Continuous biomonitoring systems for detection of toxic levels of water pollytants

ABSTRACT The most important continuous biomonitoring systems which are presently being used for the assessment of water quality are discussed briefly. Special attention is given to their indicator value as well as to observation methods which may expand their perceptive faculty. It is concluded that a proper water quality assessment can not rely only upon the use of biological monitoring systems. They should be seconded by adequate multidetectional chemical monitoring methods.
