【摘要】 本文对高温作业工人几种水溶性维生素的代谢情况进行研究。VB₁、VB₂、VC由汗、尿中丢失量分别占摄入量的22.11%,26.77%和6.21%。由汗丢失的VB₁、VB₂分别是尿的1.4倍和1.8倍,是高温作业工人的主要丢失途径。汗中VB₁、VB₂、VC的浓度分别为0.059±0.037μg/ml,0.049±0.023μg/ml,0.390±0.211μg/ml。汗中水溶性维生素的浓度可能受机体营养水平的影响。本文结果可为高温作业工人维生素的补充提供理论依据。更多还原

【Abstract】 Losses of several water-soluble Vitamins in workers under high-tomperature environment in Anshan Steel company were detemined. The smount of Vit. B₁, B₁, and C lost in persspiration accounted for 22.11%, 26.77% and 6.21% of their intakes respectively.The losses of Vit. B₁ and B₂ in sweat were 1.4 and 1.8 times higher than these in urine respectively. The results showed that perspiration was the main routine for water-soluble Vitamin losses. The concentration of Vit. B₁, B₂ and C in sweat was 0.059±0.037μg/ml, 0.049±0.023μg/ml, 0.390 ± 0.211μg/ml. It demonstated that the concentrations of water-soluble Vit. were propably influenced by the nutritional, state of human body, that is, the better the nutritional state of human body, the higher the concentration of water-soluble Vit in sweat. The study results misht be useful in considering the water-scluble supplies to workers in high-tomperature conditions.更多还原
