Considering the ubiquitous presence of lead in the ecosystem and the toxicity of the element even at low levels, it is of paramount importance that the environmental lead pollution and human exposure are estimated with a view for risk assessment [5,9]. 

It is evident that concern for the effects of environmental lead pollution is well considered, and it is essential for the medical and scientific communities to study further the problem of low lead toxicity and its effects.

In the midst of Patterson s ice core and Greco-Roman studies in 1965, Dr. Katharine R. Boucot asked him to submit an article about lead pollution to Archives of Environmental Health. Boucot was chief editor of the journal, considered the bible of industrial toxicology.

Scale formation in the scrubber can lead to sodium carbonate as an additional dry sorbent in the scrubber. Alternatively, limestone is also introduced into combustion chambers to treat sulfur dioxide emissions. Decomposition of CaC03 into CaO and CO2 occurs in the combustion chamber, and the resulting CaO combines with S02 to produce calcium sulfite. Notice that this process produced another potentially environmentally harmful pollutant (CO2) as it gets rid of a definite environmentally harmful pollutant (SO2). 

Lead is an acute and a chronic toxicant. Acute effects are ataxia, headache, vomiting, stupor, hallucination, tremors and convulsions. Chronic symptoms from occupational exposure include weight loss, anemia, kidney damage and memory loss. (Patnaik, P. 1999. A Comprehensive Guide to the Hazardous Properties of Chemical Substarwes, 2nbrain damage has been noted among children. Lead bioaccumulates in bones and teeth. The metal is classified as an environmental priority pollutant by the US EPA. 

The considerably higher blood Pb levels in industrial populations reflect widespread environmental Pb pollution. However, data obtained from the Second National Health and Nutrition Examination Survey (NHANES II) indicate that there has been a reduction in the overall mean blood-lead level of the U.S. population during the period 1976 through 1980 from 15.8 mg/dl to 10.0 mg/dl (Lin-Fu 1982). It is suggested that an increased use of unleaded gasoline by the U.S. population may be responsible for the observed decrease.

A study by the Association of Plastics Manufacturers in Europe (APME) assessed the environmental impacts of mechanical and feedstock recycling and energy recovery of waste plastics. It was compared in terms of consumption of resomces and environmental emission pollution potential. The criteria of consumption of energetically exploitable resources and contribution to the greenhouse effect lead to the following order of preference for feedstock recycling and energy recovery processes ... 

There is a complex relationship between environmental concerns and symptoms. There is no doubt that being exposed to an environmental hazard, such as chemicals, leads to increased fears and concerns (Bowler et al, 1994). This increase occurs whether or not the exposure is real or perceived. These fears, in turn, lead to increased symptom reporting, perhaps via activation of the stress response. The strength of a subject s opinions on environmental matters, pollution, food additives, pesticides, GM food and so on was prospectively linked to increased symptom reporting after pesticide spraying (Petrie et al, 2005). Likewise, those who described themselves as very worried about local environmental conditions were ten times more likely to complain of headaches than those not so concerned (Shusterman et al, 1991). All of...
