Environmental Tobacco Smoke and Lung Cancer — Recent Aspects on Confounders and Dose Levelsew describes the mechanisms by which substances taken into the body by the oral route may cause lung cancer. Two major possibilities are metabolism in the gut with subsequent absorption of carcinogenic compounds or selective accumulation of agents in the lung and local metabolism, particularly in thChromatic 发表于 2025-3-25 19:00:22
Urinary Mutagenicity, Hydroxyphenanthrene, and Thioether Excretion After Exposure to Environmental Tm CO (Experiment 2). During the control and the exposure period the room air was monitored for CO, NO, NO., nicotine and formaldehyde. Biomonitoring included determination of carboxyhemoglobin (COHb), cotinine in serum and urine, and urinary excretion of five different monohydroxyphenanthrenes (OH-PJudicious 发表于 2025-3-25 21:02:25
