Beginning within the context of the classical risk assessment framework, this chapter discusses the origins of risks to microbiological water quality. The importance of a preventative multiple barrier approach is discussed and the advantages of controlling contamination as near to the source as possible are presented briefly. Practical, simple to use approaches are needed to identify risks and ...

A generalized model is presented to incorporate objective (hard) and subjective (soft) hazard information in automated decision-aiding systems. The model may be used with more than one hazard, of more than one type, in a given problem. Uncertainties in state measurements, dynamics, hazard extent, and hazard severity are included, as is consideration of the fact that different operators may have...

Risk assessment and HACCP are related, but fundamentally di€erent processes. Four major elements of risk assessment are commonly described (hazard identi®cation; exposure assessment; dose-response assessment or hazard characterization; and risk characterization). Some similarities exist between the inputs for the ®rst elements of risk assessment (hazard identi®cation) and HACCP (hazard analysis...

the electronics industry is one of fastest growing manufacturing industries in india. however, the increase in the sales of electronic goods and their rapid obsolescence has resulted in the large-scale generation of electronic waste, popularly known as e-waste. e-waste has become a matter of concern due to the presence of toxic and hazardous substances present in electronic goods which, if not ...

Floods are one of the most common hazards in the world, affect ing people’s lives and livelihoods. Flood hazard mapping and flood shelters suitability analysis are v ital elements in appropriate land use planning for flood-prone areas. This paper describes application of Remote Sensing (RS) and Geographical Information Systems (GIS) in identifying flood hazard zones and flood shelters and are t...
