“…Whereas in the 1996 experiment the mean residue was 57 µg kg -1 total endosulfan, in the present experiment the mean was 220 µg kg -1 total endosulfan. These values are within the range found in the same species in cotton-growing areas in New South Wales (Nowak & Julli 1991). The liver residues consisted of 34.1% alpha, 23.2% beta and 42.7% sulphate in the 1996 experiment, whereas in the present experiment the residues in the liver consisted only of the alpha isomer.…”

“…Furthermore, while endosulfan is not as persistent as other organochlorines, it can accumulate in fish organs, and the residues can affect the fish for long periods after exposure. During the field sampling, endosulfan was detected in all catfish from cotton-growing areas, including fish sampled months after endosulfan had been used (Nowak & Julli 1991). It can therefore be assumed that the organ structure of wild fish populations is affected.…”

“…Samples were analysed individually from each fish. Endosulfan residues in the fish liver were analysed as described previously (Nowak & Julli 1991). Briefly, tissue was emulsified with trisodium citrate and disodium hydrogen orthophosphate and mixed with sodium sulphate.…”

“…Endosulfan residues were detected in wild fish from the areas where endosulfan is used (Pick et al 1981, Matthiessen et al 1982, Nowak 1990, Nowak and Julli 1991. The residues usually consisted of the alpha isomer and endosulfan sulphate, which indicates lower persistence of the beta than the alpha isomer in fish (Nowak and Julli 1991).…”

“…The residues usually consisted of the alpha isomer and endosulfan sulphate, which indicates lower persistence of the beta than the alpha isomer in fish (Nowak and Julli 1991). Catfish, Tandanus tandanus, experimentally exposed to endosulfan under laboratory conditions contained the highest residue levels in liver, gills, kidney and brain (Nowak 1992).…”

: Endosulfan is an organochlorine insecticide, consisting of a mixture of two isomers: alpha and beta endosulfan. Endosulfan residues were determined in livers and gills of carp exposed to lethal and sublethal concentrations of endosulfan. The fish which were exposed to a lethal concentration contained the highest residue level in both liver and gills. In carp liver, the percentage of beta endosulfan in the residue decreased with time between exposure and collection of samples whereas the percentage of endosulfan sulphate increased. Carp killed by exposure to endosulfan had a significantly greater ratio of beta to alpha endosulfan and a significantly greater percentage of beta endosulfan in their livers. There was no such clear relationship for the residue composition in fish gills. The determination of residue composition, in particular the percentage of beta endosulfan or the ratio of beta to alpha isomers is recommended in investigations of fish kills when endosulfan is a suspected cause.

Semistatic bioassays of endosulfan with native and introduced Australian fish indicated that they are sensitive to this insecticide at low concentrations. The introduced European carp (Cyprinus carpio) was the most sensitive species, with a measured 96‐h LC50 of 0.1 μg/L, whereas the native eastern rainbow fish (Melanotaenia duboulayi) and silver perch (Bidyanus bidyanus) were the least sensitive, with measured 96‐h LC50 values of 2.4μg/L. The measured 96‐h LC50 values of endosulfan for bony bream (Nematolosa erebi), golden perch (Macquaria ambigua), and rainbow trout (Oncorhynchus mykiss) were 0.2, 0.5, and 1.6 μ/L, respectively. Toxicities of endosulfan in Sydney mains water and Mehi River water were similar when rainbow fish, golden perch, and silver perch were used as test animals. The initial measured concentration was about 42% of the nominal concentration, whereas final measured concentration after 24 h in semistatic tests declined to 5.6% of the nominal concentration. The toxicity of endosulfan was similar in Australian native and introduced fish and in overseas fish, but varied markedly with test method. The 96‐h LC50 values for one species, the rainbow fish, varied from 0.5μg/L when reported as measured concentrations in a flow‐through test to 11.4 μg/L as nominal values in a static test. These differences span much of the variation found in 96‐h LC50 values for all fish species described in the world literature.
