“…35 μg/dL). Also there was no significant difference in growth parameters, including weight and height, in the children of two groups [131], suggesting that the BLL was not correlated with growth parameters of children in lead mining area. In another survey, the average intelligence quotient (IQ) in 64 children living in high lead area of Zanjan province (Center of Iran) was 86.…”

Lead is an old environmental metal which is presented everywhere and lead poisoning is an important health issue in many countries in the world including Iran. It is known as a silent environmental disease which can have life-long adverse health effects. In children, the most vulnerable population, mental development of children health effects is of the greatest influence. Low level lead exposure can significantly induce motor dysfunctions and cognitive impairment in children. The sources of lead exposure vary among countries. Occupational lead exposure is an important health issue in Iran and mine workers, employees of paint factories, workers of copying centers, drivers, and tile making factories are in higher risk of lead toxicity. Moreover lead processing industry has always been a major of concern which affects surface water, drinking waters, and ground waters, even water of Caspian Sea, Persian Gulf and rivers due to increasing the number of industries in vicinity of rivers that release their waste discharges into river or sea. In addition, lead contamination of soil and air especially in vicinity of polluted and industrialized cities is another health problem in Iran. Even foods such as rice and fishes, raw milk, and vegetables which are the most common food of Iranian population are polluted to lead in some area of Iran. Adding lead to the opium is a recently health hazard in Iran that has been observed among opium addicts. There are few studies evaluated current status of lead exposure and toxicity in the Iranian children and pregnant women which should be taken into account of authorities. We recommend to identify sources, eliminate or control sources, and monitor environmental exposures and hazards to prevent lead poisoning.

“…Also, linear height growth in postnatal first 48 months of lead exposure was not statistically significant in comparison to the prenatal period (18). In the study of Mahram et al, lead exposure did not have a negative effect on height growth (27). While in the study of Sanna et al conducted in Italy, significant effect of lead exposure on height growth in 11-to 14 -year -old children in comparison with the control group was mentioned (25).…”

“…Six studies found that exposure to lead could have a negative influence on children and adolescents' height (21)(22)(23)(24)(25)(26). A study reported an association between higher blood lead levels and shorter average height, yet this result was not statistically significant in comparison to controls (27). Overall, eight to ten articles had referred to the impact of lead on short stature and two other papers did not confirm this relationship.…”

Objective: Height is a multifactorial characteristic affected by genetics, hormonal and environmental factors. The aim of this study was to systematically review the effects of environmental pollutants, chemical factors, and climate changes on children and adolescents' height.Methods: This study searched scientific databases including PubMed, ISI Web of Science, and Scopus using key words such as "Environmental Pollution", "Climate Change", "Growth", "Body Height", "Child and adolescent development", and their combination. By removing duplicates, relevant papers were selected in three phases. This review included studies that were conducted among children and adolescents up to the age of 18. After the quality assessment, data was extracted by a reviewer and rechecked by another one. The authors summarized information of 52 articles about the possible effects of environmental factors and climate change on height. Articles were divided to four categories, including air, soil, water pollutants, and climate changes.

This work is a review of the lead effects on the brain, focusing on child development. Lead can remain in the body throughout the life, being difficulty its removal, and there is no safe stable level, considering its slow passage of the bones for blood, but acceleration in moments such as pregnancy. There is evidence that the immature brain is one of the most important targets. Surveys point to later consequence in adult life, as the degenerative brain disease. In the childhood, even blood levels under 10 ?g/dL may affect cognition. Clinical studies record their toxic effects in childhood and adolescence, bringing motor, sensory, adaptive, cognitive and behavioral losses, highlighting the crime itself. It is due to the severe effects on the developing nervous system and treatment difficulties, that the priority is the population guidance on the preventive measures of exposure to lead.
