Using natural soil components to trap pollutants will allow producers to control soil contaminants and reuse draining water while protecting their agricultural crops, according to Mohamed Elsayed, a Fulbright Postdoctoral Scholar at South Dakota State University’s chemistry and biochemistry department. His research seeks to increase the ability of humic acid to adsorb, or trap pollutants, in combination with either of two clay minerals—kaolinite or montmorillonite.

First Direct Observation of Carbon Dioxide’s Increasing Greenhouse Effect at the Earth’s Surface

View | Comment

Scientists have observed an increase in carbon dioxide’s greenhouse effect at the Earth’s surface for the first time. They measured atmospheric carbon dioxide’s increasing capacity to absorb thermal radiation emitted from the Earth’s surface over an eleven-year period at two locations in North America. They attributed this upward trend to rising CO2 levels from fossil fuel emissions.
