To explore human biomonitor of persistent organic pollutants (POP) for public health risk assessment, extractable organohalogens (EOX), extractable persistent organohalogens (EPOX) and some selected organochlorine pesticides (OCP) and polychlorinated biphenyls (PCB) in children hair from urban and rural regions of Beijing, China, were measured by(More)
Air pollution has become a serious problem in the Pearl River Delta, South China, particularly in winter due to the local micrometeorology. In this study, atmospheric polycyclic aromatic hydrocarbons (PAHs) were monitored weekly in Shenzhen during the winter of 2006. Results indicated that the detected PAHs were mainly of vapor phase compounds with(More)
In order to study the daily Pb absorption in fetus and to monitor the main Pb sources in prenatal fetus, we have investigated several cases of Pb distribution along the longitudinal axis of fetal hair. The changes of Pb levels in the pregnancy period, even the daily changes of Pb levels can be detected in the hair. Therefore, by analyzing the Pb(More)
Particulate matter (PM) emission rates from two high‐rise layer barns (barns 1 and 2) were measured from 1 August 2004 to 31 January 2005. A commercial particulate impaction curtain (PIC) was installed parallel to the first floor sidewalls and upstream of the exhaust fans of barn 2 for PM reduction by impaction. Tapered element oscillating microbalance(More)
Organohalogens, especially organochlorinated compounds (OCs) such as polychlorinated biphenyls (PCBs), have long been recognized as a potential threat to human health and, therefore, these compounds have been widely investigated in foods [3, 27], vegetation [9, 14], and the atmosphere [1, 11]. Recently, interest in using extractable organohalogens (EOX) as(More)
Gatifloxacin (GAFX), P-aminomethylbezoic acid (PAMBA), cefazolin (CFZL) and cefminox (CMNX) can be combined and administered perorally or intravenously, and are excreted mainly into the urine. A novel capillary zone electrophoresis (CZE) method was developed, for the first time, for an effective separation and simultaneous determination of the said four(More)
