Abstract
We report on the initial results of measurements of the exchange of organic acids and aldehydes between lichens and the atmosphere under controlled cl imate chamber conditions. We found a formic acid deposition to lichens depe nding on thallus water content. Investigation of aldehyde exchange revealed a small and time limited emission of acetaldehyde which is enhanced by ano xic conditions. Formaldehyde emission was never observed.
