6-Des-2001 (11)<br />
Type of test: static<br />
Species:<br />
Physa heterostropha (fresh water snail)<br />
Exposure period: 96 hours<br />
Unit: mg/l Analytical monitoring: yes<br />
LC50 = 9<strong>40</strong><br />
Method:<br />
other<br />
Year: 1968 GLP: no data<br />
Test substance: as prescribed by 1.1-1.4, purity: A.C.S.-grade<br />
chemicals<br />
Remarks:<br />
Snails were exposed to a graded series of KCl and<br />
synthetic dilution water and controls. Eighteen<br />
series of bioassays were done. Tests were made in 1<br />
litre of solution at 20 degrees C. Dissolved oxygen<br />
concentrations were maintained between 5 and 9 ppm.<br />
No food was given during the test period or during<br />
the 36 hours before the tests began. Snails were<br />
acclimatized to the dilution water and other test<br />
conditions for 2 weeks before being used as<br />
experimental organisms. The nominal concentrations<br />
of KCl were not measured.<br />

Type of test: static<br />
Species:<br />
Dreissena polymorpha (zebra mussel)<br />
Exposure period: 48 hours<br />
Unit: mg/l Analytical monitoring: yes<br />
LC50:<br />
= 150 (20-25 mm ad.)<br />
LC50:<br />

Method:<br />

Year: 1993 GLP: no data<br />
Test substance: as prescribed by 1.1-1.4; 99 % active ingredient<br />
Remarks:<br />
Mussels (20-25 mm and 5-8 mm) were obtained from<br />
Lake Eire, Ohio, and maintained in 2000 l aquaria<br />
containing dechlorinated municipal water. Before<br />
exposures, two size classes of adult mussels from<br />
the stock culture were placed in glass petri<br />
dishes and allowed to attach. The mussels were<br />
exposed in 3.8 l glass jars containing 2.5 l test<br />
water without aeration. Test water was<br />
reconstituted soft water of pH 7.7, alkalinity<br />
6x10 -4 m/L (30 mg/l as CaCO 3 ), and total hardness<br />
<strong>40</strong> mg/l as CaCO 3 . Tests were conducted at 17<br />
degrees C. Dissolved oxygen, pH and temperature<br />
were measured daily. Treatment of 10 animals per<br />
vessel were triplicated.<br />
