Sediment–water distribution of contaminants of emerging concern in a mixed use watershed
Fairbairn, D.J., M.E. Karpuzcu, W.A. Arnold, B.L. Barber, E.F. Kaufenberg, W.C. Koskinen, P.J. Novak, P.J. Rice, and D.L. Swackhamer, Science of the Total Environment, 2015. 505(0): p. 896-904.
This study evaluated the occurrence and distribution of 15 contaminants of emerging concern (CECs) in stream water and sediments in the Zumbro River watershed in Minnesota and compared these with sub-watershed land uses. Sixty pairs of sediment and water samples were collected across all seasons from four stream sites for over two years and analyzed for selected personal care products, pesticides, human and veterinary medications, and phytoestrogens.

Sulfate was a trace constituent of Archean seawater
S. A. Crowe, G. Paris, S. Katsev, C. Jones, S.-T. Kim, A. L. Zerkle, S. Nomosatryo, D. A. Fowle, J. F. Adkins, A. L. Sessions, J. Farquhar, D. E. Canfield.  Science, 2014; 346 (6210): 735 DOI: 
Earth’s ancient oceans held much lower concentrations of sulfate -- a key biological nutrient -- than previously recognized, according to new research. The findings paint a new portrait of our planet's early biosphere and primitive marine life. Organisms require sulfur as a nutrient, and it plays a central role in regulating atmospheric chemistry and global climate. Article>>
