<![CDATA[Lead is a chemical compound that is generally used as an ingredient in gasoline. Lead can control the octane number so as to streamline the combustion process and power. The high octane number of the fuel will reduce the sound of the engine so that the engine performance is good. However, the use of lead also has an increasing negative impact, especially on human health. One type of work that is at risk of being exposed to lead is parking attendants. The purpose of this study was to determine the average lead content in the hair of parking attendants in open and closed spaces. This study used hair samples as bioindicators which were analyzed using an Atomic Absorption Spectrophotometer (AAS) with a wavelength of 217.9 nm. The results showed that the average value of lead levels in the hair of closed space parking attendants was higher than that of open space parking attendants, namely 0.495 ppm. All lead levels found in the hair of parking attendants were <10 ppm so it was categorized that the parking attendants who were the sample of this study experienced low pollution according to the World Health Organization standards.]]>
