对某电石厂电石炉车间和某橡胶厂硫化车间的气象条件及其高温作业工人的夏季膳食进行了调查。结果表明,电石炉车间炉前岗位属于干热型高温作业;橡胶硫化岗位属湿热型高温作业。两个车间高温作业工人平均每人每日热量为标准供给量的72.7％;蛋白质为69.6％、糖类为72.7％、脂肪为60.3％;钙64.5％、铁96.5％;维生素A、B_1、B_2、C和PP各为72.8％,50.5％,33.0％,60％和79.9％。高温作业工人夏季各种营养素供给量较标准供给量普遍偏低,尤其VB_1、VB_2和VC的供给量不足更为明显。因此,我们认为加强高温作业工人的膳食营养的同时,给予有效的强化食品对补充一些营养素不足是很有必要的。
A calcium carbide plant calcium carbide furnace workshop and a rubber plant curing workshop meteorological conditions and its high temperature workers in the summer diet were investigated. The results show that the calcium carbide furnace in front of the furnace is a hot and dry high-temperature jobs; rubber curing station is a hot and humid type of high temperature operation. The daily heat per worker per day for the two workshop workers was 72.7% of the standard supply; the protein was 69.6%; the carbohydrate was 72.7%; the fat was 60.3%; the calcium was 64.5%; the iron was 96.5%; the vitamins A, B_1, B_2 , C and PP were 72.8%, 50.5%, 33.0%, 60% and 79.9% respectively. In summer, the supply of various nutrients to high-temperature workers is generally lower than the standard supply, especially the insufficient supply of VB_1, VB_2 and VC. Therefore, we think that it is necessary to provide effective fortified foods to supplement some nutrients when strengthening the dietary nutrition of workers in high temperature.
