EPA Unveils Final Analysis Of RDX, First IRIS Assessment of Trump Era

摘要

After months of delays, EPA has published its final Integrated Risk Information System (IRIS) assessment of Royal Demolition Explosive (RDX), a munitions chemical present at many military sites, the first such analysis released since the Trump administration took office and launched a review of the agency's premiere hazard assessment program. EPA announced Aug. 30 that it has finalized the IRIS assessment of the human health risks of exposure to hcxahydro-1,3,5-trinitro-1,3,5-triazine, also known as RDX, updating IRIS' original assessment of the chemical published in 1993. The final report concludes a process that took more than five years. The assessment is available on InsideEPA.com. (Doc. ID: 214809) The final assessment adopted risk values slightly less stringent than what the agency had last adopted in 1993. The values generally track with the current values as well as those EPA proposed, though the agency did not appear to respond to advice from its science advisers to strengthen its non-cancer values to account for additional neurotoxic effects that the draft had not addressed. As such, the agency rejected early concerns from the Department of Defense (DOD) which had sought to weaken the toxicity levels.
