Adsorbable Organic Halogens is a measurement
often used in waste water testing to indicate the overall level of
the halogens, fluorine, chlorine, bromine and iodine. This "sum
parameter" comes from a standard analytical procedure, which gives
no information on the source or nature of halogens present nor on
their toxicity. It has the advantage of being simple to measure;
alternative methods of measuring levels of individual compounds are
complex and require costly equipment.
