Microplastics in manure: Sources, analytical methods, toxicodynamic, and toxicokinetic endpoints in livestock and poultry

Environmental Advances, Journal Year: 2023, Volume and Issue: 12, P. 100372 - 100372

Microplastics are pollutants of serious environmental and public health concern. Although predominantly known to occur in biological matrices, emerging scientific evidence has indicated that they can also fecal matter. Animal manure, both raw treated, is usually applied on farmlands as organic fertilizer, serving an entry point microplastic particles into agricultural soil. The present study analyzes the literature occurrence microplastics (sources analytical methods detection livestock poultry manure), their toxicodynamic, toxicokinetics endpoints farm animals. Based studies examined herein, there a lack harmonization sampling, digestion, extraction procedures for animal manure. abundance was 9.02 × 102 ± 1.29 103 particles/kg-1 pig, 7.40 101 cow, 0 5000 particles/kg−1 sheep, 129.8 82.3 particles/g−1 (0.1298 particles/kg) chicken have been found manure were primarily ingested from microplastics-contaminated feed plastic mulching film attached crop residues. However, other likely sources (e.g., water, soil, air) need be studied carefully. Despite limited fate weight currently available shows exhibit different characteristics during treatment previous all based composting experiments. Therefore, research required profound sense better understanding influence physicochemical properties (shape, size, type, composition) treatment. Moreover, exposure animals revealed several toxicological effects but more needed clearly understand dose-response relationship, absorption, distribution, metabolism, elimination mechanisms with respect factors (microplastic sizes, shapes, polymers, types additive, co-contaminants).

Prediction of future microplastic accumulation in agricultural soils

Environmental Pollution, Journal Year: 2024, Volume and Issue: 359, P. 124587 - 124587

Published: July 20, 2024

This study shows the general exponential rise in microplastic accumulation agricultural soils, with fertilizer application speeding up this increase, and future predictions of concentrations. Utilizing data from Broadbalk winter wheat experiment at Rothamsted Research, UK, 1846 to 2022, Poisson regression models were applied counts under different soil treatments, including farmyard manure, inorganic fertilizers, control conditions. A mass conversion factor was obtain w/w relationship. Results indicated a significant annual increase concentrations across all fertilized soils showing notably higher rate. Our forecasts that, 50 100 years now, treated fertilizers are expected reach 168.9 mg kg−1 (95% CI: 60.32–473.09) 1159 200.49–6699.8) respectively, levels converging on those used many experiments. highlights urgent need for strategies mitigate pollution fields. The results also help choose predicted global change experiments, as well motivate further research explore mechanisms integration these insights into broader ecological guide sustainable practices environmental conservation.

Exposure assessment of plastics, phthalate plasticizers and their transformation products in diverse bio-based fertilizers

The Science of The Total Environment, Journal Year: 2024, Volume and Issue: 918, P. 170501 - 170501

Published: Feb. 2, 2024

Bio-based fertilizers (BBFs) produced from organic waste have the potential to reduce societal dependence on limited and energy-intensive mineral fertilizers. BBFs, thereby, contribute a circular economy for However, BBFs can contain plastic fragments hazardous additives such as phthalate plasticizers, constituting risk agricultural soils environment. This study assesses exposure associated with phthalates in three types of wastes: food industry (AgriFoodInduWaste), sewage sludge (SewSludge), biowaste (i.e., garden, park, kitchen waste). The wastes were various treatments like drying, anaerobic digestion, vermicomposting. number microplastics (0.045–5 mm) increased AgriFoodInduWaste-BBFs (15–258 particles g−1), SewSludge-BBFs (59–1456 g−1) then Biowaste-BBFs (828–2912 g−1). mostly contained packaging plastics (e.g., polyethylene terephthalate), mass (>10 g kg−1) exceeding EU threshold (3 kg−1, >2 mm). Other small (< 1 non-packaging copolymers) amounts below limit. calculated numbers entering via BBF application was high (107–1010 ha−1y−1), but released <7 kg ha−1y−1) compared (95–156 ha−1y−1). concentrations di(2-ethylhexyl)phthalate (DEHP; < 2.5 mg transformation products 8 low benchmark 50 kg−1 DEHP), attributable impact current phase-out DEHP well degradation during treatment. Biowaste-BBF exposed vermicomposting indicated that worms accumulated (4 kg−1). These results are overall positive implementation studied SewSludge-BBFs. safe use requires reducing improving sorting methods minimize contamination environmental impact.
