Re: medical waste incinerator stack testing

  Hi, Rob,
        Yes, there is a very good reason to
  be suspicious of re-tests for medical
  waste incinerators for metals. Specifically,
  mercury thermometers and other mercury-laden
  devices and batteries can appear (or not appear)
  in the waste stream at any time. If there is no
  "scrubbing" equipment and no carbon or lime
  injection into the stack (which can divert the
  mercury into the ash instead of into the air)
  then stack measurements of mercury would
  sometimes be very high, other times relatively
