| Zusammenfassung |
| Air quality in many cities is deteriorating due to rapid urbanization and motorization. In the
past, most of the health impacts studies in the urban areas have considered stationary air
quality monitoring station data for health impact assessment. Since, there exist a spatial
and temporal variation of air quality because of rapid change in land use pattern
and complex interaction between emission sources and meteorological conditions,
the human exposure assessment using stationary data may not provide realistic
information. In such cases low cost sensors monitoring is viable in providing both
spatial and temporal variations of air pollutant concentrations. In the present study an
attempt has been made to use low cost sensor for monitoring the personal exposure
to the two criteria pollutants CO and PM2.5 at 3 different locations of Chennai
city. Maximum and minimum concentrations of CO and PM2.5 were found to be
5.4ppm, 0.8ppm and 534.8μg/m3, 1.9μg/m3 respectively. Results showed high
concentrations near the intersection and low concentrations in the straight road. |
