EK 35®
ENVIRONMENTAL DATA
Acute and Chronic Aquatic Toxicity
PERFORMED BY: ABC Laboratories, Inc.
REPORT DATA: September 16, 2002
SUMMARY: As part of the US EPA Environmental Technology Verification (ETV) Program EK 35® (Liquid Sample A) was tested to determine chronic and acute toxicity to aquatic species: Ceriodaphnia dubia, Fathead minnow and Americamysis bahia (Mysid shrimp).
Concentrated EK 35® was evaluated per the following EPA test methods:
*Methods for Measuring the Acute Toxicity of Effluents and Receiving Water to Freshwater and Marine Organisms, EPA/600/4-90/027F.
*Short-term Methods for Estimating the Chronic Toxicity of Effluents and Receiving Waters to Freshwater Organisms, EPA/600/4-91/002.
*Short-Term Methods for Estimating the Chronic Toxicity of Effluents and Receiving Water to Marine and Estuarine Organisms, EPA/600/4-91/003.
RESULTS: The results indicate that EK 35® has low aquatic toxicity levels and is not considered an aquatic pollutant.
Ceriodaphnia dubia Acute, EC50: >1000mg/L
Fathead minnow Acute, LC50: 271mg/L
Americamysis bahia Acute, EC50: 111mg/L
Ceriodaphnia dubia Chronic, EC50: >1000mg/L
Fathead minnow Chronic, LC50: 97.3mg/L
Americamysis bahia Chronic, EC50: 58.6mg/L
