Vinegar test Vinegar test Vinegar test is a cervical cancer testing method that uses acetic acid, a major component of vinegar. It has been found to be useful as an effective and inexpensive screening test. It has the potential, say researchers from the University of Zimbabwe and Johns Hopkins University, to improve the chances of preventing cancer in developing world. The technique, termed VIA (Visual Inspection with Acetic Acid)/Cryo, was endorsed by the World Health Organization in 2010. Vinegar is brushed on a woman’s cervix and precancerous spots turn white. These can be instantly frozen off with a metallic probe cooled with
2,4-Dichlorophenoxyacetic acid reduces drift; the choline salt form of 2,4-D is less volatile than 2,4-D. 2,4-Dichlorophenoxyacetic acid 2,4-Dichlorophenoxyacetic acid (usually called 2,4-D) is an organic compound with the chemical formula CHClO. It is a systemic herbicide which selectively kills most broadleaf weeds by causing uncontrolled growth in them, but leaves most grasses such as cereals, lawn turf, and grassland relatively unaffected. 2,4-D is one of the oldest and most widely available herbicides and defoliants in the world, having been commercially available since 1945, and is now produced by many chemical companies since the patent on it has long since expired. It can
