Abstract
Algae are often exposed to heavy metal pollution due to the disposal of industrial and domestic wastes into waterways. Many algae growing in metal–polluted environments display an ability to tolerate high concentrations of toxic metals (De Filippis and Pallaghy 1994). In fact, even laboratory cultures of some algae can be acclimated to elevated concentrations of toxic metals (Shehata and Whitton 1982; Kuwabara and Leland 1986; Rai et al. 1991; Twiss et al. 1993). Metal tolerance in algae may be genetic or physiological, and the available reports often do not distinguish between these two different sets of mechanisms. The phrases tolerance and resistance have often been used interchangeably, although the latter phrase may be preferred if ability to withstand high concentrations of metals is genetically fixed.
