Compare to other documents, our study was for the first time validated the quality criteria of ICP-MS for analyzing nineteen metal levels in wastewater samples. The application of this method was then tested by analyzing nineteen metal levels in twenty-three wastewater samples in the Tham Luong Canal in Ho Chi Minh City. Based on these results, the correlation of the concentration of these metals in wastewater samples was determined.

Goldfish (Carassius auratus) may survive in aquatic environments with low oxygen partial pressures. We investigated the contribution of respiratory proteins to hypoxia tolerance inC. auratus. We determined the complete coding sequence of hemoglobinaandband myoglobin, as well as partial cDNAs from neuroglobin and cytoglobin.

A variety of organisms have been investigated to evaluate their potential as biological indicators of different forms of pollution in the aquatic environment (e.g. review by Gunkel 1994). Certain species have been identified as being highly sensitive either in their physiological response to aquatic contaminants or in their ability to accumulate particular toxins in a dose-time dependent manner.
