TABLE 4
BRIEF COMPARISON OF CONVENTIONAL AND TOXIC POLLUTANTS


'Conventional

One to two dozen pollutants fall
into this' category

Often large quantities required to
produce impact (e.g. thousands
lbs/day)

Concentrations often expressed as
ppm (mg/l)

Often travel in dissolved form


Mean residence time within water
bodies often equal to or less than
the moan residence time of moving
waters


Many biodegrade
substances


into harmless


ToxiC

Thousands fall into this category;
many more being synthesized

Small quantities can produce impact
(e.g. few lbs/days)


Concentrations often expressed as
ppb (yg/l), or in smaller units

May be highly sorbed to suspended
and bedded sediments


Can reside in bedded sediments for
years



Many are transformed to chemicals
which are also toxic; others are
resistant to degradation and
bioconcentrate
