Title: Acute toxicity of furazolidone on Artemia salina, Daphnia magna, and Culex pipiens molestus larvae

Abstract

As a result of evidence of the ecotoxicity of nitrofurans, the acute toxicity of furazolidone was tested in vivo on two aquatic organisms, Artemia salina and Daphnia magna, which are both crustaceans. Toxicity studies were also performed on larvae of Culex pipiens molestus. Results indicated a significant toxicity of the compound on Culex pipiens and Daphnia magna, while Artemia salina proved to be the least sensitive.

  • To know the effects on emergence, longevity, fertility, and mating competitiveness, 2-day-old male pupae of Culex pipiens molestus were irradiated with various dosages of /sup 60/Co gamma rays ranging from 1,000 to 12,000 R. Few effects of the gamma irradiation on both emergence and longevity were noticed. However, high levels of egg-mortality could be produced in males by exposing pupae to irradiation. Exposure to 10,000 R produced 99.1% egg-mortality and a dose of 12,000 R gave a 99.9% eggmortality. The competitiveness test showed that mating activity of radiosterile males was lower than that of the normal males. (auth)
  • Radioactive larvae, pupae, and adults were produced by adding Na/sub 2/ HP/sup 32/O/sub 4/ to the larval rearing medium, consisting of tap water and dog food pellets. For all initial concentrations of P/sup 32/ in the larval medium, the larger the larva, the greater the uptake of P/sup 32/. At an initial concentration of 10.0 C of P/sup 32/ per ml, about half of the larvae died within 10 days. P/sup 32/ had little noticeable effect on larval growth up to a concentration of 3.0 C/ml; above this concentration, growth was greatly retarded. Pupation by larvae in media having amore » P/sup 32/ concentration 1.0 C/ ml was prolonged to over 5 weeks, and at concentrations of 3.0 and 5.0 C/ml, only a small percentage of the larvae initially introduced into the media pupated. At P/sup 32/ concentrations of 5.0 C/ml or higher, no adults emerged. However, at 1.0 C/ml, the next lower concentration tested, 50% of the treated individuals emerged. It is suggested that, for efficient utilization of P/sup 32/ in large-scale field experiments, a concentration of 1.0 C/ml would be needed to produce adult mosquitos sufficiently radioactive to be readily detectable by a scaler or survey meter. It was concluded that radiation may affect growth and development of mosquitoes by disruption of enzyme systems and inhibition of various processes necessary for pupal differentiation. (TCO)« less
  • Ethanol is a commonly used solvent in toxicity testing, yet there are few studies in the literature devoted to its toxicity to zooplankton. The purpose of this study was to compare the response of Daphnia magna Straus 1820 and Ceriodaphnia dubia J. Richard 1894 to ethanol. Two temperatures were selected because most toxicity data involving D. magna has been carried out at 20/sup 0/C while all discussions concerning C. dubia appear to relate to temperatures oscillating around 25/sup 0/C. Thus, the response of these two organisms to ethanol was examined at 20/sup 0/C and at 24/sup 0/C.r
