“…Health effects of exposure to platinum and palladium reviewed in a previous study (1) indicated that soluble forms of platinum can create allergic responses in sensitive individuals. The catalysts used small quantities of platinum and palladium, and there have been some indications of emissions of particles of these metals.…”

Three age groups (children, young adults, and mature adults) were sampled twice for blood, urine, hair, and feces. Air, water, and soil samples were collected in the areas of the residences of the two populations. The primary objective of this study was to obtain baseline levels of these metals prior to the introduction of the catalytic muffler. The samples were collected in September 1974. This paper reports on an investigation aimed at establishing baseline levels of platinum, palladium, and lead in the environment and in human populations prior to distribution of 1975 automobiles so that determination can be made in future years of changes in levels of the metals. To this purpose, samples of air, soil, blood, urine, fecal matter, and hair clippings were collected and analyzed for the presence of platinum, palladium, and lead. Lead analysis was included because of the interdependence of lead with the usage of catalytic converters, i.e., requirement for unleaded gasoline. The samples were collected in an area of high exposure to auto emissions and in a control area with much lower exposure. Methods Study Design

Araflt›rmaS on yüzy›llarda sanayide meydana gelen geliflmeler, pek çok sorunu da beraberinde getirmifltir. Sanayi iflçileri meslekleri nedeni ile kadmiyum (Cd), kurflun (Pb), arsenik (As), civa (Hg) gibi a¤›r toksik elementlere maruz kal›rlar. ‹nsan vücudunda mg/L (ppm) veya (ppb) düzeyinde bulunan elementler, eser elementler olarak adland›r›l›r-lar. Bu elementler insan vücuduna yiyecekler, hava, su, sigara gibi de¤iflik yollarla al›n›r. Vücuda yararl› olmayan -çok az al›nsa da -at›lmay›p, zamanla toksik etkiler Özet Amaç: Bu çal›flma Diyarbak›r kent merkezinde kapal› ve aç›k otopark çal›flanlar›n›n kan kurflun, kadmiyum, krom ve total antioksidan kapasitelerini de¤erlendirmektedir.Yöntem: Bu kesitsel araflt›rmada Diyarbak›r kent merkezinde 49 kapal› otopark ve 50 aç›k otopark çal›flan› toplam 99 kifliden venöz kan al›nm›flt›r. Bulgular:Otopark çal›flanlar›n›n kan de¤erleri flöyledir: Kandaki ortalama kurflun de¤eri; kapal› otoparkta 268,06 μg/lt, aç›k otoparkta 181,53 μg/lt'dir; iki grup aras›ndaki fark istatistik olarak anlaml› de¤ildir. Kandaki ortalama kadmiyum de¤eri kapal› otoparkta 59.20 μg/lt, aç›k otoparkta 33.21 μg/lt'dir; gruplar aras› fark istatistiksel olarak önemlidir. Kandaki ortalama krom düzeyi kapal› otoparkta 5.02 μg/lt ve aç›k otoparkta 3.69 μg/lt'dir; iki grup aras›ndaki fark istatistik olarak anlaml› de¤ildir. Total antioksidan kapasitesi (TAK) ortalamas› kapal› otoparkta (1.60), aç›k otoparktakinden; (1.50) düflüktür; iki grup aras›ndaki fark istatistiksel olarak anlaml›d›r. Sonuç:Gerek kapal›, gerekse aç›k otopark çal›flanlar›n›n kan kurflun, kadmiyum ve krom düzeyleri standart de¤erlerin üzerinde-dir. Otopark çal›flanlar›n›n sa¤l›k durumlar› sürekli de¤erlendiril-melidir.Anahtar sözcükler: Otopark çal›flanlar›, kurflun, kadmiyum, krom, total antioksidan kapasite. SummaryObjective: This study aimed to evaluate the blood lead, cadmium, chromium and total antioxidant capacity (TAC) of closed and open car park station workers.Methods: This was a cross-sectional study. In Diyarbakir city center, venous bloods of 49 closed and 50 open car park station workers were collected and analyzed using atomic absorbsion spectrophotometry. Results: Mean blood lead level of closed car-park station workers (268,06 μg/lt) was not statistically different from open car park station workers (181,53 μg/lt). But for cadmium and chromium mean blood levels, there was statistically significant difference between two groups. Mean blood cadmium level was 59.20 μg/lt in closed car-park workers and 33.21 μg/lt in open car-park workers. Chromium levels were 5.02 μg/lt and 3.69 μg/lt respectively. Mean TAC level was 1.60 in closed auto park workers and 1.50 in open car park workers. There was a statistically significant difference between the two groups.Conclusions: Both in closed and open car park workers mean blood lead, cadmium and chromium levels were found high. Health status of car park station workers should be followed up continuously.

“…Hair samples are easy to obtain, heavy metal analysis of hair is precise, and numerous studies show that hair metal concentrations accurately reflect exposure to metal pollutants (Nishiyama and Nordberg, 1972;Sorenson, Melby, Nord, & Petering, 1973;Corridan, 1974;Reeves, Jolley, & Buckley, 1975;Johnson, Tillery, and Prevost, 1975;Oleru, 1976;Chatt, Roberts, and Jervis, 1977). Blood primarily reflects the acute effects of recent exposure to metals, whereas hair incorporates lead from the body over longer periods of time and thus is a more sensitive indicator of long-term exposure to low levels of metals than is blood (Gordon, 1976).…”

Childhood exposure to metal pollutants routinely encountered in the environment is an issue of importance to the field of behavior disorders. Metal pollutants at low levels, far below those associated with clinical metal poisoning, are associated with a spectrum of behavior disorders.This review addresses a set of environmental and diet variables to reduce metal exposure which are potentially within the realm of control of child, parent, and health or educational professional working with the family.It is well established that metal pollutants are neurotoxins, and that children who survive the effects of metal poisoning are often left with permanent neurological sequelae, including severe behavior disorders (Weiss, 1983). Now, there is a consensus that lesser levels of metals considerably below those associated with metal poisoning, are, also a causative factor in neurologic dysfunctions, including behavior disorders. The empirical foundation of this position is the variety of studies conducted since the early 1970s demonstrating significant correlations between low and moderate metal levels and childhood behavior dysfunctions.
