Risk assessment of potentially toxic element pollution in soils and rice (Oryza sativa) in a typical area of the Yangtze River Delta
309
TL;DR: The risk assessment of PTEs through rice consumption suggests that the concentrations of Cu, Pb, and Cd in some rice samples exceed their reference oral dose for adults and children.

The Challenges and Solutions for Cadmium-contaminated Rice in China: A Critical Review.
Yuanan Hu,Hefa Cheng,Shu Tao +2 more
TL;DR: To eliminate the long-term risk of Cd entering the food chain, soils contaminated by Cd should be cleaned up when cost-effective remediation measures are available.

TL;DR: While rice plant tissues' Cd content was significantly reduced, depending on biochar application rate, reduction in plant Pb concentration was found only in root tissue, and analysis of the fresh and contaminatedBiochar particles indicated that Cd and Pb had probably been bonded with the mineral phases of Al, Fe and P on and around and inside the contaminated biochar particle.

Heavy metal pollution and health risk assessment of agricultural soils in a typical peri-urban area in southeast China.
TL;DR: The integrated method of ecological and health risk index, which takes consideration of both anthropogenic emission and cropping system can provide a practical tool for evaluating of agricultural soil in the peri-urban area regrading different risk factors.

Multivariate and geostatistical analyses of the spatial distribution and origin of heavy metals in the agricultural soils in Shunyi, Beijing, China.
TL;DR: Multivariate and geostatistical analyses suggested that soil contamination of Cd, Cu and Zn was mainly derived from agricultural practices, whereas, As and Pb were due mainly to soil parent materials, and Hg was caused by the atmospheric deposits from Beijing City.

TL;DR: In Shizhuyuan area, China, the total THQ values of adults and children through consumption of vegetables were 4.12 and 5.41, respectively, suggesting that the residents may be facing health risks due to vegetable consumption, and that children were vulnerable to the adverse effects of heavy metal ingestion.

Development of a DTPA soil test for zinc, iron, manganese and copper
Willard L. Lindsay,W. A. Norvell +1 more
TL;DR: A DTPA soil test was developed to identify near-neutral and calcareous soils with insufficient available Zn, Fe, Mn, or Cu for maximum yields of crops.

Health risks of heavy metals in contaminated soils and food crops irrigated with wastewater in Beijing, China
TL;DR: It is highlighted that both adults and children consuming food crops grown in wastewater-irrigated soils ingest significant amount of the metals studied, however, health risk index values of less than 1 indicate a relative absence of health risks associated with the ingestion of contaminated vegetables.

Health risks of heavy metals to the general public in Tianjin, China via consumption of vegetables and fish.
TL;DR: Consumption of vegetables and fish contaminated with the heavy metals Cu, Zn, Pb, Cd, Hg, and Cr is the most likely route for human exposure in Tianjin, China and health risks associated with these heavy metals were assessed.

Assessing risk of heavy metals from consuming food grown on sewage irrigated soils and food chain transfer.
TL;DR: Partitioning pattern of soil revealed high levels of Zn, Cr, and Cu associated with labile fractions, making them more mobile and plant available, and human risk was found to be high for Zn followed by Cr and Pb with special reference to leafy vegetables particularly spinach and amaranthus.

Transfer of metals from soil to vegetables in an area near a smelter in Nanning, China
TL;DR: Results showed that both soils and vegetables from villages 1 and 2 were heavily contaminated, compared to a village 50 km from the smelter, and oral intake of Cd and Pb through vegetables poses high health risk to local residents.
