Copper arsenite-acetate

Copper compounds are used routinely and widely to control freshwater snails that serve as intermediate vectors of schistosomiasis and other diseases that afflict humans (Hasler 1949 NAS 1977 Rowe and Prince 1983 Winger etal. 1984 Al-Sabri etal. 1993). These compounds include copper sulfate, copper pentachlorophenate, copper carbonate, copper-tartaric acid, Paris green (copper arsenite-acetate), copper oxide, copper chloride, copper acetyl acetonate, copper dimethyl dithiocar-bamate, copper ricinoleate, and copper rosinate (Cheng 1979). Also, many species of oyster enemies are controlled by copper sulfate dips. All tested species of marine gastropods, tunicates, echinoderms, and crabs that had been dipped for 5 seconds in a saturated solution of copper sulfate died if held in air for as little as a few seconds to 8 h mussels, however, were resistant (MacKenzie 1961). 

Toxic are all soluble compounds of arsenic like the As(UI) and As(V) halides, arsenic pentoxide, salts of die arsenious (lU-arsenite) and arsenic (V-arsenate) acid, e.g., copper arsenite [Cu(AsQ2)2], copper arsenite acetate [3Cu(As02)2-Cu(CH3C00)2l, and lead arsenate (Pb3(As04)2l [4,5].

Like zinc, copper and its compounds have been used since ancient times, with copper dust, acetate, sulfate and carbonate reported in Egyptian and Hindu prescriptions, and also used by Hippocrates and Galen. Copper arsenite was used in 1892 for anemia and debility. Copper sulfate was recommended to strengthen man, to stimulate the heart and blood vessels, to increase deposition of fat and to treat anemia. The adult requirement is 1.25 mg Cud-1, about one third of which is absorbed. TPN should be supplemented with 0.5—1.5 mg d-1 (adults) and 20 gg (kg weight)-1 d-1 (children). 

Inorganic arsenicals find limited use as pesticides. Examples include arsenious oxide in cattle dips, zinc arsenite as a wood preservative, and calcium and lead arsenates and Paris green (double salt of copper arsenite and copper acetate) as insecticides30. ... 

Alkaline earth metal arsenites are less soluble than those of the alkali metals and heavy metal arsenites tend to be insoluble. Orthoarsenites are known, for example, AgsAsOs. Once utiUzed as a green pigment was the copper arsenite CuHAsOs, and as an insecticide, Paris green, 3Cu(As02)2 Cu(C2H302)2, which is an acetate arsenite. None of these is in nse at the present time.

The identification with copper acetate arsenite stabihses late in the nineteenth century and is to be considered the primary meaning. For a discussion of the chemistry, see the entry for the copper arsenite group. The related Scheele s green is discussed imder that term. 

Seemingly a copper-arsenic green (q.v.). Terry (1893) describes the process as involving the preparation of copper arsenite from copper sulfate and sodium arsenite ( arsenite of soda ). The precipitate is then treated widi acetic acid or, interestingly, formic acid the former would result in the usual copper acetate arsenite, the latter in copper formate arsenite. Terry comments The pigment thus produced is of good colour, but its superiority would not seem to justify the use of such an expensive article as pure formic acid, nor the minute adjustment of the proportions of die ingredients, in an operation to be conducted on a commercial scale. ...
