Measurements show elevated levels of molecular chlorine at the coast of Hong Kong. These high levels of reactive chlorine are explained by the photodissociation of particulate nitrate and subsequent oxidation of chloride.

Model results show that previously unconsidered iodine chemistry can significantly impact ozone loss at the lower edge of the Antarctic stratospheric ozone hole. Iodine also increases the ozone hole area and mass deficit.
