Abstract


The forest and land fire situation in Sumatra have led to a haze disaster that contain harmful particulate matter exposing Pekan-baru population. Number of studies concerned with associations between respiratory and cardiovascular health effects and exposure to fine fractions of particulate matter (PM2.5) on polluted air have been reviewed by Kim [1]. Although studies have proven signifi-cance difference of health effect due to haze, currently there is no study to estimate the potential health risk to population exposed to haze in Pekanbaru. This study aims to estimate the risk of PM2.5 in ambient air during haze period that exposed Petrol-pump officers. The risk magnitude is represented by Risk Quotient (RQ) that determined by comparing the PM2.5 exposure intake with exposure dose-response of the workers using the Environmental Health Risk method from The International Programme on Chemical Safety (IPCS). Intake value is generated based on the concentration of PM in the environment, individual activity patterns and anthropo-metric values. Concentration of PM2.5 was using secondary data generated by real-time PM measurement for Pekanbaru. The activity patterns and anthropometric values were collected using questionnaire to 20 Petrol-Pump Officers from 5 different gas stations in Pekanbaru. The calculation of lifetime risk showed that Petrol-Pump Officers who were exposed longer since 2015 haze period, has four times greater health risk compared to those who are just exposed in 2019. Petrol-Pump Officers who just got exposed to PM2.5 in 2019 has RQ ≤ 1, hazard was not a threat - however risk still need to be maintained under 1. While RQ for PM2.5 exposure to Petrol-Pump Officers who has worked since 2015 is > 1, means PM2.5 in haze that exposes Petrol-Pump Officers cause the adverse health effects and the risk needs to be managed.
