QUÉ SIGNIFICA POLYCHLORINATED BIPHENYL EN INGLÉS
Bifenilo policlorado
Un bifenilo policlorado es un compuesto químico orgánico sintético de cloro unido al bifenilo, que es una molécula compuesta de dos anillos de benceno. Hay 209 configuraciones de organoclorados con 1 a 10 átomos de cloro. La fórmula química para un PCB es C12H10-xClx. 130 de las diferentes disposiciones y orientaciones de PCB se utilizan comercialmente. Los bifenilos policlorados se utilizaron ampliamente como fluidos dieléctricos y refrigerantes, por ejemplo en aparatos eléctricos, fluidos de corte para operaciones de mecanizado, papel carbón y fluidos de transferencia de calor. Debido a la toxicidad ambiental de los PCB y su clasificación como contaminante orgánico persistente, la producción de PCB fue prohibida por el Congreso de los Estados Unidos en 1979 y por el Convenio de Estocolmo sobre Contaminantes Orgánicos Persistentes en 2001. Según la Agencia de Protección Ambiental de EE. Causar cáncer en los animales, y también hay pruebas de que pueden causar cáncer en los seres humanos. Las preocupaciones sobre la toxicidad de los PCB se basan en gran medida en compuestos dentro de este grupo que comparten una similitud estructural y un modo de acción tóxico con la dioxina.
definición de polychlorinated biphenyl en el diccionario inglés
La definición de bifenilo policlorado en el diccionario es cualquiera de un grupo de compuestos en los que los átomos de cloro reemplazan a los átomos de hidrógeno en bifenilo: se usan en la industria en aislantes eléctricos y en la fabricación de plásticos; un contaminante tóxico que puede concentrarse en PCB de tejido animal.
