Health Risk Assessment of Arsenic in Soils of School Playgrounds and Residential Areas, Central China

Abstract:

Soil samples were collected from school playgrounds and residential areas of children in Hubei Province, China. Total arsenic content in 2 partial fractions (0-0.25mm and 0-2mm) of soil samples were analyzed. The average total arsenic content of samples in 0-0.25 fraction were 8.43 and 9.43 mg kg^-1 in rural and urban soils, respectively, while in the 0-2mm fraction, the average arsenic content were 9.09 and 11.64 mgkg^-1. Risk assessment for children in these study sites implied that hazard quotient of arsenic with the reason of soil ingestion were below 1, and the carcinogenic risk was acceptable (<1.0×10⁻⁶) in all the sample sites. There was significant difference between the risk assessment with the total arsenic value in 0-0.25mm and 0-2mm fractions in urban soils. While in soil samples of rural areas, risk assessment of different soil fractions had similar results.
