The significance of the determination levels of blood lead, cord blood lead and colostrum lead in pregnant women with exposuring in lead area

ObjectiveTo study the significance of the determination levels of blood lead, cord blood lead and colostrum lead in pregnant women with exposuring in lead area.

MethodsForty-five pregnant women living around the electronic waste recycling field were prospectively selected, and set as the observation group.The levels of maternal blood lead, cord blood lead and milk lead in observation group were detected.Forty puerpera living around no high lead exposure area were set as the control group.The levels of maternal blood lead, cord blood lead and milk lead, and neonatal status were compared between two groups.

ResultsThe study in 39 cases of the observation group and 38 cases of the control group were completed.The neonatal body mass in observation group was significantly lower than that in control group(P < 0.05), and the difference of the neonatal body length between two groups was not statistically significantly(P>0.05).The levels of maternal blood lead, cord blood lead and colostrum lead in observation group were significantly higher than those in control group(P < 0.01).

ConclusionThe women exposuring in high lead environment during pregnancy may lead to fetal lead exposure, and the high foremilk lead may result in the lead exposure during lactation.Therefore we should improve lead prevention work for women living around the lead exposure environment.
