Research on the Relationship between Economic Growth and Heavy Metals Pollution of Lake Sediments in Nansi Lake Basin

Abstract:

The Environment Kuznets Curve (EKC) hypothesis was applied to explore the relationship between economic growth and heavy metal pollution of lake sediments in Nansi Lake basin. The indicator of economic growth (IEG) was extracted from ten important economic indexes by the method of principal component analysis based on the data from 1978 to 2007. Some representative heavy metals including Hg, Cu, Br and Mn were chosen to analyze the level of heavy metals pollution in Nansi Lake basin. According to the previous research results that the deposition rate of Nansi Lake sediments was 3.5 mm/a, Kriging interpolation method was used to segment the 10.5cm core into 30 parts. The coupling results show that there is an inverted U-shaped curve between IEG and the element Br, half of an inverted U-shaped curve between IEG and Hg and Mn, and a N-shaped curve between IEG and Cu.
