CORRELATION OF LEAD LEVEL (Pb) IN AIR AMBIENCE WITH THE NUMBER OF SPERM CELLS IN GAS STATION MEN’S OFFICERS IN PEMATANGSIANTAR IN 2019

Background: Lead (Pb) is one of the dangerous air pollutants that contain a lot of vehicle fuel. Reports from three gas station locations in Pematang Siantar City are gas stations with gas station operating time for 24 hours so that various types of vehicles require a lot of fuel to fill fuel at this gas station. The purpose of this study was to analyze the relationship of lead levels (Pb) with sperm cell counts in male gas station officials in the city of Pematangsiantar in 2019. Materials and Methods: Design an observational analytic study using Cross Sectional. The population is male gas station officials who issue 14,211,205 gas stations, 14,211,206 gas stations and 14,211,211 gas stations as many as 36 people. The sample uses a total population. Data analysis used univariate and bivariate. Result: The results of the study with the chi-square test showed that the sig value of the variable lead content in ambient air = 0.007, working time = 0.002, working time = 0.003 and the use of PPE = 0.016. Conclusion: There is a significant relationship between lead levels, length of work, working time and use of PPE and sperm counts for male gas station officers in Pematangsiantar City in 2019.
