  "account": "India's air pollution monitoring systems were overwhelmed this week by a toxic smog so severe that it exceeded their upper measurement limits, according to regulators. This revelation came after opposition politicians accused authorities of intentionally allowing gaps in official readings for several hours overnight Sunday into Monday, just as pollution levels surged due to Diwali celebrations. New Delhi, already one of the world's most polluted capitals, faced a significant rise in pollution levels during the festival. The missing readings meant that the official data did not accurately reflect the full extent of the pollution at its worst. Both the Aam Aadmi Party and the Congress party have criticized the government for allegedly manipulating data during this critical period. The Central Pollution Control Board (CPCB) has dismissed these accusations, stating that the gaps in data were due to the limitations of their measurement instruments rather than a deliberate attempt to conceal pollution levels. Particulate matter analysers, which were installed as part of the National Air Quality Index in 2015, were calibrated to measure concentrations of up to 1,000 micrograms per cubic metre. However, the WHO recommends a daily maximum of only 15 micrograms per cubic metre for PM2.5 particles. When monitoring resumed around eight hours after the fireworks peak, readings in Mandir Marg locality reached 879 micrograms per cubic metre, which is more than 58 times the WHO daily limit. Despite the extreme pollution levels, officials emphasized that the lack of data does not mean that pollution is not present.",
