achieving effective environmental policy making and environmental protection. Its particular focus is on toxic substances and chemical hazards. It asserts that the community is a major stakeholder in respect of environmental policy, and it argues that access to information is an essential prerequisite for effective community input into environmental decision-making. More specifically, informati...

Over the past three decades, a formal risk assessment process has been developed to provide consistent and transparent methods for the assessment of potential human health risks from exposure to environmental chemicals. Given a focus on risk to human health, epidemiological studies that identify associations between exposure to environmental chemicals and adverse health effects in humans have t...

fault tree analysis (fta) as a probabilistic risk assessment (pra) method is used to identify basic causes leading to an undesired event, to represent logical relation of these basic causes in leading to the event, and finally to calculate the probability of occurrence of this event. to conduct a quantitative fta, one needs a fault tree along with failure data of the basic events (bes). someti...

environmental effects associated with pesticide application have motivated the development of integrated pest management programs throughout the world. advantages of the implementation of such a program like food security, biodiversity, consumer and producer security can be stated as economic value. estimating the economic value of such programs can be helpful in identifying the benefits as wel...

Hydrometallurgical facilities processing sulfide based ores produce waste residues in the form of sludges that contain concentrations of metals, as well as metal sulfides. As a part of the waste characterization and risk assessment process, a statistical design of experiment was used to assess the significant factors and interactions in the residue leaching process. Two shake flask experiments,...

fractionation studies on the sediment samples provide valuable information on the nature of the metals bound to the sediments. thirty three sediment samples of river adyar were collected during two seasons and speciation study was carried out. the industrial and domestic effluents are directed into the river course at many points in the middle and lower of the adyar river. to ascertain the exte...

conclusions overall, the results derived from these studies indicated that hospital safety levels in most of the surveyed hospitals were moderate. although the situation in hospitals is not critical, there is a need to plan and take appropriate measures to improve the safety level of the hospitals. results hospital preparedness in disaster was evaluated in three dimensions: structural, non-stru...

the safety of hydrogen generation facilities is the main concern in their process operation. this study was conducted to identify the hazards and evaluate the risks of a hydrogen generation plant. for this purpose, prha (process hazard analysis) was applied for hazard identification while lopa (layer of protection analysis) was used for risk assessment. the study was conducted in the hydrogen p...
