Fig. 4From: Can a chemical be both readily biodegradable AND very persistent (vP)? Weight-of-evidence determination demonstrates that phenanthrene is not persistent in the environmentPhenanthrene biodegradation half-life versus total hydrocarbon loading (mg/kg) for the soil compartment. Orange triangles indicate data from OECD 307 simulation tests (n = 4). Blue circles indicate data from non-standard experiments (n = 28). Data correspond to experiments with freshly spiked phenanthrene. P/vP thresholds for each compartment are shown with the red dotted lineBack to article page
