Chromium is an essential trace element found in soil, water, air, and in the biosphere. It is the fourth most common element in the earth's crust, mostly used to manufacture stainless steel and other alloys. Chromate allergy is not uncommon and its prevalence rate is reported to be 6%. Once developed, it tends to persist for a long time. Chromate is present in most of the dietary items. Chromate content in food often varies considerably from place to place. However, certain foods are routinely high in chromate content. Chromate in the diet of a chromate-sensitive person can provoke dermatitis. Careful selection of food with relatively low chromate concentration can bring a reduction in the total dietary intake of chromate per day. This can influence outcome of the disease, especially chronic vesicular hand eczema due to chromate sensitivity, and can benefit a chromate-sensitive patient.
铬是一种存在于土壤、水、空气和生物圈中的必需微量元素。它是地壳中第四常见的元素,主要用于制造不锈钢和其他合金。铬酸盐过敏并不罕见,据报道其患病率为6%。一旦发生,往往会持续很长时间。大多数饮食中都含有铬酸盐。食物中的铬酸盐含量因地点不同而有很大差异。然而,某些食物的铬酸盐含量通常较高。对铬酸盐敏感的人的饮食中的铬酸盐会引发皮炎。仔细选择铬酸盐浓度相对较低的食物可以减少每天饮食中铬酸盐的总摄入量。这会影响疾病的结果,尤其是因铬酸盐敏感引起的慢性水疱性手部湿疹,并且对铬酸盐敏感的患者有益。
