title: Assessment of arsenic (As) occurrence in arable soil and its related health risk in China.
abstract: Arsenic (As) is a major global environmental pollutant due to its high toxicity on human and animal health. This study collected 427 relevant papers to study As concentrations in Chinese arable soil and evaluate the health risk of exposure to As for humans. Results showed that the average of As concentration was 9.46 mg/kg in Chinese arable soil. Soil As concentrations in Hunan Province and Guangxi Zhuang Autonomous Region posed high carcinogenic and non-cancer risks on human health through diet, Yunnan, Guizhou, Guangdong, and Xinjiang provinces had relative high health risks, while As concentrations in the other provinces posed low health risks on humans. The physical factors controlled the spatial pattern of health risk on a provincial scale, but the As-related human activities introduced high health risk on people, particularly the agricultural activities such as sewage irrigation and fertilizer application should be given more attention due to its large area.
