The recent development of a non-intrusive photothermal deflection (PD) instrument allows the quantitative detection of local ammonia concentrations in air to be measured continuously, sensitively and fast. Ammonia is vibrationally excited by an infra

Ethane is produced in plants after lipid peroxidation of the cell membrane. This process can for example be initiated by ambient SO2 and results in the death of the cell. Ethane has proven to be a reliable indicator of this process [1]. A PA monitor
