Chinese children with autism: A multiple chemical elements profile in erythrocytes.

Unlabelled: Several lines of evidence suggested that abnormal levels of certain chemical elements may contribute to the development of autism spectrum disorders (ASD). The present work aimed to investigate the multiple chemical elements profile in the erythrocytes of autistic versus typically developing children (TDC) of China. Analyses were carried out to explore the possible association between levels of elements and the risk as well as the severity of ASD.

Manifestation of the Se, Cd and Mo levels in different components of the peripheral blood of Sprague-Dawley rats poisoned via the respiratory tract.

This study aimed to explore the effects of exogenous element exposure via the respiratory tract on the Se, Cd and Mo concentrations in different components of the peripheral blood in rats as well as to determine the correlations of the three trace elements concentrations among the components. The Sprague-Dawley rats were randomly divided into a control group and several experimental groups treated with different doses. The rats were exposed to a mixed trace element solution through 10 days of intratracheal instillation.

[Effects of lead exposure on 18 elements in blood and excretions in rats].

Objective: To investigate the effects of lead exposure on lead and other metal elements contents in rats.

Methods: SD rats were randomly divided into control group and several experiment groups of different doses. The rats were exposed to lead acetate through intragastric administration every other day for 5 times.

[Investigation of the enrichment and separation of lead and lead isotopes in simulated blood matrix].

The enrichment and separation method was used in the present paper to overcome the influence of matrix effect on the determination of lead concentration and isotope ratios. The patented method was used to enrich and separate the lead in simulated blood matrix; the lead concentrations and isotope ratios were determined by ICP-MS before and after enrichment and separation. The recovery rate of Pb is more than 99% through this method while the removal rate of major impurity ions such as Na, K is about 80%.
