Endocrine disruptive chemicals detected in DOLPHINS & # 039; urinate for the first time

In the study, researchers collected urine samples from dolphins in Sarasota Bay, Florida, between 2016 and 2017. Previous research uncovered evidence of phthalate metabolites in dolphin fat and skin. But, the new work shows that the problem is deeper than that

Chemical compounds found in a large number of household products, from cleaning products to cosmetics, have now been introduced into the bodies of wild marine mammals.

Scientists say they have documented the presence of phthalates in dolphin urine for the first time, indicating that they remain in the body long enough to be metabolized.

These additives include chemicals known as endocrine disruptors, which have been linked to hormonal and reproductive problems in humans.

Among the known side effects, phthalates have been linked to low sperm count and abnormal development of the reproductive organs.

At this stage, however, it is not clear how the dolphins will affect.

In the study, researchers collected urine samples from dolphins in Sarasota Bay, Florida between 2016 and 2017.

Previous research uncovered evidence of phthalate metabolites in dolphin fat and skin.

But, the new work shows that the problem is deeper than that.

Urine samples from 17 wild dolphins in the region revealed phthalate metabolites in 17 percent of the dolphins. The researchers rested for nine specific phthalates.

"We focus on urine in dolphins because, in previous studies in humans, that has been the most reliable matrix to indicate short-term exposure," said Leslie Hart, professor of public health at the College of Charleston.

While humans may be exposed to phthalates through cleaning products, cosmetics and personal care items, the source of the levels seen in dolphins is still somewhat mysterious.

But researchers say plastic waste could be the culprit, since high concentrations of a specific compound commonly found in urine plastics were found.

"These chemicals can enter marine waters due to urban runoff and agricultural or industrial emissions, but we also know that there is a lot of plastic pollution in the environment," Hart said.

Phthalates are commonly added to products for durability and lubrication. The tests reveal products of initial breakdown by the liver.

WHAT ARE THESE CHEMICALS?

The so-called endocrine disrupting chemicals (EDCs) are found in thousands of everyday products, ranging from plastic containers and metal foods to detergents, flame retardants, toys and cosmetics.

This term covers a quantity of chemicals.

One is called PBDE, which is commonly found in flame retardants.

Bisphenol A in polycarbonate plastic is used for reusable bottles and food containers. Phthalates are used for disposable water bottles.

WHAT DO THEY DO?

The invisible chemist causes neurological and behavioral disorders such as autism and ADHD.

They also affect the IQ.

And they manipulate the hormones in a way that can cause cancer, diabetes, male infertility and endometriosis.

"We are looking for metabolites," Hart said. "These are indicators that the dolphins have been exposed somewhere in their environment and that the body has begun to process them."

There are approximately 160 dolphins living in Sarasota Bay.

And, it is said that these animals are good indicators of what is happening in the coastal area.

According to Gina Ylitalo, an analytical chemistry from NOAA's Northwest Fisheries Science Center that was not involved in the study, the discovery of these chemicals in dolphins means that other marine life in the area is likely to be exposed as well.
