ABSTRACT

Chlorophyll a fluorescence emission analysis of photosystem II from the photosynthetic apparatus of terrestrial and aquatic plants and algae makes possible to characterize the effects and modes of action of different kinds of environmental stress (temperature, drought, high irradiance, salinity, flooding), severalwater pollutants such as heavy metals, herbicides, detergents, and a variety of air pollutants, as well. It may be of great help for identification of toxic pollutants and their sources. In addition, this method of analysis can to be applied to plants and algae in situ, and in vivo or to isolated chloroplasts, is not invasive neither destructive and it is a fast and sensitive technique.
