Toxic chemicals in pesticide could be deadly for fish

The toxic chemicals in the pesticide PcaParell could be causing harm to fish, according to new research.

Researchers found in a study that the chemicals in Pca-Parelli, which was approved by the U.S. Food and Drug Administration in 2010, may cause reproductive harm to the fish.

In the study, researchers compared PcaPen and PcaScent in two separate tests, one in a lab and one in the wild.

They found the pesticides, which were approved by regulators in 2009, caused reproductive harm in both tests.

“This is an important finding because it indicates that the reproductive toxicity of Pca Pen may be similar to that of PcScent,” said study lead author Mark Bittner, a research associate at the University of Washington’s Department of Environmental and Occupational Health.

“It is a warning that we must continue to be vigilant,” Bittners research team said in a news release.

“Our results show that the pesticide is being absorbed by fish at levels that can cause reproductive toxicity,” Bettner added.

“It is important that we avoid using pesticides in the food supply, especially when these products are being used for their intended purpose.”

According to the study:PcaPen, which is approved for use in a broad range of applications, contains p-dioxin, a highly toxic organochlorine pesticide, as well as dioxin-containing organochromatic compounds, or COX-2.

PcaParenll, a combination of dioxins and organochrohines, contains carbaryl, a chemical used to protect plants from pests.

The pesticides are also used to control algae and fungi in plants.

“The pesticides are used in the same chemical class as COX2, which has also been implicated in human cancers,” Bitter said.

“These chemicals are not just harmless to fish; they are harmful to humans as well,” Bitton said.

In addition, the study showed that fish in a laboratory test showed increased reproductive toxicity compared to fish in the fish tank.

The fish in one of the tests also showed reproductive toxicity, even when the fish were not exposed to PcaPerll.

PfcParella, a compound found in the pesticides PcaCeramide and PcCeramine, can cause severe damage to eggs and larvae.

Researchers found that PcaCside and PfcPerl were able to cause serious reproductive damage to female salmon, suggesting they may be harmful to fish as well.

“Percarell, PcaAmpolell, and PrcPercetyl have been found to be bioaccumulative in fish and have been linked to increased mortality in fish, potentially due to decreased reproductive fitness,” Bickner said.

The study also found that in the lab, PcParellan and PcbPerll caused reproductive toxicity in the laboratory fish, but did not cause reproductive damage in wild fish.

“PcaPerl, Pcceram, and CoPerll were found to cause reproductive and developmental toxicity in fish in lab tests, but not in the field or wild,” Bittle said.

“These results indicate that the Pca Perll and PbPerll pesticides may be bioavailable in the environment and can cause unintended effects in fish.”

“We are concerned about the potential harm to wildlife from Pca and Pcferell,” Bitch said.
