The Ames Test offered a fast and inexpensive way to identify carcinogens, leading to the banning of chemicals linked to cancer and birth defects.<\/p>\n

Bruce Nathan Ames, a biochemist who discovered a revolutionary method of detecting potential carcinogens, paving the way for the banning of many commonly used chemicals, died on Oct. 5 in Berkeley, Calif. He was 95.<\/p>\n

His wife, Giovanna Ferro-Luzzi Ames, said his death, in a hospital, was from complications after a fall.<\/p>\n

The so-called Ames Test, developed in the 1970s, is still used by drug manufacturers and pesticide companies to check the safety of their products. It involves exposing chemicals to a mutant strain of salmonella bacteria that Dr. Ames created; how the bacteria responds to a chemical makes it possible to determine whether that chemical caused DNA damage and therefore might lead to cancer in humans.<\/p>\n

In an America increasingly concerned about the effects of pollution and industrial chemicals, the test offered a quick, inexpensive alternative to animal testing, which was so prohibitively expensive that regulators were able to test only a fraction of chemicals on the market.<\/p>\n<\/div>\n<\/div>\n

\u201cIt changed the regulatory sphere,\u201d said Angela Creager, a science historian at Princeton University who is writing a book about the Ames Test. \u201cIt showed that it was actually possible to get toxicity information on every chemical if we wanted to.\u201d<\/em><\/p>\n

After capturing the attention of the national press, Dr. Ames remained in the spotlight as he used the Ames Test to expose the toxicity of a number of commonplace chemicals.<\/p>\n
