| description | Pentachlorophenol (PCP) and its salt, sodium pentachlorophenate (NaPCP) are very persistent halogenated hydrocarbons with a wide spectrum of toxicity and which are used primarily to protect timber from fungi, bacteria and insects. PCP and NaPCP are chemicals with a high acute toxicity to human beings increased substantially by impurities such as c h l o r o d i b e z o d i o x i n s a n d chlorodibenzofurans. PCP has long term adverse effects, is mutagenic, causes alterations in immunological and endocrine systems; it increases susceptibility to infections and reproductive dysfunction. There are several studies on the adverse effects of these substances on human and ecosystems health caused by its persistence, bioaccumulation potential and the toxicity of the impurities. These works are the technical basis of the severe restrictions or even total ban status of PCP and its derivatives and residues in several countries. In Mexico, PCP is authorized for forest, urban and industrial applications as a wood preserver. PCP must be purchased and used only by or with the surveillance of a certified technician. There is a significant lack of information among people about the environmental and health risks from the misuse and inadequate disposal of PCP, NaPCP and its residues. The aim of this work is to diffuse the available technical information on this subject and recommend the application of the national and international legislative regulations on PCP use. |

El pentaclorofenol (PCP) y su sal sódica, el pentaclorofenato de sodio (NaPCP), son hidrocarburos halogenados de amplio espectro de toxicidad, muy persistentes, usados para la preservación de la madera contra hongos, bacterias e insectos. El PCP y el NaPCP son sustancias de alta toxicidad aguda para humanos que aumenta por la presencia de impurezas como las clorodibenzodioxinas y los clorodibenzofuranos. El PCP tiene graves efectos a largo plazo: es mutágeno, causa alteraciones en los sistemas inmunológico y endocrino, aumenta la susceptibilidad a infecciones y altera las funciones reproductivas. Existen numerosos estudios sobre los efectos adversos de estas sustancias en la salud humana y de los ecosistemas causados por su toxicidad, persistencia, capacidad de bioacumulación y por la toxicidad de sus impurezas. Estos estudios son la base técnica para que el PCP y sus derivados estén severamente restringidos o totalmente prohibidos en numerosos países. En México, el PCP está autorizado para usos forestal, urbano e industrial como preservador de madera; su venta debe estar restringida y su aplicación y manejo deben hacerse bajo la responsabilidad de un técnico autorizado. Existe mucha desinformación entre la población acerca de los riesgos que representa para la salud y el ambiente, el manejo inadecuado de estas sustancias y de sus residuos, por lo que este trabajo pretende difundir la información técnica que existe sobre este tema y recomendar la aplicación de las normas y regulaciones nacionales e internacionales aplicables al manejo de esta sustancia.
