Intensive studies of DDT residues in forest soil.

چکیده

Approximately 6,000 tons of technical DDT were sprayed over i0 million acres of forest land around New Brunswick (N.B.), Canada, between 1952 and 1968, as part of the regional spruce budworm (Choristoneura fumiferana Clemens) control program (MACDONALD, 1966). Intensive ecological research on DDT in the forest environment has been concentrated around the Priceville area of Central N.B. since 1966 (MACDONALD and DUFFY, 1968). The 1,050 acre Priceville plot was selected to represent the locality having the heaviest DDT-dosage record for N.B. forests, namely 70 ounces (oz.) per acre applied between 1956 and 1967.

DDT residues in forest floors and soils of western Oregon, September-November 1966.

Between 1945 and 1965, 1.82 million hectares, or about 17 percent of the total commercial forestland in Oregon, were treated with 2.02 million kg DDT. Detectable residues of this insecticide might be present in forest soils, even those which have never received a direct application of insecticide. Forest floor and mineral soil samples were collected along four east-west transects across the Coa...

Effects of Soil Oxygen Conditions and Soil pH on Remediation of DDT-contaminated Soil by Laccase from White Rot Fungi

High residues of DDT in agricultural soils are of concern because they present serious threats to food security and human health. This article focuses on remediation of DDT-contaminated soil using laccase under different soil oxygen and soil pH conditions. The laboratory experiment results showed significant effects of soil oxygen conditions and soil pH on remediation of DDT-contaminated soil b...

DDT Persistence and Volatility as Affected by Management Practices after 23 Years

In 1971, an experiment was conducted in a field containing high amounts of residual DDT (dichlorodiphenyltrichloroethane) to evaluate deep plowing, followed by flooding, with and without organic matter applications, as soil and water management tools to reduce total DDT residues and preferentially degrade the residual DDT to DDD [l,l-dichloro-2,2-bis (p-chlorophenyl) ethane]. The experimental s...

Forest soil carbon is threatened by intensive biomass harvesting.

Forests play a key role in the carbon cycle as they store huge quantities of organic carbon, most of which is stored in soils, with a smaller part being held in vegetation. While the carbon storage capacity of forests is influenced by forestry, the long-term impacts of forest managers' decisions on soil organic carbon (SOC) remain unclear. Using a meta-analysis approach, we showed that conventi...

Dynamic nitrogen deposition thresholds during forest stand development in a Douglas fir forest analysed with two nitrogen models SMART2 and MERLIN

In contrast to the classical critical load (CL) concept, based on long-term steady state conditions, a dynamic deposition threshold (DDT) is introduced. This DDT takes into account all relevant dynamic aspects of vegetation development/forest growth, mineralisation, immobilisation and denitrification, depending on the successional stage of the forest. DDT values for nitrogen were determined for...
