The nutritional factors which affect lead absorption have been studied. Synthetic diets of known composition were compounded to contain 0-075% Pb as PbCl2 labelled with 203Pb. Rats were exposed to lead for periods of 48 hr. The dietary intake was then measured and the absorption of lead determined by means of a whole-body counter. Lead absorption was increased by high fat, low mineral, low prot...
This study was conducted to determine concentration of lead (Pb) in the liver of flathead (Platycephalus indicus) in Minab, Qeshm Island and Khamir Port in the Persian Gulf during winter and summer (n= 30). Concentration of lead was measured using Atomic Absorption Spectrometry (AAS). The results showed that, there were significant differences between stations for the concentration of lead in ...
in present study we determine the zinc and lead levels in human blood samples by differential pulse polarography under optimum experimental conditions (ph=7.5, scan rate=5mv/s and pulse amplitude=50mv) the polarographic reduction peaks of zn and pb were examinedin the -0.72 v and-0.15 respectively. the zinc and lead content can be determined by in comparison with their standard solutions. accor...
