Toxicity Of Aspen Wood Leachate To Aquatic Life: Laboratory Studies, Barry R. Taylor, J. Stephen Goudey, N. Bruce Carmichael

Aspen Bibliography

Trembling aspen (Populus tremuloides Michx.), a common hardwood tree throughout Canada, is being harvested at increasing rates for use in paper and building materials. Piles of aspen logs have been observed to produce a dark, watery, acutely toxic leachate. A laboratory study was undertaken to elucidate the nature, strength, and persistence of aspen leachate toxicity and the chemical composition of the leachate. Leaching from aspen chips in the laboratory was rapid, with 1% mass loss in the first 24 h. Another 2 weeks of immersion was necessary to remove all remaining leachable material (3% total)> Fresh aspen leachate derived …

Sorting Aspen Bolts And Drying Aspen Flitches For Sdr, R.S. Boone

Aspen Bibliography

Log sorting is necessary when processing aspen saw-dry-rip (SDR) to select optimum log diameter and to minimize number of logs with dark-colored centers. Wetwood, which is difficult to dry, is commonly associated with these dark centers. SDR processing involves drying 7/4- to 8/4-thick live-sawn flitches. Drying the flitch and then sawing studs produces straighter studs than sawing first and drying in stud form. High-temperature kiln drying (230 o F to 240 o F) has given good results with several species (such as, basswood and yellow-poplar). For species likely to contain wetwood (aspen, cottonwood, willow), high-temperature drying is not recommended. A …

Aspen For Cabin Logs, Albert W. Sump

Aspen Bibliography

A plentiful supply of pine and cedar logs provided the early settlers of this country with a cheap and durable material for the construction of their homes and farm buildings. Only the axe and the ingenuity of the pioneer were needed to erect a shelter against the elements of nature. Early in the 19th century, the circular saw came into use resulting in a change in building construction. The pine stands in New England and in the Lake States, considered inexhaustible in the 19th century, were converted to lumber to construct buildings necessary for the rapid development of the country. …
