ABSTRACT

Objetivo: La exposición crónica a plaguicidas no persistentes se ha relacionado con diversas patologías crónicas; sin embargo, pocos estudios han evaluado la exposición a plaguicidas no persistentes en población española. Métodos: En 2007 se determinó la presencia de 24 plaguicidas mediante cromatografía de gases/espectometría de masas en 363 muestras de suero de adultos no laboralmente expuestos de Tenerife. Resultados: El 99,45% presentaron residuos (6 ± 2 plaguicidas/muestra). Los plaguicidas más frecuentes fueron piretroides (96,1%), organofosforados (93,9%) y organoclorados (92,3%). En el 81% de los sujetos se detectaron bifentrina y malatión, considerados neurotóxicos, y en el 50% hexaclorobenceno, DDT y buprofezina. El malatión, un "obesógeno ambiental", se detectó en el 82%, y plaguicidas considerados "disruptores endocrinos" en el 97,2% de las muestras. Conclusiones: Existe una exposición inadvertida a plaguicidas no persistentes que puede afectar a la salud de nuestra población, por lo que se hace necesario incluirlos en los estudios de monitorización (AU)


Objective: Chronic exposure to non-persistent pesticides (NPPs) is of concern because these substances have been associated with chronic diseases. However, few studies have addressed chronic exposure to NPPs in Spanish populations. Methods: We determined the presence of 24 pesticide residues by gas chromatography/mass spectrometry in 363 serum samples obtained from non-occupationally exposed adults from Tenerife island in 2007. Results: Most of the samples (99.45%) showed detectable residues (6 ± 2 pesticides per sample). The most frequently detected pesticides were pyrethrins (96.1%), organophosphates (93.9%) and organochlorines (92.3%). The neurotoxicants bifenthrin and malathion were detected in 81% of the samples and hexachlorobenzene DDT and buprofezin in more than 50%. Malation, an "environmental obesogen", was detected in 82%, and "endocrine disrupter" pesticides were present in 97.2% of the samples. Conclusions: Because there is clear, continuous and inadvertent exposure to NPPs that may be inducing adverse effects on human health, NPPs should be included in biomonitoring studies (AU)
