Water quality criteria (WQC) is based on the results of scientific experiments and inferences, which prescribe a limit threshold value to pollutants and other harmful factors in water. The system of water quality criteria study is basically a blank circumstance. It's urgent to establish water quality criteria to adapt with the characters of China water environment to supply theoretic bases for revising water quality standards and managing environment. In this paper, an overview of the water quality criteria, as well as domestic and foreign research progress in theoretical methodology are systematically discussed, furthermore, considering current status of water quality criteria, comprehensive research were pointed out to be done in the future. © (2014) Trans Tech Publications, Switzerland.

Organochlorine pesticides have had a wide and long history of applications in many countries around the world, which cause serious environmental problems. Constructed wetlands are considered an effective means of removal of organochlorine pesticides. This study describes the constructed wetland and applications of organochlorine pesticides contamination in constructed wetlands, and focuses on purification for organochlorine pesticides of microorganisms and plants in constructed wetlands. Then discussed constructed wetlands removal influence factors of organochlorine pesticides. And put forward some recommendations in research. © (2014) Trans Tech Publications, Switzerland.
