“…Zn in plasma ( 5 pl) was measured by electrothermal atomic absorption spectroscopy (Shaw et al 1982), and Zn in hair was measured by flame atomic absorption, after digestion for 15 min at 40% power in a CEM (Buckingham, UK) MDS-81D microwave digestion system, using a pure HN0,-H,O mixture (85 : 15, v/v) for dissolution. Hair samples were obtained from the back of the head, with stainless-steel scissors, and were thoroughly washed with aqueous sodium lauryl sulphate (10 g/l), followed by absolute ethanol.…”

A trial of zinc supplementation in young rural Gambian children

et al. 1993

The present study tested the hypothesis that inadequate Zn intake might be responsible for failure to thrive and impaired catch-up growth in young rural Gambian children, and that Z n supplements might be beneficial. Gambian children might be deprived of Zn because of its poor availability from their predominantly plant-based diet. Rural Gambian children (1 10; fifty boys, sixty girls) aged between 057 and 2.30 years were divided into two matched groups, one to receive 70 mg Zn twice weekly for 1.25 years, and the other a placebo. Growth and mid-upper-arm circumference were measured at weekly intervals throughout the study and illnesses were monitored. Capillary blood and urine samples were collected a t 0, 2 and 8 weeks. Body weights and arm circumferences showed a linear increase, plus a seasonal effect (rainy season faltering). For body weight there was no significant overall effect of the supplement. For arm circumference, a very small (2%) but significant (P < 0.01) difference favoured the supplemented group. Plasma thymulin was much lower at the first clinic than at the second and third clinics, and in vitvo Zn stimulation was greater a t the first clinic. There was, however, no effect of Zn in vivo.

“…Methods for determining biomarkers of exposure and effect. Exposure: ICP-AES, ICP-MS and AAS are the most commonly used analytical methods to determine zinc levels in plasma, bone, fingernails, hair and other biological tissues and body fluids (Alvarado et al 1991;AOAC 1990;Arnaud et al, 1991;Fan et al, 1991;Folin et al, 1991;Langmyhr et al, 1979;Luterotti et al, 1992;Marks et al, 1972;NIOSH 1984aNIOSH , 1994Panayi et al, 2002;Patterson et al, 1992;Shaw et al, 1982;Sohler et al, 1976;Szpunar et al, 1978;Takagi et al, 1988;Wilhelm et al, 1991). These methods generally are sensitive enough to measure background levels in the population and levels at which biological effects occur.…”

View full text Add to dashboard Cite

As part of its mandate, the Agency for Toxic Substances and Disease Registry (ATSDR) prepares toxicological profiles on hazardous chemicals found at Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) National Priorities List (NPL) sites that have the greatest public health impact. These profiles comprehensively summarize toxicological and environmental information. This article constitutes the release of portions of the toxicological profile for zinc. The primary purpose of this article is to provide interested individuals with environmental information on zinc that includes production data, environmental fate, potential for human exposure, analytical methods and a listing of regulations and advisories.
