Most Polluted City In The World 2023: Air pollution is a critical global environmental issue that poses significant health risks to people living in urban areas. The World Health Organization (WHO) estimates that millions of premature deaths occur each year due to the harmful effects of polluted air. In this comprehensive guide, we will explore the top 10 most polluted cities in the world for the year 2023. We will examine the causes and consequences of their poor air quality, as well as delve into the concept of the Air Quality Index (AQI) and its categories of health impacts.
Overview Of Air Pollution – Most Polluted City In The World 2023:
Air pollution is a complex problem caused by the release of harmful substances into the atmosphere. These substances, known as air pollutants, can come from various sources, including industrial emissions, vehicle exhaust, agricultural activities, and household combustion. When these pollutants accumulate in the air, they can have detrimental effects on human health, ecosystems, and the overall quality of life.
What is the Air Quality Index (AQI)?
The Air Quality Index (AQI) is a standardized measurement used to assess the quality of the air in a specific region. It provides a simple way to understand the level of air pollution and its potential health impacts on a given day. The AQI takes into account several key pollutants, including particulate matter (PM2.5 and PM10), nitrogen dioxide (NO2), sulfur dioxide (SO2), ozone (O3), and carbon monoxide (CO).
AQI Categories And Health Impacts:
The AQI is divided into several categories, each associated with specific health impacts:
- Good (0-50): Air quality is satisfactory, and there is minimal risk to health.
- Satisfactory (51-100): Air quality may cause minor discomfort to sensitive individuals.
- Moderately Polluted (101-200): Air quality may cause breathing discomfort for people with respiratory conditions and heart disease
- Poor (201-300): Air quality may cause breathing discomfort to sensitive individuals and can have more severe health effects with prolonged exposure.
- Very Poor (301-400): Air quality may lead to respiratory illness and serious health impacts even in healthy individuals.
- Severe (401-500): Air quality poses a severe risk to health, and everyone may experience more pronounced health effects.
