Currently, Delhi is the most polluted city in the world. This is due to the fact that the government has failed to properly address the pollution problem in the city. There are many factors that contribute to the pollution. These include the lack of proper sanitation facilities, lack of public transport, and the pollution caused by factories. This is not a new problem and has been a major issue for the city since the beginning of the twentieth century. However, it is becoming a much more serious issue with the passage of time. The government has started making efforts to address this problem, but these efforts have not been effective.
Earlier this month, hundreds of people flocked to the streets of Delhi to protest the growing pollution levels in the city. It’s a political issue in India – city dwellers are important constituents for various parties.
The National Clean Air Programme is a government initiative that aims to reduce particulate matter by 20-30 percent by 2024. But, the Delhi government has failed to control pollution sources.
The World Health Organisation ranks Delhi as the world’s most polluted big city. The haze in Delhi is toxic and contains high levels of nitrogen oxide, carbon monoxide, sulfur dioxide, and other pollutants. It also exceeds World Health Organisation limits for annual exposure.
Amongst the top 10 most polluted cities in the world, Faridabad is ranked second by the World Health Organisation (WHO) report. The report states that the annual average PM 2.5 level of Faridabad stands at 172 micrograms per cubic metre.
Faridabad is a major industrial hub in Haryana. The city produces a variety of products such as henna, tyres, motorcycles, air conditioners and switch gears. Some of the sources of pollution in the city are vehicular emissions, construction dust and municipal solid waste burning.
Earlier, Faridabad had an annual average PM2.5 level of 106 ug/m3 and Delhi had an average PM2.5 level of 109 ug/m3. The government is taking measures to control the pollution levels in Faridabad and Delhi. The state government has a detailed action plan to contain pollution in the entire state.
Located in Northern China, Beijing is the capital city of the People’s Republic of China. It has a population of over 21 million people.
In addition to its massive population, Beijing’s air pollution is largely due to the burning of coal to produce electricity. There are a number of coal burning factories located in the outskirts of Beijing and neighboring cities.
Although the city has been improving its air quality in recent years, Beijing still ranks among the top polluted cities in the world. The World Health Organization (WHO) estimates that nine out of ten people worldwide breathe unsafe polluted air on a regular basis.
Several studies have shown that the air in Patna is extremely polluted. In fact, Patna’s air quality is higher than the World Health Organization’s (WHO) recommended standard of 10 micrograms of PM2.5 per cubic metre of air.
Patna is a congested city with dozens of sites that contribute to air pollution. The air quality in Patna has been deteriorating over the past two years. In addition to vehicular emissions, poor management of particulate pollution at construction sites also contribute to the city’s poor air quality.
The National Clean Air Program is a central government initiative to fight air pollution in India. The program aims to improve air quality in non-attainment cities, including Patna. However, progress in the program has been slow.
Located in eastern Henan province, Shangqiu is a central city. It is at the junction of a number of major railway lines. The city is traditionally a farming and manufacturing hub.
According to the World Health Organisation, air quality is defined by PM2.5 particles, which are less than 10 microns in diameter. This particulate matter is more likely to become airborne in wind, and it can affect people’s health.
In the study, the total concentrations of six pollutants were 23 ug/m3. The highest concentration of PM10 was 151 ug/m3, followed by CO at 600 ug/m3. The concentrations of tropospheric NO2 were a bit higher, at 35.5 ug/m3.
The study area included 10 mega-cities in China. Among these were Beijing, Tianjin, Hebei, Guangzhou, Shenzhen, Chengdu, Harbin, and Weinan. The cities’ total population ranged from ten million to thirty million.
Despite the growth and development of Lagos, pollution remains a serious problem. It is estimated that over 30, 000 people die annually due to air pollution in Lagos.
The World Bank and the International Finance Corporation (IFC) have launched a “Breath Better Bond” to address air pollution in Lagos. The bank is offering to work with the Lagos State government to improve air quality.
Air pollution is estimated to cost the nation more than a billion dollars each year. A World Bank study found that more people die from air pollution in Lagos than from HIV/AIDS, malaria, and chronic obstructive pulmonary disease.
