Background: The present study investigated the impact of land use on health risks (cancerous and non-cancerous) of heavy metals in soil along the Hemmat Highway of Tehran, Iran. Materials and Methods: A total of 28 soil samples were collected in August 2014 from the roadside soil of the Hemmat Highway. The collected samples were air-dried and digested, and then, analyzed for heavy metals usi...
Background: Non-biodegradation in nature and the creation of adverse health effects in humans is important features of heavy metals. The main purpose of this study was to determine the carcinogenic and non-carcinogenic risks of heavy metals As, Cd, Cu, Cr, Pb, Ni, V, and Zn in the soils of industrial areas of Mahshahr port for adults and children. Methods: To study the environmental effects of ...
Background and Objective: Non-biodegradation in nature and creation of adverse health effects in humans is important features of heavy metals. The main objective of this study was to determine the level of contamination, carcinogenic and non-carcinogenic risks of falling dust containing heavy metals on residents around the industrial areas of Ardakan. Another objective was to identify potential...
Background and purpose: The atmospheric suspended particulate matter is a major route of human exposure to different kinds of environmental pollutants especially toxic heavy metals. The aim of this study was to assess the carcinogenic and non-carcinogenic risk of cadmium in dry deposition of atmospheric dust in Qazvin, Iran. Materials and methods: Glass traps were used for sampling dry atmosp...
approach is the recognition that the response to a carcinogenic agent depends on the rate of exposure. For the radioactive agents the priority for the study of the so-called dose-rate effects appears to belong to Upton (3). A review (4) indicates that important dose-rate effects exist also for certain chemical carcinogens. Another item that I miss in Comnfield's approach is the phenomenon of sy...
