Innovative strategies for pollution assessment in Northern Bangladesh: Mapping pollution areas and tracing metal(loid)s sources in various soil types

PLoS ONE, Год журнала: 2025, Номер 20(2), С. e0311270 - e0311270

Опубликована: Фев. 3, 2025

This study assessed the risks of soil pollution by heavy metals in Chilmari Upazila, northern Bangladesh, using static environmental resilience (Pi) model soil. Geostatistical modeling and self-organizing maps (SOM) identified areas spatial patterns, while a positive matrix factorization (PMF) revealed sources. The results showed that average concentrations Cr, Pb As were well above background levels. Agricultural industrial soils mainly contaminated with according to Nemerow Pollution Index (NPI), Ecological Risk (ER) Pi Index. Over 70% sites co-contamination was particularly high. A one-way ANOVA significant correlations between Pb, Cu Zn levels human activities. PMF analysis effluents, agrochemicals lithogenic sources main contributors contamination 16%, 41% 43%, respectively. SOM three distinct patterns (Pb-Zn, Cr-Cu-Ni Co-Mn-As), which are consistent results. These emphasize need for stringent measures reduce emissions remediate order improve quality food security.

Occurrence, source apportionment, and ecological risk of potentially toxic elements in an urban shallow lake sediment

Chemistry and Ecology, Год журнала: 2024, Номер 40(10), С. 1092 - 1113

Опубликована: Авг. 27, 2024

This study evaluated the occurrence, spatial distribution, source, and ecological risk of potentially toxic elements (PTEs) in sediment an urban shallow lake a mid-sized city. The indices, enrichment factor (EF) geoaccumulation index (Igeo) indicated high contamination with Cd moderate Ni Hg, while potential (RI) showed risk. mean contributions individual PTE species to total were following order: > Hg As Cu Pb Cr Zn. quality guideline (SQG) indices revealed that biological effects might occur occasionally due low or relatively insignificant adverse from other PTEs. There strong positive inter-metal relationships suggested their common sources. primary source responsible for elevated concentrations was traffic-related discharge. main contributors risks Ni. These findings highlight importance paying attention environment lakes, which are particularly sensitive surroundings.
