“…Concentrations of Cd in teeth BH3 and BH4 were markedly lower than other recent studies. 34 This was likely due to the low exposure to Cd in the rural community where the participants resided, further suggesting that Cd concentrations in teeth, although low, are most likely governed by environmental exposure.…”

Elemental bio-imaging employing LA-ICP-MS is a novel method for constructing μm-scale maps of trace elements in teeth. This simple imaging method displays the heterogeneity of trace elements throughout the tooth structure that correspond to specific structural and developmental features of teeth. As a preliminary study, this work demonstrates the capabilities of LA-ICP-MS imaging in dental research.

“…As regards to bioaccumulation in humans, Arruda-Neto et al (2010) reported a strong correlation between individual age and bioaccumulation of Nickel, indicating that bioaccumulation is more intense in the childhood period (7-10 years), followed by a decrease (clearance) between 10-20 years, the formation of a plateau at ages between 20 and 50 years old and another decrease for ages over 60 years.…”

Literature data on Chromium show that trivalent chromium has low acute and long term toxicity whilst hexavalent chromium is acutely toxic and produces long term effects on hematological parameters and liver. Continuous exposure to high concentrations of hexavalent chromium in drinking water results in intestinal tumors in mice but not rats. However, evidence of the carcinogenic potential of chromium has been demonstrated in rats but not consistently in mice. Cr (III) organic complexes (chromium picolinate) did not show evident adverse effects after repeated oral exposure. Both in vitro and in vivo data show that trivalent chromium is not genotoxic whilst hexavalent chromium is genotoxic. Chromium has been shown to affect sperm, estrous cycle and fetal development. Human toxicity data reveals mixed results but there is some evidence that hexavalent chromium can increase the risk of cancer. Data on Nickel show that nickel soluble compounds (nickel sulphate, nickel chloride or nickel nitrate) have acute and long term toxicity and produce oxidative stress and long term effects on liver. Less soluble compounds (nickel sulfides or nickel oxides) are less toxic. Nickel shows genotoxic effects both in vitro and in vivo. Only a limited number of studies on carcinogenic effects after oral exposure to nickel compounds are available. These studies showed no neoplastic effects in rats after oral administration. Nickel has been shown to affect sperm, live litter size and post-implantation loss. Teratogenic effects are reported on Amphibian embryos. Nickel can affect neurodifferentiation, the T-cell system and suppress the activity of natural killer cells. Human data reveals that nickel is excreted in the urine following oral exposure and that this increases with increasing age. There is some evidence that nickel might promote oral cancer etiology but no clear evidence that nickel can increase the risk of respiratory cancer.

“…En estudios como el de Arruda, et al (45), se menciona la sustitución metabólica del calcio por contaminantes como el cadmio y el plomo en niños de escasos recursos como una de las hipótesis para explicar los picos de concentración de metales pesados, cercanos a los límites superiores de los promedios mundiales, encontrados en niños menores de 15 años. En Colombia, Suárez-Ortegón, et al, reportaron una asociación negativa entre los niveles altos de plomo en la sangre de mujeres en tercer trimestre de embarazo y la ingestión de cinc, calcio y vitamina B 12 , así como una asociación positiva en este mismo período de embarazo y el consumo de ácido fólico (46).…”

Socioeconomic status, eating patterns, and heavy metals exposure in women of childbearing age in Cali, Colombia

Introducción. La contaminación del agua y de los alimentos constituye un riesgo creciente para la salud a nivel mundial. Dicho riesgo varía según las concentraciones y las dosis de los contaminantes y el tiempo de exposición, especialmente por los posibles efectos a largo plazo debidos a la exposición crónica a bajas concentraciones de metales pesados como el plomo, el cadmio y el mercurio.Objetivo. Explorar la relación entre la condición socioeconómica, los patrones de alimentación y la exposición a metales pesados en una población de mujeres de Cali.Materiales y métodos. Participaron 233 mujeres en edad fértil, no embarazadas, residentes en el distrito de Aguablanca, Cali, Colombia. Se recolectó información sociodemográfica, así como sobre las condiciones de la vivienda, la exposición a metales pesados, la frecuencia de consumo de alimentos y las mediciones antropométricas. Para determinar las concentraciones de plomo, cadmio y mercurio, se tomaron muestras de lechuga, repollo y peces (tilapia y ‘manteco’). Se hicieron análisis descriptivos y de correspondencias múltiples para establecer los patrones de consumo.Resultados. El pescado se incluía en las tres comidas del día, especialmente en el almuerzo; se encontró cadmio por debajo de los niveles permitidos en tres muestras de ‘manteco’. El 11,1 % de quienes consumían pescado una vez o más por semana lo había comprado en un expendio en el cual las muestras fueron positivas para cadmio. Mediante el análisis de correspondencias múltiples, se determinó la presencia de una relación entre el ser de raza negra y el consumo de ‘manteco’ y tilapia una vez o más por semana.Conclusiones. La población de estudio tuvo acceso a alimentos contaminados con metales pesados. Esto, sumado a las características metabólicas de las mujeres y a sus condiciones socioeconómicas, incrementó su exposición y vulnerabilidad frente a los efectos de la contaminación.
