Epidemiological studies on metal levels in blood were carried out. Evidence suggested the existence of a different trend in serum-iron levels in relation to blood lead levels in nonoccupationally exposed males (negative trend) and females (positive trend). There was a positive relation between blood lead levels and blood manganese levels in children and occupationally exposed male workers. Blood metal levels increased with age in young children. There was evidence for an influence of socioeconomic class on blood lead levels in children. A direct and an indirect effect of smoking was found on blood lead levels and on the activity of delta-aminolevulinic acid dehydratase activity in erythrocytes in adult nonoccupationally exposed females.
开展了关于血液中金属水平的流行病学研究。有证据表明,在非职业暴露的男性(呈负相关趋势)和女性(呈正相关趋势)中,血清铁水平与血铅水平存在不同的趋势。在儿童和职业暴露的男性工人中,血铅水平与血锰水平呈正相关。幼儿的血金属水平随年龄增长而升高。有证据表明社会经济阶层对儿童血铅水平有影响。在成年非职业暴露女性中,发现吸烟对血铅水平以及红细胞中δ-氨基乙酰丙酸脱水酶的活性有直接和间接影响。
