Garages and auto-repair workshops may be polluted with other heavy metals besides lead. Blood of autoworkers with high lead content was analysed for cadmium, chromium, copper manganese, nickel, ALAD activity and carboxyhaemoglobin level. Cadmium and copper levels in blood of autoworkers were comparable with those of the control subjects while chroimium and nickel levels were significantly higher (P less than 0-01 for both metals), and scattered raised values of manganese were found. There was no significant mutual correlation between levels of various heavy metals determined in whole blood. High copper levels were slightly related to decreasing ALAD activity (P less than 0-1). Nineteen per cent of autoworkers were found to have an abnormally blood level of carboxyhaemoglobin. The amount of particulate heavy metal in autoworkshop air was not related to biochemical abnormalities found in the autoworkers. Various sources of pollution of these heavy metals in autoworkshops are discussed.
除铅之外，车库和汽车修理车间可能还受到其他重金属污染。对血铅含量高的汽车工人的血液进行了镉、铬、铜、锰、镍、δ-氨基-γ-酮戊酸脱水酶（ALAD）活性及碳氧血红蛋白水平的分析。汽车工人血液中的镉和铜水平与对照组相当，而铬和镍水平显著更高（两种金属均P<0.01），且发现锰值有散在升高。全血中测定的各种重金属水平之间无显著的相互相关性。高铜水平与ALAD活性降低略有相关（P<0.1）。发现19%的汽车工人碳氧血红蛋白血液水平异常。汽车修理车间空气中的颗粒重金属量与汽车工人中发现的生化异常无关。文中讨论了汽车修理车间这些重金属的各种污染来源。
