AI summary Read the abstract

Agricultural farmlands in central Bangladesh were surveyed for microplastic contamination using microscopy and FTIR spectroscopy, detecting plastics in all 32 samples collected across four sites. Fragments and fibers were the dominant types, with contamination likely linked to irrigation water, plastic mulch use, and atmospheric deposition.

Microplastic is considered as threat to the terrestrial environment. This study analyzed microplastics contamination in four different agricultural farmlands using stereomicroscopic and spectroscopic (ATR-FTIR) analysis. Total 32 samples were collected and analyzed for microplastics contamination in farmland. About 22 MPs particles (size: 1–5 mm) have been found. 2-types of MPs (mean: 0.12 ± 0.23) were found in rural farmland, 9 MPs (0.499 ± 0.48) in sub-urban farmland, 6 MPs (0.355 ± 0.553) in urban farmland and 5 MPs (0.315 ± 0.476) in near metropolitan farmland. Fragments were the dominant microplastics than others (films, fiber, and spherules). Hence, further research is needed.

Microplastic Contamination of Non-Mulched Agricultural Soils in Bangladesh: Detection, Characterization, Source Apportionment and Probabilistic Health Risk Assessment

AI summary Read the abstract

Researchers found microplastics in agricultural soil across Bangladesh at all depths tested, even though the fields did not use plastic mulch film. Eight different plastic types were identified, with concentrations varying by location, and coastal areas had the highest levels. The study suggests that irrigation water and organic fertilizers are introducing microplastics to farmland, potentially entering the food chain through crops grown in contaminated soil.

A comparative study on the distribution behavior of microplastics through FT-IR analysis on different land uses in agricultural soils

AI summary Read the abstract

Researchers compared microplastic distribution in agricultural soils under different land uses, including soil mulching, plastic housing, and sewage sludge composting. Using FT-IR analysis, the study found that plastic particles smaller than 100 micrometers were present across all conditions, highlighting the widespread and persistent nature of microplastic contamination in agricultural environments.

Microplastics contamination in the soil from Urban Landfill site, Dhaka, Bangladesh

AI summary Read the abstract

Researchers assessed microplastic contamination in soil samples from an urban landfill site in Dhaka, Bangladesh. They found microplastics in all samples, predominantly fibers and fragments made of polyethylene and polypropylene, with concentrations varying across the landfill. The study provides some of the first evidence of terrestrial microplastic pollution in Bangladesh and identifies urban landfills as significant reservoirs of soil microplastic contamination.

Current scenario and challenges of plastic pollution in Bangladesh: a focus on farmlands and terrestrial ecosystems

AI summary Read the abstract

Researchers reviewed the sources, dispersion routes, and environmental consequences of plastic waste across global and Bangladesh-specific contexts, finding that inadequate infrastructure and limited resources make plastic pollution — including microplastics entering agricultural soils, marine environments, and food chains — an especially acute threat in developing countries.
