Download or read book Heavy Duty Wood Preservatives written by Canada. Pest Management Regulatory Agency and published by . This book was released on 2010 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Proposed Re-evaluation (PRVD) summarizes the science evaluation for creosote, pentachlorophenol, chromated copper arsenate and ammoniacal copper zinc arsenate and presents the reasons for the proposed re-evaluation decision. It also proposes additional risk-reduction measures to further protect human health and the environment. The information is presented in two parts: i) the Overview describes the regulatory process and key points of the evaluation (i.e. the Science Evaluation summary); ii) while the full Science Evaluation provides detailed technical information on the human health, environmental and value assessments of creosote, pentachlorophenol, chromated copper arsenate and ammoniacal copper zinc arsenate. Though the PRVD is a consultation document, consultation has already taken place on the science evaluation and risk assessment component of these re-evaluations.--Document.

Book excerpt: The re-evaluation of Heavy Duty Wood Preservatives (HDWPs) granted continued registration to creosote, pentachlorophenol, chromated copper arsenate and ammoniacal copper zinc arsenate subject to conditions that included the addition of new risk-reduction measures to product labels and additional data requirements. The Risk Management Plan is a plan to identify and implement opportunities to lower potential exposures and further reduce risk, above and beyond changes to product labels resulting from the Pest Management Regulatory Agency's HDWP re-evaluation.--Includes text from document.

Book Synopsis Assessment of the Environmental Effects Associated with Wooden Bridges Preserved with Creosote, Pentachlorophenol, Or Chromated Copper Arsenate by : Kenneth M. Brooks
Download or read book Assessment of the Environmental Effects Associated with Wooden Bridges Preserved with Creosote, Pentachlorophenol, Or Chromated Copper Arsenate written by Kenneth M. Brooks and published by . This book was released on 2000 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Timber bridges provide an economical alternative to concrete and steel structures, particularly in rural areas with light to moderate vehicle traffic. Wooden components of these bridges are treated with chromated copper arsenate type C (CCA), pentachlorophenol, or creosote to prolong the life of the structure from a few years to many decades. This results in reduced transportation infrastructure costs and increased public safety. However, the preservative used to treat the wooden components in timber bridges is lost to the environment in small amounts over time. This report describes the concentration of wood preservatives lost to adjacent environments and the biological response to these preservatives as environmental contaminants. Six bridges from various states were examined for risk assessment: two creosote treated bridges, two pentachlorophenol-treated bridges, and two CCA-treated bridges. In all cases, the largest bridges located in biologically active environments associated with slow-flowing water were selected to represent worst-case analyses. Sediment and water column concentrations of preservative were analyzed upstream from, under, and downstream from each bridge. The observed levels of contaminant were compared with available regulatory standards or benchmarks and with the quantitative description of the aquatic invertebrate community sampled from vegetation and sediments. Pentachlorophenol- and creosote-derived polycyclic aromatic hydrocarbons (PAHs) were not observed in the water near any of the selected bridges. However, low levels of PAHs were observed in the sediments under and immediately downstream from these bridges. Pentachlorophenol concentrations did not approach toxicological benchmarks. Sediment concentrations of naphthalene, acenaphthylene, and phenanthrene exceeded the probable effect level. Metal levels at the bridges treated with CCA were less than predicted effect levels, in spite of questionable construction practices. Adverse biological effects were not observed in the aquatic invertebrate community or laboratory bioassays conducted on water and sediments sampled at each of the bridges. Results of this study reveal the need to follow the construction information found in Best Management Practices for the Use of Treated Wood In Aquatic Environments published by Western Wood Preservers Institute. Regulatory benchmarks used in risk assessments of this type need to be indexed to local environmental conditions. The robust invertebrate communities associated with slow-moving streams over soft bottoms were not susceptible to the concentrations of PAHs that would be expected to affect more sensitive taxa, which typically are located in faster moving water over hard bottoms. Contaminants released from timber bridges into these faster systems (where more sensitive taxa are located) are significantly diluted and not found at biologically significant levels.
