecological risk.

Monthly samples were collected from six SMPs between May 2022 and June 2023. Microalgae composition exhibited dynamic temporal changes in each pond and significant spatial heterogeneity across the ponds. This study is the first to document the widespread presence of HABs in SMPs under different marsh management regimes in this region.

The findings indicated a significant increase in protein and fat in cooked shrimp (p < 0.05) due to moisture loss. However, macronutrients such as Ca and Mg were notably reduced during cooking, except for boiled shrimp. Boiling and grilling significantly reduced both essential and non-essential amino acids, such as histidine, serine, and tyrosine, whereas microwaving and frying decreased lysine and methionine levels in cooked shrimp. Regarding fatty acids (FAs), boiling, frying, and microwaving did not notably affect arachidonic acid, EPA, and DHA, although grilling caused slight alterations in their content. Lipid health indices (AI, TI, HI, HPI, NVI, and FLQI) indicate that both raw and cooked shrimp offer health-beneficial FAs and may help reduce cardiovascular diseases. Meanwhile, oxidation indices (OSA and COX) showed that the extracted shrimp fat exhibited good oxidative stability and resistance to auto-oxidation. The study also evaluated the Se:Pb molar ratio, Se-health benefit indices (Se-HBI) (Se-HBV and HBVSe), and benefit-risk value (BRV) owing to the growing link between the protective role of Se and Pb toxicity. The Se:Pb ratio and Se-HBI were > 1, highlighting the protective effect of Se against Pb exposure, whereas positive BRV values suggest that shrimp consumption provides health benefits rather than risks. The relatively higher retention of microelements observed during boiling and microwaving suggests that these methods are more suitable for cooking shrimps. This study demonstrated that Se mitigates Pb exposure by forming a Se-Pb complex, which will be considered in future risk assessments and formulation of seafood safety guidelines.</div></div>","PeriodicalId":21070,"journal":{"name":"Regional Studies in Marine Science","volume":"89 ","pages":"Article 104282"},"PeriodicalIF":2.1,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144221548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
