Today's ecology is erected with miscellaneous framework. However, numerous sources deteriorate it, such as urban rivers that directly cause the environmental pollution. For chemical pollution abatement from urban water bodies, many techniques were introduced to rehabilitate the water quality of these water bodies. In this research, Bacterial Technology (BT) was applied to urban rivers escalatin...

Introduction: Dental units are among the equipment that flows through the dental application, and due to the durability of water and the probability of forming the biofilm. They can have a high microbial load. It is important to investigate this pollution, which should be frequently investigated due to the incidence of dangerous infections in people with weakness of the defense system, pollutio...

Improper land use is one major cause of non-point source pollution. Integrated modeling would support the evaluation and optimization of land use for the non-point source pollution control. In this study, the CLUE-S (the Conversion of Land Use and its Effect at Small regional extent) and SWAT (Soil and Water Assessment Tool) models were coupled to simulate pollution loads under different land u...

~sing of the environment, the electroplating industry is likely to be one of the industries to be affected by the introduction of the water pollution control legislation in Hong Kong. The effect may be even more pronounced for the operators of small and medium-sized electroplating factories since they are unlikely to have any expertise in pollution control and will therefore require outside tec...

Health education is an important component of efforts to control schistosomiasis. In China, while education programmes have been implemented intensively, few articles in recent years in either the Chinese or English literature report randomised, controlled interventions of the impacts on knowledge, attitudes and behaviours. Thus, we designed and carried out a cluster-randomised controlled educa...

For the last 20-odd years in China, an economic boom has resulted in severe environmental pollution; water pollution, particularly, is of great concern. It has been reported that pollution in China’s overall surface water is rated medium. The water quality of groundwater, lakes and reservoirs has deteriorated. Consequently, such a general distribution of water pollution has posed a grave threat...

Process safety and environment pollution demands are continuously increasing in the process industry. Apart from that, requirements regarding final product quality and production efficiency are higher and higher [1]. This can be achieved by applying advanced process monitoring and control techniques. Process control is heavily dependent on the quality of the data, so it is crucial to measure as...
