Mark Hosford
Consultant

Mark supports the IPA in managing scientific research and industry initiatives sponsored by the association to promote the safe production and use of platinum group metals, with a particular focus on advancing the understanding of platinum salt sensitisation and continuing the very substantial progress made in reducing its incidence among PGM refinery and industry workers handling chloroplatinates. Integral to this is the collective expertise of the Health and Environment Science Committee (HESCom) which Mark organises and oversees.
HESCom comprises occupational physicians, toxicologists, industrial hygienists, and PGM chemists from IPA member companies.

Mark has worked in both the public sector and private sector, in industry and consulting, and has been involved with the PGM industry for over a decade.
He is a UK and European Registered Toxicologist and is the current Chair of the UK Register of Toxicologists. He is also a member of the Royal Society of Chemistry’s Toxicology Committee.
