Autocorrelation descriptors encoding lipophilicity, molar refractivity, the H-bonding acceptor ability and H-bonding donor ability of the molecules were used to describe glycols, glycol ethers, and xylenes characterized by their adult and developmental toxicities to Hydra attenuata. A PLS regression analysis was employed to derive a QSAR model allowing to simulate both endpoints. Comparisons were made with classical regression analyses using the 1-octanol/water partition coefficient as molecular descriptor.
