Parameters: To use Bio-Aquatic LC50 testing. Correctly interpreted, it stands for the given amount of time (usually 24 or 48 hours) that the test organisms are exposed to a controlled water environment contaminated with the test product solution (oil/wire rope lubricant) at specific intervals.
It is then verified as the test progresses how many parts per million (PPM) added to the bio-aquatic test environment it takes to kill 50% of the test organisms used.
The higher the PPM rating, the less environmental friendly (safe) it is to a marine environment.
Product: Dynagard Blue (wire rope lubrication of the KIRKPATRICK System)
Test: Undertake a 48 hour Bi-Aquatic Test, using the highly sensitive Microscopic Estuary Shrimp Species Mysidopsis Bahia for 48 hours.
Result: 56,109 PPM
The outcome of this test means that it requires an extremely high amount of the product to be in the water to do harm to the sensitive test species. The reality is, that the amount required to do harm would never normally occur in the real world and via normal use of the the product.
Other similar use products are typically 5,000 PPM in the same test and the Kirkpatrick System made it to over 55,000 PPM.
