This study investigates whether different intensities of organic matter removal associated with timber harvest influence decadal-scale storage of soil organic carbon (SOC) and total nitrogen (TN) in the top 1 m of mineral soil 18 years postharvest in a Pinus taeda L. forest in the Gulf Coastal Plain. We quantified forest harvest-related changes in SOC, TN, microbial biomass carbon (MBC), and ni...

In this work, it is studied the removal of atrazine from spiked soils by soil washing using surfactant fluids, followed by the treatment of the resulting washing waste by electrolysis with boron doped diamond (BDD) anode. Results confirm that combination of both technologies is efficient for the removal and total mineralization of atrazine. Ratio surfactant/soil is a key parameter for the remov...

Microcosms were prepared from aquifer material, spiked with monoaromatic hydrocarbons, and amended with oxygen, nitrate, and nitrous oxide. Benzene and alkylbenzenes were degraded to concentrations below 5 micrograms/liter within 7 days under aerobic conditions, whereas only the alkylbenzenes were degraded when either nitrate or nitrous oxide was used. With limited oxygen, monoaromatic hydrocar...

Semi Volatile Organic Compounds (SVOCs) contamination in soil was a widespread problem in China due to industrial pollutants leak and discharge. A pilot study of SVE and related combination techniques was demonstrated for soil contaminated with SVOCs. A miniaturization SVE system was applied in research and performance of this extraction system was measurement. The results of the field test sho...

In situ biosurfactant (rhamnolipid) production by Pseudomonas putida CB-100 was achieved during a bioaugmented and biostimulated treatment to remove hydrocarbons from aged contaminated soil from oil well drilling operations. Rhamnolipid production and contaminant removal were determined for several treatments of irradiated and non-irradiated soils: nutrient addition (nitrogen and phosphorus), P...

Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract Groundwater in the Triassic Sherwood Sandstone aquifer, Liverpool, UK, has locally elevated chloride concentrations (∼4000 mg/l) in parts of the coastal region although there is freshwater right up to the coast line in other areas. The aqu...

Groundwater in the Triassic Sherwood Sandstone aquifer, Liverpool, UK, has locally elevated chloride concentrations (∼4000mg/l) in parts of the coastal region although there is freshwater right up to the coast line in other areas. The aquifer is cut my numerous faults with vertical displacements of as much 300m. SPOT satellite data 5 have been used for the Merseyside area of Liverpool. The sate...

Pseudomonas sp. LAB-08 was isolated from a phenol-fed bioreactor constructed with contaminated aquifer soil as the inoculum. Strain LAB-08 utilized phenol as a sole carbon and energy source. Here, we report the genome sequence and annotation of Pseudomonas sp. LAB-08.

phytoextraction is a remediation technology that uses plants to remove heavy metals from soil. the success of a phytoextraction process depends on adequate plant yield (aerial parts) and high metal concentrations in plant shoots. a pot experiment was conducted to investigate the combination effects of plants [sunflower (helianthus annuus) and canola (brassica napus)] with soil treatments (manur...

Geologic heterogeneity is one of the important factors controlling migration and distribution nonaqueous phase liquids in subsurface. Heterogeneity, such as fractures, complicates effectiveness environmental remediation, uncharacterized aquifer causes significant uncertainties removal liquids. Foaming an injection gas effective method to alleviate challenges accessing heterogeneous media during...
