Impacto ambiental de agroquímicos en los altos Andes merideños Olga Rosa Molina de P. Administración y Contabilidad salud valores ambiente Agricultura agroquímicos La aplicación del paquete de agroquímicos (pesticidas, fertilizantes) a la actividad agrícola desarrollada en los altos Andes merideños venezolanos ha permitido un crecimiento socioeconómico, pero con daños significativos sobre el medio ambiente y la salud humana. Por tanto, el objetivo general de este artículo es, evaluar el impacto ambiental originado por el uso de los agroquímicos en esta región; con base en investigación documental y de campo se procedió a caracterizar la zona de estudio y sus controles respectivos. En segunda instancia, determinar las consecuencias ambientales y de salud que trae consigo la aplicación de los agroquímicos y, tercero, recomendar medidas apropiadas para prevenir riesgos irreversibles a la salud de las personas y al medio ambiente. Finalmente, se concluye esta exposición con la denotación de que la prevención mediante la siembra de valores podría actuar contra tales amenazas, considerando ambas situaciones como mutuamente implicadas. 2012 artículo científico 1317-8822 https://www.redalyc.org/articulo.oa?id=465545893006 es http://www.redalyc.org/revista.oa?id=4655 Visión Gerencial application/pdf Universidad de los Andes Visión Gerencial (República Bolivariana de Venezuela) Num.2
