Abstract
Objectives: Heavy metal pollution has become a serious health concern in recent years. Cadmium (Cd) and Lead (Pb) are toxic heavy metals. This study was aimed to determine the risk factors for high cadmium and lead levels in school children. Design and methods: The scalp hair samples were obtained from 760 children at 13 schools in Istanbul. A questionnaire was prepared to gather information about demographic and socioeconomic characteristics of the children. Hair cadmium and lead concentrations were determined by atomic absorption spectrophotometer. Results: Household exposure to smoking and attending a school near to Main Streets were found to be the most important risk factors for the high hair cadmium and lead levels in our study. Conclusion: These findings support the public health recommendations that children should not have household exposure to smoking, schools should not be near to the main streets and unleaded gasoline use should be promoted.

Cadmium (Cd) contents were determined in 30 brands of tobacco cigarette commonly available in Nigeria by atomic absorption spectrophotometry. The concentration of Cd in the cigarettes ranged from 0.7 to 2.3 g/g dry weight with mean 1.48 ± 0.46 g/g. Higher Cd concentrations were found in imported brands (1.52 ± 0.46 g/g) compared to the Nigerian brands (1.10 ± 0.35 g/g). Relatively lower Cd values were observed in cigarettes from developing countries (~ 1.3 g/g) compared to brands from devel...

Cadmium is a cumulative nephrotoxicant that is absorbed into the body from dietary sources and cigarette smoking. The levels of Cd in organs such as liver and kidney cortex increase with age because of the lack of an active biochemical process for its elimination coupled with renal reabsorption. Recent research has provided evidence linking Cd-related kidney dysfunction and decreases in bone mineral density in nonoccupationally exposed populations who showed no signs of nutritional deficiency. T...

To evaluate the significance of cadmium (Cd) concentrations in blood (B-Cd) and hair (H-Cd) as an indicator of dose, a cross-sectional study was performed on 40 residents in a Cd-polluted area, Nagasaki Prefecture, Japan, in 1996. In the study area, soil replacement of Cd-polluted rice fields ended in 1981. B-Cd and H-Cd were significantly higher in the study population than in the control subjects. B-Cd was positively correlated with urinary Cd (U-Cd) (Spearman r=0.50, P=0.06 for males and r=0....

Determination of inseparable exogenous and endogenous levels of toxic trace elements such as lead in human scalp hair has been used to understand and assess population exposure to such elements. For any such analysis, washing of the hair samples to remove superficial contamination is the foremost requirement. However, the use of such washing methods prior to elemental analysis removes minute quantities of trace elements from the hair strands. This degree of loss is dependent on the washing metho...

Abstract Lead and cadmium concentration was determined in the hair of 327 school children living in a wastewater spreading field of Marrakesh (Morocco). The influence of age, sex, food habits and family occupation on the children's hair Pb and Cd concentration was also evaluated. Girls had more metal in their hair than boys (16.5±5.4 μg/g and 12.5±3.5 μg/g, respectively). However, for Cd the boys had more metal (2.9±0.6 and 2.2±0.4, respectively) but the difference was not statistically signific...

Abstract Background Initial interest in the adverse consequences of exposure to lead (Pb), mercury (Hg), and cadmium (Cd) focused on relatively high exposures through environmental or occupational sources; however, recent evidence suggests even low-level background exposure to non-essential metals might be detrimental, particularly for children's health and development. One potentially important source of increased background levels of non-essential toxic metals is diet. Objectives We considered...

Abstract We investigated the effects of the gestational administration of lead (Pb) and ascorbic acid on cerebellar development. Pregnant female rats were randomly assigned to the control, Pb, or Pb plus ascorbic acid (PA) groups; six offspring per cage were randomly selected for analysis. Compared to the control group, fewer Purkinje cells were observed in the Pb-exposed pups at postnatal day 21. However, co-administrating Pb and ascorbic acid inhibited the Pb-induced reduction in Purkinje cell...

Tobacco smoke contains various toxic heavy metals that individuals are exposed to when they smoke. Despite the presence of heavy metals in tobacco smoke, the relationship between smoking and the accumulation of toxic metals in pregnant women after long-term exposure remains under discussion. We examined the association between long-term exposure to tobacco smoke and the accumulation of toxic metals in the hair of female participants. Our study recruited 252 women from the Shanxi and Hebei provin...

Human biomonitoring can be a reliable tool to protect the health of the citizens of major urban environments. Human hair may be an invaluable specimen to determine chronic exposure to any environmental contaminant in an individual, especially in the young population. However, different factors including a lack of studies that have established reference values for metals and metalloids (trace elements) in human scalp hair make the use of this matrix controversial. A monitoring study was performed...

Monitoring the levels of trace elements in hair can allow estimating the effects of the geographical location and also can provide a notion of the metal body burden. However, the use of human hair is controversial due to the different confounding factors that could affect the presence of trace elements in hair. As a result, a comprehensive monitoring study was performed in Alcala de Henares, one of the major cities in the Madrid region, Spain. Trace elements have been monitored in urban topsoils...
