Short summary

Gas-particle partitioning is critical to govern the environmental fate of atmospheric pesticides, yet it remains poorly studied. Our work investigated atmospheric pesticides in gas and particulate phases in the North China Plain and their gas-particle partitioning mechanism. Results revealed pesticides in particulate phase were dominant. Absorption is the main mechanism of gas-particle partitioning, indicating atmospheric pesticides were absorbed into the interior organic film of particles.
