Analysis of Exposure Characteristics and Content of Levels of Lead (Pb) in Blood Specimens on the Event of Hypertension in Traffic Police in Kendari City

Abstract

Development and transportation progress can be seen in the increasing number and types of vehicles crossing urban roads. The density of traffic flow is caused by the high volume of cars that are not per the availability of existing roads. The negative impact obtains a high level of air pollution in the city environment due to exhaust gas emissions from motorised.

The elements contained from the emission of hazardous exhaust gases include Pb elements. This study analysed dacteristics of exposure and lead content in blood specimens with the incidence of hypertension in traffic police in the city of Kendari using a survey mix method. Data were collected using a structured questionnaire instrument, sample collection, and laboratory analysis examination. While the approach used is a cross-sectional study and pure experiment.

The population in this study is the traffic police throughout the city of Kendari in charge of regulating the highway, amounting to 78 people. The selected sample is 44 people. The sampling technique used is purposive sampling—data analysis using the Chi-Square test. The laboratory tests showed that the Pb content in the blood of the traffic police ranged from 11.6 – 11.8 g/dl. In ten samples, there was a relationship between complaints of blood lead levels and the incidence of hypertension with a value of <0.05. There was a relationship between stress-related work with the incidence of hypertension with a value of < 0.05, there is a relationship between noise and the incidence of hypertension with a value of < 0.05, and there is no relationship between dust exposure and the incidence of hypertension with a value of > 0.05.
