Abstract

The levels of copper, zinc, and arsenic in soil surrounding Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] utility poles treated with ammoniacal copper zinc arsenate (ACZA) were investigated at sites in Florida, Virginia, and New York. Copper levels were elevated near the poles and declined with both horizontal distance away from the pole and depth beneath the soil surface. Zinc levels were also elevated next to the poles, but the levels declined more slowly than did those of copper. Arsenic levels were elevated in soil immediately next to the poles but declined to near background levels farther away. The results indicate that metals can leach from ACZA-treated poles, but do not migrate far in the soil, and thus the levels decline sharply with distance from the poles.

摘要

在佛罗里达州、弗吉尼亚州和纽约州的一些地点，对用氨化铜锌砷酸盐（ACZA）处理过的花旗松[北美黄杉（Pseudotsuga menziesii (Mirb.) Franco）]电线杆周围土壤中的铜、锌和砷含量进行了调查。电线杆附近的铜含量升高，并且随着与电线杆水平距离的增加以及土壤表面以下深度的增加而下降。电线杆旁边的锌含量也升高了，但下降速度比铜慢。紧邻电线杆的土壤中砷含量升高，但在较远的地方下降到接近背景水平。结果表明，金属可以从经ACZA处理的电线杆中浸出，但在土壤中迁移不远，因此含量随着与电线杆距离的增加而急剧下降。
