Workers of two chemical plants exposed to chlorobenzene were examined for actual nutrition and effects of the treatment and prophylactic diet on the food status. Investigation of the actual nutrition has demonstrated that the energy value of the daily diets approaches the magnitudes established for the given occupational and age group whereas the daily distribution of food with respect to the caloric value and alimentary substances does not correspond to the hygienic standards. The treatment and prophylactic diets developed for the workers were also characterized by disproportion between the dietary components. As compared to the control group, the workers exposed to chlorobenzene demonstrated a lower content of total glutathione in blood plasma. The majority of the workers manifested ascorbic acid deficiency. In accordance with the study of the coefficients of the activation of erythrocytic enzymes, it may be concluded that the workers placed on the treatment and prophylactic diet are better provided with vitamins B1, B2 and B6 than the workers of the housing and communal services. Thirty percent of the workers showed vitamin B6 deficiency. This may have an adverse action on the resistance to industrial substances conjugating with glutathione. The rate of vitamin B1 deficiency was also fairly high, whereas in the workers of one of the plants the magnitude of the TDP-effect appeared higher than normal.
对两家接触氯苯的化工厂工人的实际营养状况以及治疗性和预防性饮食对其饮食状态的影响进行了检查。实际营养状况调查表明，日常饮食的能量值接近为特定职业和年龄组设定的数值，然而，食物在热量值和营养物质方面的每日分配不符合卫生标准。为工人制定的治疗性和预防性饮食在饮食成分之间也存在不均衡。与对照组相比，接触氯苯的工人血浆中总谷胱甘肽含量较低。大多数工人表现出抗坏血酸缺乏。根据对红细胞酶激活系数的研究，可以得出结论，接受治疗性和预防性饮食的工人比住房和公共服务部门的工人摄入了更多的维生素B1、B2和B6。30%的工人存在维生素B6缺乏。这可能对与谷胱甘肽结合的工业物质的抵抗力产生不利影响。维生素B1缺乏率也相当高，而在其中一家工厂的工人中，转酮醇酶效应的幅度高于正常水平。
