Bisphenol A, a chemical commonly found in plastic products such as baby bottles, is being replaced by materials such as bisphenol S due to its health risks. A mouse experiment published in the Journal of Contemporary Biology on the 13th shows that these alternative materials are the same. Like bisphenol A, it can still cause fertility problems.
Many plastic products on the market are beginning to be labeled with 'bisphenol A-free', claiming safe and safe use. Most of these products use alternative materials such as bisphenol S, a chemical similar to bisphenol A.
Researchers at Washington State University and the University of California, San Francisco found that in mice exposed to bisphenol S, germ cells in the testes and ovaries produce DNA (deoxyribonucleic acid) recombination problems in the production of sperm and eggs, leading to live Reduced sperm count and increased number of abnormal eggs. Alternatives such as bisphenol F, bisphenol AF and diphenyl sulfone may also cause similar consequences.
Previous studies in the United States have shown that bisphenol S may be as toxic as bisphenol A. Animal experiments have shown that it affects brain development and leads to hyperactivity, so special populations such as pregnant women should limit exposure to bisphenol-containing articles.
The author of the paper, Patricia Hunt, a professor at Washington State University, said that there is growing evidence that although these commonly used alternatives to bisphenol A are more stable, they are not safe. Hunt said. Other widely used chemicals that destroy endocrine functions, such as parabens, phthalates and flame retardants, may have a negative impact on fertility and more research is needed.
