Diseño de un protocolo de cuantificación de niveles de arsénico en muestras de uñas en química forense.

Abstract

Arsenic is going to be found in water, soil and food, this will affect around 4.5 million people around the world, causing notable affections in the organism until death, therefore we have developed a protocol based on quantification techniques of arsenic in nail samples through the compilation of bibliographic data sources based on scientific data, since this investigation was descriptive on the subject under study and wants to represent both forensic chemistry and forensic experts, which is the science in charge From the detection of the presence of a chemical such as arsenic which is a metalloid, among other substances such as drugs that cause poisoning, arsenic in concentrations greater than 50 ug / L is lethal in the person, which will affect the heart system, lungs, liver damage and cancer. Among the investigated techniques, the following stand out: cyclic voltammetry technique, x-ray fluorescence technique, atomic absorption spectrophotometer, through the aforementioned techniques we obtain the quantification protocol that in detail would be: collection, washing, digestion, transport and conservation of the nail sample for a full scientific study.
