Schell and DeCaprio began their work with Gallo and Jacobs in this there latest article of the young Mohawk adult population of the Akwesane. As we found out in Schell et all 2009, “current toxicant body burden is still a primary concern wihin the Akwesasne Mohawk Nation since other studies conducted within the community have shown relationships between these POPs and endocrine disruption.” Breastmilk was shown to increase the toxicant level in future adults, and persistant organic pollutants may increase the risk of acquiring an autoimmune disease and thyroid disease. This 2011 study contains more data on more types of POPs than the 2008 study. In this study the Mohawk were asked about their consumption of wild game such as Rabbits or Deer, and their Body Mass Index was studied. Men were said to consume significantly more calories protein fat and cholestoral then women did. They also consumed more alchohol. Interestingly, they expanded their data to cover different births in a family. Example: they show the difference in toxicant levels by first born, second born, third born and finally fourth born when applicable. Interestingly, the data shows a drop in toxicants as more children are born. They then correlated the new data with CDC data and printed a graph. Gallo et al 2011, make the bold claim that because of these studies, they now have the ability to test the levels of a multitude of different congeners. The result of the six-year study was rather famous. They were able to lessen potential obfuscations of relevant data. They proved that PCB levels in these young Apache were significantly higher than in the general population. They show past and present levels, giving a timeline to these toxicants. They show evidence that PCB exposure is ongoing in Apache adults as they grow and reflect recent exposure. The breastfeeding data is the best evidence ever collected. To the best of our knowledge, no other study has found differences between levels among breastfed and non-breastfed individuals of this magnitude and duration. Food intake was studied and given further value to the theory that toxicants are carried by certain food intake. Additional research in this area was requested therefore a new study into this may be forthcoming and future researchers must be aware of this.
