Exposure to lead primarily affects the respiratory or gastrointestinal. Inhalation results in 30% to 70% of absorption efficiency (Ziegler, Edwards, Jensen, Mahaffey, Fomon, 1978). Absorption through the gut depends on different factors such as nutritional status and age, it also includes the increase intake of the gastrointestine that occurs in children with age younger than 6 years old. Some substances can increase lead absorption in the body, these are ascorbic acid, low dietary zinc and also citric acid while calcium, iron, alcohol, magnesium and fat can weaken the absorption of lead. (Boffetta, Nyberg, 2003). Erythrocyte can acquire almost 95% of absorbed lead in the body which impedes in the heme synthesis. Lead is distributed to soft tissues, such as brain, kidney and liver. (Barltrop, Smith, 1985).When lead is absorbed it is distributed almost to all tissues but 95% or more of the body burden is taken up in the bone which has a biological half-life of up to ten years. Lead is excreted primarily in the urine. Lead in the bone does not remain permanently but it is released slowly back in the blood circulation. (Skerving, Bergdahl,

  • Lead Toxicity in Children

    Lead is a metal found virtually everywhere even today. Sources of lead include auto body shops, electric storage batteries, glazes for china dishes, crockery, insecticides, electric cable insulation, hose, pipe, sheet and floor coverings. Lead is associated with stain glass work, jewelry making and antique ceramic doll painting. Although lead in paint was outlawed, there are still many homes that have lead paint (White et al, 1990). Lead found in gasoline was found in one study to account for 23--27% of the lead blood levels in the people tested (Wagner, 1991). This exposure to lead sources is more of a concern for children due to the characteristic habit of children to taste everything they touch; this characteristic is known as pica. Children are also in closer contact with their lead polluted environment during play. They are more active and exposed to outdoor contaminates and they inhale dust and dirt that are lead contaminated. Furthermore, the adsorption rate of lead in the digestive tract is up to 10 times greater in chil...

    When lead enters the environment, it starts to become a problem. After a period of about ten days, depending on the weather, it falls to the surface. Here lead builds up in the soil particles. Where it may make its way into underground water or drinking water due to the fact the grounds acidic or if it's soft enough. Either way it stays a long time on the soil or in water. Months or years down the road after the lead has built up it starts to become a problem for children that play outside of their homes . This lead containing soil particles get on the child's hands or clothing and end up in the child's mouth. After the build up of so much lead it leads to lead poison. Lead poisoning has been an issue since the early 1900s, when the use of lead started being banned from the manufacturing of paint in foreign countries such as Australia. Unfortunately, the United States did not start banning it until 1978, when it finally became illegal in our nation. Today 90% of the lead in the atmosphere comes from the burning of gasoline. This problem has been a large issue since the 1920s, when the Environmental Protection Agency started making laws on the amount of lead allowed in gasoline.

In their enthusiasm to recoup Depression-era losses, auto companies worked their employees harder, faster, and longer. Families spoke of young men grown old from speed-up of the assembly line. These problems were compounded by an ever-increasing disparity between the economic status of auto workers and the affluence of upper management.
