Abstract
Bioassays approved by the State Standard (GOST) (Daphnia magna and Cer iodaphnia affinis) and new bioassays (the unicellular protozoan Parame cium caudatum and luminescent bacteria Photobacterium phosphoreum) wer e used to monitor the quality of purified municipal and industrial was tewaters (from the city of Krasnoyarsk and an integrated pulp-and-pape r mill). It was shown that all invertebrates tested were similar in th eir sensitivity to pollution, and their sensitivities were higher than that of luminescent bacteria. However, unicellular organisms can be u sed successfully for analysis of water quality if instrumental methods are employed. This analysis is by several orders of magnitude more ra pid than GOST bioassays and produces more reliable results.
