“…Fertilizers and their agricultural sludge, tobacco, municipal waste water and sewage discharges are other important sources of cadmium 15 , besides vegetables, fish, mollusks and crustaceans 3 . According to the World Health Organization, the maximum daily intake of cadmium should be 1 mg/kg of body weight 1 .…”

Objective: This study aims to evaluate the effect of the pH of drinking water in the oral changes caused by cadmium poisoning. Material and method: Ninety male Wister rats were divided into the following six groups: A - 15 rats were given cadmium chloride solution (400 mg/L) in drinking water with a neutral pH (pH 7.0); B - 15 rats received cadmium chloride solution (400 mg/L) in drinking water with an acidic pH (pH 5.0); C - 15 rats were treated with a cadmium chloride solution (400 mg/L) in drinking water with a basic pH (pH 8.0); D - 15 rats received drinking water with an acidic pH (pH 5.0); E - 15 rats were given drinking water with a basic pH (pH 8.0); F - 15 rats received water with a neutral pH (pH 7.0). All animals were sacrificed six months after the beginning of the experiment. A biopsy of the buccal mucosa, tongue and salivary gland of each animal was taken for microscopic analysis. Result: No changes were observed in the buccal mucosa, tongue mucosa or salivary glands in any of the groups. Conclusion: Drinking water that contains a high concentration of cadmium with differing pH levels demonstrated no damage to the oral mucosa and salivary glands of male Wistar rats.

“…Furthermore, metal pollution may globally have a severe negative impact on human health (Castro-González and Méndez-Armenta, 2008), with South Africa being no exception (Strydom et al, 2006). In fish, lesions caused by low concentrations of trace metals could lead to functional alterations and interference with fundamental processes such as osmoregulation, gas exchange and metabolism (Pandey et al, 2008), and subsequently also affect community structure (Bervoets et al, 2005).…”

This is the first paper reporting on results obtained in a metal bioaccumulation study in the Vaal River system. It discusses concentrations of four non-essential elements (strontium, aluminium, lead and nickel) in water, sediment and various fish tissues. A second paper will report on concentration levels of the remaining five essential trace metals (chrome, copper, iron, manganese and zinc) studied. While heavy metals did accumulate in C. gariepinus tissues, no clear trends emerged with regard to differences between localities (Vaal Dam and Vaal River Barrage) or surveys. The highest non-essential element metal concentrations were generally recorded in gill (filaments and arches), followed by muscle, liver and lastly skin. This general trend appears to be in agreement with trends observed by other workers and reported in the literature. Variability in tissue metal concentrations in C. gariepinus within locality and seasons observed in this study is also reflected in results from available literature. This accentuates the importance of factors that influence the concentrations and bioavailability of trace metals.

“…Fish, meat and meat products have been indicated as vehicles of inorganic contaminants such as Cd and Pb, with significantly different concentrations as a function of the species of fish 8,9 . In january 2011, the regular, blend and renal diets all included fish with shrimp sauce on the dinner menu of one of the days analyzed, showing higher values for Pb on this occasion as compared to the soft diet (p < 0.05).…”

“…Nevertheless, despite some controversy, studies from various parts of the world have reported the presence of Cd and/or Pb in foods such as cereals, meat and animal viscera and in teas, in amounts that could be toxic to man [7][8][9][10] . Many of these foods are considered appropriate and integrate hospital diets, such as bread, fish and teas.…”

NIVELES DE CADMIO Y PLOMO CONSUMIDOS POR PACIENTES QUE RECIBEN DIETAS HOSPITALARIAS ORALES ResumenIntroducción: Los niveles de cadmio (Cd) y plomo (Pb) en los alimentos deben ser controlados en función del riesgo para la salud.Objetivo: Evaluar los niveles de Cd y Pb en dietas hospitalarias orales y complemento alimentario oral (OFC) y sus ingestiones por pacientes, con estimativa del riesgo de exposición.Métodos: Los niveles de Cd y Pb se determinaron mediante ICP-OES en muestras de dietas regular, blanda, fluida, renal y OFC, recogidas 6 días non-consecutivos. Fueron analizados 14,3% de las dietas y OFC servidos.Resultados y Discusión: 163 pacientes participaron, con pesos y edades medias de 62,7 kg y 56,5 años, respectivamente, en su mayoría varones (59,5%). La media de Cd consumida fue mayor entre hombres alimentados con dietas regular y fluida y similar entre los sexos para la blanda. El consumo de Cd (máx. 21,2 µg/día) estaba por debajo de la ingesta provisional mensual tolerable (IPMT). El contenido medio de Pb ingerido fue similar entre sexos (máx. 199,49 µg/día). La dieta blanda mostró mayor contenido de Pb en septiembre/2010, mientras que las otras no variaron según la temporada. En septiembre/2010 y enero/2011, las dietas regular y blanda asociadas al OFC aportaron 207,50 y 210,50 µg/día de Pb, respectivamente.Conclusiones: La combinación de la dieta con OFC aumentó el riesgo de ingestión excesiva de Pb. La vulnerabilidad de los pacientes a una exposición excesiva podría ser mayor en función del agua y medicamentos. La ingestión de Cd calculada cumple el IPMT, pero el nivel de Pb y su ingestión representan riesgo para los pacientes. (Nutr Hosp. 2014;29:196-203 Conclusions: The combination of the diet with the OFC increased the risk of an excessive ingestion of Pb, and the vulnerability of the patients to an excessive exposition to Pb could be greater due to water and medications. It was concluded that whereas the calculated ingestion of Cd conformed to the PTMI, the Pb level and ingestion represented a risk to the health of the patients.
