Description難降解有機污染物具有致癌、致畸和致突變效應，其生物降解是目前國際研究熱點和難點。深圳灣毗鄰深港兩地，電子工業、石化品燃燒等過程中產生的有機物在灣內大量沉積，危害生態環境和人類健康。本專案將分析其在深圳灣的遷移轉化和富集規律，開展本地微生物治理污染的理論和實踐研究，對深圳灣的生態環境改善有重要意義。Persistent organic pollutants (POPs) because of their persistence, toxicity, mutagenicity and carcinogenicity have created serious environmental problems. With recent rapid urbanization, industrialization and developments in Shenzhen and Pearl River Delta, anthropogenic pollutants such as POPs have been discharged and accumulated into our coastal environments, particularly Shenzhen Bay. These pollutants not only harmful to human health, they also pose hazardous effects to our ecosystem. Bioremediation of sediment and water contaminated with POPs has been suggested as a potential means to remove POPs from the contaminated environment. The present research attempts to analysis the contamination levels, the transport and fate of POPs in different components of the coastal ecosystem in Shenzhen Bay and their accumulation at different trophic levels. The work also aims to enrich and isolate POP-degrading bacteria from contaminated sediment and employ these microorganisms for remediation and clean-up purposes.
