Clustering chlorine reactivity of haloacetic acid precursors in inland lakes
Zeng T. and W. A. Arnold. 2014.
Environmental Science & Technology
Inland waters only cover about 1% of the Earth’s surface but play an integral role in regulating the carbon cycle and climate on a global scale.1−4 Rising levels of dissolved organic matter (DOM) in inland lakes and streams have been observed in North America and Europe. Article>>

Phytoestrogens in the environment: I. Occurrence and exposure effects on fathead minnows. Environmental Toxicology and Chemistry
Rearick, D.C., N. T. Fleischacker, M. M. Kelly, W. A. Arnold, P. J. Novak and H. L. Schoenfuss. 2014.
Naturally occurring phytoestrogens may mimic biogenic estrogens and modulate endocrine action in vertebrates. Little is known, however, about their temporal and spatial variability in the environment and the biological effects associated with exposures. The present study assessed the environmental presence of phytoestrogens in human-impacted and relatively pristine areas. Article>>

Wet deposition of mercury decreased considerably in northern Minnesota from 1998-2012. Wet deposition of sulfate and hydrogen ion—also important in the aquatic mercury cycle—also decreased during the same period. Consistent with decreases in these atmospheric pollutants, two of four study lakes in Voyageurs National Park also showed considerable decreases in methylmercury in water and year-old perch. However, in a third lake, methylmercury levels increased in water and fish; a fourth lake showed no consistent trend.
