Buriganga River

The efforts of modern civilization to create an environment to meet human aspirations have successfully resulted in constant improvements of our lifestyle, but it has increased risks to human and ecological health. This situation has motivated many scientists throughout the world to analyze the environmental factors that can affect our health or ecology and to calculate the levels of risk. In Bangladesh development activities and utilization of the river pose a great threat to the health of the existing natural environmental system, particularly for the important river Buriganga of the capital city, Dhaka, due to the pollution of the river water. A study was carried out to observe the ecological health hazards of the Buriganga river and their risk to human health. Several random samples of water were collected from different spots on the river from September to December 2006. The samples were analyzed to determine water quality and associated environmental health risks. The study revealed that the water is high in biological oxygen demand (BOD), chemical oxygen demand (COD), phosphate (PO4 -3), ammonia, organic matters and nutrients, etc. It also revealed huge environmental health risks and possible ecological disruption of this river. Finally, the research recommends a sustainable policy framework on how the pollution could significantly be reduced by using different appropriate measures.

Reclaimed Wastewater

Health risks posed on consumers due to the use of agricultural products irrigated with reclaimed wastewater were assessed by numerical simulation. The analysis is based on defining of an Exposure Model (EM) which takes into account several parameters: (i) the quality of the applied wastewater, (ii) the irrigation method, (iii) the elapsed times between irrigation, harvest, and product consumption, and; (iv) the consumers' habits. The exposure model is used for numerical simulation of human consumers' risks by running the Monte Carlo simulation method. Although some deviations in the numerical simulation which are probably due to uncertainty (impreciseness in quality of input data) and variability due to diversity among populations reasonable results were accepted. Accordingly, there is a several orders of magnitude difference in the risk of infection between the different exposure scenarios with the same water quality. The variability indicates the need for setting risk-based criteria for wastewater reclamation, including the application method and environmental conditions, rather than single water quality guidelines. Extra data is required to decrease uncertainty in the risk assessment. Future research needs to include definite acceptable risk criteria, more accurate dose-response modeling, information regarding pathogen survival in treated wastewater, additional data related to the passage of pathogens into and in the plants during irrigation, and information referring to the consuming habits of the human community.

Bathing Water Quality

A contingent valuation (CV) study was undertaken to investigate individuals' stated willingness to pay (WTP) to reduce perceived risks of illness from the quality of bathing water at two beaches in East Anglia, United Kingdom. One beach, Great Yarmouth, failed to meet the EC (European Community) Bathing Water Quality Directive standard, whereas the other at Lowestoft passed. The analysis focuses on determinants of individuals' WTP, including measures of risk perception and attitudes to health not usually measured in CV studies. A conceptual model is then presented which sets the valuation of individual preferences in the context of personal worldviews, and external cultural, societal, and environmental factors which may influence, directly or indirectly, an individual's stated WTP.

Abstract As the core of arid Central Asia, Uzbekistan is experiencing prominent water scarcity with increasingly warming climate and accelerated human impact. To determine the hydrochemical characteristics and sources of toxic elements, as well as to assess water quality and health risks in Uzbekistan, 55 surface water samples were collected from the Amu Darya Basin of Uzbekistan (ADBU) and monitored for 20 parameters. A hierarchical cluster analysis showed that river water samples from the middle reach and Amu Darya Delta (ADD) were dominantly HCO3-Ca and SO4-Ca·Mg type, respectively. While the water samples collected near the former shoreline of the ADD and sewage outlets were dominantly Cl-Ca·Mg and Cl-Na types, which were consistent with the distribution of sites with high concentrations of toxic elements, seriously affected by human activities. Furthermore, principal component analysis indicated that the toxic elements of Pb and Cd in surface waters of the ADBU had industrial origins; local agricultural activities were considered to have contributed much of the NO3, Zn, Ni, Hg and Mn through pesticides and fertilizers; and Cu, Cr, As, and Co were controlled by mixed anthropogenic and natural sources. The results of water quality and health risk assessment also suggested that unsuitable drinking waters were displayed near the former shoreline of the ADD region and sewage outlets, and human health risks also occurred these areas.

Providing population with drinking water conforming to all hygienic standards is a pressing issue on territories where oil fields are located. In our research we focus on assessing water supply sources located in areas with oil fields and health risks for people who consume water from centralized water supply systems aimed at providing drinking water and water for communal use. Our research goal was to hygienically assess health risks for people living in areas where oil fields were located in Bashkortostan; these health risks were caused by people consuming water from centralized water supply systems. Our analysis was based on data obtained via laboratory research performed by «Bashkommunvodokanal» water supply facility and Bashkortostan Center for Hygiene and Epidemiology; the data were collected in 2016–2018 in Chishminskiy and Dablekanovskiy districts. Risks associated with drinking water quality were assessed taking into account all the requirements fixed in the Guide R 2.1.10.1920-04. Organoleptic risks related to water olfactory-reflex properties were assessed according to procedures fixed in the Methodical Guidelines MR 2.1.4.0032-11. Overall carcinogenic health risk assessed in Chishminskiy and Davlekanovskiy districts was higher than maximum permissible level due to chromium6+, DDT, lindane and arsenic detected in drinking water. Population carcinogenic risks amounted to 7 additional cases for people who consumed water supplied via water intake in Alkino-2 settlement; 69 additional cases, Isaakovskiy water intake; 76 additional cases, Kirzavodskoy water intake. Results obtained via non-carcinogenic risk assessment performed for all examined territories indicate that diseases might occur in the hormonal system (HQ =3.04–4.56), liver (HQ =2.3–3.83), and kidneys (HQ =1.47–2.45). The highest non-carcinogenic risks were detected for people who took water from Kirzavodskoy water intake in Davlekanovskiy district. We also detected unacceptable organoleptic risk (higher than 0.1) caused by excessive water hardness in Chishminskiy district. All the obtained results call for developing and implementing a set of activities aimed at reducing health risks for population.
