      "text": "The Pakistan Air Quality Initiative (PAQI) provides community-driven air quality data to increase social awareness. The World Health Organization (WHO) reports that major cities in Pakistan are as polluted as the world’s most-polluted cities. The air in Pakistan has an annual average of 60 micrograms per cubic meter of air (μg/m³) of PM2.5 particles. That is four-times the safe levels recommended by the National Environmental Quality Standards for Ambient Air by the Environmental Protection Agency in Pakistan (PK-EPA). This air quality may result in serious health effects, aggravating lung and heart diseases and causing respiratory effects in the general population.",
