The research lines mentioned before, are supported by the development of analytical methodologies, among them:
Sample pretreatment techniques that prevent organic
solvents use (SPME). Different derivatization techniques on
sample, fiber, injector, etc., are being used to broaden the
organic pollutant range to include ionic and polar ones.
Analytical techniques development for the determination
of emergent organic and organometallic pollutants: perfluorinated, pharmaceuticals, Hg and their organic species (e.g.methylmercury), endocrine disruptors, etc.
Development of molecular tracers for pollutants associated to anthropogenic activities.
Accelerated solid extraction: pressurized and heated
solvents; supercritical fluids in the determination of organic
and organometallic pollutants in soils and sediments. The degree
of matrix interaction of the pollutant has been characterized
from extraction conditions
Evaluation of human exposure degree to pollutants: use of hair as an indicator of human exposure to methylmercury.
