Determination of Soil Cadmium Safety Thresholds for Food Production in a Rice-Crayfish Coculture System

Abstract: Previous studies have mainly focused on cadmium (Cd) contamination in conventional rice monocultures, and no research on rice-crayfish coculture has been reported. In this study, a Cd-contaminated (0–30 mg kg−1) rice-crayfish co-culture system was established by adding exogenous Cd. The results showed that the Cd concentration in each tissue of rice and each organ of crayfish increased with increasing soil Cd concentration. Specifically, the Cd concentration in each rice tissue was as follows: root > stem &… Show more

“…Rapid industrialization in recent years has led to increases in the use of Cd 2+ . Cadmium-containing pollutants in the aquatic environment are becoming increasingly common, exacerbating Cd 2+ contamination of aquatic products. To regulate the market and ensure the safety of food for humans, the World Health Organization set a standard of limited detection amount of Cd 2+ in drinking water as 0.003 mg L –1 and the Chinese government has established a maximum residue limit for Cd 2+ in food (0.0001 mg L –1 for aquatic products). , However, Cd 2+ overload in aquatic products is still common. Food has been reported to be one of the major sources of Cd 2+ exposure. Cd 2+ were detected in seaweeds, crustaceans, shellfish, and cephalopods .…”
