Letter: Hair-metal binding.
reduce the MMT partial pressure to an even smaller value. It is obvious from the above that the po£-sibility of hazardous exposure of customers has to be much lower even than would be the case for TEL. When this is considered in light of the studies of Kehoe et al. in the 1960s on lead alkyls and service station attendants (who would have more exposure than self-service customers) in which it i...
متن کاملHair–Metal Binding*
Extensive ambient extraction of several metals from human hair compromises some assumptions concerning the binding of metals to hair and the biochemical process of metal incorporation into hair. Hair metal concentrations can reveal metal intoxications and metal deficiencies.The scalp hair selected for investigation included specimens of different colors from both sexes for various donor ages an...
متن کاملMetal-binding proteins as metal pollution indicators.
The fact that metal-binding proteins are a consequence of elevated metal concentration in organisms is well known. What has been overlooked is that the presence of these proteins provides a unique opportunity to reformulate the criteria of metal pollution. The detoxification effect of metal-binding proteins in animals from polluted areas has been cited, but there have been only very few studies...
متن کاملMenkes disease--an autopsy case with metal analysis of hair.
We report the first case of Menkes' disease in Korea, occurring in a 1 1/2 year old boy with characteristic clinical, arteriographic and pathologic features. Postmortem examination revealed widespread neuronal destruction and abnormally tortuous and elongated large arteries including cerebral, visceral and limb vessels. Microscopically, many of the hairs formed were twisted (pili torti), of var...
متن کاملMetal-binding mechanisms in metallothioneins.
Metallothionein are small, cysteine-rich, metal-binding proteins that are found ubiquitously in nature. Most metallothioneins bind multiple metals in two well-defined metal-thiolate clusters. This perspective discusses the use of optical spectroscopy to study the metalation of metallothioneins and the emergence of electrospray ionization mass spectrometry as a means of studying the mechanism of...
