“…During the exposure experiments, no food was added. Death of Daphnia magna was defined according to Villegas-Navarro et al (1999) as the inability to swim for more than a few strokes within 15 s after gentle agitation of the test vessel.…”

In this paper, the movement behavior of Daphnia magna was studied as a bio-indicator of organophosphorous pesticide (OP) contamination, using an on-line bio-monitoring method, the Multispecies Freshwater Biomonitor®. A static test of acute toxicity test revealed the 24-h and 48-h LC 50 values (95% confidence limit) for Daphnia magna to be respectively 0.45 μg/l and 0.21 μg/l for dipterex 3.80 μg/l and 0.90 μg/l for malathion, and 1.25 μg/l and 0.38 μg/l for parathion. The behavior strength of Daphnia magna was a sensitive indicator of sublethal OP stress and resulted in significant concentrationresponse relationships for the three OPs. Increasing OP concentration will result in more intensive behavioral responses of Daphnia magna and shorter response time, which could be described by the Stepwise Stress Model (SSM). Therefore movement behavior can be effectively applied in early warning of environment quality by on-line bio-monitoring. The intensive changes in behavior strength of Daphnia magna over a short time follow the SSM concept and can be used as an indicator of early stress response to OP accidental contamination.

“…Porém, isto não significa que o sistema de tratamento empregado entrega um efluente não tóxico para organismos aquáticos. Assim, pode-se dizer que as lagoas de tratamento não são totalmente eficientes quanto à remoção de toxicidade (VILLEGAS-NAVARRO et al, 1999) Com isso, é possível afirmar que um sistema de tratamento pode ser eficiente quanto à remoção de carga orgânica e parâmetros físico-químicos, mas incapaz de remover toxicidade.…”

“…Direct discharge of wastewater to receiving environment causes primary environmental effects such as forming toxic-carcinogenic aromatic amines under uncontrolled anaerobic conditions. It is insufficient to put forward this potential impact on living organisms in aquatic ecosystems by means of physical/chemical analysis 1 . The reason of this is that effluents having complex and toxic effects of usually unspecific contaminants and the potential synergistic or antagonistic effects among them can only be determined through toxicity tests 2 .…”

Nowadays, three methods which target the evaluation of the characteristics of ecotoxicology tests according to aquatic trophic level are well-known, approved methods. In Turkey, the toxicity dilution factor (TDF) method, approved by Turkish Water Pollution and Control Regulation, and Lebistes reticulatus the actual method name that utilizes this animal which is a high level consumer, are used in the assessment of acute toxicity levels of waste waters with different compositions. However; it is not preferred by researchers except statutory obligations due to its disadvantages in implementation. The other method Daphnia magna, which belongs to secondary trophic group, is also widely used. Vibrio fischeri which is based on bioluminescent bacteria is mostly preferred due to ability of giving fast and precise results in acute toxicity assessment tests. In this study, specific to Turkey, it is aimed to compare issues such as experimental process, time, cost, efficiency, repeatability, etc. of tests that take place in the related legislation and standards. In light of all this information, it is determined the insufficient parts about legal regulations related to toxicity in Turkey. It can be suggested that bioluminescence bacteria (V. fischeri), defined all around the world recently with its precision, optimal cost, repeatability features be used in Legal Regulations of Turkey. It is aimed to contribute to scientific literature, this study being the first on suggesting an innovative approach about acute toxicity test in Turkey.
