The first stage of environmental checks around Grenfell Tower show that there is no increased risk to health from the aftermath of the fire.
The levels of chemicals found in the Grenfell area are consistent with those generally found in London.
The checks were carried out by independent specialists and have been verified by experts on the independent Science Advisory Group.
The process for carrying out the checks was agreed by all members of the Science Advisory Group.
Professor Anna Stec, who originally suggested testing around the site, is a former member of the Group who provided advice to the group on fire toxicity.
Sir Patrick Vallance, Government Chief Scientific Adviser and Chairman of the Science Advisory Group said:
Following a review of the technical documents by the Science Advisory Group, they have agreed that the approach taken was scientifically rigorous and met the agreed specification.
The Group has confidence in the results from Stage 1, which will inform the Stage 2 investigation.
To provide further reassurance to the community, a second stage of testing will also be carried out. The Stage 1 results do not show levels requiring any change to the investigation strategy.
Anyone in the Grenfell community who remains concerned about their health should contact their GP, who is best placed to assess individual needs and consider the most appropriate treatment.
