“…Recent studies show that many urban children have high blood Pb levels due to exposure of soil-borne Pb (figure 1). Small children are more susceptible to increased levels of Pb intake due to frequent hand-to-mouth behaviour (Mielke 1999) after playing in an environment with hazards such as elevated levels of Pb in house dust or yard soils (Bellinger 2004, Choi et al 2005.…”

“…24 We have observed laser-induced incandescence in our system when a 532 nm Nd:YAG laser at a similar fluence replaced the 193 nm source, and a plasma was observed when 193 nm light was used to ablate or fragment a solid surface containing lead. 25 The signal from 193 nm photons scattered from the particles is too small to use as a quantitative measure of particle disintegration. In addition, the scattered signal is not easily interpreted; changes in the signal are difficult to ascribe to changes in morphology or particle size and mass.…”

“…An increasing number of studies report suitable signs of lead-induced neurological and/or behavioral effects in children starting at about 10 ug/dL or less, in the range of 30-40 ug/dL the population effects being clearer, [2]. The claims by some researchers with special interests that neurobehavioral performance is effected by lead, and the effects are longlasting and may not have a threshold value especially heme synthesis, and fetal development, [4].…”

“…The injury depending on age, socioeconomic status, the population of a given community and race, [1]. Long-term exposure to the lead may contribute to elevated blood Pb levels, especially in young children, who are more susceptible to elevated Pb concentrations in dust and soil because of their repetition of hand-to-mouth and pica behavior, [2]. The negative health effects associated with the element include the development of inhibited brain and hematological effects, like anemia [3], due to Pb that accumulating in the kidney, liver, teeth and bones, [4,5].…”
