Accumulation of heavy metal in scalp hair of people exposed in Beijing sewage discharge channel sewage irrigation area in Tianjin, China

Based on the soil test of heavy metals in wastewater irrigation area in eastern Inner Mongolia, this paper analyses the content of heavy metals Cr, Cu, Cd, Pb in different layers of soil samples and reveals the internal relations between heavy metal concentration gradient in the vertical direction and soil properties, thus providing a scientific basis to guide sewage irrigation, solve the problem of water shortage in wastewater irrigation area and carry out environmental impact assessment. Soil is an important subsystem in natural environmental systems, through which many pollutants, especially heavy metals, produced by human activities, enter the food chain and ultimately do harm to human health. Currently, heavy metal ion contamination to the soil caused by wastewater irrigation has become one of the focuses in the study of soil chemistry and agricultural environment pollution. For this reason, it is particularly important to study the migration mechanism of heavy metals in soil and to provide a reliable theoretical basis for the prevention and management of soil contaminants.

Index Evaluation

This paper took the SongSan wastewater irrigation district of Liaoning Province, Anshan city as object of study. Base on the survey on the sewage irrigation situation, heavy metal concentration in rice grain and drinking water were measured through single pollution index evaluation and comprehensive pollution index evaluation (Nemerow index method). It could be served as the basis for environmental management and relevant laws and regulations. Experimental results showed that drinking water were not polluted by heavy mental. Sewage irrigation had a comparatively small impact on drinking water. According to the heavy mental determination results of grain crop seeds, it can conclude that the Cu and Pb content were above the national food quality standard. The pollution is serious, however, the content of Zn and Cd were below or close to the national food quality standard, which is in danger of exceeding the standard. Determined by comprehensive pollution index, it showed that the rice in the whole sewage irrigation is serious polluted by heavy mental. The heavy metal pollution presented the characteristics of extensive area-source pollution. Pollution intensity was strengthened and more difficult to be managed.
