ENVIRONMENTAL HEALTH RISK ANALYSIS EXPOSURE TO NITROGEN DIOXIDE (NO2) AND SULFUR DIOXIDE (SO2) ON STREET VENDOR IN AMPERA TERMINAL PALEMBANG 2015

Abstract

Background: Terminal is a location that generates air pollution as a result of transport activity performed. The use of motorized transport will produce a wide range of gases including NO₂ and SO₂. At certain concentrations of NO₂ and SO₂ can have an effect on health disorders for example respiratory problems, throat irritation and eye irritation.

Methods: This study was a descriptive study of environmental health risk analysis method. Eighty four traders were sampled in this study. Simple random sampling was used as sampling technique. The variable used is the concentration of NO₂, SO₂ concentration, Inhalation Rate (R), exposure time, frequency of exposure, duration of exposure, weight, time period average-average, RFC, risk level. Univariate data analysis techniques. And then the data is presented in tabular form and narrative to interpret the data.

Result: The street vendors in Terminal Palembang Ampera has a weight of less than 65.57 kg by 54.8%, exposure time ≤8 hours/day by 54.8%, the frequency of exposure ≤362 days/year amounted to 98.8 %, duration of exposure ≤10 years of 57.1%, intake NO₂ ≤0.00132 mg/kg/day by 50%, SO₂ intake 0.00677 mg/kg/day by 50%, NO₂ RQ>1 at 0%, SO₂ RQ>1 amounted to 11.9%, SO₂ RQ>1 male sex-men by 80%, and SO₂ RQ>1 is derived from the four measurement points by 40%.

Conclution: This research concluded that exposure to Nitrogen Dioxide (NO₂) to street vendors at Terminal Ampera Palembang does not pose a risk, whereas exposure to Sulfur Dioxide (SO₂) provides risk to 10 street vendors in Terminal Ampera Palembang.
