“…21, 22 It has also been measured in liver and fat of three types of sea turtles in the Canary Islands, Spain. 53 A few studies detected PCB 209 in human blood and serum. 14, 15, 27, 54 Our current study found 134 participants (about 77%) contained PCB 209 in their serum (79 adults and 55 children).…”

Although polychlorinated biphenyls are no longer sold as commercial mixtures, they are still being produced through modern manufacturing processes. We have previously shown that non-Aroclor PCB11 is prevalent in indoor and outdoor air, sediment, and detected in human serum. Here we report the prevalence of non-Aroclor PCB congeners (≤0.20 weight percent in Aroclor) in human serum collected from urban and rural adolescents and their mothers. We hypothesized that additional non-Aroclors congeners are present in serum. Sera were extracted and detected for 209 PCBs using gas chromatography-tandem mass spectrometry. A list of 70 non-Aroclor PCB congeners was determined by measurement of original Aroclors. PCB 11, 14, 35 and 209 are the major dominating and most frequently detected congeners. PCB 14 and 35 have not been previously reported for environmental matrices. Adolescents have significantly lower total non-Aroclor PCBs concentration than mothers in East Chicago (p<0.001) and Columbus Junction (p=0.008). There are significant differences in non-Aroclor PCBs between East Chicago community and Columbus Junction community (p<0.001). Non-Aroclor PCBs represent an average of 10% (and up to 50%) of total PCBs measured in serum. An average of 50% (and up to 100%) of these concentrations may attribute to aryl azo and phthalocyanine paint pigments.

“…Modulation of the immune system has also been the basis for publications correlating contaminant levels with syndromes, infections or disease. For example, Orós et al (2009) examined the relationship between PCB load and causes of death in stranded turtles in the Canary Islands. Although no significant correlation was detected for septicaemia, turtles with the highest contaminant loads exhibited extreme infection.…”

“…However, data available for baseline levels of contaminants and effects on the turtle populations of the Canary Islands are scarce (Torrent et al, 2004;Monagas et al, 2008;Orós et al, 2009). Analysis of blood samples from sea turtles is a reliable non-lethal method to estimate environmental exposure to contaminants, especially persistent organic pollutants and metals (van de Merwe et al, 2009).…”
