“…The levels from the control areas were comparable with or even higher than those published in previous studies on urban populations (Rodushkin and Axelsson, 2000;Chojnacka et al, 2005). Some subjects in TZ on the other hand, showed extremely high levels of Cu and Pb, with the 95th percentile estimate at 143 and 251 mg/g, respectively.…”

“…Lead was further moderately correlated with Cd (r ¼ 0.56, p < 0.05) but had no correlation with Cu in the control areas, giving further evidence for e-waste related exposure of Pb and Cu in TZ. Sub-ppm levels of Cd and low ppm levels of Cu and Pb were found in an exposed population in an industrialized region in Poland but no inter-correlations were found between these three metals (Chojnacka et al, 2005), and hair levels in school children in Istanbul were found to be around 53 ng/ g for Cd and 2.4 mg/g for Pb with moderate inter-correlation (Ö zden et al, 2007). Besides recycling e-waste, the Taizhou area also holds a large number of heavy industries such as those producing plastics, valves, water pumps and petrochemical products.…”

“…soil or air particulates. There have only been a few attempts to use multivariate analysis to identify sources of hair trace elements for general populations (Nowak and Chmielnicka, 2000;Chojnacka et al, 2005;Shah et al, 2006), although those did not discuss the rigidity and reliability of the methods used. Uptake mechanisms and pharmacokinetics might alter the concentration trends of elements in hair of each individual from what is observed in the surrounding environment, making source apportionment difficult.…”

Human scalp hair samples can be used to indicate environmental and occupational exposure of heavy metals due to intensive electronic waste recycling activities. a r t i c l e i n f o a b s t r a c tScalp hair samples were collected at an electronic waste (e-waste) recycling area and analyzed for trace elements and heavy metals. Elevated levels were found for Cu and Pb with geometric means (GMs) at 39.8 and 49.5 mg/g, and the levels of all elements were found in the rank order Pb > Cu [ Mn > Ba > Cr > Ni > Cd > As > V. Besides Cu and Pb, Cd (GM: 0.518 mg/g) was also found to be significantly higher compared to that in hair samples from control areas. Differences with age, gender, residence status and villages could be distinguished for most of the elements. The high levels of Cd, Cu and Pb were likely found to be originated from e-waste related activities, and specific sources were discussed. This study shows that human scalp hair could be a useful biomarker to assess the extent of heavy metal exposure to workers and residents in areas with intensive e-waste recycling activities.

“…Interest in the hair as a marker of basic levels of metals in the human body has recently increased due to some advantages over urine or blood, particularly because it is a metabolic end product that has a recognized ability to reflect the body metal burden. Moreover, the elemental composition of the hair reflects long-term exposure, while blood or urine represents a current, or acute, situation (Chojnacka et al, 2005). The concentration of a certain metal in hair reveals a balanced mineral content of the individual body pool over a long period of time, which can only be significantly modified by exposure or intake of high quantities of trace metals.…”

Volcanoes produce and release large amounts of toxicants, and the concentration of metals in hair can be used as a biomarker of exposure to trace metals. In order to investigate whether humans exposed to volcanic emissions demonstrate higher concentrations of essential and non-essential trace metals, scalp hair of men (3-89 years) living in two areas of the Azores, one exposed to volcanic emissions and the other not, was sampled, and their content in Cd, Cu, Pb, Rb, Se, and Zn was quantified by using High Resolution Inductively Coupled Plasma Mass Spectrometry. In average, men exposed to volcanic emissions presented higher concentrations of Cd (96.9 ppb), Cu (16.2 ppm), Pb (3417.6 ppb), Rb (216.3 ppb), and Zn (242.8 ppm), but not Se (469.6 ppb). Also, strong and significant correlations were found between Cd-Rb and Pb-Rb in the exposed men. In conclusion, humans living chronically exposed to volcanic emissions show high concentrations of essential and non-essential trace metals in scalp hair, and is suggested that this type of exposure may be as harmful as living close to industrial facilities.

“…Also evaluation of the trace elements in the hair can be useful in the diagnosis of diseases such as cancer, check poisoning in humans when exposed to high doses of these elements and examination of malnutrition [1,13]. In addition, hair samples can be easily collected and conveniently stored [14].…”

Background: The measurement of trace elements in human body has proved to be of great use in the evaluation of human health and the diagnosis of various diseases. No light, however, has been shed on these elements where they concern the human intelligence. Objectives:The goal is to make a comparison between the students with a lower IQ and those having an ordinary IQ in terms of the amount of zinc and copper as two trace elements. Methods: This is a case-control study and the subjects as the patients were chosen from mentally retarded students having no particular diseases. The sample size for the patient and control was 30 for each. The hair samples of the experimental group and the ordinary students (the control group) were digested with concentrated HNO3 after being washed with water and acetone. After being digested, the values of zinc and copper in the samples were measured with atomic absorption spectroscopy. The obtained data were analyzed using SPSS-15 via two independent sample tests of significance tests.
