Influence of soil properties on Ni accumulation in food crops and corresponding dietary health risk with a typical C hinese diet

Urban Farm DB summary

A large-scale survey across 515 sites and 24 crop species in Fujian Province, SE China, assessed nickel (Ni) accumulation in food crops and associated dietary health risks. Crop Ni content was influenced by both soil Ni (DTPA-extractible) and plant species, though PCA did not show strong correlations between soil-to-crop transfer factors and soil properties. The study concluded that dietary intake of foods with mean Ni content could lead to health risks, particularly for children, and that sandy soils rich in organic matter with high Ni content are unsuitable for growing rice and legumes.
