Plasma gamma-hexachlorocyclohexane (gamma-HCH) and three urinary trichlorophenols were measured in forestry workers who were engaged in planting seedlings treated with gamma-HCH. These two procedures were assessed as potential biological monitoring methods and the data were compared with reported clinical symptoms. The measurement of plasma gamma-HCH was considered to be a feasible and valid monitoring method for use in routine practice and is a useful indicator of gamma-HCH absorption. The data were used to illustrate the need to be vigilant about personal hygiene and the efficacy of protective clothing. Plasma gamma-HCH concentrations above 70 nmol/l were measured in two workers which coincided with persistent non-specific clinical symptoms. Trichlorophenols were identified in urine but the extensive and variable metabolism of gamma-HCH makes this approach less suitable for biological monitoring.
对从事种植用γ-六氯环己烷处理过的幼苗的林业工人,测定了其血浆γ-六氯环己烷(γ-HCH)和三种尿中三氯酚。这两种检测方法被评估为潜在的生物监测方法,并将数据与报告的临床症状进行了比较。血浆γ-HCH的测定被认为是一种在常规实践中可行且有效的监测方法,是γ-HCH吸收的有用指标。这些数据用于说明对个人卫生保持警惕的必要性以及防护服的功效。两名工人的血浆γ-HCH浓度高于70 nmol/l,这与持续的非特异性临床症状相符。在尿液中检测到了三氯酚,但γ-HCH广泛且多变的代谢使得这种方法不太适合用于生物监测。
