Abstract Microplastic contamination in India has been extensively studied aquatic ecosystems, yet its implications for agricultural soils remain insufficiently addressed. This research paper bridges this gap by analyzing data from 73 studies published between 2020 and 2024, synthesizing findings on microplastic across diverse ecosystems assessing their potential impact land. While most focus microplastics beaches, rivers, lakes, ponds, only a limited number directly investigate soils, highlighting significant gap. Key sources identified include irrigation with polluted water, atmospheric deposition, industrial discharge, inadequate waste management, practices such as plastic mulch use. In Northern India, extensive networks sourcing water the Ganga, Yamuna, Sutlej rivers pose risks of infiltration into farmland. Western experiences high due to effluents, urban waste, practices. Southern Eastern coastal regions face marine estuarine pollution, potentially affecting soil crop health. Additionally, Northeastern shows threats microplastic-laden bodies deposition near lands. The review underscores urgent need standardized methodologies, comprehensive sampling, targeted pathways ecosystems. By identifying high-risk zones knowledge gaps, study provides foundation future aimed at mitigating growing threat pollution India’s sector. Addressing these challenges is crucial ensuring health, food security, environmental sustainability.

Microplastics (MP) are widespread pollutants that pose a risk to soil ecosystems globally, especially in agricultural soils. This study introduces method extract and identify MP Brazilian tropical soils, targeting debris of low-density polyethylene (LDPE) polyvinyl chloride (PVC) polymers, commonly present settings. The involves removing organic matter extracting using density separation with three flotation solutions: distilled water, NaCl, ZnCl2. Extracted then analyzed through optical microscopy Fourier transform infrared spectroscopy. removal efficiency ranged from 46% 89%, depending on the initial content soil. Recovery rates for LDPE 81.0% 98.8%, while PVC samples showed range 59.7% 75.2%. Finally, this methodology was tested four raw (i.e., without any polymer enrichment) values found were 2517.5, 2245.0, 3867.5, 1725.0 items kg−1, ferralsol, nitisol, gleysol, cambisol samples, respectively, having diverse shapes including fragments, granules, films, fibers. approach lays groundwork future studies behavior

Weathering is a significant process that alters the properties of microplastics (MPs) and consequently affects their environmental behaviors. In this study, we introduced novel approach based on polarized light scattering technique, which offers advantages in terms rapid, high-throughput, submicron-sized detection. This technique was successfully applied to characterize weathered MPs after 180-day laboratory simulation coastal environments. By employing polarization measurements, obtained 46-dimensional matrix data set for MP fragments subsequently processed them using backpropagation neural network. The successful extraction effective pulses confirmed presence within size range 0.2-60 μm, yielding total accuracies classification ranging from 78.9 86.9%. Furthermore, achieved an overall accuracy 93.8% classifying with different weathering degrees polymer types, revealing parameters associated morphological changes play dominant role characterizing MPs. Compared conventional approaches, holds great promise accurate characterization small sizes. findings study provided new insights into how change long-term aquatic
