Summary

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.
