Bisphenol A, otro cancerĂgeno dispersado por error
El bisfenol A se encuentra en gran cantidad de dispensadores de agua, contenedores de alimentos y botellas reutilizables porque hace que los plĂ¡sticos sean mĂ¡s flexibles y mĂ¡s difĂciles de romper.
Pero la sustancia quĂmica que modifica el gĂ©nero, tambiĂ©n llamada BPA, imita la hormona sexual femenina estrĂ³geno y se ha relacionado con recuentos bajos de espermatozoides e infertilidad en los hombres, asĂ como con cĂ¡ncer de mama y de prĂ³stata .
Los funcionarios de la UE han dicho ahora que el nivel actual de exposiciĂ³n recomendado al BPA a travĂ©s de alimentos y bebidas es 20.000 veces demasiado alto.
Los funcionarios tomaron esta decisiĂ³n despuĂ©s de revisar 800 nuevos estudios.
Esto incluyĂ³ uno en ratones que sugiriĂ³ que una alta exposiciĂ³n al BPA podrĂa causar que el sistema inmunolĂ³gico ataque al cuerpo por error.
Durante años ha habido preocupaciĂ³n por la fuga de BPA de los envases directamente a los alimentos y bebidas, lo que podrĂa dañar el cuerpo.
Los organismos de control de la UE dictaminaron anteriormente en 2015 que una exposiciĂ³n diaria segura, a travĂ©s de las pequeñas cantidades que se escapan de los envases de plĂ¡stico, era de 4 microgramos por kilogramo de peso corporal de una persona.
Pero los expertos de la Autoridad Europea de Seguridad Alimentaria (EFSA) del bloque han revisado esta cifra a 0,2 nanogramos por kilogramo por dĂa.
Dado que un nanogramo representa una milmillonĂ©sima parte de un gramo, esto significa que la nueva cifra segura es 20.000 veces menor que el lĂmite anterior.
Bisphenol A is found in many water dispensers, food containers, and reusable bottles because it makes plastics more flexible and harder to break.
But the gender-bending chemical, also called BPA, mimics the female sex hormone estrogen and has been linked to low sperm counts and infertility in men, as well as breast and prostate cancer.
EU officials have now said that the current recommended exposure level to BPA through food and drink is 20,000 times too high.
Officials made this decision after reviewing 800 new studies.
This included one in mice that suggested that high exposure to BPA could cause the immune system to attack the body by mistake.
For years there has been concern about BPA leaking from packaging directly into foods and drinks, which could harm the body.
EU watchdogs previously ruled in 2015 that a safe daily exposure, through small amounts leaking from plastic packaging, was 4 micrograms per kilogram of a person's body weight.
But experts at the bloc's European Food Safety Authority (EFSA) have revised this figure to 0.2 nanograms per kilogram per day.
Since a nanogram represents one billionth of a gram, this means that the new safe figure is 20,000 times smaller than the previous limit.
