Algology () The study or science of algae or seaweeds.

For both the marine and freshwater risk assessments, acute LC50 values were converted to chronic values using an acute to chronic ratio (ACR) of 2 (normally an ACR of 10 is used; however, because manganese is an essential element, a factor of 2 was used following ANZECC/ARMCANZ [2000] guidelines). Both these extrapolated acute values and chronic EC50s were then converted to chronic NOECs by applying a factor of 5, according to ANZECC/ARMCANZ (2000) guidelines. In other words, each acute LC50 was divided by 10 (i.e., 2 × 5) and each algal EC50 value (regarded as chronic) was divided by 5 prior to the species sensitivity distribution being undertaken. It would be better to use experimentally derived acute to chronic conversion factors, but these were not available for manganese.
