Real-Time Evaluation of Air and Water Quality in Urban Areas

Air and water are the most important elements that drive life on earth. Nowadays, the air and water resources are being polluted at a faster rate which poses a serious threat not only to humanity but also to the entire ecosystem. Results from this air and water pollution monitoring study reveal the high amount of particulate matter PM2.5, PM10 suspended in the atmospheric air due to vehicular emissions at a major road and railroad intersections in the Chennai city and Vaniyambadi Town during the month of February 2020. Construction activities are also responsible for the contribution offline and coarse particulate matter load in ambient air. The quality of air is found to get improved during the night time, especially in the residential areas. PM2.5 and PM10 levels are generally found higher in Chennai than in Vaniyambadi. The presence of tannery clusters in and around Vaniyambadi has contributed to the abnormal levels of Total Dissolved Solids TDS in the groundwater. All the data were collected autonomously in real-time using the concept of the Internet of Things IoT. Data collected were stored in a secure server for the use of future analytics. The results are aimed at identifying the hotspots of pollution which would greatly aid in the pollution prevention activities.
