Cancer-causing chemicals. Bottles of chemicals that can cause cancer (carcinogens),with diagrams of the molecular structure of toluene and nitrated toluenes. Many of these chemicals have nitro (NO2) groups in their molecules,which is thought to be a reason for their carcinogenicity. Photographed in the Health and Pollutants Laboratory of the INRS (the French National Institute of Research and Safety),Nancy,France. Tests are carried out here to establish the toxicity and cancer-causing properties of different materials,chemicals and pollutants | |
