Chemical substances 'not strange' cause gender change

These toxic chemicals also disturb the hormones in the body and adversely affect our nervous system .

Sex change is a problem that scientists are still studying. It is a phenomenon in which our bodies show signs of changes, hormones, hormones in the body are disturbed, men become more feminine .

Scientists have pointed out that one of the factors that puts us at risk for sex change is due to high exposure to toxic chemicals. Let's review a few chemicals that have such a damaging effect through the following article.

1. Phthalates chemicals

Phthalate compound is a chemical, used as a substance to help plastic, softer, and increase heat resistance in products. This substance is often present in automotive interior products, plastic pipes, poor quality toys, unbranded plastics, origin .

Signs to recognize Phthalates are light products with a strong odor of plastic. Because Phthalates is a plastic softener rather than a tight bond, it is easy to fade. The higher the temperature of the product, the greater the chance that the product will fade.

In the process of using the product, the Phthalates derivatives will separate, dissolve into the air or the food is contained and then digest, "penetrate" the human body.

The harm that Phthalates brings to our bodies is disturbing hormones, making girls vulnerable to puberty Phthalates before age. Research by scientists at the University of Rochester (USA) shows that Phthalates also has resistance to male sex hormones - androgen. When exposed to Phthalates regularly, many boys will have less masculine behavior and disturbance of male sex hormones in the body.

In October 2012, the European Union (EU) issued an ultimatum to China and warned not to import some of its products - including children's toys, because of these products. meet safety standards. By European Union standards, toys will be considered unsafe if Phthalates occupy more than 0.1% of the product weight.

Along with that, experts recommend that users should watch the product labels carefully to avoid buying products that contain Phthalates. The point that consumers should pay attention to is avoiding products containing DBP (di-n-butyl phthalate) and DEP (diethyl phthalate) in beauty products; DEHP (di-2-ethylhexyl phthalate) or Bis (2-ethylhexyl) phthalate in plastic products, medical instruments; BBP (benzyl butyl phthalate) in cleaning products; DMP (dimethyl phthalate) in plant protection products .

2. Bisphenol-A chemical (BPA)

Bisphenol A (BPA) is an industrial chemical found in the manufacture of hard plastic bottles and food containers. Recent studies have raised concerns about the potential effects of BPA on fetal brain, prostate, behavioral emotional disorders, infertility in men and in particular, it has can change human sex.

There is a fact that few people know that BPA is soluble in fat, it penetrates into the human body through food and respiration because it appears in both flying dust.

Besides, according to scientists, some foods are packed in unsafe tins or poor quality plastic bags containing Bisphenol-A chemicals (BPA) 1,000 times higher than fresh food.

Harvard researchers (USA) divided 75 people into 2 groups, asking the first group to eat a box of soup with tin shells every day, lasting 5 days. The other group ate soup in a tin-free container. After 2 days off, this menu is exchanged.

Results showed that those who ate / drank food placed in tins for five consecutive days had BPA levels in their urine that increased to 1,200 percent.

Another study conducted by molecular biologist Patricia Hunt on mice showed that BPA can interfere with genetic genetics and alter human sex. Not only that, the next experiment also showed that female chromosomal damage occurred for generations and caused premature birth.

Experts recommend that foods containing BPA-containing plastic products should not be heated because the level of danger increases greatly.

The reason is that in this plastic product contains extremely toxic substances - DOP (dioctin phthalate) - a plasticizer that acts like hormones of women. This substance will have a big impact on men when the genital organ is in a complete development stage.

One of the points to keep in mind is to look at the symbol on the plastic product. If you see a triangle with 7 in it, the product is in the presence of BPA, although it does not affect immediately but needs to be limited.

3. Atrazine chemicals

Atrazine is one of the most popular and controversial herbicides that can turn male frogs into female frogs. Experimental results from experts at the University of California Berkeley (USA) indicate the effect of atrazine, which is known to be a major hormone breaker and "suspect" in the decline in the number of amphibians throughout. world.

After conducting research on 40 male frogs, Professor Tyrone Hayes and colleagues discovered that male frogs exposed to atrazine herbicide lost the ability of males and turned into females as adults.

In further study, the expert found that atrazine was able to convert male hormones into female hormones, which made the female genitals grow on the male body. This suggests: "Atrazine has caused hormonal imbalances that cause frogs to develop false sex in terms of genetic makeup".

Although scientists have not enough evidence to confirm, atrazine affects humans as much as frogs do. But many people are still concerned about the link between the use of water and Atrazine infection which will harm the body and affect human reproductive problems.
