Fingerprint-based detection of acute aquatic toxicity

In this work we show the effectiveness of 2D structural fingerprints in the prediction of aquatic toxicity of chemical compounds, creating a self-contained system for structure-based aquatic toxicity classification. Using the data from the U.S. Environmental Protection Agency Fat Head Minnow (EPA-FHM) dataset [1] we build a nonlinear RBF SVM [2] classifier that distinguishes acutely toxic compo...

Acute toxicity of 4-nonylphenol to aquatic invertebrates in Taiwan.

Acute toxicity of 4-nonylphenol (NP) was examined in six freshwater species from three phyla - platyhelminthes, arthropoda and mollusca. Values of the 48-hour LC(50) of NP for six species ranged from 20 to 508 ug/L and values of the 96-hour LC(50) for four species ranged from 120 to 457 ug/L. The most sensitive species tested was a water flea, Ceriodaphnia cornuta, with a 48-hour LC(50) of 20 m...

Acute toxicity of birch tar oil on aquatic organisms

Birch tar oil (BTO) is a by-product of processing birch wood in a pyrolysis system. Accumulating evidence suggests the suitability of BTO as a biocide or repellent in terrestrial environments for the control of weeds, insects, molluscs and rodents. Once applied as biocide, BTO may end up, either through run-off or leaching, in aquatic systems and may have adverse effects on non-target organisms...

Aquatic acute toxicity assessments of molybdenum (+VI) to Daphnia magna.

Generally, molybdenum (Mo) metals in the environment are very rare, but wastewater discharges from industrial processes may contain high concentrations of Mo, which has the potential to contaminate water or soil if not handled properly. In this study, the impact of three common compounds of hexavalent Mo (sodium molybdate (Na2MoO4‧2H2O), ammonium molybdate ((NH4)6Mo7O24‧4H2O) and molybdenum tri...

Acute cadmium toxicity studies upon nine species of aquatic insects.

Continuous-flow bioassays were employed to determine 96.hour median tolerance limits (TLm), for the stonefly. Pteronnrcrllu hadia (Hagen) (TLm was 18.0 mg Cd/l) and the mayfly, Ephemerella grundis grarzdis Eaton (TLm was 28.0 mg Cd/l). Ninety-six hours TLm values for other species of aquatic insects tested were not determined, since these species were relatively insensitive to cadmium. Insects ...
