Complexation of iron (Fe) by organic compounds as well as reductive dissolution are potentially important Fe dissolution processes in organic-rich soils such as Aquods. The objectives of this study were to develop a method to sample Aquod water table

Like other states in the U.S., New Hampshire is adopting the Phosphorus Site Index approach for agricultural areas. While the status of phosphorus (P) in New Hampshire's agricultural soils had not been investigated thoroughly, a majority of soil samp

Arsenic toxicity and mobility in soil and aquatic environments depends on its speciation, with reducing environments generally leading to more hazardous conditions with respect to this element. Aqueous sulfide (H2S or HS-) is a strong reductant and o

Mining activities and arsenical pesticide applications can introduce arsenate compounds into soils and sediments. Under water-saturated (flooded) soil conditions, arsenate solids are subjected to biotically generated reducing conditions and may under

Supercritical fluid extraction (SEE) recoveries of 2,4-D (2,4-dichlorophenoxyacetic acid) from spiked Washington soils depended on both pH and organic matter content. The soils used in this study spanned a wide range of organic C concentration (2-480

Supercritical carbon dioxide (SF-CO 2 ) has been recently introduced for use in determining sorption coefficients of atrazine (6-chloro-N-ethyl-N′-(1-methyl)-1,3,5-triazine-2,4-diamine) in field-moist soils. In this study we determined the effects

Interest in using supercritical CO2 as an alternative to nonpolar liquid solvents to extract toxic organics from soils is growing. Unfortunately, supercritical CO2 alone is a poor solvent for many polar compounds, including acid herbicides, in soils.

Supercritical fluid extraction (SFE) with carbon dioxide (SF-CO 2 ) has been used effectively as a method for the extraction of pesticides from soils. This study was intended to test its potential as a means of removing atrazine from soil water for q

Supercritical fluid extraction (SFE) with CO 2 , a clean and rapid alternative to conventional organic solvent extraction techniques, was investigated for the extraction of 2,4-D from soils using a variety of pre-extraction soil treatments to enhance
