The lead burdens for children and mothers exposed to lead-contaminated soils and dusts have been investigated in a rural district with minimal atmospheric pollution. A significant relationship was observed between the lead content of blood and hair of children exposed to soils of mean lead content in the range 420-13,969 p.p.m. The blood lead concentration of children was consistently greater t...

a survey on lead intoxication in lead mine workers was carried out among khanehsorme, lead miners in najafaabad and also in ab-bagh lead miners in shahreza, both located in district of esfahan, iran. the studies were carried out on 62 miners out of 82 employees in khanehsorme, 25 miners out of 27 employees in ab-bagh lead miners and 47 rural inhabitants in the surroundings of mines were selecte...

Among epigenetic factors leading to increased prevalence of juvenile neuropsychiatric disorders, including autism spectrum disorder, exposure to metals, such as lead (Pb) have led to conflicting results. The aim of the present study was to determine the levels of Pb in the urine of children with autism spectrum disorder (ASD) compared with typically developing children (TD) age- and sex-matched...

Received 19 March 2013, Revised 26 June 2013, Accepted 29 June 2013 -------------------------------------------------------------------------------------------------------------------------------------------Abstract The aim of present study was to determine the lead (Pb) distributions in blood and prevalence of elevated Pb exposure among children, age ranged (5–10 years), residing near industri...

A method has been developed for direct determination of lead in wine by graphite furnace atomic absorption spectrometry (GFAAS) with Zeeman-effect background correction. The thermal behaviour of Pb during pyrolysis and atomisation stages was investigated without matrix modifier and in the presence of Pd(NO(3))(2), Pd(NO(3))(2) + Mg(NO(3))(2) × 6H(2)O, and NH(4)H(2)PO(4) + Mg(NO(3))(2) × 6H(2)O ...

Introduction: The effects of X-rays on carcinogens have been proven in recent years. Today, lead is used in many devices such as lead covers, thyroid protectors to protect the body against x-rays. But this equipment contains many disadvantages such as, Toxicity, High weight and Lack of flexibility. Today, newer methods, such as semi-solid skin care products (cream, ointment), a...

in this paper a chemical deposition procedure for the preparation of lead sulfide thin film ispresented. the details of the preparation method are described. the influence of hydrazine hydrate onthe microstructure and deposition rate of lead sulfide thin film has been investigated. the concentrationof the lead ions in the deposition bath decreases more slowly when the hydrazine hydrate is added...
