Microplastics in sediments: A review of techniques, occurrence and effects 5
Van Cauwenberghe, Lisbeth; Devriese, Lisa; Galgani, Francois; Robbens, Johan; Janssen, Colin R..
Microplastics are omnipresent in the marine environment and sediments are hypothesized to be major sinks of these plastics. Here, over 100 articles spanning the last 50 year are reviewed with following objectives: (i) to evaluate current microplastic extraction techniques, (ii) to discuss the occurrence and worldwide distribution of microplastics in sediments, and (iii) to make a comprehensive assessment of the possible adverse effects of this type of pollution to marine organisms. Based on this review we propose future research needs and conclude that there is a clear need for a standardized techniques, unified reporting units and more realistic effect assessments.
Tipo: Text Palavras-chave: Microplastics; Pellets; Sediment; Techniques; Direct effects; Indirect effects.

The Ethanol Decade: An Expansion of U.S. Corn Production, 2000-09 31
Wallander, Steven; Claassen, Roger; Nickerson, Cynthia J..
The recent 9-billion-gallon increase in corn-based ethanol production, which resulted from a combination of rising gasoline prices and a suite of Federal bioenergy policies, provides evidence of how farmers altered their land-use decisions in response to increased demand for corn. As some forecasts had suggested, corn acreage increased mostly on farms that previously specialized in soybeans. Other farms, however, offset this shift by expanding soybean production. Farm-level data reveal that the simultaneous net expansion of corn and soybean acreage resulted from a reduction in cotton acreage, a shift from uncultivated hay to cropland, and the expansion of double cropping (consecutively producing two crops of either like or unlike commodities on the same...
