This review uses dozens of domestic and foreign literatures which were published in the last 10 years, and outlines the antibiotic problems in two different aspects below: the development of the antibiotics' analytical technology and the current situation of antibiotic pollutions in the water environment. The conclusion shows that it is still arduous and urgent to solve the problem about eliminating...
Taking the main pollution source of sewage river in north China as study object, concentrations of ammonia, chemical oxygen demand and heavy metals in sources of pollution and nearby water are determined. The two dimension steady river water quality models of ammonia and chemical oxygen demand are established, and the geometric characteristics of pollutant zone at downstream of the pollution source...
Taking the Beitang and Dagu Sewage Discharge Channels in Tianjin, China, as study objects, concentrations of heavy metals and organic matter are determined in upper layer, middle layer and lower layer sediment samples. Geo-accumulation index method and correlation analysis are taken to study the distribution and pollution level of metals between layers in the two channels contrastively. The results...
The aquatic environment is a complicated system with uncertainty. The study of uncertainty in water quality modeling can improve peoplepsilas understanding of the nature of the aquatic environment and it is important to the development of water quality modeling. The typology and sources of uncertainty is represented to improve the understanding and characterizing of the uncertainty in water quality...
