Table 1—Acute Water Quality Criteria for Protection of Aquatic Life in Ambient Water

EPA recommends that metals criteria be expressed as dissolved concentrations (see appendix A, I.A.4 for more information regarding metals criteria).

Parathion	^d 0.065	n/a
^a CMC = CMC^tr.
^b CMC^d = (CMC^tr) CF. The CMC^d shall be rounded to two significant digits.
^c CMC should be considered free cyanide as CN.
^d CMC = CMC^t.
Notes:
The term “n/a” means not applicable.
CMC is Criterion Maximum Concentration.
CMC^tr is the CMC expressed as total recoverable.
CMC^d is the CMC expressed as a dissolved concentration.
CMC^t is the CMC expressed as a total concentration.

^a CMC^tr = exp {m_A [ln (hardness)] + b_A}.
^b CMC^d = (CMC^tr) CF. The CMC^d shall be rounded to two significant digits.
^c CMC^t = exp m_A {[pH] + b_A}. The CMC^t shall be rounded to two significant digits.
Notes:
The term “exp” represents the base e exponential function.
The term “n/a” means not applicable.
CMC is Criterion Maximum Concentration.
