“…0.76 mg l 21 vs. 0.65 and 0.24 mg l 21 , respectively. However, it is worth mentioning that the data published by Apostoli et al 19 were estimated by giving to all the undetectable samples theoretical values equal to 0.56LOD, i.e., 0.025 mg l 21 . Although this approach allows more complete information on the lowest ®ndings to be obtained, it results in ranges lower than those achieved excluding all samples below the LOD, as in the present study.…”

In the assessment of human health risk, the obtainment of reference values in biological tissues and/or¯uids is crucial to estimate the type and magnitude of occupational and environmental exposure. In this context, urine is the major excretion route for many noxious substances that have entered the organism and can be viewed as one of the most useful materials for biomonitoring campaigns. In this study, reference concentration ranges for Cr, Ni and V in urine were achieved in a sub-population of 131 youngsters, aged 6±10, attending primary schools in the urban area of Rome. Subjects under drug therapy or affected by any pathological diseases were not included in this investigation. Strict precautions against contamination or loss of the analytes of interest were adopted for all steps. Determinations were performed by means of high resolution inductively coupled plasma mass spectrometry. In general, the natural log-transformed concentration data for the three elements investigated conformed to a satisfactorily normal distribution. The estimated reference ranges were as follows (mg g 21 creatinine): Cr, 0.07±0.76; Ni, 0.20±1.23; V, 0.02±0.22. The sex of the youngsters was tentatively treated as a statistical explanatory variable using the Fischer F-test on variance.

RESUMENFundamento: Entre las posibles emisiones de una planta de valorización energética de residuos sólidos urbanos (PVERSU) se encuentran los metales pesados. el objetivo del estudio es conocer los niveles en sangre y orina de metales pesados en población general de Bizkaia.Métodos: En 2006 se midió la exposición a Pb en 95 muestras de sangre y Cd, Cr y Hg en 93 muestras de orina de adultos de la población general de Bizkaia, País Vasco, obtenidas de dos áreas con alta densidad de tráfico del área metropolitana de Bilbao en la cercanía de una PVERSU que iniciaba su actividad, una tercera correspondiente a una zona urbana de Bilbao con tráfico denso y alejada del área de influencia de las posibles emisiones de la PVERSU y la cuarta alejada de la planta y con baja densidad de tráfico. De cada área se estableció como objetivo elegir a un mínimo 20 participantes, la mitad de cada sexo y, a su vez, la mitad de 20 a 44 años y la mitad de 45 a 69. Se utilizó la prueba de la χ 2 para estudiar la asociación entre variables categóricas. Como prueba de comparación de medias se utilizó la t de Student y la ANOVA para variables con dos o más categorías, respectivamente. Para ajustar factores de confusión se utilizó un modelo de regresión lineal múltiple.Resultados: Las concentraciones medias fueron PbS: 2,68 µg/100ml, CdU 0,54 µg/g creatinina, CrU: 0,51 µg/g creatinina, y HgU: 0,65 µg/g creatinina.Conclusión: No se observaron diferencias entre las zonas. El análisis unifactorial y multifactorial mostró que los niveles de PbS se incrementaban con la edad y estaban asociados con el consumo de productos locales de huerta y con el trabajo en la metalurgia. La edad eleva los niveles de CdU y se observa en clases sociales altas niveles más elevados, así como en mujeres y en personas fumadoras. Los niveles de CrU eran más elevados en zonas alejadas a la PVERSU y en las clases altas. Los niveles de HgU fueron más elevados en mujeres que en hombres.Palabras clave: Metales pesados. Plomo. Cadmio. Cromo. Mercurio. Vigilancia de la población. Incineración. Background: The possible emissions from a municipal urban solid waste treatment plant (MUSWTP) include heavy metals. The purpose of this study is to ascertain the levels of heavy metals in the blood and urine of the general population of Biscay. ABSTRACTMethods: The level of Pb was measured in 95 blood samples (BPb) and Cd, Cr and Hg in 93 urine samples (UCd, UCr, UHg) taken from adults in the general population of Biscay, Basque Country, in 2006. The samples were obtained in two areas with high traffic density in the metropolitan area of Bilbao close to an MUSWTP which had just commenced operation, a third area in downtown Bilbao with heavy traffic and at a distance from the area of influence of possible emissions from the MUSWTP, and a fourth area at a distance from the plant and with low traffic density. The objective was to select a minimum of 20 participants from each area, with an equal number of male and female subjects, and with half the subjects aged between 20 and 44 years...
