Pollution Levels

An integrated pollution assessment index approach was used to assess the application of heavy metal pollution indices in the Ngoua watershed in southwestern (SW) Cameroon. The concentrations of Pb, Cr, Cu, Ni, Zn, Mo, Fe and Al in most of the water samples exceeded the maximum allowable concentration recommended by the World Health Organization (WHO). The Heavy Metal Evaluation Index (HEI) shows strong correlations with the Heavy Metal Pollution Index (HPI), Metal Index (MI) and the degree of contamination (Cd), and gives a better assessment of the pollution levels. Selected samples from the 10 sampling stations were classified as high polluted in Cd, MI and HPI in relation to the respective critical values. These values show comparable results to those of the HEI and indicate that about 88% of the samples with above average values were classified as highly contaminated and the remaining samples (12%) with below average values were classified as moderately contaminated. The Enrichment Factor (EF) analysis and the pollution indices reveal that the water quality is mainly controlled by natural and geogenic processes with major anthropogenic input. The current level of heavy metal distribution in the water of the Ngoua catchment is an environmental and health concern and requires special attention.

Based on Chinese ecological policy, we have been studying mangrove ecosystems in southern China, especially from the perspective of pollutants deposition in mangrove wetlands, physiological ecology of mangrove species on the impact of heavy metal pollution and seeking ecosystem restoration. For these, we explored in three aspects: 1) pollutants distribution and ecological risk in main distribution of mangrove, China, 2) eco-statistics and microbial analyses of mangrove ecosystems (including shellfish) in representative locations where mangrove plants are well developed, especially in Shenzhen, a rapid developing economic city in Guangdong Province, 3) ecophysiological experiments on a representative species of mangrove for evaluating combination effects of major nutrient elements and heavy metal pollution on growth and physiological responses of the seedlings. Based on the results, we proposed how to rehabilitate mangrove ecosystem in China under rapidly changing environmental conditions, with a view to our future survival and to provide nature-based solution as well as the public with more ecosystem services.
