- •
This work compares atmospheric aerosols collected at an urban and a boreal forest site.
- •
Gas/particle partitioning of carboxylic acids and organosulfates is investigated.
- •
Potential artifacts associated with sampling of atmospheric aerosols are evaluated.
- •
Different gas/particle partitioning of carboxylic acids observed at urban and boreal forest site.
- •
Filter adsorption and conversion of semi-volatiles result in biased particle concentrations.
