| 摘 要： | 武汉某蓄电池厂６９名长年接触铅作业工人血铅及相应血尿生化指标测定结果表明：平均血铅含量１．４８±０．６７μｍｏｌ／Ｌ（Ｘ±ｓ），血红蛋白为１２９．０±２５．４ｇ／Ｌ，贫血率为３６．３％；血锌原卟啉为６．６５±３．６５μｇ／（ｇ·Ｈｂ），血δ－氨基酮戊酸脱水酶为５９．２±４９．５ＩＵ／Ｌ，尿δ－氨基酮戊酸为５．６９±４．４４ｍｇ／Ｌ同时发现，作业工人膳食总热能、Ｃａ、ＶｉｔＡ、ＶｉｔＢ２摄入不足，血铅水平与膳食中磷、ＶｉｔＢ１、ＶｉｔＢ２摄入量呈负相关。结合膳食营养素对铅代谢的影响，本文提出了相应的合理膳食建议。

| Abstract: | Across-sectional study on the concentration of blood lead and biochemical alterations in blood and urine of workers occupationally exposed to lead was carried out in a cell-keeping factory. The results showed:that there are Pb:1.48±0.67 μmol/L,Hb:129.0±25.4g/L,ZnPP:6.65±3.65g/g·Hb,δ-ALAD:59.17±49.50IU/L in blood and δ- μALA:5.69±4.44 mg/L in urine;that the blood lead concentration is significant negatively correlated with the daily nutritional content of dietary vitamin B1,B2intake. These results suggest that a rational dietary guideline is necessary for the workers to prevent lead-induced biochemical alteration. |
