According to new findings published in the journal Science of the Total Environment, researchers from the University of Granada in Granada, Spain, have found that exposure to a chemical pollutant known as PCB-153 is positively linked to the risk of cancer in males. This agent can still be found in some fat-rich foods, particularly large, fat-rich fish.
For the study, researchers analyzed the accumulated levels of various pollutants in the body fat of 268 adults and identified those who developed cancer over a 9-year period.
Results showed that the accumulated exposure of PCB-153 was positively associated with the risk of cancer among men.
PCB-153 is part of a group of chemicals widely used in various types of industrial equipment. Because of its high resistance to degradation, the researchers suggest that fat food is the main source of exposure to the chemical pollutant. A fat-rich diet may be the cause of high PCB levels.
The researchers also hypothesize that the pollutant could interact with hormone receptors, produce free radicals, or alter DNA, thus causing cancer.
An international research project with the participation of the University of Granada has demonstrated that exposure to a chemical pollutant called PCB-153 is positively associated to the risk of cancer in males.
