The aim of this study was to compare two hot spots of lead (Pb) exposure in Israeli and Jordanian occupational settings. The study also sought to assess whether any differences in regulations and legislation regarding occupational health could be identified as a source of exposure disparities. Blood and hair specimens were collected from workers in a battery factory in Jordan and a secondary Pb smelter in Israel and compared. About 33% of the currently exposed group showed blood lead (BPb) levels above the internationally recommended concentration of 40 µg dL?1. Although the differences of BPb levels between Israel and Jordan were not statistically significant, average levels were lower in Jordan. Beyond the difference in the factory types, disparity in exposure levels might be explained due to a combination of proclivities of factory management, public policies, existing medical surveillance and insurance, as well as cultural differences. Results reveal that despite existing regulations and the growing attention that is dedicated to Pb and metal occupational exposures, there are still hot spots for Pb exposure in Israel and Jordan. The contrasting experience found in the current study raises the possibility that information and technology exchange between the two countries Israel and Jordan, may be beneficial for improving occupational health policy in these two neighboring countries. 相似文献

The basin scale has been promoted universally as the optimal management unit that allows for the internalization of all external
effects caused by multiple water uses. However, the basin scale has been put forward largely on the basis of experience in
temperate zones. Hence whether the basin scale is the best scale for management in other settings remains questionable. To
address these questions this paper analyzes the economic viability and the political feasibility of alternative management
options in the Kidron/Wadi Nar region. The Kidron/Wadi Nar is a small basin in which wastewater from eastern Jerusalem flows
through the desert to the Dead Sea. Various options for managing these wastewater flows were analyzed ex ante on the basis
of both a cost benefit and a multi-criteria analysis. The paper finds that due to economies of scale, a pure basin approach
is not desirable from a physical and economic perspective. Furthermore, in terms of political feasibility, it seems that the
option which prompts the fewest objections from influential stakeholder groups in the two entities under the current asymmetrical
political setting is not a basin solution either, but a two plant solution based on an outsourcing arrangement. These findings
imply that the river basin management approach can not be considered the best management approach for the arid transboundary
case at hand, and hence is not unequivocally universally applicable. 相似文献

This paper examines whether the relationships between a number of characteristic limnological variables (suspended particulate matter, turbidity, Secchi depth, light attenuation, and chlorophyll a) determined for temperate lakes are consistent with the relationships found in Mediterranean lakes such as Lake Kinneret. We found that the use of published relationships between lake variables may lead to erroneous results when applied indiscriminately to other lake types. 相似文献
