Examining the PM6 semiempirical method for pKa prediction across a wide range of oxyacids
The pKa estimation ability of the semiempirical PM6 method was evaluated across a broad range of oxyacids and compared to results obtained using the SPARC software program. Compound classes under…

Contaminant Trapping Behind Large Dams: A Mini-Review
It appears likely that the installation of many large dams on major rivers worldwide over the past century has led to large and complex contaminant loadings becoming trapped in the sediments behind…

Extending the semi-empirical PM6 method for carbon oxyacid pKa prediction to sulfonic acids: Application towards congener-specific estimates for the environmentally and toxicologically relevant C1 through C8 perfluoroalkyl derivatives
A positive bias in the semi-empirical PM6 method for estimating pKa values of sulfonic acids was corrected by a correlation developed between non-adjusted PM6 pKa values and the corresponding exper…

The Antarctic ‘ozone hole’ combined with no sea ice causes severe oxidative damage in echinoid embryos
Over the past three decades, the ‘ozone hole’ has caused a transient increase in the levels of ultraviolet B radiation (UV-B, 280 to 320 nm) reaching Antarctic coastal marine ecosystems1. The dir…
