EPA: Restricted Use Products (RUP) Report July 2000

Lindane is used on all kinds of animals, many products containing lindane listed in the right column, are made for specific animals such as cats, dogs, horses, mules, hogs, sheep and cattle.

Cancer Hazard * Lindane may be a CARCINOGEN in humans since it has been shown to cause liver, lung, endocrine glands and other types of cancer in animals.

Animal symptoms that have been observed are increased respiration, restlessness accompanied by frequency of micturition, intermittent muscular spasms of the whole body, salivation, grinding of the teeth and consequent bleeding from the mouth, backward movement with loss of balance and somersaulting, retraction of the head, convulsions, gasping and biting, collapse and death usually within a day.

Lindane Report

LAST WEEK the Pesticides Safety Directorate based in York reviewed the effects of the 'active ingredient' chemical Lindane.

For almost 13 years Angela Brocklehurst, Westie breeder, has expressed concern over the harmful effects of the chemical when it was used as an insecticide in a vapouriser lamp. Her fears were heightened by the mortality and abnormality rates in successive litters of Westie puppies. She also drew parallels when reports of the suspected use of Lindane as a wood preservative caused problems for a midlands' mother. Her investigations and knowledge have led her to provide information to MAFF and the European Commission Co-ordination Review System. Next week Lindane is to be discussed at the Mammalian Toxicology meeting and in May the Fate and Behaviour meeting.

See next week's issue for the breeder's own story, exclusive to OUR DOGS.

 Health Effects of Solvents

Animal studies in the toxicology literature emphasize the role of solvents as neuro-toxins.13 Solvents that act primarily on the central nervous system including toluene, xylene, and styrene have been demonstrated in many animals to cause morphological and biochemical changes in the brain that, in turn, produce neuropsychological, motor, and behavioral effects. Solvents that act as peripheral nervous system toxins have been shown in animals to damage axons, myelin, and the function of axonal transport.
