Unveiling the hidden impact: How biodegradable microplastics influence CO2 and CH4 emissions and Volatile Organic Compounds (VOCs) profiles in soil ecosystems
Researchers investigated how biodegradable microplastics from PBAT, PBS, and PLA affect greenhouse gas emissions and volatile organic compounds in paddy and upland soils. The study found that despite being biodegradable, these microplastics do not always promote soil emissions as expected, with PBAT and PLA actually reducing certain greenhouse gas fluxes under some conditions.

A laboratory study added three common types of microplastics — polyethylene, polypropylene, and polystyrene — to maize-soil systems at varying concentrations and measured the cascading effects on crop health and soil ecology. All types of microplastics harmed maize growth and disrupted nutrient cycling, particularly reducing phosphorus availability, though low concentrations sometimes temporarily boosted soil microbial diversity. The findings warn that microplastic buildup in agricultural soils poses a real threat to food production and ecosystem health at the scale plastics are now accumulating.
