Health Based Environmental Screening Levels (HBESLs). These HBESLs are endorsed by military policy as criteria to assess potentially contaminated soils (Table 6.6) (USACHPPM, 1999 OASA, 1999 Watson and Dohslager, 2007).

Other than for MPA (see discussion under VX), no guidelines for environmental cleanup of degradation products are available. The estimated oral RfD for GD is 0.004 qg/kg/day (Opresko et al., 1998,2001). Health-based environmental screening levels forGD for residential... 

Various standards and guidelines have been developed for sulfur mustard. These values are applicable to occupational exposures, emergency planning and response efforts, and remediation efforts. Airborne exposure limits (AELs) and health-based environmental screening levels (FlBESLs) for sulfur mustard have been developed by the U.S. Army (USACFIPPM, 1999, 2000). Most health-based criteria for sulfur mustard vapor exposure are based upon protection of the eyes and respiratory tract, which are the most sensitive targets.
