After being used for more than 70 years, the International Agency for Research on Cancer (IARC) has classified one of the world’s most widely used weed killers as “possibly carcinogenic”.
Cancer researches at the World Health Organisation (WHO)said that the results of the studies were not conclusive.
The weedkiller is called 2,4-dichlorophenoxyacetic acid but is more commonly known as 2,4-D. IT is used widely in the management of agricultural crops, forestry, grass and bodies of water to prevent the growth of weeds. 2,4-D has been in use since the 1940s and is an active ingredient in more than 1,500 products.
2,4-D was used in the production of Agent Orange, a chemical weapon used by the US military in the Vietnam War.
