Exposure to lead remains a major environmental matter around the world as measures to deal efficiently with this problem in both developed and developing countries have been heightened.

Doubts that lead exposure has weighty health significances at levels below those considered medically acceptable decades ago are held by a few while the debate over what levels of lead exposure in the contemporary world, if present, can be considered as of nominal harm is still evident. The exposure to and the uptake of this element has consequently increased. However, in most of the developed nations, the introduction of lead into the human environment has reduced over the years, mainly due its commercial usage, particularly in petrol and also due to public health campaigns.

Even though severe lead poisoning has become infrequent in such countries, chronic exposure to lower levels of the element still remains a public health issue. This is particularly among some socioeconomically disadvantaged groups and other minorities. In developing nations, sentience of the impact of exposure to lead to public health is rising but very few of these nations have formulated policies that would combat this problem.

Lead is a highly toxic substance, exposure to which can produce a wide range of adverse health effects. Both adults and children can suffer from the effects of lead poisoning, but childhood lead poisoning is much more frequent, Pocock SJ, Smith M, Baghurst PA. Over the past years through which we have learnt of the hazards of lead, millions of children have undergone its health effects.

Presently also, , an estimated , children who are under the age of six have too much lead in their blood, Centers for Disease Control and Prevention There are many recognized ways through which human beings may be exposed to lead. This could be through: waning paint, bare soil, house dust, air, food, drinking water, porcelains, hair dyes and other cosmetics. Children with elevated blood lead levels, more often, are exposed to lead in their own home. Lead, an ever-present and nifty metal, has been on the use ever since prehistoric days.

It has become extensively spread and accumulated in the environment. Human exposure to and uptake of this non-essential element has consequently increased. Damage to almost all organs of the human body is evident at higher levels of exposure. Some of the organs affected are exemplified by: the kidneys and blood, the central nervous system, which can further lead to death in excessive levels. Most researches that have been carried out in the past 30 years have shown adverse health effects of abstemiously increased blood lead levels, i.

The allowable exposure levels in the ambient air, water, soil, etc. Furthermore, exposures through occupation or the environment has remained a serious problem in many developing and industrializing countries, Centers for Disease Control and Prevention This review focuses on lead poisoning in children because of the high prevalence of lead in the environment, and because the impact of lead exposure on children's neurocognitive development, in particular, is substantial.

Emerging data suggest a health impact on neurocognitive function at much lower blood concentrations of lead than thought earlier. Childhood lead remains a major public health problem for certain groups of children, specifically African-American children in the USA, children living in areas of low socioeconomic status, children living in rural mining communities, and children in developing countries such as India and the Philippines, Zietz B, de Vergara JD, Kevekordes S, Dunkelberg H.

This paper also presents a case study of the assessment of children exposed to lead in different areas of the world such as Esperance, Western Australia, America among others to illustrate the principles of managing such events from a public health perspective, as well as the scientific rationale for this approach. Exposure was first reported in BC.

It was most common among industrial workers in the 19th and early 20th centuries. This was due to their exposure through plumbing, painting, smelting, printing and a host of other industrial activities, Pocock et al Tanqueral des Planches, in , defined the symptoms of acute lead poisoning. His study was so detailed that little has been added to the clinical signs and symptoms of acute lead poisoning in adults. At around midth century in the United Kingdom, lead poisoning through occupation was a common condition. However, in , after the deaths of several employees working in the lead industry, a legislative enquiry was instigated to look into the working conditions in lead factories.

This resulted in the Factory and Workshop Act Prevention of Lead Poisoning , which required lead factories to conform to certain minimum standards, e.

In Australia, lead poisoning in children was first reported in , although it was not until 12 years later that the source, peeling lead-based paint, was identified in a series of ten children with lead colic. In a follow-up study of 20 schoolchildren in the USA who had experienced acute lead poisoning in infancy or early childhood found that exposure to environmental lead at levels insufficient to produce clinical encephalopathy was associated with long-term deficits in neuropsychological development, Centers for Disease Control and Prevention Studies of Case-control on hyperactivity and mental retardation in relation to environmental lead exposure revealed that children who lived through acute intoxication of lead were every so often left with severe insufficiencies in neurobehavioral function.

The exposure of environmental lead to human populations was comparatively low before the industrial revolution but has however heightened with large-scale mining and industrialization. Globally, the extensive processing of lead ores is estimated to have released about million tones of lead into the environment over the past five millennia, mostly within the past years. Following the introduction of automobiles at the beginning of the 20th century, environmental lead has substantially been on the increase due to the use of leaded fuel.

Lead Lead emitted by vehicles continues even today and presents a health risk to the population. Much of emitted lead remains in soil where it was dumped over the years, mainly in frequented roads and highways. Pets can as well come into contact with lead-contaminated soil hence lead to human exposure when in contact with the pet.

In each such case, an elevated blood lead level can easily result, Zietz Bet al More recently identified sources of lead exposure for children include industrial environmental sources, such as the shipping of lead in the case of Esperance. Newly identified sources of lead poisoning over the last 10 years also include fishing weights, otherwise known as sinkers, snooker chalk, and lead paint found on products including children's toys and barbeques.

flatterteno.tk Increasing globalization has a marked impact on risk as, for example, in the case of lead paint on toys made in China appearing in shops in the USA and Australia. As a result, there is an increasing need for public health authorities to be vigilant for both domestic and imported lead hazards and to put surveillance systems in place for early identification of such hazards, Pocock et al The most recent US death associated with lead toxicity was in a child who swallowed metal jewelry, Centers for Disease Control and Prevention This 'imported risk' may affect certain ethic groups more than others.

For example, significant amounts of lead are found as a contaminant or an intentional adulterant in some herbs and ethnic remedies including ayurvedic herbal products, imported spices, or Hispanic folk remedies such as 'litargirio'. However, toys made with lead paint are distributed more widely than these remedies. The best way to assess the degree of lead poisoning in children is by taking venous blood for lead estimation.
