Pfizer chemical spill in Michigan causes local authorities to issue no-contact advisory of Kalamazoo River



Pfizer has admitted to a chemical spill into the Kalamazoo River, which prompted local authorities to issue a no-contact advisory for the river in Kalamazoo, Michigan. Government health agencies have declared the chemical involved in the spill to be a possible carcinogen and potentially deadly in high doses. However, Pfizer has said that it does "not anticipate any health risks."

Pfizer notified the Kalamazoo Department of Public Services about the chemical spill around 4:30 p.m. on March 12. The pharmaceutical giant revealed that it had leaked an estimated 1,057 gallons of methylene chloride within the process area of the company's manufacturing plant in Kalamazoo.

The city of Kalamazoo said in a statement, "An unknown amount of the colorless liquid was discharged into a dedicated sanitary sewer serving Pfizer, which then flows to the Kalamazoo Water Reclamation Plant (KWRP) for treatment."

The city noted that the Kalamazoo Water Reclamation Plant can only treat up to 291 gallons of methylene chloride per day.

Local officials issued a no-contact advisory for the Kalamazoo River.

"At this time, the Kalamazoo County Health & Community Services Department, in cooperation with the City of Kalamazoo Department of Public Services, are advising all persons to avoid contact with the Kalamazoo River from Paterson Street Bridge in the city of Kalamazoo to the D Ave Bridge in Cooper Township," said the statement from county and city officials.

Jim Rutherford, Kalamazoo County health officer, said, "This advisory will remain in effect until further investigation, and sampling indicates that there is no risk to public health."

Pfizer asserted, "Given the amount of the discharge and controls in place, we do not anticipate any health risks."

"Pfizer will continue to work with the City of Kalamazoo and is firmly committed to assessing and minimizing any potential impacts on human health, the environment, and the communities in which it operates," the pharmaceutical company stated.

According to the Centers for Disease Control and Prevention, "Methylene chloride (CH2Cl2) is a colorless liquid that can harm the eyes, skin, liver, and heart. Exposure can cause drowsiness, dizziness, numbness and tingling limbs, and nausea. It may cause cancer. Severe exposure can cause loss of consciousness and death."

Besides being used in pharmaceutical manufacturing, methylene chloride is found in paint strippers, metal cleaners, adhesives, and lubricants.

According to the Occupational Safety and Health Administration, 17 American workers died while using methylene chloride paint-stripping products to refinish bathtubs between 2000 and 2015.

OSHA considers methylene chloride to be a potential occupational carcinogen.

The Environmental Protection Agency classifies methylene chloride as a "toxic waste when a discarded commercial chemical product or manufacturing chemical intermediate or an off-specification commercial chemical product or manufacturing chemical intermediate."

The Kalamazoo location is Pfizer's largest pharmaceutical manufacturing plant, according to the company.

The 1,300-acre facility manufactures active pharmaceutical ingredients, drug products, and medical devices. Each year, the Kalamazoo facility produces 1,200 metric tons of products.

Microplastics have been recorded in freshly fallen snow on Antarctica



Microplastics have been found in freshly fallen snow in Antarctica for the first time in recorded history.

The Guardian reported that this unnatural development poses a distinct threat to the health of Antarctica’s unique ecosystems and could accelerate the melting of the continents ice and snow.

Microplastics — which are individually smaller than a grain of rice —have previously been found in Antarctic Sea ice and surface water but this is the first time in recorded history that they have been found in fresh snowfall.

Research conducted by Alex Aves, a PhD student from the University of Canterbury, and his supervisor Dr. Laura Revell, chronicled the recent phenomenon.

For his research, Aves collected snow samples from the Ross Ice Shelf in late 2019 to determine whether microplastics had been transferred rom the atmosphere into the snow. Until Aves conducted this research, there had been very little research about the presence of microplastics on the continent of Antarctica.

Dr. Revell said, “We were optimistic that she wouldn’t find any microplastics in such a pristine and remote location.”

Dr. Revell indicated that she had instructed Aves to also collect samples from various established roadways on the continent, where microplastics have previously been recorded, so that “she’d have at least some microplastics to study.”

As it turns out, Dr. Revell’s precautions were unnecessary as plastic particles were found in every one of the 19 samples Aves gathered from the Ross Ice Shelf.

Aves said, “It’s incredibly sad but finding microplastics in fresh Antarctic snow highlights the extent of plastic pollution into even the most remote regions of the world.”

Aves found an average of 29 microplastic particles per liter of melted snow, which is reportedly higher than recorded marine concentrations that were gathered from the surrounding Ross Sea and Antarctic Sea ice.

There were 13 different types of microplastic found in the samples Aves gathered. The most common type found was PET which is commonly used in the manufacture of plastic drink bottles and clothing.

Atmospheric modeling suggested that these microplastics may have traveled thousands of kilometers through the air as it is unlikely that the humans currently residing in Antarctica have caused enough plastic pollution to generate the requisite concentration of microplastics in the atmosphere.

Microplastics and plastic pollution have become remarkably far spread as they reportedly been found at the summit of Mount Everest and in the depths of the planet’s oceans.

People inadvertently eat and breathe microplastics according to some studies and other studies found that microplastic particles cause damage to human cells. One study from 2021 found that airborne microplastics are “spiraling around the globe.”
