ATOS Antimony Trioxide Stakeholders is comprised of Manufacturers and Downstream Users of Antimony Trioxide.
In 2004, a group of antimony trioxide producers and users successfully joined forces to form the Antimony TriOxide Stakeholders (ATOS).
Their mission was to develop scientific information needed to support (di)antimony trioxide (ATO) through the EU Risk Assessment process.
ATOS dissolved beginning of 2008. ATOS responsibilities have been taken over by i2a.
