BACKGROUND: Bioaccumulation of toxic metals in the population is associated with adverse health effects. Although some elements are essential for humans, high levels of exposure can be dangerous. OBJECTIVE: To describe the levels of Inorganic Arsenic (AsIn), Cadmium (Cd), Chromium (Cr), and Mercury (Hg) ...

Resumen: Objetivo: Estimar la prevalencia de niveles elevados (≥5.0μg/dL) de plomo en sangre (PbS) y su asociación con el uso de loza de barro vidriado con plomo (LBVPb). Material y métodos: En 2018 se midió PbS capilar en una muestra representativa de niños de 1 a 4 años de edad reside...
ABSTRACT Objective: It is proposed that in some conditions such as pregnancy and osteoporosis where the bone turnover rate is high, there is mobilization of various minerals including lead (Pb) from bone to blood. This study aimed to determine if there were any differences in serum Pb levels among elder...
Abstract Introduction The literature has reported the association between lead and auditory effects, based on clinical and experimental studies. However, there is no consensus regarding the effects of lead in the auditory system, or its correlation with the concentration of the metal in the blood. Obje...
O objetivo foi avaliar o nível de exposição ao chumbo e mercúrio em população do Pantanal Mato-grossense, Brasil. Chumbo no sangue (Pb-S) (n = 119) e mercúrio na urina (Hg-U) (n = 109) de moradores da região foram determinados por espectrometria de absorção atômica. A comparação de médias e...
Abstract Objective: To investigate blood lead levels in schoolchildren in two areas of Egypt to understand the current lead pollution exposure and its risk factors, aiming to improve prevention politicies. Subjects and method: This was a cross-sectional study in children (n = 400) aged 6-12 years recru...
Introducción. El plomo es neurotóxico para los niños, aun en muy baja concentración sanguínea. Los factores de riesgo (FR) de exposición al plomo no están debidamente identificados en la región de La Plata. Los objetivos fueron determinar la media de plombemia e identificar los FR en niños de 1 ...
La intoxicación por metales pesados puede causar daños múltiples y en ocasiones ausentes de síntomas. En Marzo del 2011 se comienza a analizar la contaminación medioambiental de la localidad de Ventanas, y particularmente de La Escuela la Greda, tras una intoxicación en sus alumnos. Se decidió rea...
The role of lead (Pb) as an environmental cause of nephropathy is difficult to ascertain due to the difficulty to determine clinically its exposure. Aim: To assess lead levels and renal function in a group of males working in mechanical workshops. Material and Methods: Blood and urine samples were obtain...
