This is a very important article in the field of deriving trace elements in blood and tissue of Inuit people; the Inuit are a tribal government in Northern Canada. Its data is fairly recent which means this should be the best example of its kind although later studies based on this research could be searched for. Although it is obvious, it will be mentioned, all of the participants in the study were women. It should be noted for the record that Inuit and Eskimo are not always the same thing. It should also be noted that the use of the word Eskimo is sensitive and should be treated as a politically incorrect term, which is regarded as a pejorative that could be extremely offensive to the Inuit people and should not be used anymore as a guideline. Caucasian is a member of a northern tribe whos ancestors were from the Caucasus mountains This research was done by an unusual amount of authors because of the wide-ranging, vast array of data points. First the methodology is described, the demographic of those tested is revealed, how long the recruitment phase was, also mean age and standard deviation. Certain factors are isolated, for example because nearly (77%) of Inuit’s smoke cigarettes regularly, there were trace elements of cadmium higher than in average in the population. Contaminant data is judged against Caucasian people by using Umbilical samples from both races. Lead, Mercury, Total and Inorganic and Methylmercury was tested. Relationships between maternal and umbilical cord blood levels were tested. Evidence of Metals were tested for including Copper, Lead and Selenium, again the Caucasians were also test against several local tribes. Levels of mercury, cadmium, and lead, copper, zinc and selenium have been quantified in a nonrandom subset of women of reproductive age who voluntarily participated in an exposure assessment between 1994 and 1999. Later another study was done by as many of the same participants as could be retrieved and studied again. Overall results said, the smoking epidemic in the Inuit people has reached dangerous levels, and that the mercury they consume from their traditional diet is demonstrably higher than in Caucasian control group. This article is nearly entirely hard quantitative data and should be excellent for anyone who needs it.
