In the determination of organic solvents in workplaces direct reading tube method have been in Korea for decades. But this method is less accurate and couldn't measure TWA (Time Weighted Average) for 8 hours. Authors tried to detect Toluene concentration in S factory by using charcoal tube according to NIOSH method. The concentration was 158.8ppm. We propose this charcoal tube method should be substituted to get accurate results and to protect employee in workplaces related with solvents.

AbstractAbstract PDF
To determine Pb level in blood, we usually used to pull out about 5ml blood from venous vessel and this sample was digested with acids to decompose organic matter and then determined the Pb contents by Atomic Absorption Spectrophotometer with flame. But recent trend in quan titating Pb in small amount of sample is very much recommended in clinical chemistry specially pediatrics, and industrial hygiene and occupational health area. Authors tried to determine Pb contents in small amount blood of 25 microliter by using capillary tube method and got the possibility of determination of ng amount of Pb in 25yl whole blood sample without any pretreatment of sample.

AbstractAbstract PDF
We are calling the erupting ground water as drug water or mineral water in Korea and thinking those water and food making water. Authors tried to investigate the evidence of contamination by user on the 10 erupting ground water and gained following results: 1. All of the mineral waters on 10 area in Seoul were unfittable to drinking water standard. 2. In the view of the bacteriology 80% were contaminated by coliform group. 3. The highest value of the free carbon dioxide contents were 652.96 ppm at Sam Sun Mineral Water.
