Water quality assessment by ecotoxicological and chemical methods in Magnesia, Greece
The fresh- and seawater quality in Magnesia, Greece, was evaluated in this work, using a combination of bioassays and chemical analytical techniques. The crustacean and the invertebrate saline water shrimp Artemia franciscana were used as test species for monitoring the quality of fresh- and seawater samples respectively. Furthermore, chemical analysis was performed in the samples, for the assessment of pollutants loading. In general, both fresh- and seawater toxicity was low, indicating the good environmental conditions in the area. However, two seawater samples and one freshwater sample, presented high toxicity values, which is in agreement with the chemical measurements. © 2004 Kluwer Academic Publishers.
