Plastic products are widely used around the world, but waste plastic is not reasonably managed and causes serious pollution. Biodegradable plastics (BPs) provide an alternative to conventional plastics, all BPs can be completely degraded under natural conditions. Instead, they may break down into microplastics (MPs) faster than posing additional threat soil environment. In this paper, definition, applications, degradation behaviors of BPs, including biodegradable (BMPs), reviewed, we comprehensively summarized eco-toxicological effects BMPs in ecosystems, terms physical chemical properties soil, nutrient cycling, bacterial fungal communities, flora fauna. The compound other pollutants were also addressed. results revealed that made different or more severely compared MPs. Overall, review aims address gaps knowledge, shed light on ecological soil. a perfect substitute solve pollution, further exploration should focus their generation, environmental behavior, impact whether cause harm

Bioplastic (PHBV) addition to soil alters microbial community structure and negatively affects plant-microbial metabolic functioning in maize

Microplastic contamination poses a significant threat to agroecosystem functioning, provoking move away from the use of conventional oil-based plastics in agriculture, biodegradable alternatives that may be degraded over shorter timescale. The impact these bioplastics on plant and soil health, however, has received relatively little attention. Here, we investigated effect loading (0.01%, 0.1%, 1% 10%) biobased microplastic poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) (Zea mays L.) health function. We showed PHBV caused dose-dependent reduction growth foliar nitrogen (N) content while untargeted metabolite analysis revealed shifts metabolic These results were also reflected soil, where led reduced availability both ammonium nitrate. Soil 14C-isotope tracing 16S metabarcoding suppressed microbial activity, bacterial diversity shifted community structure, inducing major shift pathways, thus functioning. Overall, our data suggests bioplastic is not environmentally benign levels as low 0.01% (0.01 mg kg-1) can induce short-term changes with potential implications for long term health.
