Copper Naphthenate: Beyond the myth!

Sodium fluoride/copper naphthenate toxicosis in cattle.

Fourteen cattle on a Kansas pasture died from ingestion of a wood preservative compound containing sodium fluoride and copper naphthenate. Clinical signs included depression, anorexia, ataxia, diarrhea, and recumbency. Grossly visible lesions included perirenal edema, pale kidneys, and forestomach ulceration. All 3 cows that had postmortem evaluations had extensive renal cortical tubular necros...

In-service wood preservative test on the Howe truss railway bridge, Waikino

Some of the major components of a Howe truss bridge, built from durable Australian hardwoods, were treated with preservatives applied to the surface and inserted into holes bored into the components. The preservatives included two copper naphthenate formulations, two formulations based on 2(thiocyanomethylthio) benzothiazeole (TCMTB), two boron-based products and an oxine-copper formulation. Th...

Structure-Affected Bioactivity of Triorganotin Compounds

The biocidal activity of 8 triorganotins R3S11X (R = butyl, phenyl, benzyl; X = oxide, chloride, acetate, naphthenate, TV, JV-diethyldithiocarbamate) on brown rot fungi, moulds mixture, benthic organisms, plankton alga Scenedesmus quadricauda, and crop plant has been investigated. The results suggest dependence between lipophilicity of bounded R groups and intensity of unfavourable effect. The ...

Copper tolerance of brown-rot fungi: Oxalic acid production in southern pine treated with arsenic-free preservatives

The voluntary withdrawal of chromated copper arsenate (CCA)-treated wood from most residential applications has increased the use of non-arsenical copper-based organic wood preservatives. Because the arsenic component of CCA controlled coppertolerant fungi, scientists have renewed interest in and concern about the decay capacity in the important copper-tolerant group of brown-rot fungi. We have...
