In contrast with Mobility Factor (MF) and Risk Assessment Code (RAC) indices, IR attributes a risk share to metal species bound to reducible and oxidizable phases which are totally neglected in both of the two above-mentioned indices. In other words, besides the absolutely mobile fractions, the potentially mobile ones are also regarded in risk evaluation process elaborated by IR. The different ...

Background and Objectives: Implementation of industrial development programs, without considering environmental considerations has caused continuous entrance of pollutants to air. Therefore, the purpose of this study was assessing the ecological risk of some heavy metals in the dust of a number of non-metallic industries and determining the best indices in pollution assessment of Ardakan area. ...

1 Atmospheric metallic and arsenic pollution at an offshore drilling platform in the Bo Sea: A health risk assessment for the workers Hong Xu, Suqin Han, Xiaohui Bi, Zhijing Zhao, Lei Zhang, Wenjie Yang, Min Zhang, Jing Chen, Jianhui Wu, To investigate the ambient metal pollution at the offshore drilling platform in the Bo Sea, which few studies have focused on, PM2.5samples were collected and ...

The present investigation characterizes tannery effluents by determining water quality parameters and some selected trace metallic constituents in order to measure the magnitude of environmental pollution. Effluents and sediments have also been used to isolate chromium-resistant bacteria, collected from Hazaribagh area, Dhaka, claimed to be increasing Cr (VI)-enriched environments, and utilized...
