A simple numerical experiment to evaluate the influence of model resolution on estimates of ambient air quality and associated human exposure is presented. This is done based on annual mean NO2 concentration fields for the agglomeration of Brussels and su... see more

The vitamin D3-weighted UV exposure of a human with vertical posture was calculated for urban locations to investigate the impact of orientation and obstructions on the exposure. Human exposure was calculated by using the 3D geometry of a human and integr... see more

Several approaches have been used to assess potential human exposure to environmental stresses and achieve optimal results under various conditions, such as for example, for different scales, groups of people, or points in time. A thorough literature revi... see more

Heavy metals in surface and groundwater were analysed and their sources were identified using multivariate statistical tools for two towns in South Africa. Human exposure risk through the drinking water pathway was also assessed. Electrical conductivity v... see more

 Plumbum enters through various environmental factors such as inhaled air, digestion, urine as much as 75-80%, feces 15%, and others such as sweat, hair, and nails. The impact of exposure to lead can affect erythrocyte index. The erythrocyte index is... see more

AbstractBackground: Healthcare facilities in South Africa are confronted by several challenges arising from Human immunodeficiency virus (HIV) and acquired immune diseases syndrome infection pandemic. All categories of nurses continue to experience accide... see more

Seven different arrays of points for spatial averaging of the RF field strengths in the frequency range from 100 MHz to 3 GHz were investigated by numerical simulations in a 2D planar environment under several multipath propagation conditions in connectio... see more

The aim of the paper is to investigate effects of long term x-ray exposure on the human lymphocyte, reactive lymphocyte parameters and morphology of lymphocytes in x-ray technicians at Kirkuk hospitals. The study included 54 apparently healthy male x-ray ... see more

Abstract: The impact of pesticide residues on human health is a worldwide problem, as human exposure to pesticides can occur through ingestion, inhalation, and dermal contact. Regulatory jurisdictions have promulgated the standard values for pesticides in... see more
