widespread use of pharmaceuticals has resulted in mixture concentrations ranging from mg/l in effluent to µg/l concentrations in surface water. in a 2008 study, 13 pharmaceuticals, ranging in amounts from 0.0028 to 0.1757 µg/l, were identified in the tennessee river, usa and its tributaries. in order to address the need for risk assessment of environmentally relevant pharmaceutical mixtures, da...

the territory of serbia is vulnerable to various types of natural hazards and the risk is not equal across the entire territory; it varies depending on the type of hazard and the expected potential for damage. the first aim of this research was to determine the geographical distributions of the major types of natural hazards. seismic hazards, landslides, rock falls, floods, torrential floods...

background: tea is the most popular nonalcoholic beverage worldwide. in recent years, some iranian studies have shown the occurrence of toxic elements in fresh or dried tealeaves as well as in brewed tea. the present study aimed to ascertain the health risks associated with exposure to toxic and essential element through black tea consumption in iran by systematically reviewing the accredited a...

This research presents the geotechnical zoning map of district 1 in Shiraz municipality with focus on municipal deep excavation hazard assessment on data from 160 boreholes. For this purpose, the mechanical properties are determined according to the results of direct shear, uniaxial, and SPT tests and then excavation hazard assessment with depths of 3, 6 and 9 m, in situations where the excavat...

NIST Handbook 146, HAZARD I—Fire Hazard Assessment Method [1], represents the culmination of a long-term program aimed at placing the prediction of fire outcomes on an objective and scientific basis. In the 1970s, NIST supported Harvard University to develop numerical models that could predict the temperature in a room containing a fire. These early models were difficult to use and interpret; r...

Abstract Hazard maps are essential tools to aid decision makers in land-use planning, sustainable infrastructure development, and emergency preparedness. Despite the availability of historical data, there has been no attempt produce hazard for Kuwait. In cooperation with World Bank, this study investigated natural anthropogenic hazards that affect The objective was assess face Kuwait map most c...

an erosion hazard index methodology (ehim) was developed for assessing stream erosion. the index of stream erosion is designed as a management tool. assessing stream erosion involves consideration of a range of aspects of streams and a value judgment about a desirable state. the assessment of the erosion indicators of streams was based on a state-wide assessment of physical stream condition. a ...

drilling industry provides a significant potential for occupational health risks. thus, health-related hazards (chemical, physical, ergonomic and biological) must be recognized, evaluated and controlled in order to prevent occupational illnesses which come from exposure to them. for these, a good occupational health risk assessment needs to be applied. risk assessment monitors risks and provide...
