EC10 = Effect concentration for 10% of test population ns = Not specified
EC25 = Effect concentration for 25% of test population OM = Organic matter content
EC50 = Effect concentration for 50% of test population PHY = Physiology
ERE = Ecologically relevant endpoint REP = Reproduction
GRO = Growth Y = yes
LOAEC = Lowest observed adverse effect concentration cnbd = Could Not Be Determined
MATC = Maximum acceptable toxicant concentration. Geometric mean of NOAEC and LOAEC. Bioavailability Score described in Guidance for Developing Eco-SSLs (U.S. EPA, 2003)
N = No
