Abundance and Distribution of MPs and NPs in Soil: A Global Scenario
AI summary Read the abstract
Researchers reviewed the global distribution of microplastics and nanoplastics in agricultural soils and terrestrial environments, finding that these particles are far more widespread on land than previously appreciated and pose a silent but growing threat to soil health and the food we grow.
The worldwide abundance of microplastics (MP) and nanoplastics (NP) is generally identified as a persistent problem to the marine environment and is already deemed a silent threat in aquatic environments. However, their presence in agricultural soil and terrestrial...

Soil Pollution by Micro- and Nanoplastics: Sources, Fate, and Impact
AI summary Read the abstract
Researchers examine how micro- and nanoplastics enter soil systems, persist through environmental processes, and threaten soil fertility and ecosystem health, with direct implications for agricultural productivity, food security, and human health.
Soil Pollution by Micro- and Nanoplastics: An Overview
AI summary Read the abstract
"This overview synthesized evidence showing that annual plastic releases to terrestrial environments are 4 to 23 times higher than releases to the ocean, with microplastics entering soil via sewage sludge, compost, plastic mulch, and irrigation. Soil contamination at this scale threatens agricultural food safety and groundwater quality, creating direct pathways for microplastics and associated toxins to enter the human diet through crops and drinking water."
Navigating The Hidden Crisis: Microplastics And Heavy Metals in Soil- Transport, Impact, and Remediation
AI summary Read the abstract
Tiny plastic bits in soil don't just sit there, this review of existing research shows they can team up with toxic heavy metals already in the ground, making those metals up to 30-50% more likely to leach out and get absorbed by crops. That matters because it means the food grown in contaminated soil could carry more heavy metal contamination than previously thought, though scientists still need more real-world data to fully understand the risk to people who eat those crops.
