Tobacco sidestream smoke: uptake by nonsmokers.

摘要: Some epidemiological studies indicate an association between passive smoking and increased risk for cancer, especially cancer of the lung. Other reports, however, have failed to confirm these findings. Biochemical analyses physiological fluids markers exposure tobacco smoke are needed as measurements uptake components by nonsmokers estimation relative passively exposed persons compared with that active cigarette smokers. This communication reports carbon monoxide, hydrogen cyanide, nicotine after under controlled conditions. The results salivary values reflect level recent within hour urinary cotinine in preceding hours. N -Nitrosoproline has been shown serve indicator endogenous -nitrosamine formation smokers; yet, preliminary do not excretion -nitrosoproline is following short-term exposure. In infants, first field suggest a correlation tobacco-smoke-polluted environments levels continine both serum urine.
