Air pollution is a serious global problem that affects many countries. According to the data from the World Health Organization (WHO), here is a list of the top 10 most polluted countries in the world in terms of fine particulate matter (PM2.5) levels in 2019:
- Bangladesh : Bangladesh has some of the highest air pollution levels in the world. The main sources of air pollution in Bangladesh are industrial emissions, vehicle exhaust, and the burning of fossil fuels. The air pollution in Bangladesh is a significant public health concern, causing respiratory and cardiovascular diseases, and it's affecting the daily life of millions of people.
- Pakistan : Air pollution in Pakistan is a significant public health concern. It's caused by industrial emissions, vehicle exhaust, burning of fossil fuels, use of pesticides and the burning of crops, this is making it harder for people to breathe and leading to serious health problems.
- India : Air pollution in India is a major public health crisis, with high levels of fine particulate matter and toxic gases in the air. The main sources of air pollution in India are industrial emissions, vehicle exhaust, burning of fossil fuels, and crop burning which is affecting the health of millions of people and leading to respiratory and cardiovascular diseases.
- Nepal : The main sources of air pollution in Nepal are industrial emissions, vehicle exhaust, and the burning of fossil fuels and waste. The high levels of particulate matter and toxic gases in the air are causing respiratory and cardiovascular diseases and affecting the daily life of millions of people.
- Afghanistan : Air pollution in Afghanistan is a significant public health concern, with high levels of particulate matter in the air caused by dust, sand and other natural factors. The air pollution in Afghanistan is also caused by industrial emissions, vehicle exhaust, burning of fossil fuels and agricultural practices such as crop burning, which are leading to serious health problems for many people.
- Bahrain
- Oman
- Qatar
- Saudi Arabia
- United Arab Emirates
Please note that this list is based on PM2.5 levels, which are a measure of the amount of tiny particulate matter suspended in the air. These particulates can come from a variety of sources, including industrial emissions, vehicle exhaust, and burning of fossil fuels. Other forms of pollution such as water pollution and plastic pollution also affect many countries. It's also worth noting that this data is from 2019, and it's important to check for the most recent data to get a current picture of the situation.
