Los estudios han demostrado que la exposici\u00f3n al plomo es responsable del 0,6 % de enfermedades en todo el mundo, y en una fracci\u00f3n mayor en las \u00e1reas en desarrollo. Se calcula que la exposici\u00f3n al plomo en la infancia contribuye anualmente a unos 600.000 casos nuevos de discapacidad intelectual en ni\u00f1os. Las reducciones en las \u00faltimas dos d\u00e9cadas en el uso de plomo en la gasolina, las pinturas, la fontaner\u00eda y la soldadura han dado lugar a reducciones sustanciales en los niveles de plomo en la sangre.

    Datos b\u00e1sicos sobre el plomo como elemento<\/div><\/div>
    \n\nEl plomo es un elemento blando, muy maleable y d\u00factil. Tiene un color blanco azulado y un aspecto muy brillante. Es muy resistente a la corrosi\u00f3n y a veces se utiliza aleado con antimonio como endurecedor.\n\nEl plomo es un metal altamente t\u00f3xico por inhalaci\u00f3n o ingesti\u00f3n y la exposici\u00f3n a largo plazo puede ser perjudicial. El plomo en su forma elemental se encuentra muy raramente en la naturaleza. Por lo general, se encuentra en forma de galena (PbS) y se extrae mediante un proceso de tostaci\u00f3n. Tambi\u00e9n se encuentra en anglesita, cerusita y minio.\n

    Procesamiento de plomo<\/div><\/div>
    \n\nLa producci\u00f3n principal de plomo comienza con el sinterizado. La mena de plomo concentrada se introduce en una m\u00e1quina de sinterizado con hierro, s\u00edlice, fundentes de piedra caliza, coque, carbonato de sodio, pirita, zinc, c\u00e1usticos o part\u00edculas de control de la contaminaci\u00f3n. La mezcla se expone a aire caliente para quemar el azufre y se env\u00eda a la fundici\u00f3n.\n\nPor lo general, el plomo se funde en un alto horno utilizando el carb\u00f3n de la m\u00e1quina de sinterizado como fuente de calor. A medida que se produce la fusi\u00f3n, se forman varias capas en el horno. La capa de plomo fundido se hunde hacia el fondo del horno. Una capa de los elementos m\u00e1s ligeros, como el ars\u00e9nico y el antimonio, flota en la parte superior y se conoce como el “speis”. A partir del cobre y los sulfuros met\u00e1licos, se forma una capa llamada “mate”. Finalmente, tambi\u00e9n se forma una capa de escoria del alto horno, principalmente formada por silicatos. Por lo general, las capas speis y mate se venden a las fundiciones de cobre donde se refinan para el proceso del cobre. La escoria se almacena y se recicla parcialmente, si el contenido de metal es suficiente.\n

    \n\nEl plomo es uno de los metales m\u00e1s mort\u00edferos que se pueden acumular en el cuerpo durante un per\u00edodo de tiempo hasta causar muchos problemas de salud. El ejercicio y la transpiraci\u00f3n pueden desintoxicar el cuerpo de la acumulaci\u00f3n de metales pesados como el plomo. El plomo no se puede excretar a trav\u00e9s del sistema digestivo. Los \u00f3rganos del cuerpo absorben el plomo directamente de la sangre y lo almacenan junto con otros minerales en los huesos. Desde los huesos, el plomo puede volver a introducirse en el torrente sangu\u00edneo debido a insuficiencia renal, embarazo o menopausia.\n

    Pruebas de plomo<\/div><\/div>
    \n\nExisten tres enfoques principales para determinar el contenido de plomo en las pinturas:\n\n1) Probar la presencia de plomo en la pintura utilizando un kit de an\u00e1lisis qu\u00edmico.\n2) Medir la cantidad de plomo en la pintura in situ utilizando un dispositivo port\u00e1til de fluorescencia de rayos X (XRF).\n3) Recoger una muestra de pintura y medir su contenido de plomo en un laboratorio utilizando diversas t\u00e9cnicas anal\u00edticas\n

    Brief guide to analytical methods for measuring lead in paint<\/h4>\n

    World Health Organization<\/h5>\nwww.who.int <\/a>\n\nThis document provides a brief overview of analytical methods available for measuring lead in paint. It is primarily aimed at informing environmental health personnel and policy-makers who are not laboratory specialists but who may need to develop plans for lead paint testing and abatement programmes …\n\nread more<\/a>\n<\/div>\n\n<\/div>\n\n<\/div><\/li>\n\n

    Efecto del plomo sobre el rendimiento del GI (acero galvanizado)<\/div><\/div>
    \n\nEl plomo no se vaporiza hasta que supera los 1649 \u00b0C y, puesto que es parcialmente soluble en acero, se evapora menos plomo que zinc proporcionalmente. Sin embargo, no se deben inhalar vapores de \u00f3xido de plomo y las pr\u00e1cticas recomendadas siguientes para evitar la inhalaci\u00f3n de vapores de \u00f3xido de zinc tambi\u00e9n evitar\u00e1n la inhalaci\u00f3n de \u00f3xidos de plomo. Tambi\u00e9n existe cierta preocupaci\u00f3n sobre el plomo residual all\u00ed donde los productos galvanizados puedan entrar en contacto con los ni\u00f1os, como cuando se utiliza en equipos para zonas de juegos sin revestimiento superior de alta calificaci\u00f3n. Algunos fabricantes de productos galvanizados utilizan zinc con un nivel de pureza del 99,99 %, por lo que la presencia de plomo no es preocupante a la hora de soldar estos productos o debido al contacto.\n

    Efecto del plomo sobre el rendimiento del PPGI (acero galvanizado prepintado)<\/div><\/div>
    \n\nExiste un volumen sustancial de evidencias hist\u00f3ricas, epidemiol\u00f3gicas y anal\u00edticas que indican que la pintura a base de plomo es la principal fuente de envenenamiento por plomo en ni\u00f1os en Estados Unidos en la actualidad. La v\u00eda principal de exposici\u00f3n parece ser del plomo presente a la pintura hacia el polvo de la casa y el suelo, de ah\u00ed a las manos y, finalmente a la sangre a trav\u00e9s del contacto normal de las manos con la boca. Otra v\u00eda importante es la ingesti\u00f3n directa de virutas de pintura. El peso actual de la evidencia cient\u00edfica indica que la falta de control sobre las pinturas a base de plomo en las viviendas m\u00e1s antiguas dar\u00e1 como resultado la exposici\u00f3n continua al plomo para un gran n\u00famero de ni\u00f1os.\n
