a total number of 67 workers of teheran battery workshops were investigated for probable lead absorption due to the working with lead storage batteries. twenty workers with other occupations were selected as control group. blood and urine analysis were carried out for both groups. lead content of the urine in about 95.5% of the subjects was below 10 μg/100 ml. two subjects showed higher concent...

Metal (Cr, Co, Cu, Zn, Cd, Pb, Ni) and metalloid (As) accumulation was studied in roadside soil and wild rat (Rattus sp.) samples from near a Pb-Zn mine (Kabwe, Zambia) and the capital city of Zambia (Lusaka). The concentrations of the seven metals and As in the soil samples and Pb in the rat tissue samples were quantified using atomic absorption spectroscopy. The concentrations of Pb, Zn, Cu, ...

The concentration of Cadmium (Cd) and lead (Pb) in different cigarette brands sold and/or produced in Saudi Arabia were determined by atomic absorption spectrometry (AAS). Average levels of Cd and Pb in different cigarette brands in Saudi Arabia were 1.81 and 2.46 μg g1 (dry weight), respectively. The results obtained in this study estimate the average quantity of Cd inhaled from smoking one pa...

OBJECTIVES The aim of this study is to describe blood lead levels (BLLs) and the prevalence of elevated blood lead levels (EBLLs) in children aged 0-6 years old and to analyze the BLL trend in children from 2009 to 2013 in China. METHODS A total of 124,376 children aged 0-6 years old were recruited for this study from January 1st 2009 to December 31st 2013. Their blood lead levels were analyz...

The aim of this work was to verify whether there are statistically significant correlation between the concentrations of lead in blood (Pb-B) and urine (Pb-U). Electrothermal atomic absorption spectrometry was used in the determination of lead concentration in biological material. Venous blood and spot urine were collected from workers occupationally exposed (95), adults (130) and children up t...

background: cigarette butts have been shown to release numerous kinds of chemicals such as heavy metals in water and may be a continual source of aquatic environments contamination after discarding. the objective of the present study was to determine the concentration of cd and pb in cigarette filters of different iranian and non-iranian brands in smoked and non-smoked samples. methods: ten dif...

a low haemoglobin but none had symptoms or signs that were likely to be due to lead absorption. A further i8 men had haemoglobins of 89% (13 g./Ioo ml.) or less. None was thought to be low due to lead absorption. The absence of symptoms, signs, and low haemoglobins in association with relatively high blood leads is unlikely to be due to errors in blood lead or haemoglobin estimation. Alternativ...

in this study, 60 composite samples of dill and onion from two different cultivated areas in khozestan province, iran, were collected and analyzed for the presence and determination of lead and cadmium by flame atomic absorption spectrometry. samples were burned according to aoac at 450 °c, and the residue was dissolved in nitric acid. lead and cadmium contents were determined using calibration...

The fractional determination of triethyl lead, diethyl lead, inorganic lead and total lead in the urines of a patient with tetraethyl lead poisoning was performed by means of hydride generation-flameless atomic absorption spectrometry. The chemical species of lead in the urine 21 days after the exposure comprised about 50% diethyl lead, about 48% inorganic lead and about 2% triethyl lead. The f...
