Ecological Risk Assessment Of Heavy Metals In Sediments Of A Riverine Wetland, Huaihe River Watershed, China

Abstract

The concentrations of Zn, Cr, Cu, As, Cd, and Pb in sediment cores collected from a representative riverine wetland located in the Huaihe River watershed, China, dramaticlly increased from the bottom to upper layer of the cores. Application of principal component analysis (PCA) and enrichment factor (EF) suggested that heavy metals might primarily have been derived from the inflow of contaminated water from an industrial park and agricultural region. Component 1 of the PCA was dominated by Zn, Cr, Cu, Cd, and Pb, while Component 2 was dominated by As. Metals’ high concentrations and EF values showed that the anthropogenic pollutants have increased sharply in recent years and reflect the continuous development of industry and agriculture in the region of the wetland, with a corresponding dramatic deterioration of the environment due to constant effluent of pollutants. Cd exerted the highest potential ecological risk of individual metals of sediment cores. Additionally, integrated RI values for all metals indicated that sediments possessed low ecological risk from the bottom to about 6 cm depth of the cores, moderate ecological risk from about 5 cm depth upwards, then considerable ecological risk from 4 cm depth to the top layer of the sediment cores, which demonstrates a continuous deterioration of environmental quality in recent years in this region.

Measurement and analysis of ammonia emission from a pig farm in the northeast of China

Abstract

China is the largest swine production country in the world. The fast development has consequently brought various environmental issues which have already seriously threatened the environmental quality. This study is aimed to measure the concentrations of NH3 in the pig houses in the selected pig farm, try to conclude characteristics on the concentration change and the correlation between the concentrations and the environmental factors. The NH3 concentration was monitored in two fattening pig houses. The concentrations fluctuated between 11.0 and 26.9 ppm, 11.0 and 28.5 ppm respectively during the measurement periods, peaking at the early morning and in the afternoon before cleaning. The concentrations of NH3 correlated to the indoor temperature in winter, whereas, there was no correlation between relative humidity and NH3 concentrations.
