Identifikasi Kelimpahan Dan Karakteristik Fisik Mikroplastik Pada Air Irigasi Sawah Sekitar TPA
AI summary Read the abstract
This study identified and characterized microplastics in irrigation water from rice fields in Indonesia, documenting the types, sizes, and abundance of MP particles entering agricultural systems through irrigation water and highlighting potential risks to food safety.
Microplastics have now become one of the most prominent environmental pollutants, particularly due to their impact on aquatic ecosystems and irrigated rice fields. This study aims to identify the abundance and physical characteristics of microplastics in irrigation water from rice fields surrounding the Final Waste Disposal Jalupang, Karawang. Water samples were collected from seven irrigation points using a purposive sampling method and analyzed under a binocular microscope. The results showed the highest microplastic concentration occurred at the primary irrigation inlet, reaching 536.50 particles/L. The predominant shape was fragments, with the majority of particles measuring less than 1.00 mm in size. In terms of color, black and transparent microplastics were the most prevalent, indicating advanced degradation due to prolonged exposure to open environmental conditions. The distribution pattern of microplastics was strongly influenced by the existing condition of the irrigation channels, agricultural activities, and the hydraulic residence time within the paddies. The findings of this study are consistent with previous research indicating that the primary source of microplastics in agricultural land originates from the breakdown of household and agricultural plastic waste, undergoing photodegradation and physical weathering. This study highlights the urgent need for improved plastic waste management and the implementation of sustainable irrigation systems to mitigate microplastic accumulation in agricultural soils.

Quantification and Identification of Microplastics in Irrigation Water Systems: Ecological Risks and Mitigation Strategies
AI summary Read the abstract
A survey of seven sites in a rural irrigation network found microplastic concentrations up to 64.3 particles per liter, with contamination levels strongly correlated with nearby population density and dominated by PET, PP, and PS fibers and films. Because irrigation water directly contacts food crops, widespread microplastic contamination in agricultural water systems represents a significant and underappreciated pathway for human dietary exposure.
Unravelling the emerging threats of microplastics to agroecosystems
AI summary Read the abstract
This review synthesizes evidence that microplastics accumulate in agricultural soils from multiple pathways, disrupting soil physical and chemical properties, shifting rhizosphere microbial communities, and potentially entering plants through water and nutrient uptake channels. Because most microplastic research has focused on aquatic systems, the effects of soil MP contamination on crop yield, food quality, and long-term agricultural sustainability remain critically underexplored.

This Indonesian study identified microplastic abundance and physical characteristics (shape, color, size) in paddy field soils near the Jalupang final waste processing site in Karawang Regency, finding 266–746 microplastic particles per kilogram of sediment with fibers and fragments predominating.
Hazards of Microplastic Pollution in Agriculture
AI summary Read the abstract
This review examined the sources and hazards of microplastic pollution in agricultural settings, including plastic mulch degradation, sewage sludge application, and plastic packaging, and their effects on soil health and crop systems. Agricultural microplastic exposure is especially significant for human health because it creates a direct farm-to-table contamination pathway, with particles and leached chemicals potentially present in vegetables, grains, and livestock products.
