This paper summarizes the formation pathways and mechanisms of important atmospheric secondary pollutants. Acute toxicity of a respiratory irritant exposure is defined by symptom onset within seconds to up 24 hours after a gas exposure. Symptoms, as well as symptom onset, are largely based on the water solubility of the gas, if that gas forms an acid or base when dissolved in the water of the respiratory tract (Kimbell et al. 1993 ). Generally, more ...
