Residents of Delhi woke up recently to a distressing sight: a heavy layer of smog enveloping the city. The air quality has plummeted to alarming levels, with pollution rates soaring 30-35 times above the safe limits set by the World Health Organization (WHO). This annual crisis, which occurs primarily during the winter months from October to January, is exacerbated by a combination of factors including falling temperatures, vehicular emissions, and the burning of crop stubble.
Experts warn that the air quality in Delhi is expected to deteriorate further in the coming days.
According to data from the Swiss Air Quality Index (AQI), pollution levels across multiple areas in Delhi reached a staggering 500 on a recent Wednesday morning. The AQI measures concentrations of particulate matter, specifically PM 2.5, which poses significant health risks as these minuscule particles can infiltrate the lungs and lead to serious diseases.
In terms of air quality ratings, values below 100 are considered satisfactory for breathing. However, readings between 400-500 indicate severe pollution conditions. Satellite cities like Noida and Gurgaon have also reported similar levels of contamination.
The effects of this toxic air extend beyond discomfort; they are impacting daily life significantly. Poor visibility has resulted in numerous flight cancellations and delays. Even NASA has captured images from space showcasing the extensive smog covering northern India and parts of Pakistan.
The health implications are dire. A survey conducted by LocalCircles revealed that 81% of families in Delhi and adjacent areas reported at least one member suffering health issues linked to pollution over the past three weeks. Notably, over one-third of respondents indicated they had purchased cough syrup during this period.
In response to this crisis, the Delhi government has activated its Graded Response Action Plan, which includes banning coal and firewood usage as well as restricting diesel generators for non-emergency purposes. Authorities are also advising residents to remain indoors and utilize public transport in an effort to reduce emissions.
Despite these measures, Delhi remains ranked as the most polluted capital city in 2023 according to Swiss air-quality monitoring data. Furthermore, India is now recognized as the third-most polluted country globally, trailing only behind Bangladesh and Pakistan.
The persistent problem of air pollution in India stems from rapid industrialization coupled with insufficient enforcement of environmental regulations. While the nation has made strides in development over recent decades, inadequate oversight allows factories to neglect pollution-control measures, thus exacerbating environmental degradation.
As authorities grapple with this ongoing challenge, it is imperative for both policymakers and citizens to prioritize sustainable practices and enhance regulatory frameworks to protect public health and improve air quality moving forward.
