The scientist who first linked smoking to lung cancer was [later] paid by a chemicals firm while investigating cancer risks in the industry. Professor Sir Richard Doll held a consultancy post with US firm Monsanto for more than 20 years. *The BBC has seen private letters which show that Sir Richard ... received a US$1,500-a-day consultancy fee from Monsanto in the mid-1980s.* During that time he investigated the potential cancer causing properties of the powerful herbicide Agent Orange, made by the company. Sir Richard [argued] that there was no evidence that Agent Orange caused cancer. Professor Lennart Hardell, of the Oncology Department at University Hospital Orebro, Sweden, has also studied the potential hazards posed by Agent Orange. He was one of the scientists whose work was dismissed by Sir Richard. He said: It's quite OK to have contacts with industry, but you should be fair and say 'well, I'm [working] as a consultant for Monsanto." Further documents obtained by The Guardian newspaper allegedly show that Sir Richard was also paid a 15,000 fee by the Chemical Manufacturers Association, and chemicals companies Dow Chemicals and ICI for a review of vinyl chloride, used in plastics, which largely cleared the chemical of any link with cancers apart from liver cancer. Sir Richard's views on the chemical were used by the manufacturers' trade association to defend it for more than a decade.
