摘　　要：本文对塑料厂生产酚醛树脂的８１名工人（男４４名、女３７名）进行调查，以不接触任何有毒物质的纸箱厂７２名工人（男３６名、女３６名）为对照，结果表明塑料厂酚醛树脂生产车间空气中的酚醛树脂浓度平均为２９．６７ｍｇ／ｍ３（定点采样）和２７．６０ｍｇ／ｍ３（个体采样），酚醛树脂接触工人的皮肤、粘膜及上呼吸道症状的评分及检出率显著高于对照组；接触工人的小气道受损，表现为Ｖ２５和Ｖ５０的显著下降及异常检出率显著增高，且有剂量－效应（反应）关系。以小气道的改变为评价指标，初步建议酚醛树脂的最高容许浓度为１２ｍｇ／ｍ３。ightyone workers exposed to phenol formaldehyde resin (PFR)(44 male, 37female) in a plastic factory were in vestigated in the study, with seventy two workers nonexposed to any toxic substances (36 male, 36 female) in a paperbox factory as control. The result showed that average concentration of PFR in workplace was 29.67mg/m 3(set sampling) and 27.60mg/m 3(grab sampling), score and detecting rate of symptom of skin, mucous and upper respiratory tract were significantly higher in exposed workers than in the nonexposed, change of V 25 and V 50 of the exposed (V 25 and V 50 declining greatly and detecting rate of abnormal V 25 and V 50 increasing significantly) manifested damage of small airways, and there existed exposure effect(response) relationship. According to change of small airways, we preliminary suggested 12mg/m 3 as maximum allowable consentration(MAC).
