N2 - Fish tissues were analyzed directly with an X-ray photoelectron spectroscopy (XPS) system in order to find pollutant elements that may be bioaccumulated in the fish’s body in a river that is in contact with the mining industry. XPS method could be used as a first technique to find a wide gamma of elements before using conventional methods. Fish tissue was homogenized in order to make it able to be analyzed by a surface analysis, Whole fishes were analyzed by two homogenizing methods: incineration at 350ºC, and by dehydration and crushing in a ball mill. Both methods tested show different results in the same samples. It has been observed that in the incinerated samples the bonding energy is more intense, this could be a result of the elements’ oxidation due to the combustion. Other difference is that in the incinerated samples there are some elements that are not shown in the dehydrated samples. Because of this, we suggest that the incineration should be the adequate technique to continue analyzing this kind of materials.
