对上海50名、日本(东京、京都、仙台)72名城市中非职业性接触妇女摄入的食物、米饭及血中铅、镉量以湿法灰化,石墨炉原子吸收仪进行测定,以资比较。每天从食物和米饭中摄取铅的几何均数值在上海妇女分别为170和05μg,日本妇女为116和14μg,而相应的镉摄取量在上海妇女分别为61和20μg,日本妇女为321和105μg。上海和日本妇女血铅浓度分别为790和321μg/L,血镉浓度分别为118和192μg/L,即上海妇女从食物摄入的铅量和血铅高于日本妇女,而镉则相反。结果表明目前的铅、镉摄入量对妇女健康不会造成危害,但日本妇女血镉浓度竟为WHO、美国NIOSH、ACGIH推荐的职业性接触的生物限值(血镉5μg/L)的384%,应于重视。文中还对两种金属元素的摄入途径、受土地和空气污染的影响作了探讨
The food, rice, and blood lead and cadmium intake in 50 Shanghai and 72 cities in Tokyo (Tokyo, Kyoto, and Sendai) were determined by wet ashing and graphite furnace atomic absorption spectrometry. Comparison. Daily lead intake from food and rice geometric mean value in Shanghai women are 170 and 05μg, Japanese women 116 and 14μg, while the corresponding intake of cadmium in Shanghai women were 61 And 20μg, Japanese women were 321 and 105μg. The blood lead concentrations of Shanghai and Japanese women were 790 and 321μg/L, and the blood cadmium concentrations were 118 and 192μg/L, respectively. That is to say, the amount of lead and blood lead from food intake in Shanghai women was higher than that in Japan. Women, while cadmium is the opposite. The results show that the current lead, cadmium intake will not cause harm to the health of women, but the Japanese women’s blood cadmium concentration went so far as WHO, US NIOSH, ACGIH biological limits recommended occupational exposure (blood cadmium 5μg / L) 38 4% should be given due attention. The paper also discusses the ingestion routes of two metal elements and the impact of land and air pollution.
