Passive Sampler for Measurements of Atmospheric Nitric Acid Vapor (HNO3) Concentrations

Passive Sampler for Measurements of Atmospheric Nitric Acid Vapor (HNO3) Concentrations

Nitric acid (HNO3) vapor is an important nitrogenous air pollutant responsible for increasing saturation of forests with nitrogen and direct injury to plants. The USDA Forest Service and University of California researchers have developed a simple and inexpensive passive sampler for monitoring air c...
