Περίληψη:
Significant portions of European cities’ population are still exposed to
levels of air pollution deemed harmful by the World Health Organization.
Given the high impact of air pollution both on human health and the
economy, numerous low-cost electrochemical sensor monitoring systems are
being installed. The market is forced to develop new air quality
monitoring systems to meet the needs of providing forecasting services
based on advanced technologies and protocols that utilize certain
characteristics such as high accuracy, real-time monitoring, daily and
yearly statistics, data access from both experts and simple users with
the use of low-cost equipment. In this study, conducted in Athens,
Greece, a comparison is attempted between the findings from a low-cost
electrochemical sensor device and those of a static, fixed site
measurement monitoring station; this comparison is based on the data
quality and Air Quality Index (AQI) concerning data accuracy and quality
on adverse health effects due to air pollution. With regard to the
prediction of different AQI intervals, TPR ranges from 35.2% up to
100.0%, FPR from 0.0% up to 36.1% and FNR from 0.0% up to 38.1%.
The outcome of this study reveals flexible and affordable alternatives
adopted during the evaluation and calibration of low-cost gas sensors
for monitoring.
