The IPTC is one of the longest standing scientific meetings in its field. It started in the UK in 1979 and has since been held 11 times, rotating between continents. The 2022 conference will bring the conference to the heart of the beautiful American Southwest in picturesque Santa Fe, New Mexico, USA. This conference is a meeting place of thought leaders, research directors and emerging stars in the many different fields of particle and fiber toxicology. It is a place where new ideas are discussed and cultivated, and where new initiatives are conceived and launched.
