4-10 Gas-Chromatograph method
Chromatography
A substance is passed between a stationary phase (solid or liquid) and a mobile phase (liquid or gas) flowing in contact with it, and the difference in affinity for both phases is used to generate the target substance. How to separate components.
When the mobile phase is liquid, it is called liquid chromatography, and when it is gas, it is called gas chromatography.

産業医学 (有機溶剤、鉛) 関連検査

産業医学関連検査は、有機溶剤作業者、鉛作業者を対象として、体内に有機溶剤や鉛がどの程度取り込まれているかを定期的にチェックすることを主な目的としているため、結果の評価については、正常・異常の鑑別を目的としたものではなく、作業環境を含めた総合的な判断が必要とされています。
また、労働安全衛生法に基づく各中毒予防規則では、各健康診断結果報告書を、所轄の労働基準監督署長に提出することが定められています。

Occupational Medicine (Organic solvents, Lead) Related Test

The occupational medicine-related test is mainly intended to regularly check the level of organic solvents or lead intake in the living body for organic solvents and lead workers. Therefore, the evaluation of the results requires a comprehensive judgment including the work environment, rather than the one intended to differentiate normality and abnormality.
In addition, each Regulation on Prevention of Poisoning based on the Industrial Safety and Health Act stipulates that each report of the results of a medical examination shall be submitted to the Chief of the Labour Standard Inspection Offices in charge.

From the Report of the Results of a Medical Examination for Organic Solvents (Regulation on Prevention of Organic Solvent Poisoning, Form No. 3-2), the Report of the Results of a Medical Examination for Lead (Regulation on Prevention of Lead Poisoning, Form No. 3)
