Determination of 43 polycyclic aromatic hydrocarbons in air particulate matter by use of direct elution and isotope dilution gas chromatography/mass spectrometryZheng Li
Centers for Disease Control and Prevention, 4770 Buford Highway F 53, Atlanta, GA 30341, USA
Anal Bioanal Chem 396:1321-30. 2010..The results showed distinct seasonal and spatial variation and were consistent with an earlier study measuring PM(2.5) samples using an ASE method, further demonstrating the compatibility of this method and the commonly used ASE method...
Evaluation of exposure reduction to indoor air pollution in stove intervention projects in Peru by urinary biomonitoring of polycyclic aromatic hydrocarbon metabolitesZheng Li
Centers for Disease Control and Prevention, 4770 Buford Highway, Mail Stop F 53, Atlanta, GA 30341, USA
Environ Int 37:1157-63. 2011..The observed OH-PAH concentration in this study was comparable or higher than the 95th percentile of the general U.S. population, even after the stove intervention, indicating a high overall exposure in this population...
Assessment of non-occupational exposure to polycyclic aromatic hydrocarbons through personal air sampling and urinary biomonitoringZheng Li
Centers for Disease Control and Prevention, 4770 Buford Highway F 53, Atlanta, GA 30341, USA
J Environ Monit 12:1110-18. 2010..These findings suggest that this group of non-occupational subjects were exposed to naphthalene primarily through indoor air inhalation, and exposed to other PAHs such as pyrene mainly through ingestion...
Variability of urinary concentrations of polycyclic aromatic hydrocarbon metabolite in general population and comparison of spot, first-morning, and 24-h void samplingZheng Li
Centers for Disease Control and Prevention, Atlanta, GA 30341, USA
J Expo Sci Environ Epidemiol 20:526-35. 2010..These data will aid in the design of future studies of PAHs and possibly other biologically non-persistent chemicals and in the interpretation of their analytical results...
Excretion profiles and half-lives of ten urinary polycyclic aromatic hydrocarbon metabolites after dietary exposureZheng Li
Centers for Disease Control and Prevention, 4770 Buford Highway, Atlanta, GA 30341, USA
Chem Res Toxicol 25:1452-61. 2012..It is essential to consider the relatively short half-life, the timing of samples relative to exposures, and the effect of diet when conducting PAH exposure biomonitoring studies...
Concentration and profile of 22 urinary polycyclic aromatic hydrocarbon metabolites in the US populationZheng Li
Centers for Disease Control and Prevention, National Center for Environmental Health, 4770 Buford Highway, F53 Atlanta, GA 30341, USA
Environ Res 107:320-31. 2008..The correlation coefficients between 1-PYR and other metabolites ranging from 0.17 to 0.63 support the use of 1-PYR as a useful surrogate representing PAH exposure...
Measurement of urinary monohydroxy polycyclic aromatic hydrocarbons using automated liquid-liquid extraction and gas chromatography/isotope dilution high-resolution mass spectrometryZheng Li
National Center for Environmental Health, Centers for Disease Control and Prevention, 4770 Buford Highway, F17, Atlanta, Georgia 30341, USA
Anal Chem 78:5744-51. 2006..This method is currently applied to epidemiological studies, such as the National Exposure and Nutrition Examination Survey (NHANES), to measure human exposure to PAHs...
Lung tumor production and tissue metal distribution after exposure to manual metal ARC-stainless steel welding fume in A/J and C57BL/6J micePatti C Zeidler-Erdely
Pathology and Physiology Research Branch, National Institute for Occupational Safety and Health, Health Effects Laboratory Division, 1095 Willowdale Road M S L2015, Morgantown, WV 26505, USA
J Toxicol Environ Health A 74:728-36. 2011..In addition, long-term extrapulmonary tissue alterations in metals in the susceptible A/J mouse suggest that the adverse effects of this fume might be cumulative...
Diethylene glycol in health products sold over-the-counter and imported from Asian countriesJoshua G Schier
Centers for Disease Control and Prevention, Atlanta, GA, USA
J Med Toxicol 7:33-8. 2011..Based on current standards, these levels probably do not represent an acute public health threat. Additional research focusing on why DEG is found in these products and on the minimum amount of DEG needed to result in toxicity is needed...
Automated solid-phase extraction method for measuring urinary polycyclic aromatic hydrocarbon metabolites in human biomonitoring using isotope-dilution gas chromatography high-resolution mass spectrometryLovisa C Romanoff
Centers for Disease Control and Prevention, National Center for Environmental Health, 4770 Buford Highway NE, Mailstop F17, Atlanta, GA 30341 3724, USA
J Chromatogr B Analyt Technol Biomed Life Sci 835:47-54. 2006..6 and 17.1%, N>156), and the necessary specificity. We used the method to analyze nearly 3000 urine samples in the fifth National Health and Nutrition Examination Survey (NHANES 2001-2002)...
