A study was performed to assess the acute
toxicity of Lakeland ACP 70 to rainbow trout (Oncorhynchus mykiss) under
semi-static conditions. The study was conducted in accordance with the
EEC Methods for Determination of Ecotoxicity Annex to Directive
92/69/EEC (OJ. No. L383A, 29.12.92) Part C, Method 1 "Acute toxicity for
Fish" and the OECD Guideline for Testing of Chemicals No. 203 "Fish,
Acute Toxicity Test". Groups of seven juvenile fish were exposed to a
range of concentrations of Lakeland ACP 70 dispersed in water.
Observations were made on the numbers of dead fish and the incidence of
sublethal effects after 3, 6, 24, 48, 72 and 96 hours exposure. Results
were reported as LC50 (96 h) 3.2 mg/L.
A sample of ACP 70 was assessed for its
potential toxicity to juvenile turbot in a semi-static test over 96
hours in accordance with the PARCOM method 1995, OECD guideline 203.
Nominal test concentrations of ACP 70 were prepared over the range of
1.0 mg 1-1 to 10.0 mg 1-1. Juvenile turbot were exposed to the test
concentrations in order to determine the concentration which killed 50%
of the test organisms over 96 hours (LC50). Results were reported as
LC50 (96 h) 3.6 mg/L.
Results are available for one species of
freshwater fish and one species of marine fish.
