本文研究了地磁干扰对132名电力工人尿中褪黑素代谢产物6-羟基褪黑素硫酸盐（6-OHMS）排泄的影响。使用局部（等效振幅或A（K），Boulder，CO）和全球（平均对极或aa）指数评估地磁活动。个人暴露于60赫兹的MF和光，获得使用数据记录仪。地磁活动和6-OHMS之间的关系进行了评估，调整了年龄，光照和参与月份。当36小时A（K）或aa值超过30 nT时，平均过夜6-OHMS排泄量较低。当地磁活动增加与60 Hz MF升高或环境光暴露减少相结合时，观察到6-OHMS排泄的更大减少。(C)1999爱思唯尔科学爱尔兰有限公司保留所有权利。
The effects of geomagnetic disturbances on urinary excretion of the melatonin metabolite, 6-hydroxymelatonin sulfate (6-OHMS), were studied in conjunction with 60 Hz magnetic field (MF) and ambient light exposure in 132 electric utility workers. Geomagnetic activity was assessed using a local (equivalent amplitude or A(K), Boulder, CO) and global (average antipodal or aa) index. Personal exposures to 60 Hz MFs and light were obtained using data-logging meters. The relationship between geomagnetic activity and 6-OHMS was assessed with adjustment for age, light exposure, and month of participation. Mean overnight 6-OHMS excretion was lower on days when the 36-h A(K) or aa values exceeded 30 nT. A greater reduction in 6-OHMS excretion was observed when increased geomagnetic activity was combined with elevated 60 Hz MF or reduced ambient light exposures. (C) 1999 Elsevier Science Ireland Ltd.
