[Multiple analysis of lead concentration in the air and renal function of lead exposure workers].
OBJECTIVE
To determine the lead concentration in the air (pbA) at the workplace and the renal function of lead exposure workers.


METHODS
The lead concentration in the air of 11 printing plants, 4 smelteries and 2 lead mines were measured. Screening urinalysis was performed in 1190 long term lead exposed workers with urine sugar, protein and sigements. It one of the three was abnormal, the workers were given examination of renal function. The relationship between pbA and renal function were confirmed by mutiple linear.


RESULTS
The concentrations of pbA in the printing plants, smelteries and lead mines were 0.07 mg/m3, 0.26 mg/m3 and 0.66 mg/m3 respectively. Altogether 157 cases had one and more abnormal renal function. The correlation of concentration PbA in the workplace and the renal function of lead exposure workers was shown (R = 0.894, P < 0.001, R2 = 0.799). The correlation coefficient of skewness of showed that PbA and Bpb. Upb. Bun Scr Usug. Ubeta2MG were positively correlated (P < 0.01 approximately 0.001); Ccr was negatively correlated (P =0.05). Upro, UNAG and Ualb were nonsignificant.


CONCLUSIONS
The lead concentration in the air at the workplace is related to the renal functions of lead exposure workers. It is important to decrease the lead environment and to prevent renal damage.
