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。
In this paper, 81 workers (44 males and 37 females) producing phenolic resin in the plastic factory were investigated. Contrasting 72 workers (36 males and 36 females) in the carton factory that did not touch any toxic substances, the results showed that the plastic The phenolic resin concentration in the air of workshop phenolic resin workshop was 29.67mg / m3 (fixed point sampling) and 27.60mg / m3 (individual sample) on average, the score and detection of phenolic resin on the skin, mucous membrane and upper respiratory symptoms of workers Rates were significantly higher than those in the control group; small airway exposure in exposed workers showed a significant drop in V25 and V50 and a significantly higher rate of abnormal detection with dose-response (response). Small airway changes as the evaluation index, the initial recommended maximum allowable concentration of phenolic resin 12mg / m3.
