Study on High-Temperature Working Environment with the Excretion and the Levels In Vivo of Vitamin C among Heat-Exposed Workers

In order to study the effect of high temperature working environment on the vitamin C excretion of steel workers and the levels in vivo, we survey and analyze vitamin C in sweat and urine from the 226 heat-exposed workers and 39 non-heat-exposed workers at the same workshop. The results of the survey show that sweating is the main way for the excretion of vitamin C under the high temperature environment, and this is also one of the main reasons for the in vivo levels of vitamin C declining. Consequently, some necessary measures should be taken to avoid damage caused by heat-exposed operation and ensure the workers enjoy good health.
