“…Los niños son más sensibles a ciertas exposiciones ambientales [14][15][16][17][18] , por tener frecuencia respiratoria más rápida, superficie pulmonar más grande 19,20 , tener una estatura menor que los adultos y realizar actividades como gatear o jugar en el suelo, donde las concentraciones de vapor de mercurio son más altos [21][22][23] . La contaminación del aire en espacios cerrados y exteriores, la insalubridad del agua, la falta de saneamiento y la higiene inadecuada, causan la muerte de 1,7 millones de niños menores de cinco años.…”

Objetivo: Establecer la exposición ambiental a mercurio, para identificar el impacto sobre la salud de la población de niños y adolescentes en cuatro departamentos de Colombia. Metodología: Se llevó a cabo un estudio descriptivo transversal entre 2014-2015, en once municipios de los departamentos de Bolívar, Sucre, Antioquia y Córdoba y dentro de este se realizó un estudio anidado con un grupo de 63 niños y uno de 37 adolescentes de estos municipios. Resultados: El promedio de tiempo de residencia estuvo entre 6 y 9 años y se encontró alta frecuencia de consumo de pescado. El 6,3% de los niños y el 29,7% de los adolescentes, excedieron el límite permisible de mercurio en sangre y el 50,8% de los niños y el 46,0% de los adolescentes excedieron el límite permisible en cabello. En cuanto a los síntomas referenciados por los participantes, hubo diferencia estadísticamente significativa (p>0,05), entre la población de niños y la de adolescentes en salivación excesiva (15,9%), caída del cabello (18,7%), insomnio (29,0%), nerviosismo (19,6%), debilidad (18,0%) y pérdida de memoria (17,3%). Sabor metálico en la boca (8,4%), pérdida de peso (23,4%), temblor (21,5%), problemas de concentración (17,9%) y dolor torácico (17,9%) no mostraron diferencia entre estos dos grupos. Conclusión: Los niños y adolescentes que residen en áreas de explotación de oro o influenciados por la minería de oro, se encuentran expuestos a mercurio, lo que implica un riesgo elevado para su salud.

“…Children are more sensitive to mercury and are at greater risk than adults after certain mercury exposures (ATSDR 1999; Rogers et al 2007). Urine mercury levels < 5 μg/L urine have not been associated with neuro-cognitive effects in children (Bellinger et al 2006; DeRouen et al 2006).…”

“…These practices potentially expose practitioners and their families. Previous reports document the ceremonial mercury use in neighborhoods whose residents are largely Hispanic (John Snow Inc. 2003; Ozuah et al 2003; Rogers et al 2008, 2007; Zayas and Ozuah 1996). Because mercury contamination can persist for years, ceremonial mercury use in the home could also expose future occupants and their children, contributing to health disparities in these populations.…”

ObjectiveConcern for children exposed to elemental mercury prompted the Agency for Toxic Substances and Disease Registry and the Centers for Disease Control and Prevention to review the sources of elemental mercury exposures in children, describe the location and proportion of children affected, and make recommendations on how to prevent these exposures. In this review, we excluded mercury exposures from coal-burning facilities, dental amalgams, fish consumption, medical waste incinerators, or thimerosal-containing vaccines.Data sourcesWe reviewed federal, state, and regional programs with information on mercury releases along with published reports of children exposed to elemental mercury in the United States. We selected all mercury-related events that were documented to expose (or potentially expose) children. We then explored event characteristics (i.e., the exposure source, location).Data synthesisPrimary exposure locations were at home, at school, and at other locations such as industrial property not adequately remediated or medical facilities. Exposure to small spills from broken thermometers was the most common scenario; however, reports of such exposures are declining.Discussion and conclusionsChildhood exposures to elemental mercury often result from inappropriate handling or cleanup of spilled mercury. The information reviewed suggests that most releases do not lead to demonstrable harm if the exposure period is short and the mercury is properly cleaned up.RecommendationsPrimary prevention should include health education and policy initiatives. For larger spills, better coordination among existing surveillance systems would assist in understanding the risk factors and in developing effective prevention efforts.

Differences in cultural and economic status may place ethnic subgroups of children at higher risk for exposure, leading to heightened health risks, and health inequities. Although Latino-Americans represent 22% of all children in the United States, few studies have explored within-group differences in their exposure to toxicants. Using socio-demographic and biomarker data from the National Health and Nutrition Examination Survey from 1999 to 2008, we characterized determinants of health and estimated geometric means of environmental contaminant biomarkers (blood concentrations of lead and mercury, serum concentrations of dichlorodiphenyldichloroethylene [p,p'-DDE] and cotinine, and urinary metabolites of organophosphate [OP] pesticides and polycyclic aromatic hydrocarbons [PAHs]) among 4,257 Mexican American (MA), 677 Other Latino-American (OL), and 3,370 Non-Hispanic White (NHW) children. MAs had the lowest levels of health insurance coverage and regular access to health care, and largest household size compared to NHWs and OLs. MAs had higher levels of p,p'-DDE, lead, and cadmium while OLs had higher estimates of mercury relative to other groups. MAs had higher urinary metabolite concentrations of 2-hydroxynaphthalene; otherwise MAs and OLs had lower concentrations of PAHs. NHWs had higher levels of cotinine and dimethylthiophosphate. For other OP metabolites, differences among groups were less clear. Lead and p,p'-DDE exposure differences likely reflect later and less regulatory control of these chemicals in Latin America. Additionally, poor quality housing with lead paint is more common in economically disadvantaged subpopulations. Dietary habits are possible sources of differential cadmium, mercury, and organophosphate exposure. Cotinine exposure differences by income and U.S.- vs. foreign-born may represent increased acculturation. These results, coupled with additional research on exposure sources may contribute to refinement of environmental health promotion programs for the fast-growing Latino-American population.
