| 摘 要： | 对１４０名ＴＰＡ作业工人和同一地区年龄、性别、身高、体重、吸烟情况类似的７０名正常对照工人进行肺功能的测定分析。接触组ＭＶＶ、ＰＥＦＲ、Ｖ７５、ＰＥＦＲ／Ｈ、Ｖ７５／Ｈ显著低于对照组（Ｐ＜０．０５）；多因素分析表明，ＰＥＦＲ、Ｖ７５、ＰＥＦＲ／Ｈ、Ｖ７５／Ｈ的下降与接尘因素有关；寿命表法分析提示，ＦＥＶ１的累积异常率与累积接尘量有一定的接触水平——反应关系。据此，本文提出了ＴＰＡ粉尘的接触限值为４．３０ｍｇ／ｍ３。

| Abstract: | The pulmonary function was examined in 140 workers exposed to terephthalic acid(TPA) and 70 controls in the same residence area as non exposure workers.The exposed workers exhibited significant decrease in MVV,PEFR,V 75 ,PEFR/H and V 75 /H( P <0 05) in comparison with the controls.The decrease was found to be associated with increased TPA concentration by multiple regression analysis.The results of life table method analysis suggested that there was an exposure level response relationship between accumulative TAP dust exposure and lower FEV1.According to the results reported here,an exposure limit for TPA dust was proposed to be 4 30 mg/m 3. |
