Inorganic contaminants workshop, Denver, Colorado. Effects of arthrobacter sp., acidovorax delafieldii, and bacillus megaterium colonisation on copper solvency in a laboratory setting. NSF International (2015d). Also, neonates and infants appear to be more sensitive due to their enhanced intestinal absorption and immature hepatobiliary system (Collins and Klevay, 2011). (2012). NSF International, Ann Arbor, Michigan. Bicinchoninate Method. 6th edition. Dietary reference intakes tables. Risk Assess. Water pH in some communities is so low, that even with treatment, it would be difficult to dose enough chemical to meet both pH and copper guidelines. Gastroenterology, 137(5 Suppl): S13–S17. Leaking pipes present an additional health risk as they could lead to mould growth (Scardina et al., 2008), affecting indoor air quality (Health Canada, 2016). Overall, chronic ingestion of up to 31.48 µmol Cu/L by infants (in their formula [F], foods and drinking water), from three months to one year old, did not result in any acute or chronic effects. Copper and Alzheimer's disease. Also, as with the short-term studies, the symptom risks were positively associated with copper concentration and the female sex, and negatively related to time. Nevertheless, the significance of NOM to cuprosolvency relative to competing ligands has not been conclusively determined (Schock et al., 1995; Ferguson et al., 1996). (1997). Health Perspect., 109(9): 949–952. Bus bar. Toxicology, 283(2–3): 65–87. Integrated Risk Information System (IRIS). Senesse, P., Meance, S., Cottet, V., Faivre, J. and Boutron-Ruault, M. (2004). National Plumbing Code. Neurology, 59(8): 1153–1161. Products that use adsorption technology can lose removal capacity through usage and time and need to be maintained and/or replaced. Kessler, H., Pajonk, F.G., Meisser, P., Schneider-Axmann, T., Hoffmann, K.H., Supprian, T., Herrmann, W., Obeid, R., Multhaup, G., Falkai, P. and Bayer, T.A. Technol., 40(9): 17–24. The U.S. National Academy of Medicine (formerly called the Institute of Medicine)  has established recommended daily allowances of 900 µg/day for adults and 340–890 µg/day for children, as well as tolerable upper intake levels of 10,000 µg/day for adults, and between 1,000 and 8,000 µg/day for children. (1990). This mirrored the results from the utility survey that indicated few problems with copper (and lead) release when chloramines were used for secondary disinfection (Sandvig et al., 2012). Sample preparation to ensure that both the particulate and dissolved fractions of copper are capable of being detected is best practice, especially for diagnostic purposes. Copper release may result in blue water, which can stain bathroom fixtures and hair and may be caused by the presence of particulate copper. Morphological and biochemical assessment of the liver response to excess dietary copper in fischer 344 rats. Araya, M., Olivares, M., Pizarro, F., Mendez, M.A., Gonzalez, M. and Uauy, R. (2005b). (2012). Med. After an overnight fast, subjects (179/group) were randomly given 0, 0.4, 0.8, 1.2, or 1.6 mg Cu(II) (as copper sulphate salt) in a bolus of 200 mL distilled-deionized water (equivalent to 0, 2, 4, 6, or 8 mg Cu(II)/L) once per week over five consecutive weeks. Am. Neurol., 91(3): 546–558. Dissolved oxygen and/or chlorine residual/oxidants are also important considerations for copper. Despite that there were some reports of teratogenicity and feto-lethality following ingestion of copper at high doses (above 80–390 mg/kg bw), these outcomes were attributed to dam toxicity (IPCS, 1998; NRC, 2000; EFSA, 2006). ISBN 978-0-85272-856-7 (print version). Atlanta, Georgia. Fischer, W., Paradies, H.H., Wagner, D. and Hänβel, I. (1999). A number of certified residential treatment devices are available that can remove copper from drinking water to below the proposed MAC of 2 mg/L. Copper pesticides. Environ. Kim, B.E., Nevitt, T. and Thiele, D.J. The resulting product is then divided by 0.75 litres per day. Jiménez Del Rı́o, M. and Vélez-Pardo, C. (2004). Aging Neurosci., 6: 92. Jantsch, W., Kulig, K. and Rumack, B.H. A study of dose response and organ susceptibility of copper toxicity in a rat model. Res., 4(6): 252. 09-MD-2098. Environ. Health Canada does not recommend specific brands of drinking water treatment devices, but it strongly recommends that consumers use devices that have been certified by an accredited certification body as meeting the appropriate NSF/ANSI drinking water treatment unit standard(s).
