Presencia de metales pesados en leche cruda bovina de Machachi, Ecuador

Abstract: La evaluación de metales pesados en leche puede considerarse como indicador de contaminación ambiental de un lugar, por lo que el objetivo de la investigación fue determinar la presencia de Plomo, Mercurio y Arsénico en leche cruda de Machachi, Provincia de Pichincha-Ecuador. Se recolectaron 58 muestras provenientes de 29 fincas lecheras con sistema de pastoreo extensivo y ubicadas hasta máximo un kilómetro a la redonda del Municipio de Machachi, donde existe actividad industrial y está cerca de la Panamerican… Show more

“…Frequent monitoring of heavy metals in livestock production areas is essential because high concentrations of heavy metals cause anemia, reproductive disorders, cancer, and animal teratogenesis, decreasing long-term production [ 126 ]. On the other hand, consuming food in a contaminated state is a risk factor for human health, as it alters the nervous system's and organs' functions, causing mutagenesis and carcinogenesis [ 127 ].…”
