Human-produced aerosols such as particle pollution tend to have a smaller radius than aerosol particles of natural origin (such as windblown dust). The false-color maps in the map of distribution of aerosol particles on the right show where there are natural aerosols, human pollution, or a mixture of both, monthly.

The following list of countries by air pollution sorts the countries of the world according to their average measured concentration of particulate matter in micrograms per cubic meter (μg/m 3). The World Health Organization's recommended limit is 10 micrograms per cubic meter, although there are also various national guideline values, which ...

Since the industrial revolution, humans have had an unmistakable impact on Earth -- and it has only accelerated over time.
The World Bank has estimated that welfare losses (premature deaths) and productivity losses (lost labour) caused by air pollution cost the world economy over $8 trillion per year. Air quality is closely related to the Earth's climate and ecosystems globally.
SARS-CoV-2 remained viable in aerosols for 3 hours, with a decrease in infection titre similar to SARS-CoV-1. The half-life of both viruses in aerosols was 1.1 to 1.2 hours on average. The results suggest that the transmission of both viruses by aerosols is plausible, as they can remain viable and infectious in suspended aerosols for hours and ...
The U.S. also exported 11 metric tons of processed foods to other countries in 2022, with Canada and Mexico being the biggest buyers. The overall export value that year exceeded $38 billion.
