Chromated copper arsenate (CCA) is a wood preservative containing compounds of chromium, copper, and arsenic, in various proportions. It is used to impregnate timber and other wood products, especially those intended for outdoor use, in order to protect them from attack by microbes and insects.

2024年12月26日 · Chromated copper arsenate (CCA) is a wood preservative pesticide containing chromium, copper, and arsenic that protects wood against termites, fungi, mites and other pests that can degrade or threaten the integrity of wood products.

What is CCA-treated wood? If your residential wood structure was built before 2004 and is not made of cedar or redwood, it was most likely constructed with wood pressure-treated with Chromated Copper Arsenate (CCA). CCA is a chemical preservative comprised of arsenic, chromium, and copper.

2024年5月13日 · Using recycled CCA-treated wood in garden beds can leach chromium, copper, and arsenic into the surrounding soil. Residues could get on plants, especially root vegetables. Plants may take up arsenic or other chemicals through their roots and into their tissue, although the amount is typically low.

Seventy years of safe use and the body of sound scientific and medical evidence demonstrate that chromated copper arsenate (CCA) pressure treated wood is safe when used as recommended. The US EPA currently is re-evaluating CCA as part of a mandated reregistration process applicable to all pesticide products.

CCA is a preservative containing arsenic, chromium and copper. It is used for the long-term protection of wood against attack by fungi, insects and marine borers. Applying wood preservatives extends the productive life of wood, and helps reduce demand for forest resources.

Chromated copper arsenate (CCA) is a wood preservative that contains chrome, copper, and arsenic, in various proportions. It is a water-soluble inorganic pesticide used to make wood resistant to attack by termites and fungi that cause decay.

Chromated copper arsenate (CCA) is a wood preservative pesticide containing chromium, copper, and arsenic that protects wood against termites, fungi, mites and other pests that can degrade or threaten the integrity of wood products.

Chromated copper arsenate (CCA) is a pesticide that has been used as a preservative in pressure-treated wood since the 1940s. When injected into the wood, CCA protects it from rotting due to decay-causing insects and microbes.

Arsenic-treated wood is the result of a chemical process in which wood is treated with a pesticide/preservative called chromated copper arsenate (CCA) to prevent rotting in lumber designed for outdoor use.
