A study conducted at the University of British Columbia, with endangered killer whales (orca) revealed a striking fact about the According to the research conducted by scientists, in the extinction of these giant creatures, which can reach 8 meters in length, used in the manufacture of toilet paper Some chemicals have a large share.

Examining tissue samples from killer whales that died off the coast of British Columbia in western Canada between 2006 and 2018, scientists found that 4-nonylphenol (4NPThey discovered compounds called ). Canada, this connection”toxic“According to Canadian experts, 4NP is a chemical that can affect the nervous system and cognitive functions.

The chemical that kills killer whales can also be transmitted to humans via salmon!

According to US Environmental Protection Agency data shared by British Columbia, Washington and Oregon in 2020 only 74 of them orca left. The scientists cited ship effect, water pollution and a decline in salmon numbers as reasons for the decline in killer whale numbers. The new research has also revealed a striking fact. Killer whales are doomed, among other things, to the chemicals involved in toilet paper production.

This is not the only striking thing about the event. According to scientists, 4NP reaches whales through salmon fish. In addition, salmon is one of the fish commonly consumed by humans. This is 4NP possibly passed on to humans set thinking. In the statement of Juan Jose Alava, one of the names involved in the investigation, “This research is a wake-up call.phrases were used. The statement from the University of British Columbia stated that the salmon, which is at the bottom of the food chain, carry 4NP into the sea to the killer whales. it is very likely gave up. A ban on the production of the chemical 4NP would help orcas, according to the university.
