“…However, activity pattern tests seem less sensitive than either chronic LOEC tests or avoidance-attractance tests for metals. Scarfe et al (1982) showed that copper (100 pg 1-r) elicited hyperactivity in sheepshead, Archosargus probatocephalus, and hardhead catfish, Arias feZis, but had little effect (except perhaps hypoactivity) on Atlantic croaker, Micropogon andulatus, and no effect on pinfish, Lagodon rhomboides. Steele (1983) demonstrated that copper concentrations of 5 to 50 pg 1-l caused hypoactivity in hardhead catfish but that concentrations of 100 and 200 pgl-l caused hyperactivity.…”

SynopsisBehavioral toxicity tests, if properly designed, can be used in conjunction with standard acute lethality tests, chronic full or partial life cycle tests, and early life stage toxicity tests to add ecological realism to toxicant assessments and the regulations made as an outgrowth of these assessments. Changes in certain fish behaviors, especially cough rate and avoidance reactions, are very sensitive indicators of sublethal exposure to metals. Other tests involving predator avoidance, feeding behavior, learning, social interactions, and a variety of locomotor behaviors show promise but have been insufficiently studied to judge their sensitivity or utility. No behavioral tests have been standardized and few have been verified in the field. We discuss the behavioral tests that have been used with metals, examine their sensitivity compared with standard laboratory toxicity tests, and assess the potential ecological significance of the behavioral changes observed.

“…The Microtox assay is considered an accurate and reliable screening method and has good correlations to conventional standard fish testing procedures [22]. The Microtox assay measures the acute toxicity of a sample to the bacterium Vibrio fischeri (earlier referred to as Photobacterium phosphoreum) and the assay using D. magna measures acute immobilization [28][29][30][31].…”

Toxic hazard and chemical analysis of leachates from furfurylated wood

The furfurylation process is an extensively investigated wood modification process. Furfuryl alcohol molecules penetrate into the wood cell wall and polymerize in situ. This results in a permanent swelling of the wood cell walls. It is unclear whether or not chemical bonds exist between the furfuryl alcohol polymer and the wood. In the present study, five different wood species were used, both hardwoods and softwoods. They were treated with three different furfurylation procedures and leached according to three different leaching methods. The present study shows that, in general, the leachates from furfurylated wood have low toxicity. It also shows that the choice of leaching method is decisive for the outcome of the toxicity results. Earlier studies have shown that leachates from wood treated with furfuryl alcohol prepolymers have higher toxicity to Vibrio fischeri than leachates from wood treated with furfuryl alcohol monomers. This is probably attributable to differences in leaching of chemical compounds. The present study shows that this difference in the toxicity most likely cannot be attributed to maleic acid, furan, furfural, furfuryl alcohol, or 2-furoic acid. However, the difference might be caused by the two substances 5-hydroxymethylfurfural and 2,5-furandimethanol. The present study found no difference in the amount of leached furfuryl alcohol between leachates from furfurylated softwood and furfurylated hardwood species. Earlier studies have indicated differences in grafting of furfuryl alcohol to lignin. However, nothing was found in the present study that could support this. The leachates of furfurylated wood still need to be

“…The species have often been used in bioassays and environmental monitoring of aquatic systems due to the ease and economy of maintaining cultures (Tomasik and Warren 1996;Martínez-Jerónimo et al 2005;Heckmann et al 2007). The initial response of an individual to contaminant exposure is a possible change in its behavior, due to visual or chemoreception (olfaction, taste) damage (Scarfe et al 1983;Riddell et al 2005;Mandrillon and Saglio 2007). Changes in the movement behavior of organisms can therefore be used as a suitable indicator in ecotoxicological risk assessment.…”

Behavior of an organism is affected by exposure to toxic chemicals. However, less has been known about behavioral responses of an organism to stresses of toxic chemicals with different toxic characteristics. In present work, Daphnia magna Straus was exposed to gradient concentrations of deltamethrin, chlorothalonil and nitrofen and the behavioral changes of Daphnia magna under different stress were examined. The results showed that the behavioral responses of Daphnia magna to the tested chemicals were affected in general by exposure concentration, rather than toxic characteristics of the chemicals. The duration of avoidance response (DAR) was in a power regression relationship with the toxic unit (TU), defined as the ratio of exposure concentration of the tested chemical to its LC . DAR was independent of the toxic characteristics of chemicals. However, significant behavior adjustment could be observed after exposure to deltamethrin while only step-by-step decrease in behavior strength could be observed when exposed to chlorothalonil and nitrofen. It was suggested from the observation that avoidance behaviors of Daphnia magna to exposures of chemicals with different toxic characteristics could be similar, while their specific response could be different.
