11. TOXICOLOGICAL INFORMATION



Carcinogenicity Data: IARC has classified untreated hardwood and hardwood/softwood mix wood dust as a Group I human carcinogen.= The wood dust classification is ba= sed primarily on IARC’s evaluation of increased risk in the occurrence of adenocarcinomas of the nasal cavities and paranasal sinuses associated with occupational exposures to untreated wood dust. NTP has classified all untreated w= ood dust as a carcinogen.   <= o:p>

&nb= sp;

A human = health risk assessment has been conducted in accordance with U.S. Environmental Protection Agency (EPA) risk assessment guidance in order to evaluate human health risks associated with exposures to Copper Azole Type B (CA-B) treated wood. Four different scenario= s, including occupational (adult builders), resident handler (adult female), subchronic (child) and chronic (child to adult) residential, and playground (child and teenager) were evaluated. Exposures evaluated in the risk assessment include incidental ingest= ion and dermal contact with dislodgeable residue from the surface of CA-B treat= ed wood and soil impacted with tebuconazole (TEB) and copper, inhalation of sawdust from CA-B treated wood, and inhalation of re-suspended soil particulate. Non-cancer health risks are expressed as margin of exposure (MOE), which is a ratio of the no observed effect level (NOEL) or the lowest observed effect level (LOEL) for= a constituent, to an estimated exposure level for the constituent. The greater the MOE, the less like= ly that exposure to the constituent will pose a potential health risk. Based on the evaluation, the lowes= t MOE of 170 is for incidental ingestion of copper in the soil for the child resi= dent (ages 1-6 years). Based on EPA guidance, an MOE of 10 is the benchmark for this exposure route. Thus, no adverse health effects are expected. Most of the MOEs calculated in the risk assessment are greater than 1,000, and therefore, no= ne of the exposures to TEB or copper evaluated pose a potential health risk. Cancer risks were not assessed bec= ause according to EPA, neither TEB nor copper is a known or probable carcinogen.=

      12. ECOLOGICAL INFORMATION=

Copper A= zole treated wood leaching studies were conducted for 30.5 days on commodity size products in dynamic test cylinders using diluent water at nominal temperatu= res of 5, 15, and 25 degrees C and pH of 5.5, 7.0 and 8.5. Samples collected on days 1.5, 2.5= , 4.5, 7.5, 10.5, 15.5, 22.5, and 30.5 were analyzed for total copper and tebucona= zole (TEB). The treated wood was t= hen leached for an additional 307.6 to 386.8 days in an experimental pond to confirm long term preservative loss rates.= A suite of bioassays were conducted on day 0.5 effluent. Copper and TEB loss rates declined exponentially with time and appeared to reach steady state losses at the en= d of about week 3. Predictive equa= tions describing these loss rates, for use in developing a risk assessment model, were developed using non-linear regression analysis. Bioassay results indicated that environmental risks associated with CA-B preserved wood can be evaluated so= lely on copper predictions and water quality criteria for copper. The TEB did not add to the toxicit= y of the effluent. In fact, it app= ears that the increased dissolved organic carbon associated with TEB and wood extractives reduced the copper’s toxicity in the effluent. These studies were conducted at di= lution water flow rates much lower than could be anticipated in open aquatic envir= onments. Dilution factors in very slow flow= ing streams or lakes, where current speeds might be as low as 1.0 cm/sec, are 4= 68 times higher than the flows created in these tests.

&nb= sp;

Prelimin= ary modeling indicates that a pier sitting on 25 CA-B treated piling in freshwa= ter flowing at a very low current speed of 2.0cm/sec (typical of many small lak= es) would increase the copper concentrations by 0.28 µg Cu/L at pH 6.5. This suggests that CA-B preserved = piling can be used in most surface waters that do not closely approach or exceed E= PA water quality criteria. Howev= er, the models will provide a basis for conducting site specific risk assessments where large volumes of treated wood= are proposed for immersion in poorly circulating bodies of water.
