AbstractRiver Hooghly, a tributary of river Ganges is one of the major rivers of Asia having traditional, social, economic, religious, and spiritual values. Water samples were collected from 18 sampling locations of river Hooghly during summer (dry), monsoon (wet), and winter (cold) seasons. The samples are analysed for basic physicochemical properties and abundance of selected potentially toxic elements (PTEs) are measured. Several PTEs, e.g., Al, Fe, Ni, and Pb, were found to be above the permissible limits, prescribed by national and international guidelines for safe human consumption. The trend of variation in the mean PTE concentrations showed the following order: Cd < Pb < Co < Cr < Ni < Cu < Zn < Mn < Fe. Due to the presence of high total dissolve solid (TDS) and PTE contents, the water quality of river Hooghly is not suitable for direct human consumption. The evaluated Water Quality Index (WQI) value showed a distinct spatio-temporal variation indicating very severe condition of water quality, which is deteriorating gradually from upstream to downstream. In summer, monsoon, and winter, the highest WQI values were observed in Maushuni Island (S15), Petuaghat (S18), and Tapoban (S17), respectively. However, the non-carcinogenic human health risk in terms of Hazard Quotient and Hazard Index values of PTEs indicates no immediate adverse impact on human health due to exposure of PTE contaminated water from river Hooghly through ingestion or dermal route. Though, these risk values for children were higher than adults warranting the adoption of a long-term management plan to cope with potential human health risks. The result suggests implementation of a combination of stringent socio-legal regulations and numerical models for sustainable water related health risk management in river Hooghly.

Abstract River Hooghly, an offshoot of river Ganges is one of the major rivers of Asia having traditional, social, economic, religious and spiritual values. Water samples were collected from eighteen sampling locations of river Hooghly during summer, monsoon, and winter season, and analysed for basic physico-chemical properties and selected potentially toxic elements (PTEs). Several PTEs such as Al, Fe, Ni and Pb were above the permissible limits, prescribed by national and international guidelines. The trend of variation in the mean PTE concentrations showed the following order: Cd < Pb < Co < Cr < Ni < Cu < Zn < Mn < Fe. Due to the presence of high total dissolve solid (TDS) and PTE contents, the water quality of river Hooghly is not suitable for direct human consumption. The evaluated Water Quality Index (WQI) value showed a distinct spatio-temporal variation indicating very severe condition of water quality, which is deteriorating gradually from upstream to downstream. In summer, monsoon and winter, the highest WQI values were observed in Maushuni Island (S15), Petuaghat (S18) and Tapoban (S17) respectively. However, the non-carcinogenic human health risk in terms of Hazard Quotient and Hazard Index values of PTEs indicates no immediate adverse impact on human health due to exposure of PTE contaminated water from river Hooghly through ingestion or dermal route. Though these risk values for children were higher than adults warranting the adoption of a long-term management plan to cope with potential human health risks. The result suggests implementation of a combination of stringent socio-legal regulations and software based models for sustainable water related health risk management in river Hooghly.

Treatment Plant

On 16 October 1996, a malfunction at the Swan Hills Special Waste Treatment Center (SHSWTC) in Alberta, Canada, released an undetermined quantity of persistent organic pollutants to the atmosphere. An ecologically based, staged health risk assessment was conducted to evaluate the human health risk, the findings of which are presented in Part 2, on Ecotoxicology and Human Health Risk. The incident resulted in the largest fine for an environmental infraction in Alberta history up to that time. Despite the incident, the province of Alberta has continued to subsidize the facility and has kept it in operation, with changes in management. The policy rationale is that if the facility were not available, accumulation and possible diversion of hazardous waste into illegal disposal alternatives would threaten the environment much more than operation of the plant. This case study illustrates an ecological approach to risk assessment and an attempted culturally sensitive approach to risk management. Incidents in which people are exposed to toxic substances do not occur in a social vacuum. Risk management strategies must be adapted to groups with different cultural values and expectations. Community and individual responses to such incidents, and the development of health advisory messages, may depend on presenting information on exposure and risk in terms consistent with cultural patterns among subpopulations in the community.

Health Risk Management

Health risk evaluation, as subjected to many environmental factors (chemical, physical, lifestyle, etc.), is a topical scientific and practical task, because human is never exposed to a single factor, and human health risk management requires consideration of maximal possible amount of environmental and factorial influences. The article deals with methodological approaches to multifactor risk evaluation and contains the results of pilot project on mortality risk assessment, exemplified by population of the Kirovograd city district of Sverdlovsk region, considering smoking and multifactor exposure to noise and chemical pollution of air. The authors presented assessment of economic losses due to the exposure and suggestions of methodological approaches development and elaboration of techniques for multifactor risk assessment to improve municipal system of health risk management and provide sanitary and epidemiological safety.
