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

Journal of Hazardous Materials, Journal Year: 2022, Volume and Issue: 441, P. 129959 - 129959

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.

Potential sources and occurrence of macro-plastics and microplastics pollution in farmland soils: A typical case of China

Critical Reviews in Environmental Science and Technology, Journal Year: 2023, Volume and Issue: 54(7), P. 533 - 556

Published: Sept. 23, 2023

AbstractPlastic debris (including macro-plastics, microplastics (MPs), and nanoplastics), defined as an emerging contaminant, has been proven to significantly affect soil ecosystem functioning. Accordingly, there is urgent need robustly quantify the pollution situation potential sources of plastics in soils. China leading producer user agricultural analyzed a typical case study highlight current farmland macro-plastics MPs. Our summarized information on occurrence abundance MPs Chinese soils for first time based 163 publications with 728 sample sites. The results showed that average concentration farmlands were 103 kg ha−1 4537 items kg−1 (dry soil), respectively. In addition, this synthesized latest scientific evidence Agricultural plastic films organic wastes are most reported sources, indicating they contribute Furthermore, modeling methods quantifying estimating stock flow materials within systems also summarized.Keywords: Abundancefarmland soilsmacro-plasticsmicroplasticsquantitative methodsource apportionmentHANDLING EDITORS: Hyunjung Kim Jörg Rinklebe Disclosure statementThe authors report no competing interests declare.Additional informationFundingThis research was supported by National Natural Science Foundation under Grant [number 42277097]; UKRI Global Challenges Research Fund (GCRF) Environment Council project, "Do undermine food security sustainable development less economically developed countries?"

Polymers Use as Mulch Films in Agriculture—A Review of History, Problems and Current Trends

Polymers, Journal Year: 2022, Volume and Issue: 14(23), P. 5062 - 5062

Published: Nov. 22, 2022

The application of mulch films for preserving soil moisture and preventing weed growth has been a part agricultural practice decades. Different materials have used as films, but polyethylene plastic considered most effective due to its excellent mechanical strength, low cost ability act barrier sunlight water. However, use carries risk pollution health hazards, hence new laws passed replace it completely with other over the next few years. Research find out about biodegradable polymers this purpose gained impetus in past years, driven by regulations United Nations Organization’s Sustainable Development Goals. primary requisite these is biodegradability under natural climatic conditions without production any toxic residual compounds. Therefore, developed from fossil fuels, microorganisms, animals plants are viable options using mulching material. solution not simple since each polymer different properties compromise be made terms film. This review discusses history materials, gradual evolution choice process biodegradation regarding material used, types that can explored potential future prospects area.

Plastic–Rock Complexes as Hotspots for Microplastic Generation

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(17), P. 7009 - 7017

Published: April 3, 2023

Discarded plastics and microplastics (MPs) in the environment are considered emerging contaminants indicators of Anthropocene epoch. This study reports discovery a new type plastic material environment─plastic-rock complexes─formed when debris irreversibly sorbs onto parent rock after historical flooding events. These complexes consist low-density polyethylene (LDPE) or polypropylene (PP) films stuck quartz-dominated mineral matrices. plastic-rock serve as hotspots for MP generation, evidenced by laboratory wet-dry cycling tests. Over 1.03 × 108 1.28 items·m-2 MPs were generated zero-order mode from LDPE- PP-rock complexes, respectively, following 10 cycles. The speed generation was 4-5 orders magnitude higher than that landfills, 2-3 seawater, >1 order marine sediment compared with previously reported data. Results this investigation provide strong direct evidence anthropogenic waste entering geological cycles inducing potential ecological risks may be exacerbated climate change conditions such Future research should evaluate phenomenon regarding ecosystem fluxes, fate, transport impacts pollution.
