Bisphenol A (BPA), it seems, is the substance that causes the biggest problems, according to scientists, and is mainly detected in milk and canned foods.
According to a research published in the Guardian, a cocktail of chemical pollutants associated with decrease in sperm quality.
Chemical substances such as bisphenols (a compound chemical also known as ΒΡΑ) and dioxins are thought to interfere with hormones and impair sperm quality. In fact, research has shown that combinations of these compounds exist at “impressive” levels, up to 100 times higher of what is considered safe!
Bisphenol A (BPA), it seems, is the substance that causes the biggest problems, according to scientists, and is mainly detected in milk and canned foods.
The research, then, shows that the number and concentration of sperm had a worrying decrease, mainly, in participants from western countries, with the number of sperm “to have halved in the last 40 years». Hormone-disrupting chemicals are a key suspect, and the study sheds new light on the potential for chemical cocktails to cause harm.
According to researchers, toxic chemicals threaten humanity. The study team, led by the professor Andreas Kortenkampin the Brunel University of London, stressed that “were surprised by the size of the risk index and the degree of risk from chemical cocktails». The team was also surprised by the fact that BPA was the most worrying chemical, as previous work had focused on phthalateswhich are used in plastic to increase their flexibility.
The researcher added that the research will allow better epidemiological studies to be done in humans, to assess the effects. «I believe that, with the data we have through our research, there is no reason to delay any further action».
The research, published in Environment International magazineevaluated measurements of nine chemicals, including bisphenol A, phthalates and paracetamol, in urine samples from almost 100 Danish men, aged 18 to 30 years. He also used data and data, mainly from European Food Standards Agency.
These data were compared with acceptable levels of exposure, which also emerged from the scientific literature. This gave a measure of the potential effects of each chemical, which were then added up to give an overall risk measure for the chemical cocktail to each of the men.
THE Professor Richard Sharpein the University of Edinburghsaid about the study: ““Unlike the authors of the new study and many in the scientific community, I am not convinced that exposure to environmental chemicals plays a significant role in reducing sperm count.” He explained that “There is no direct evidence and most of the chemicals evaluated in the study cause damage to human testicular development, although there is good evidence for paracetamol.».
He said he was convinced that the drop in sperm count must have an environmental cause. For the teacher, a high-fat, processed diet is as harmful in itself as the main source of chemicals, making it difficult to discern what is wrong. Nevertheless, the professor typically mentioned that certain chemical cocktails can negatively affect the number of sperm in men.
