Pyrene and chrysene fate in surface soil and sand microcosms

Environmental Toxicology and Chemistry, 2001
Abstract Polycyclic aromatic hydrocarbons (PAHs) are major components of wastes from municipal gas plants and many wood preservatives. Soil contaminated with these wastes is a potential threat to human health because of the carcinogenicity of many PAHs.

Sorption of a Dispersed Dye by Sand and Soil

Journal of Environmental Quality, 1979
AbstractThe sorption of monoazo dye (a dispersed dye) by sand and calcareous soil is evaluated by laboratory batch and column tests for the purpose of obtaining quantative information needed for disposing of dyeing effluent. In the batch tests, the soil samples were added to dye solutions (or dispersions) having a concentration range of 25 to 125 mg ...

Sand Mineralogy of Some TamilNadu Soils

MADRAS AGRICULTURAL JOURNAL, 1975
A study of the sand mineralogy of some typical soils representing black.red alluvial and laterite series of TamilNadu has been takenup to understand the nature of parent material.degree of weathering and also the fertility status.The minerals wer identified and ounted using standard properties .The mineralogical make up of the soil samples studied ...

Chain-Soil Interaction in Carbonate Sand

Offshore Technology Conference, 2016
Abstract The design of mooring anchors of Floating LNG systems on Australia's North West Shelf (NWS) is challenging due to the high mooring loads and the seabed which comprises carbonate soils. Anchors with an embedded padeye require engineering of the chain inverse catenary and management of interfaces between the anchor and mooring ...

Soil Plug Behavior of Piles in Sand

Offshore Technology Conference, 1990
Abstract It has been proposed by Randolph (2) that granular soil plugs in open ended pipe piles can develop much greater resistances than allowed in present design (3). A simple mathematical model extending Randolph's concept to include load deformation behavior was developed and checked against more sophisticated ...

Soil Aggregate Abrasion by Impacting Sand and Soil Particles

Transactions of the ASAE, 1984
ABSTRACT DURING wind erosion, erodible particles (< 0.85 mm diameter) are removed continually in saltation and suspension, but the supply of particles is rarely exhausted because new erodible-size particles are created constantly by abrasion. Little is known about the physics of soil abrasion, however. This study was undertaken to determine the effects

A Lithochronosequence of Soils Formed in Dune Sand

Soil Science Society of America Journal, 1981
Abstract In western Indiana, soils on sand dunes range in development from those with only a weak color B horizon to those with a strongly developed argillic horizon. For this study, five soil sites exhibiting various degrees of soil development were described and analyzed. The most strongly developed soils were on older land surfaces,

Expansive Soil Improvement with Weathered Sand

ICTE 2013, 2013
An innovative modification method by adding weathered sand into expansive soil was proposed based on the characteristics that the expansive soil would swell and shrink with super-hydrophilic property and low-permeability under the condition of increasing and decreasing water content, respectively.

SOIL AGGREGATION BY CRYPTOGAMS OF A SAND PRAIRIE

American Journal of Botany, 1985
Cryptogam‐covered, sandy soils of the Big Sand Mound prairie in southeastern Iowa are significantly more aggregated than bare soils. Soil particles covered by moss are intertwined by rhizoids, whereas cyanobacteria and lichen fungal hyphae adhere to the particles and glue them together.

Efficiency of sanding and claying of peat soils

Zemleustrojstvo, kadastr i monitoring zemel' (Land management, cadastre and land monitoring)
The study has established the influence of various doses and types of mineral components (sand and clay in the raw, and in combination with mineral fertilizers) on the waterphysical properties of peat soils and positive changes in such characteristics as: volume weight, specific gravity, total porosity, total moisture capacity, soil hardness.
