Zacatecas, Zac. Constant exposure to chemical compounds in the form of nanoparticles, contained in new cosmetics, foods, as well as products related to health and personal care, is linked to fertility problems in women, so it is important that the government regulate their use. importation, since its commercialization is carried out on many occasions without true and complete information on the labeling.
In an interview, the Mexican scientist Ramsés Santacruz Márquez, a graduate of the Autonomous University of Zacatecas and Cinvestav, said the above. He is currently doing studies on the harmful effects of nanoparticles on women’s fertility and other chemical compounds such as phthalates and bisphenol (Bpa), at the Department of Biocomparative Sciences at the University of Illinois.
Santacruz Márquez carried out his first studies on the toxicology of Bpa “evaluating how exposure to this compound can affect reproductive functions, particularly on female germ cells, the ovum or oocyte,” in laboratory mice.
She then developed a project to see how certain nanoparticles can affect the reproductive functions of women, in particular the antral follicle (a set of cells that are in the ovary), which contribute to the synthesis of hormones and the development of germ cells.
These are novel studies, because although nanoparticles have been used in certain products in the industrial field for years, there are currently others for daily use, particularly to make cosmetics such as sunscreens, “and even food, and the most worrying thing is that on their label of manufacture, it is not necessarily specified what they contain.
“For the same reason, its use is relatively new. There are not many toxicity studies. In the end, these studies are very important, as they help to understand and regulate their use.” It is necessary for governments to focus on regulating their commercialization and application, “making their regulation a little stricter, so that their compounds are identified on the labeling.”
Santacruz Márquez says he is satisfied with his postdoctoral work and the conditions in which he develops it at the Urban-Champaign unit of the University of Illinois, Chicago, although he admits that “if at any time I can return to Mexico, if I find a good opportunity to work and continue to do more research, I would.”
On which he works, he points out that it is relevant and has a social impact “because infertility problems have been growing, parallel to the increase in the consumption of different products, which, it has been seen, are associated.”
He trusts that one day in Mexico this type of research “will help regulate the use of different compounds that can affect the population.
“It has been seen that phthalates are associated with diseases or alterations at the reproductive level. I would recommend checking cosmetics to see what ingredients they contain and begin to see and understand. “The government would have the task of reducing or limiting, but that the use of phthalates in these cosmetic products is done in concentrations or ranges that are known with scientific certainty, that they will not have adverse effects.”
He even revealed that these substances not only affect the reproductive system, since “there are effects on different functions in the immune, cardiovascular and respiratory systems.” The most serious thing, he pointed out, is that these products “can also affect multi- and trans-generational people. That is, perhaps the mother was exposed and the harmful effects also appear in the daughter or even the granddaughter, as has been verified in the laboratories where he works, with studies carried out on animals.
