Sammanfattning

Because of the stratospheric ozone depletion that took place during the last decades of the past century, the effects of ultraviolet radiation on plants, animals, humans and micro-organisms became intensively studied. In this chapter we describe the role of the ozone layer as a radiation shield and various molecular and organismal effects of ultraviolet radiation, with an emphasis on the UV-B band (280-315 nm), which is strongly affected by the ozone content of the atmosphere. Also physiolical protection mechanisms and repair systems are briefly treated.
