Chromated copper arsenate CCA is a wood preservative used for timber treatment since the mid 1930s. It is a mix of chromium , copper and arsenic as Copper II arsenate formulated as oxides or salts. It preserves the wood from decay fungi, wood attacking insects, including termites, and marine borers. It also improves the weather resistance of treated timber and may assist paint adherence in the long term. CCA is known by many trade names, including the worldwide brands Tanalith SupaTimber and Celcure . The chromium acts as a chemical fixing agent and has little or no preserving properties it helps the other chemicals to fix in the timber, binding them through chemical complexes to the wood s cellulose and lignin . The copper acts primarily to protect the wood against decay fungi and bacteria, while the arsenic is the main insecticidal component of CCA. CCA is widely used around the world as a heavy duty preservative, often as an alternative to creosote , and pentachlorophenol . Other water borne preservatives like CCA include alkaline copper quaternary compounds Alkaline Copper Quaternary ACQ , copper azole CuAz , ammoniacal copper zinc arsenate ACZA , copper citrate, and copper HDO CuHDO Recognized for the greenish tint it imparts to timber, CCA is a preservative that has been extremely common for many decades. Over time small amounts of the CCA chemicals, mainly the arsenic, may leach out of the treated timber. This is particularly the case in acidic environments. The chemicals may leach from the wood into surrounding soil , resulting in concentrations higher than naturally occurring background levels. A study found that 12 13 percent of the CCA leached from treated wood buried in compost during a 12 month period. ref Forest Products Journal ref Needs to be more specific.

Only recently defined and acknowledged, it was approved by the International Mineralogical Association IMA in 1969. Bukovskyite was collected a long time ago from the overgrown pit heaps by the inhabitants of Kutn Hora. It was used for poisoning fieldmice and other field vermin.

File Mimetesit mit Kampylit Mineralogisches Museum Bonn 7276 .jpg thumb Mimetite with Campylite Campylite is a variety of the lead arsenate mineral mimetite which received the name from the Greek language Greek kampylos bent, on account of the barrel shaped bend of its crystals. It has also been used as an alternate name for pyromorphite . It occurs in the upper lead deposits through the oxidation of galena or cerussite . The main deposits are Pribam in Bohemia and Dry Gill , Caldbeck Fells , near Wigton , Cumbria , England .
