Примери за carcinogen

• Large concentrations of polyaromatic compounds, many of which are known carcinogens, have spilled into the soils at the historic fuel depot areas.

• Included in this group are chloroform and related substances such as chlorinated acetates, many of which are listed as suspected human carcinogens.

• The passage of time is a ubiquitous carcinogen to which we are all exposed but age itself is not the mechanism of carcinogenesis.

• Our dietary intake of natural pesticides and carcinogens is far greater than our intake of synthetic pesticides.

• There are sufficient experimental animal studies to implicate ethanol as a human carcinogen.

• The present study is the first report of tenascin expression in bile duct cancer induced by a combined parasitic infection and carcinogen treatment.

• Cumulative genetic defects in carcinogen metabolism may increase breast cancer risk.

• There are in general three main groups of carcinogens (producing or initiating cancer): chemicals, radiation, and microbes.

• This agent is a well-known carcinogen with conflicting indications of its mutagenic activity.

• Natural carcinogens and toxins are never produced by accident in plants or microbes.

• For example, we may quite legitimately place controls on exposure to low level carcinogens, even if their effect on human health has not been proven.

• An animal model was sought that would maintain test sensitivity for identifying carcinogens but would be less resource intensive.

• On the other hand, carcinogens which act directly on genetic material would be viewed with much more suspicion.

• The products of genetic engineering are organic creatures, not chemical pollutants or carcinogens (unless they are specifically designed to produce such substances).

• We may demand that every nation adopt a polluter-pay principle; but the pollution tax, for the same carcinogen in the same industry, will generally be different.
