<br />Acute = one day max.,, Chronic = 30 day average. These values mere taken
<br />from Table IV, CDOH Reg. 31, using a mean hardness of 400 mq/1. All
<br />acute/chronic values are the 'dissolved' form.
<br />A = Standard is 0.02 mg/1 (un-ionized). Detection limit is 0.10 mg/1.
<br />B = Standard is 0.01 ug/1. Detection limit is 0.2 ug/1.
<br />C = Standard is 0.002 mg/1 (un-ionized). Detection limit is 0.02 mg/1.
