The present study was conducted to evaluate the sensitivity of the Vibrio fischeri bioluminescence inhibition test (Microtox ® assay), and the standard acute Daphnia magna test; using 3 heavy metals, 3 organic pesticides, and their mixtures. In Daphnia tests, either at 24h or 30 min exposure times, the pattern of toxicity order for heavy metals was Cu ˃ Cd ˃ Pb. Chlorpyrifos-methyl was the highest toxic at 24h, while Triazophos was the highest toxic at 30 min exposure times.

“…Bioluminescent bacteria, such as Vibrio fischeri, have been used for environmental monitoring.

“…The effect of adding humic acid upon the toxicity of Cu(II) and Cd(II) to Daphnia pulex was examined (Winner, 1984). Other studies have been done by the use of D. pulex (Cr(VI) and Cd(II)) (Stackhouse and Benson, 1988), Ceriodaphnia dubia (Cu(II)) (Kim et al, 1999), V. fischeri (Cu(II) and Hg(II)) (Alberts et al, 2000), D. magna (Cu(II)) (Kramer et al, 2004), and V. fischeri (Cu(II), Zn(II), and Pb(II)) Tsiridis et al, 2006). In most cases, the presence of DOM and/or humic substance gives a reduction in the toxicity of heavy metal ions due to the complexation of metal ions with humic substance.…”

Effect of the addition of chelator on the acute toxicity of heavy metal ions to freshwater organisms was examined. The Cu(II) complexation ability estimated in this study was in the order: EDTA > NTA > IDA > citric acid, aspartic acid > humic acid, natural organic matters from lignite. Then, the acute toxicity of several heavy metal ions (Cu(II), Zn(II), Pb(II), Cd(II), and As(V)) were evaluated using Daphnia magna in the absence or presence of chelators. The acute toxicity for cationic metal ions greatly decreased when artificial chelators, such as ethylenediaminetetraacetic acid (EDTA) and nitrilotriacetic acid (NTA), were added in the test solution. However, the correlation between toxicity reduction abilities for Cu(II) and the metal complexation ability of these chelators was poor. In addition, the Cu(II) uptake was decreased when EDTA and NTA were added in the test solution. A single logarithmic linearity between the Cu(II) toxicity (EC 50 ) for D. magna and Cu(II) uptake was observed. It is concluded that the addition of chelators affects the complexation ability for heavy metals and metal uptake into the organism, and also the heavy metal toxicity reduction is directly dependent on the uptake of the metal.Keywords: acute toxicity, bioavailability, chelator, Daphnia magna, heavy metals INTRODUCTIONThe ecotoxicity of heavy metal ions in aqueous media has been well studied by the use of many freshwater organisms, and the toxicity may be affected by the presence of chelators which naturally and/or artificially exist in the environment. Various artificial chelators, such as ethylenediaminetetraacetic acid (EDTA) and nitrilotriacetic acid (NTA), are used in many industrial processes and products, and the agents are likely to be contained in wastewaters (Schmidt et al., 2004). There have been several studies about the toxicity of the complexes between metal ions and chelators. Batchelder et al. reported the acute toxicity of complexes formed by EDTA with several heavy metal ions, when a fish, Lepomis macrochirus, was used (Batchelder et al., 1980). Rao examined the effect of the metal chelation upon the toxicity of various heavy metal ions against a water flea, Daphnia magna (Rao, 1985). Sorvari et al. and Sillanpaa et al. have done similar studies using D. magna (Sorvari and Sillanpaa, 1996), a green alga (Pseudokirchneriella subcapitata) (Sillanpaa et al., 2003), and bacteria (Viblio fischeri) (Sillanpaa and Oikari, 1996). In these studies, the toxicity of metal complex is obtained under the experimental conditions in which the concentration of metal ion and that of chelating agent are simultaneously changed. The metal complexes show much less toxicities compared to the corresponding free metal ions. Guilhermino et al. (1997) reported that when an EDTA-containing medium was used in the ecotoxicity test, the toxicity of some metal ions (Cu(II) and Cd(II)) to D. magna became lower than that for a medium without EDTA (Guihermino et al., 1997).
