Trend Analysis of Sulphur Dioxide in Bangalore & Effectiveness of Control Measures

Abstract

Bangalore is a city in the Indian state of Karnataka. Many public sector businesses and R&D organisations, such as Hindustan Aeronautics Limited, Indian Space Research Organisation, Airbus, Boeing, General Electric (GE), Nokia, Toyota, and others, are housed here. Bangalore is known as India’s ‘Silicon Valley’, as it is home to many information technology (IT) enterprises. It is classified as a ‘non-attainment city’, meaning that pollution levels do not match the Central Pollution Control Board’s (CPCB) criteria. A high-level computer language called PYTHON was used to draw the trends of the air quality data collected over a 15-year period (2004-2019). PYTHON was used to clean, group, sort and aggregate the collected data to obtain the exceedance factor and draw the trend graphs. The policies of the Central Pollution Control Board (CPCB) and the Karnataka State Pollution Control Board (KSPCB) were examined to better understand the pattern. Over the years, the CPCB and the KSPCB have established a number of policies and guidelines, and the success or failure of these policies was examined in order to gain a better knowledge of the control measures. This report lays the groundwork for future policy implementation in other cities.
