195-199. Use has been made of data collected over a number of years from workers exposed to a lead hazard in a motor-car factory. The correlations between various parameters of lead absorption and lead intoxication were computed, including blood and urine lead concentrations, urinary coproporphyrin, ALA and PBG concentrations, and haemoglobin concentration. In all, 15 correlation coefficients were calculated, of which only six showed a statistically significant result (i.e., P<0·05). These six were blood lead and urine lead (r = 0·38, P<0·001), urine lead and coproporphyrin (r = 0·42, P<0·001), urine lead and ALA (r = 0·43, P<0·001), coproporphyrin and ALA (r = 0·75, P<0·001), ALA and PBG (r = 0·49, P<0·001), and urine lead and PBG (r = 0·19, P<0·05).
195 - 199. 利用了多年来从一家汽车工厂中接触铅危害的工人那里收集的数据。计算了铅吸收和铅中毒的各种参数之间的相关性，包括血铅和尿铅浓度、尿中粪卟啉、δ-氨基-γ-酮戊酸（ALA）和卟胆原（PBG）浓度以及血红蛋白浓度。总共计算了15个相关系数，其中只有6个显示出具有统计学意义的结果（即P<0.05）。这6个分别是血铅和尿铅（r = 0.38，P<0.001）、尿铅和粪卟啉（r = 0.42，P<0.001）、尿铅和ALA（r = 0.43，P<0.001）、粪卟啉和ALA（r = 0.75，P<0.001）、ALA和PBG（r = 0.49，P<0.001）以及尿铅和PBG（r = 0.19，P<0.05）。
