Why dust is a pollutant?

Dust is considered a pollutant because it consists of fine particles that can be suspended in the air, leading to respiratory issues and other health problems when inhaled. It can carry harmful substances, including heavy metals, allergens, and pathogens, which can exacerbate existing health conditions. Additionally, dust can reduce air quality and visibility, impacting both environmental and human health. Its presence in the atmosphere can also contribute to climate change by affecting sunlight absorption and precipitation patterns.
