Some Effects of Oil on the Physical and Chemical Characteristics of Wet Tundra Soils

ABSTRACT. Crude hydrocarbons were added to the surface of wet tundra soils at Barrow, Alaska at volumes of 5 and 12 l/m2. Physical and chemical effects in the soil were followed for three years. Soils treated with 5 I/mZ had their chemical and physical properties. little altered. Those treated with...

Description
Summary:ABSTRACT. Crude hydrocarbons were added to the surface of wet tundra soils at Barrow, Alaska at volumes of 5 and 12 l/m2. Physical and chemical effects in the soil were followed for three years. Soils treated with 5 I/mZ had their chemical and physical properties. little altered. Those treated with 12 I/m2 recorded an increase in seasonal thaw, an increase in organlc carbon and an increase in available phosphorus. soil pH shifted toward neutrality. Decreases occurred in water infiltration rate and in plant available cations (Ca, Mg, K). Soil moisture, bulk density, shrinkage percent and total sulphur content appeared unaffected. RGSUMI?. A Barrow en Alaska, du pétrole brut a été répandu en surface sur des Sols de toundra humide, aux taux de 5 et 12 litres au mz. Pendant trois ans, on a suivi les conséquences physiques et chimiques dans le sol. Au taux de 5 litres/m*, les soh traités ont eu leurs propriétés chimiques et physiques peu altérées. Les sols traités sur la base de 12 litres/m2 ont enregistré un accroissement du dégel saisonnier et un accroissement du carbone organique et du phosphore disponible. Le pH du sol est devenu neutre. Le rendement d’infiltration d’eau décroissait comme celui des cations de Plantes disponibles (Ca, Mg, K). L’humidité du sol, sa densité de fmasse, son pourcentage de contraction, et le contenu total en soufre apparaissait sans changement. Traduit par Alain de Vendigies, Aquitaine Co. of Canada Ltd.
