Dataset for: Fe oxides control the vulnerability of paddy soils to microplastic-induced carbon loss
AI summary Read the abstract
This study found that iron compounds in rice paddy soil help protect against carbon loss when tiny plastic particles (microplastics) are present. When these iron compounds are lacking, microplastics can cause more carbon to escape from the soil as CO2 gas. This matters because healthy soil carbon storage is important for growing nutritious food and fighting climate change, but microplastics from pollution could be disrupting this natural process.
This dataset contains the original data used in this study, including basic physical and chemical properties of the soil, CO2 emissions, 13C-NMR, and qPCR quantitative data.

Dataset for: Fe oxides control the vulnerability of paddy soils to microplastic-induced carbon loss
AI summary Read the abstract
This research found that iron compounds in rice paddy soil help protect against carbon loss when tiny plastic particles (microplastics) are present. When these iron compounds are low, microplastics cause more soil carbon to escape as CO2 gas, which could worsen climate change. This matters because microplastics are increasingly common in agricultural soils from plastic pollution, and healthy soils are crucial for growing food and storing carbon.
Data supporting "Polyethylene microplastics reorganize carbon–iron coupling and mineral-associated carbon in lateritic soils"
AI summary Read the abstract
Scientists studied how plastic pollution affects soil in India, finding that microplastics change the way carbon and iron interact underground, disrupting how soil normally locks away carbon. This matters because healthy soil helps grow our food and store carbon that would otherwise contribute to climate change, so plastic waste breaking down in farmland could have ripple effects on both agriculture and the environment.
Data supporting "Polyethylene microplastics reorganize carbon–iron coupling and mineral-associated carbon in lateritic soils"
AI summary Read the abstract
Scientists studied how plastic pollution affects soil that many tropical regions rely on for farming. They found that microplastics change how carbon binds to iron minerals in soil, which could affect how much carbon stays locked away versus released. This matters because healthy soil carbon storage supports fertile farmland and helps regulate climate, both tied to food security and long-term human wellbeing.
Dynamic production of hydroxy radicals affects the available Cadmium in paddy soils under microplastic contamination
AI summary Read the abstract
Researchers showed that polyethylene microplastics amplify hydroxyl radical production in flooded paddy soils through photochemical activation of plastic-derived dissolved organic carbon and iron cycling, raising plant-available cadmium concentrations by up to 4.5-fold and highlighting a previously overlooked mechanism by which microplastics worsen heavy metal contamination in rice fields.
Susceptibility of Cd availability in microplastics contaminated paddy soil: Influence of ferric minerals and sulfate reduction
AI summary Read the abstract
When microplastics and cadmium contaminate paddy soil together — a common situation in agricultural areas — microplastics increase the availability of cadmium to plants, raising the risk of cadmium uptake into food crops like rice. The mechanism involves microplastics releasing dissolved organic matter that disrupts iron mineral cycling and promotes sulfate-reducing bacteria, which in turn mobilize cadmium from soil particles. These findings highlight that microplastic pollution in farmland does not act alone — it can amplify the toxicity of co-occurring heavy metal contaminants.
