Abstract
A systematic investigation was carried out to analyze the concentration levels of heavy metals in the sample seawater, sediments and biota collected from the coastal area of Yancheng City of Jiangsu Province of China. An assessment was carried out on the impact of these heavy metals in different environmental samples in terms of potential risks to ecology and also to the human population exposed to this area. Additionally, a further investigation was carried out on selected samples which were considered to pose higher level of potential risks to ecology or human health, to test their toxicity to zebrafish (Danio rerio) at early-life stage. Chemical analysis showed relatively higher concentrations of heavy metals in the seawater and biota samples collected from Xiangshui County and Binhai County. The heavy metal concentrations in different samples collected from the close vicinity of Dafeng Port were also comparable. Considering all the seawater and sediment samples, heavy metals showed a relatively moderate level of risk to ecological species; for consumption of marine organisms, heavy metals had adverse impacts on the human health. Toxicity assessment indicated the selected environmental samples or their extracts showed significant toxicity to zebrafish early-life stage, such as lethality, teratogenicity, and hatching delay (or advance). So, this current investigation provides very useful and important information on the heavy metals pollution in Jiangsu Province.
