Analysis of Environmental and Biota Samples for Assessment of Persistent Toxic Substances

This project is aimed at studying the toxic effects of different environmental contaminants in sewage effluent discharged from two sewage treatment plants to Mai Po RAMSAR site, the most important biological conservation site in South China. I. Analysis of environmental (sewage/river water/pond water/sediment) and biota (fish/shrimp) samples for assessment of persistent toxic substances (Heavy Metals (HMs) and Metalloid; Polycyclic Aromatic Hydrocarbons (PAHs); Polybrominated Diphenyl Ethers (PBDEs); Dichlorodiphenyltrichloroethane (DDTs); and Erythromycin). II. Analysis of physical characteristics of environmental (sewage/river water/pond water/sediment) and biota (fish/shrimp) samples (Total Suspended Solids (TSS); Volatile Suspended Solids (VSS); Total Solids (TS%); Volatile Solids (VS%); pH; Chemical Oxygen Demand (COD); 5-Day Biochemical Oxygen Demand (BOD5) (with nitrifier inhibitor); Lipid contents of biota.
