Urinary concentrations of acrylamide (AA) and N-acetyl-S-(2-carbamoylethyl)-cysteine (AAMA) and associations with demographic factors in the South Korean population.

Acrylamide (AA) and N-acetyl-S-(2-carbamoylethyl)-cysteine (AAMA) are important urinary biomarkers of acrylamide exposure in human biomonitoring, because AA is classified as a probable carcinogen in humans. In this study, urinary AA and AAMA were assessed in the South Korean adult population aged 18-69, based on the Korean National Human Biomonitoring Survey conducted in 2009. Urinary metabolites in samples were analyzed with LC-MS/MS system.

Korea National Survey for Environmental Pollutants in the human body 2008: 1-hydroxypyrene, 2-naphthol, and cotinine in urine of the Korean population.

The Korea National Survey for Environmental Pollutants in the human body conducts representative Korean population studies, which were first initiated in 2005 in Korea. This study was conducted from 2008 to 2009 to determine the exposure levels of polycyclic aromatic hydrocarbons and nicotine in the Korean general population. The study population consisted of 4702 adult subjects from 196 sampling locations including coastal, rural, and urban areas.

Korea National Survey for Environmental Pollutants in the Human Body 2008: heavy metals in the blood or urine of the Korean population.

Background: Recently, there have been several nationwide episodes involving imported toys contaminated with toxic metals and environmental hormones. In addition, cadmium intoxication has occurred due to soil contamination with cadmium from abandoned metal mines.

Objectives: To investigate the distribution, extent and factors influencing the levels of toxic metals in the blood or urine of the Korean general population over twenty years of age, we studied the blood or urine concentrations of heavy metals in a representative sample of 5087 Koreans in 2008.
