Analisis Risiko Kesehatan Paparan Gas Nitrogen Dioksida (No2) pada Petugas Parkir di Basement Plaza Andalas

Abstract

<p>Nitrogen dioxide (NO<sub>2</sub>)is a gas that is poisonous reddish brown and very pungent smell like sour nitrat. Emission from vehicle of concentration NO<sub>2</sub> reach 78,8 ppm, this result means so dangerous to health, especially that emission in door, like basement. The porpuse this study was to analyze the health risks of nitrogen dioxide exposure to the parking attendant Plaza Andalas Basement.
