“…Lyytikäinen et al (2001) have reported the bioaccumulation of arsenic, but not chromium or copper, in worms (Lumbriculus variegatus) exposed to sawmill sediments containing residues of CCA. Lebow et al (1999) cited release rates of 0.007-0.032 µg cm −2 day −1 for chromium 0.17-0.95 µg cm DeGroot et al (1979) measured the distribution gradients of arsenic and chromium in fine sandy loam soil around and below CCA-treated southern pine stakes. From their measurements, they concluded that there was no significant contribution of arsenic or chromium to the surrounding soil or water.…”

A recent agreement between the United States Environmental Protection Agency (USEPA) and the wood-treating industry will result in a phase-out of building timbers preserved with chromated copper arsenate (CCA). This agreement was motivated by a desire to reduce exposure to arsenic in the production, utilization and disposal of such material. The leaching of chromium, copper and arsenic from CCA-treated building timbers into water and soil and the subsequent environmental effects have been reviewed, as have the laboratory and epidemiological studies on the toxicology of CCA-treated building timbers. The benefits of the phase-out agreement are questionable because much arsenic will remain in the environment, and the alternatives to wood preservation with CCA are not without environmental consequences.

“…Tests of poles treated with pentachlorophenol in P9 Type‐A oil showed little evidence of preservative migration more than 300 mm from the poles (Muraka et al, 1996). Mortimer (1991) found little evidence of movement of metals from poles treated with CCA amended with polyethylene glycol, while other work noted substantial metal levels at the groundline immediately adjacent to CCA‐treated poles and treated stakes (Cooper et al, 2001; Cooper and Ung, 1997; DeGroot et al, 1979; Zagury et al, 2003); however, there is little information on the movement of metal components from ACZA‐treated wood.…”

Copper, Zinc, and Arsenic in Soil Surrounding Douglas‐Fir Poles Treated with Ammoniacal Copper Zinc Arsenate (ACZA)

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.

“…Studies of the movement of CCA constituents in soils generally agree that the constituents are not highly mobile, although some movement of arsenic may occur in sandy soils (De Groot et al 1979, Bergman 1983, Brown 1986, Bergholm and Dryler 1989, Bergholm 1990, Murphy and Dickinson 1990, Lund and Fobian 1991, Holland and Orsler 1995. Movement of both copper and chromium in soil is limited by their strong reactivity with organic soil components (Bergholm 1990, Lund andFobian 1991), while arsenic retention in soil is more influenced by the presence of iron, aluminum, and clay (Fordham andNorrish 1974, Frost andGriffin 1977).…”

Environmental accumulation of preservative adjacent to a chromated copper arsenate (type C)-treated wetland boardwalk was evaluated. The site is considered a realistic ''worst case'' because of the large volume of treated wood, low current speeds, high annual rainfall, and environmental sensitivity. Soil and sediment samples were collected before construction and 0.5, 2, 5.5, 11, 24, 60, and 131 months (11 y) after construction and analyzed for total chromium, copper, and arsenic concentrations. This article updates the findings after 11 years of exposure. Environmental concentrations varied with time, with proximity to the treated wood, and between riparian and aquatic locations. Concentrations of leached components in the soil developed slowly, were greatest at the 60-month sampling, and declined at the 131-month inspection. Soil samples with elevated levels of copper and chromium were confined to directly under the drip line of the boardwalk, and arsenic appeared to be limited to within 0.3 m (1 ft) of the structure. Concentrations of leached components in the sediments increased more quickly than those in the soil and tended to reach maximum or near maximum levels within the first year. However, concentrations of arsenic and copper in sediments directly under the walkway reached maximum levels after 60 months, before declining at the 131-month sampling. Elevated concentrations of copper, chromium, and arsenic were occasionally found in sediments as much as 3 m (10 ft) from the boardwalk.
