Occurrence of N-nitrosamines in the atmosphere and human health risk: A case study in an urban area of Chuncheon, Gangwon State, South Korea.

This study aimed to investigate the occurrence of eight nitrosamines (NAs) in particulate (PM) and gaseous phases and assess the human health risk associated with these compounds in an urban area of Chuncheon, Gangwon State, South Korea, across four sampling seasons. The findings revealed that the total concentrations of eight NAs measured during the sampling period exceeded the public health recommendation of 0.3 ng/m provided by the Norwegian Institute of Public Health, indicating a potential human health risk from NA exposures.
