Hazardous waste can cause bisexual syndrome in polar bears

The toxic Arctic waste is a major threat to polar white bears, which can lead to "hermaphrodite" in polar bears and brain damage, according to a recent study. out.

"Bisexual" here is not the same as homosexuality in humans, this is an animal syndrome that appears in both genital types of males and females.

The "bisexual" case of growing polar bears may be the result of endocrine disruption by toxic waste.

Analysis of the effects of persistent organic waste (POPs) on Arctic animals, some researchers at Milano Bicocca University in Italy have found that polar bears face those The risk of health is greater than that of seals, and baby bears are the most at risk.

Widely used in industry after World War II, POPs are toxic chemicals that negatively affect human health, animals and the environment. It can be mediated by wind and water, accumulated in the environment and animals through the food chain.

Researchers in Norway observed in 1996 two "hermaphrodite" cases in polar bears. These animals have both a normal vaginal opening and a penis in it. However, both bears do not have Y chromosomes, which are used to identify them as males.

Scientists believe that "hermaphrodite" cases in growing polar bears may be the result of endocrine disorders caused by toxic waste.
