人体中有数十种化学元素,这些元素在人体中的多少取决于人体所处的地球化学环境和食物结构等因素。据有关资料介绍,各种元素在人体中的多少及变化在一定程度上反映了人体的健康状况和环境污染对人体的影响。那么如何才能测得人体元素含量及变化呢?利用头发作样品进行检测可得到较为理想的结果。因为头发是人体排泄微量元素的途径之一,经测试分析表明,头发中的大多数元素都比血液中含量高,通常都在10倍以上,有些不易在血液中检查出来的元素在头发中也是容易测到的。同时,头发取样方便并且易于贮存。故有人称头发为反映人体与环境关系的“记录丝”。此外,还可利用微量元素的发量解决一些历史悬案,例如拿破仑之死等。区分智力高低据有关资料介绍,通过分析锌、铜、铅、镉、锰、锂、碘等十四种元素在头发中的浓度,可以区分正常儿童与低能儿童,其准确率可达98%。低能儿童的发铅、发镉、发锰量偏高,而发锂、发铬量偏低。在校学习的青少年也有类似的情况,学习成绩差的其
There are dozens of chemical elements in the human body. The amount of these elements in the human body depends on the geochemical environment and food structure in which the human body is located. According to the relevant information, the amount and variety of various elements in the human body reflect to a certain extent the impact on the human body of the human health and environmental pollution. So how to measure the human element content and changes? The use of hair samples for testing can be more satisfactory results. Because the hair is one of the ways the human body excretion of trace elements, the test analysis showed that most of the hair elements are higher than the blood content, usually more than 10 times, some of the elements are not easy to check in the blood is also in the hair Easy to measure. At the same time, hair sampling is easy and easy to store. So some people call the hair to reflect the relationship between the human body and the environment “record silk ”. In addition, the amount of trace elements can also be used to solve some of the historical issues, such as the death of Napoleon. Distinguish between intelligence According to the relevant information, through the analysis of zinc, copper, lead, cadmium, manganese, lithium, iodine and other 14 kinds of elements in the hair concentration, you can distinguish between normal children and low energy children, the accuracy rate of up to 98%. Low-energy children’s hair lead, hair cadmium, hair manganese is high, and hair lithium, hair chromium low. There are similar situations in adolescents who are studying at school, and they have poor academic performance
