[Study on monitoring index of individual exposure dose of volatile organic compounds in environment].

In order to study the monitoring index of individual exposure dose of volatile organic compounds (VOCs) in environment, the thermal desorption capillary gas chromatographic (TD-GC) analysis was used to examine the VOCs level in air and the expired breath of female workers. Headspace solid phase micro-extraction gas chromatography (SPME-GC) was applied to determine the blood concentration of VOCs in female workers. The results from epidemiological study showed clearly that concentration of 10 subtypes of VOCs in blood, environmental air and expired breath from exposure group were higher than those from control group.

[Fine particles pollution and its impact on the expression of inflammation cytokine IL-6].

To investigate fine particles (PM2.5) pollution and its impact on the expression of inflammation cytokine IL-6. Two cities, namely Taiyuan and Beijing, were selected to represent two different types of air pollution.

[A portable analyzer for determination of iodine in human urine].

A instrument based on principle of ion chromatography and amperometric detector for quick determination of iodine in urine are introduced in this paper, which covers from signal collection and treatment to data analysis. It presents the principle of hardware and software method to obtain the determination by using computer technology as well as the method of analysis of chromatogram. The instrument possess advantage of single, sensitive and simple.
