人体从外界摄入的微量元素,可蓄积在毛发中,其含量与所接触的环境有关,因此,以毛发来衡量微量元素与环境接触的关系,已日益受到人们的重视。 一般认为,毛发中的微量元素有内部蓄积和外部污染两部分,洗涤的目的,就是要去除外部污染的那部分元素。 洗涤的方法、种类很多。本文对一些头发洗涤方法作了比较,并且对“海鸥”洗涤剂的浓度,洗涤液pH,洗涤时间、温度等作了实验探讨,现报告如下。 Trace elements absorbed by the body from the outside world, can accumulate in the hair, its content and the environment in contact with, therefore, to measure the relationship between hair and trace elements in contact with the environment, has been increasingly people’s attention. Generally believed that the trace elements in the hair have internal accumulation and external pollution in two parts, the purpose of washing is to remove the external pollution that part of the element. Washing methods, many types. In this paper, some hair washing methods were compared, and the “Seagull” detergent concentration, washing liquid pH, washing time, temperature and other experiments were made, are as follows.
