Increasing salinity is one of the most significant and widespread forms of groundwater pollution in coastal areas. This paper
presents the causes and impacts of saline water intrusion in coastal areas. Various causes of salt water intrusion, and approaches
for the determination of its extent and various measures to control the salt water intrusion are described. An aquifer performance
test (APT) approach is presented to identify the extent of existing salt water intrusion in the study area located in the
southwest coastal region of Gujarat State (India). A resistivity based experimental technique is used to identify the quality
of the groundwater available at different depths. A methodology is presented to assess the extent of available fresh and saline
groundwater and to find out the limit up to which lower saline groundwater can be withdrawn for industrial purposes without
affecting the upper fresh water layer which can be made available for domestic purposes. 相似文献

Purpose. In lower-middle-income countries, most of the work is performed manually using non-ergonomic hand tools which results in work-related health problems. Using hand tools designed in line with ergonomic principles may play an important role in reducing work-related health concerns significantly. Methods. Scientific databases (PubMed, EBSCOhost) and e-publishers were searched for articles from 1985 to 2015 using the following keywords: ‘hand tool’, ‘ergonomics’, ‘usability’ and ‘design’. After applying selection criteria to 614 articles, 58 articles related to the physical design of hand tools were selected. Results. Seventeen articles were related to hand tool improvement in the manufacturing sector. Musculoskeletal disorders were found to be the most frequently occurring work-related health problems. Most of the articles focused on product and qualitative variables for improvement in hand tools, while few articles considered human and task variables. Conclusions. Literature shows that hand tool improvement studies have been given less importance in low-income and lower-middle-income countries. However, some work of significance is reported in the agriculture sectors of these countries. Hence, it is concluded that ergonomic intervention in hand tools is much needed for those industries which employ traditional methods of working. 相似文献

Assessment of daily intake of trace elements by Kakrapar adult population through ingestion pathway 总被引:1,自引:0,他引:1

Concentration of trace elements such as Fe, Cu, Ni, and Zn were measured in cereals, pulses, vegetables, fish, meat, milk, egg, and water samples collected around Kakrapar, Gujarat, India. A wide variation of the trace element concentration was observed among all the dietary matrices. The concentration of Fe is comparatively more in all the dietary matrices. The concentrations of these elements are translated into intake rates through ingestion pathways. Daily intake (milligrams/day) of Fe, Cu, Ni, and Zn by adult population of Kakrapar, Gujarat were 16.5 ± 6.2, 3.3 ± 1.2, 1.8 ± 1.0, and 3.6 ± 1.3, respectively. Dietary sources of Fe, Cu, and Ni by Kakrapar adult population are comparable with RDA. In case of Zn, the daily dietary intake is comparatively lower than that of RDA. 相似文献

This study evaluates the health risks in megacities in terms of mortality and morbidity due to air pollution. A new spreadsheet model, Risk of Mortality/Morbidity due to Air Pollution (Ri-MAP), is used to estimate the excess numbers of deaths and illnesses. By adopting the World Health Organization (WHO) guideline concentrations for the air pollutants SO2, NO2 and total suspended particles (TSP), concentration-response relationships and a population attributable-risk proportion concept are employed. Results suggest that some megacities like Los Angeles, New York, Osaka Kobe, Sao Paulo and Tokyo have very low excess cases in total mortality from these pollutants. In contrast, the approximate numbers of cases is highest in Karachi (15,000/yr) characterized by a very high concentration of total TSP (~670 μg m?3). Dhaka (7000/yr), Beijing (5500/yr), Karachi (5200/yr), Cairo (5000/yr) and Delhi (3500/yr) rank highest with cardiovascular mortality. The morbidity (hospital admissions) due to Chronic Obstructive Pulmonary Disease (COPD) follows the tendency of cardiovascular mortality. Dhaka and Karachi lead the rankings, having about 2100/yr excess cases, while Osaka-Kobe (~20/yr) and Sao Paulo (~50/yr) are at the low end of all megacities considered. Since air pollution is increasing in many megacities, and our database of measured pollutants is limited to the period up to 2000 and does not include all relevant components (e.g. O3), these numbers should be interpreted as lower limits. South Asian megacities most urgently need improvement of air quality to prevent excess mortality and morbidity due to exceptionally high levels of air pollution. The risk estimates obtained from Ri-MAP present a realistic baseline evaluation for the consequences of ambient air pollution in comparison to simple air quality indices, and can be expanded and improved in parallel with the development of air pollution monitoring networks. 相似文献

Data from National Health and Nutrition Examination Survey were used to evaluate the impact of pregnancy on the levels of triclosan (TCS) in urine. Regression models were fitted to evaluate this association with adjustment for other factors that may affect the levels of TCS. Pregnant females had higher levels of TCS than non-pregnant females but the differences were not statistically significant. Levels of TCS were statistically significantly lower during the second trimester than during the third trimester. Smoking was associated with statistically significantly lower levels of TCS. The reasons for the association between smoking and the levels of TCS are not known. Further research is needed in this area. 相似文献

In today’s world of stricter drinking water disinfection standards there is a search for disinfection solutions that abide by the new standards while keeping the disinfection operation cost-efficient and safe. Ozone disinfection has the potential not only to meet but also to exceed the limits. Along with disinfection, the use of ozone for drinking water treatment can also have many other benefits such as taste and color removal, iron and manganese removal, and insecticide removal. p]Ozone disinfection has been used widely in Europe for well over a century, but many of its great benefits are just now being realized in the United States. Ozone disinfection has been the focus of many recent studies in the drinking water field. p]The purpose of the research for this paper was to analyze ozone disinfection from technology transfer and related policy perspectives. This paper reports the aspects used to analyze the technology as well as the results. A modified version of the Strategic Technology Evaluation Program was used to evaluate ozone disinfection’s transfer viability. p]This study has demonstrated that ozone disinfection, to be fully accepted into the drinking water industry, must first be accepted by the American Water Works Association, a nationally recognized professional and trade organization. Once this acceptance is gained, individual municipalities will more readily accept the technology. p]Another driving force that will likely bring about the adoption of ozone disinfection of drinking water would be stricter drinking water disinfection standards that can be best met by this technology. 相似文献
