Scientists are studying the effects of PCB levels in the blood for the last ten years. In actual Polychlorinated biphenyls are environmental pollutants that are banned in many countries. Though many countries have put a ban on PCBs they can still be traced in the bodies of human beings. PCB has long half-life and thus they degrade at a slow rate, their elements are stored inside the fatty tissues of human beings which can easily be traced in the blood.
During the study, scientists have taken more than 950 individuals from Uppsala. All the individuals are near about 70 years old. Scientists had recorded the blood samples of people first when they were 70 years old and the second time after five years of long gap. According to the study, scientists have found that individuals who had died during the research had a high level of chlorine inside their body. Such people are also prone to various cardiovascular ailments.
Studies conducted previously showcased a direct link between atherosclerosis and high level of Polychlorinated biphenyls. Thus, most of the researchers are advocating that the PCB levels should be regulated in food items.
During an interview, Monica Lind stated that humans get most of the PCB in their bloodstream through food items. She also said that since PCBs are lipid loving thus they can easily be found in meat, fish as well as in dairy products. Dr. Monica Lind also stated that high quantities of PCBs are recorded in wild salmon and Baltic herring which are fished from highly polluted lakes and water bodies.
Along with Lars Lind and several environmental chemists from Orebro University, Monica Lind had conducted in-depth research on PBC. The researchers have tried to find the direct relationship between the PBC level inside the human body and death rate.
