“…The resulting quality of the atmosphere has been the subject of various publications [4][5][6] , especially with reference to the health impacts of different toxic metals [7][8][9][10][11] . Several studies have also incorporated the role of size and composition of atmospheric particulate matter towards overall heavy metal toxicity [12][13][14][15] .…”

The concentration of lead, iron and potassium were determined in suspended particulates matters (SPM) in the atmosphere Dhaka, Bangladesh between January and June, 2008. The sampling areas are Khandakar Mukarram Hossain Biggan Bhaban, University of Dhaka, Tejgaon, Hazaribagh, Uttara and Agargaon new colony. The average concentrations of TSP, PM10 and PM2.5 were 68, 43 and 35 µg m-3, respectively. About 82% particles were from fine fraction (PM2.5) and 18% were from coarse fraction (PM10-2.5), which indicates mechanical processes are one of the main sources for the particulate matters in air of Dhaka. The concentration of lead, iron and potassium were determined by using atomic absorption spectrophotometer (AAS) for the size fraction of PM10 with highest concentrations recorded for iron (10.8 g/m3) and lowest for lead (0.10 g/m3). The average concentration of NOx, O3 and SOx with eight hours sampling were 82.8, 22.5 and 25.5 g/m3 respectively. This study revealed that the concentrations of Pb, K, Fe, CO, NOx, O3 and SOx in Dhaka City were higher than the WHO (World Health Organization) guideline values.

Daily intakes of metals in drinking water are of extreme importance in risk assessment to human health. Some papers focused on this topic, but most of them did not consider the effect of age, gender and work location on daily intakes of metals in drinking water. The objective of present paper is to estimate the levels of Cu, Zn and As ingestion in drinking water in Shanghai, China and the effect of age, gender and work location on daily intakes of these metals. It was also the first time that such a detailed investigation on daily intakes of metals in drinking water was carried out in China in recent years. Drink/Sample (D/S) method was used to estimate the daily intakes of Cu, Zn and As in drinking water. The mean concentrations of Cu, Zn and As in drinking water were 10.8 Ag/l, 0.29 mg/l and 0.91 Ag/l, which were lower than U.S. EPA's Drinking Water Equivalent Level (DWEL) and WHO guideline values. The average daily intakes of Cu, Zn and As in drinking water was 21.12 Ag/d, 0.65 mg/d, and 1.83 Ag/d, which were on average 0.01%, 1.1% and 1.5% of the provisional maximum tolerable daily intake (PMTDI) set by the Joint FAO/ WHO Expert Committee. There was a significant difference in daily intake of Zn for different work locations ( P = 0.04). But no other significant differences in daily intakes of metals in drinking water were found according to age, gender and work location. D

Chemical residues which could contaminants cow milk are chlorinated pesticides, organophosphates, herbicides, fungicides, antihelminthetic drugs, antibiotic, hormones, detergents and disinfectants, nitrites, poly chlorinated, poly brominated biphenyles, dioxins, mycotoxins, heavy metals and somatotropin hormone. Antibiotics such as betalactams, tetracycline, amino glycosides (e.g. streptomycin, neomycin and gentamycin), macrolides (e.g. erythromycin) and sulfonamides are the source of residues. Because of the public health significance, milk and milk products contaminated with antibiotics beyond a given residue levels, considered unfit for human consumption. Problems associated with antibiotic residues in milk include the risk of allergic reactions and occurrence of antibioticresistant bacteria, teratogenicity risk to the foetus, hypoplasia in developing teeth, aplasia of bone marrow, chronic insidious intake lead to elevated cancer risk and disruption of body's reproductive, immune, endocrine and nervous system. Organochlorine pesticides are substances containing contaminants classes: The dichlorodiphenylethanes, the chlorinated cyclodienes (aldrin, dieldrin, heptachlor, etc.), and the hexachlorocyclohexanes (lindane). The most common effects of the wide spread of organochlorine compounds in the environment are birth defects, neurological effects, behavioral effects, reproductive effects and cancer. The occurrence of chemical residues in the milk of lactating cows is a matter of public health concern, since dairy products are widely consumed by infants, children and many adults throughout the world. Governments have responsibility for making regulations to protect consumers against harm arising from chemical in food. The regulation of illegal residues in foods is a cooperative effort of Food Safety and Inspection Services, Feed and Drug Administration and Environmental Protection Agency. However, inEthiopia not yet attention given regarding to set standards, control measures and monitoring program of chemical residues in animal originated foodstuff.
