The UK is to increase testing for so-called "forever chemicals" in the environment as part of a national plan to tackle the substances, which have prompted environmental and health concerns.
The group of chemicals, also known as PFAS, are used in many everyday products because of their oil resistant and waterproof properties.
But scientists are concerned because their chemical structures mean they accumulate and remain in the environment, with a small number of PFAS known to be toxic.
The government says that by 2029 it wants to align more closely with regulations issued by the EU, which is looking to prohibit all non-essential uses.
Some environmental groups and the water industry have urged the government to act more quickly in banning the chemicals.
