The composition of atmospheric aerosols varies with time, season, location, and environment. This affects key aerosol properties such as hygroscopicity and reactivity, influencing the aerosol's impact on the climate and air quality. The organic fraction of atmospheric aerosol emissions often contains surfactant material, such as fatty acids.

Article Synopsis
- There are significant knowledge gaps regarding mercury in the atmosphere, especially in developing regions of the Southern Hemisphere, which hinder effective international regulation and understanding of mercury transport in the environment.
- A study in Dar es Salaam, Tanzania, used passive sampling to measure gaseous elemental mercury (GEM) and identify emission sources, particularly from a municipal waste dumpsite and an e-waste processing facility.
- The results showed elevated GEM concentrations in urban areas, indicating local pollution issues, while soil mercury levels were low and did not correlate with air concentrations, highlighting the need for further research in similar urban settings.
