Background. The concentrations of heavy metals in soil and potential risks to the environment and public health are receiving increased attention in China. Objectives. The objective of this paper is to review and analyze heavy metals soil contamination in urban and agricultural areas and on a national scale in China. Methods. Initially, data on soil heavy metals concentration levels were gathered from previous studies and narratively analyzed. A further statistical analysis was performed using the geo-accumulation index (Igeo), Nemerow integrated pollution index (NIPI), mean, standard deviation (SD), skewness and kurtosis. Pollution levels were calculated and tabulated to illustrate overall spatial variations. In addition, pollution sources, remedial measures and impact of soil contamination as well as limitations are addressed. Results. The concentration level of heavy metals was above the natural background level in most areas of China. The problem was more prevalent in urban soils than agricultural soils. At the national level, the soil in most of the southern provinces and Beijing were heavily polluted. Even though the pollution condition based on Igeo was promising, the Nemerow integrated pollution level was the most worrisome. The soils in about 53% of the provinces were moderately to heavily polluted (NIPI>2). The effects were noticed in terms of both public and ecological health risks. The major sources were waste gas, wastewater, and hazardous residuals from factories and agricultural inputs such as pesticides. Efforts have been made to reduce the concentrations and health risks of heavy metals, including policy interventions, controlling contamination sources, reducing the phytoavailability of heavy metals, selecting and rearing of grain cultivars with low risk of contamination, paddy water and fertilizer management, land use changes, phytoremediation and engineering techniques. Conclusions. China is experiencing rapid economic and technological advancements. This increases the risk of heavy metals contamination of soil. If serious attention is not paid to this problem, soil toxicity and biological accumulation will continue to threaten the sustainability of China's development. Competing Interests.

Soil Metal

Few studies have been done on temporal changes of heavy metal pollution of urban soils. Eight soil samples at the same sites were collected inKaifengCity, China, in1994and 2006. Concentrations of Pb, Cd, As and Hg in the samples was measured. The pollution change of heavy metals from 1994 to 2006, and the relations between metal pollution and some human factors were discussed. The results show that soil pollution with metals in 2006 was higher than that in 1994 with economic growth. Soils in industrial district (ID) were more strongly polluted than in the following districts: (i) cultural and educational district (CED), (ii) mixed district of resident-commerce-administration (RCD), (iii) recreational district (RD), and (iv) suburban district (SD). Cd and Hg were the dominant pollutants. Economic growth, changes of land use and land-use authority can influence soil metal pollution significantly.

The statistically significant geochemical dependences of the dynamic behavior of petroleum products in urban soils in the fuel filling station zone are considered, the areal of their distribution are determined. The techniques used make it possible not only to identify laterally manmade modules of environmental hazard (laterally module) when oil products come from fuel filling stations, but also to determine additional factors of unaccounted environmental risk, for example, the process of accumulation of heavy metals in the soil profile in excess of the standards on the resulting geochemical barrier in the form of oil products. The risk assessment of oil product supply facilities should be carried out taking into account the specifics of the distribution of toxicants in technogenically altered soils.
