Effects of Irrigation Water Sources on Soil Fertility, Heavy Metal Accumulation in both Soil and Rice (Oryza sativa L.)

Scientists found that rice grown with sewage water contains higher levels of heavy metals like cadmium, which can be harmful if eaten regularly. While this wastewater helps crops grow better by adding nutrients to soil, the toxic metals that build up in the rice could pose health risks to people who eat it. This research shows we need better monitoring of crops grown with recycled wastewater to keep our food supply safe.

Potentially toxic metals in irrigation water, soil, and vegetables and their health risks using Monte Carlo models

Researchers measured toxic metals including arsenic, cadmium, chromium, and lead in irrigation water, soil, and vegetables in Nigeria, finding levels that exceeded safety guidelines in all cases. The toxic metals accumulated in commonly eaten vegetables like spinach and cabbage, posing cancer and non-cancer health risks to adults and children. While focused on heavy metals, this research is relevant to microplastics because microplastics in agricultural soil can absorb and transport these same toxic metals into crops.
