Contamination of microplastics in soil and water environments has become a matter concern globally. To explore the existence agricultural soils, this study was carried out different systems with distinct agronomic practices farm inputs. A simple cost-effective digestion-density separation method adapted to digest, extract, segregate from quantify occurrence microplastics. The pretreatment Fenton reagent saturated sodium chloride further addition 30% H2O2 at 60±2°C reduced organic 81%. After reducing interference, were quantified. With microfibres as most predominantly found microplastic shape, mean abundance observed follows: treated sewage irrigated field (1650±0.00 items kg-1) > paddy (1500±0.71 integrated farming system (1250±2.12 inorganic fertilizers applied (1025±4.60 manures (1000±0.71 plastic mulched (800±5.66 kg-1). per cent concentration blue (37.71±3.10), black (29.41±1.75), pink (23.87±1.62) commonly identified colors ascendancy while polyethylene dominating among sorted confirmed through PCA. This reveals that possible sources are likely inputs used farmlands atmospheric deposition studied lands. Such observations systematic emphasize need implement sustainable protect quality promote public health. is first its kind work Agricultural Soils India, which offers significant insights into present status pollution soils within Coimbatore area Tamil Nadu, India. These findings can potentially guide policy decisions aimed environmental health hazards linked contamination initial stages.

Microplastics (MPs) are small plastic pieces less than 5 mm in size. Previous studies have focused on the sources, transports, and fates of MPs marine or sediment environments. However, limited attention has been given to role land as primary source MPs, how polymers transformed into through biological abiotic effects during transport process remains unclear. Here, we focus exploration main sources soil, highlighting that MP generation is not solely a byproduct production but can also result from impact factors transport. This review presents new perspective understanding degradation considering soil distinct fluid suggesting transformation change mediated by occur surface, while biodegradation occurs interior. viewpoint suggested because some becomes obvious interior, whose surface expected colonize microorganisms, gradually considered carbon independent photosynthesis net production. emphasizes need understand basic information for rational evaluation its environmental toxicity. Such enables better control pollution affected areas prevents contamination unaffected regions. Finally, knowledge gaps future research directions necessary advancements this field provided.

Nanoplastics (NPs) have different colors, which could affect their photoaging processes in aquatic environments. This study investigated the effects of irradiation on physicochemical properties and aggregation kinetics five colored NPs. Photodegradation rates photooxidation degrees ranked white ≈ yellow > red blue black NPs, indicating that NPs with longer color wavelengths photoaged faster. The discoloration process followed fading (2-14 days, except for NPs), yellowing (10-16 days), (18 turning transparent (20-22 days). White exhibited a sequence (C-H → C-OH C═O O-C═O) from others. was mainly controlled by singlet oxygen, producing 13 chemicals were mostly organic acids. overall colloidal stability pristine white. Irradiation 16 days retarded other NaCl solution, raising critical coagulation concentration (CCC) 82.14 0.85-7.90%, respectively. Contrarily, promoted CaCl2 solution reducing CCC (67.37%) (33.33-37.58%) findings demonstrate underwent white/transparent focused previous work, highlighting important role environmental fate transport.

This comprehensive review critically assesses traditional and emerging technologies for domestic wastewater treatment reuse, focusing on the transition from conventional centralised systems to innovative decentralised approaches. Through an extensive literature search serving a population equivalent of less than or equal 10, study juxtaposes linear circular methods highlights their impact urban water management environment. The papers reviewed were classified into five categories: Environmental studies, economic social technological reviews policy papers. analysis was carried out separately approaches within each category. In addition, maturity technology (lab/pilot full-scale application) taken account in analysis. research landscape is shown be evolving towards that promise sustainability through resource recovery, despite dominance perspectives. lack clear progress technologies, scarcity circularity assessments challenges integration are highlighted. Operational reliability, regulatory compliance support identified as key barriers adoption systems. While pollutants environmental impacts well addressed systems, its infancy. Conclusions these hazardous tentative cautious. Social studies mainly based virtual scenarios, which useful tools achieving goals. conceptual frameworks assessing dimension need further refinement effective. paper argues balanced centralisation decentralisation, proposing dual strategy emphasizes development interoperable technologies.
