Air Pollution Index and Inhalation Risk Assessment to Carbon Monoxide and Nitrogen Dioxide to Traders in the bus station

Abstract

In addition to decreasing air quality, carbon monoxide (CO) and nitrogen dioxide (NO2) gases also have a major impact on the deterioration of human health. Air pollution index (API) was investigated as well as the potential health risk from the exposure of carbon monoxide and nitrogen dioxide to traders in Malengkeri bus station, Indonesia. Samples were collected by purposive sampling technique. The results revealed that air pollution index of CO and NO2atthe beginning of the week were 1473.82 and 2.57, respectively. While ontheweekend were 2874.83 and 1.53, respectively. The average risk quotient of acute exposure at the beginning of the week for CO was 0.0036. While ontheweekend was 0.0041. The average risk quotient of chronic exposure at the beginning of the week for NO2was 0.02. While ontheweekend was 0.01. The air pollution index of CO from the beginning until the end of the week could be described as a danger for human health, while for NO2was good. Both average risk quotient of CO and NO2had not exceeded the guideline (>1) and not indicated any noncarcinogenic health risk. However, the male might suffer from the effect compared with female.
