Air pollution is responsible for many health problems in the urban areas. Of late, the air pollution status in Delhi has undergone many changes in terms of the levels of pollutants and the control measures taken to reduce them. This paper provides an evidence-based insight into the status of air pollution in Delhi and its effects on health and control measures instituted. The urban air database released by the World Health Organization in September 2011 reported that Delhi has exceeded the maximum PM10 limit by almost 10-times at 198 μg/m3. Vehicular emissions and industrial activities were found to be associated with indoor as well as outdoor air pollution in Delhi. Studies on air pollution and mortality from Delhi found that all-natural-cause mortality and morbidity increased with increased air pollution. Delhi has taken several steps to reduce the level of air pollution in the city during the last 10 years. However, more still needs to be done to further reduce the levels of air Air pollution Delhi, control measures, health
Pollution refers to the contamination of the earth's environment with materials that interfere with human health, quality of life or the natural functioning of the ecosystems. The major forms of pollution include water pollution, air pollution, noise pollution and soil contamination. Other less-recognised forms include thermal pollution and radioactive hazards. It is difficult to hold any one particular form responsible for maximum risk to health; however, air and water pollution appear to be responsible for a large proportion of pollution related health problems.

Answer:
COVID-19 has cast a global gloom by causing severe damage to health, the economy and general societal well-being. Temporarily, clean air provides some respite while a major portion of the world population remains indoors, abiding by social distancing norms. In India too, after many years, the blue sky can be spotted in normally hazy regions, as corroborated by satellite images, pollution data, and social media posts. However, the present air quality (AQ) improvement in India dwells in irony. Amidst the devastating COVID-19 crisis, it is neither the time to rejoice clean air nor would one want air quality to improve this way in the future.
Moreover, this clean air phase is short lived and temporary. Some experts are concerned that environmental restrictions will be loosened to bounce back from the COVID-19 related economic losses. As a result, achieving better air quality may be harder than ever when the global crisis ends. Poor AQ, in fact, makes people more vulnerable to respiratory diseases, like the one caused by COVID-19. Some of the underlying conditions that make certain people “high risk” for coronavirus complications (asthma, COPD) are caused or made worse by exposure to air pollution. Poor AQ increases societal vulnerability in many ways.

Nevertheless, the ongoing episode could be an important opportunity to identify the key drivers of air pollution in regional airsheds. Scientists will inevitably seize the curfew window to understand background levels of air pollutants when the emissions from most important sectors, including transport and industry, have significantly decreased. For others, it could be a chance to make a strong demand for clean air from the authorities. The challenge to sustain the good air days after the COVID-19 lockdown can be mitigated by tapping into the unique aspects of air quality while the air is still breathable. It is also the time to shift the focus from analysing pollution in the big cities and capture a pan India air quality status.
