The Effect of Indoor Heating with a Coal Range on 1-Hydroxypyrene in Urihe
室内小煤炉采暖对尿中1-羟基芘的影响

The changes of 1-hydroxypyrene in urine of the same households have been observed in the periods of heating with coal ranges or central heating or non-heating. The urinary 1-hydroxypyrene of several groups of people has been detected as an index. The results of statistic analysis shown that its level in the persons of indoor heating with coal ranges is higher than that of central heating or that in non-heating period. So the results demonstrate that indoor air pollution of polynuclear aromatic hydrocarbons(PAHs)is serious in the households with burning coal. It is suggested that urinary 1-hydroxypyrene can be used as a specific sensitive index for human exposure to genotoxic PAHs from burning coal.
