Pesticide Malathion linked to chronic kidney disease

by Sean Martu

In my view, exposure to all of these chemical pesticides will eventually be linked to human maladies. Malathion is an organophosphate insecticide that acts as an acetylcholinesterase inhibitor, that is known as maldison in New Zealand and Australia, and as mercaptothion in South Africa.

Coincidently, in 2018 a Lawsuit Seeks to Force EPA to Curb Risks From Dangerous Pesticide Malathion, stating-

OAKLAND, Calif.— Conservation and public health groups sued the Trump administration and Environmental Protection Agency chief Scott Pruitt today for failing to protect endangered wildlife and the environment from the dangerous pesticide malathion.

Today’s lawsuit, filed in the U.S. District Court for the Northern District of California, alleges that the EPA and the U.S. Fish and Wildlife Service have failed to complete the legally required steps to fully assess and limit the dangers of the neurotoxin.

Malathion is linked to developmental disorders in children and has been found by the World Health Organization to be “probably carcinogenic to humans.” Last year EPA scientists determined that the pesticide, manufactured by Dow Chemical, poses widespread risks to protected plants and animals.

In America, it’s readily available at your local hardware stores and it’s found in common insecticides like Spectricides malathion insect spray.

This commonly available pesticide has been associated with an increased risk of chronic kidney disease (CKD) in a recent University of Queensland study.

Researchers analyzed links between pesticide exposure and the risk of kidney dysfunction in 41,847 people, using data from the USA National Health and Nutrition Examination Survey (NHANES).

School of Public Health Associate Professor, Nicholas Osborne said the study found people exposed to higher amounts of the insecticide Malathion, known as Maldison in Australia, had a 25 percent higher risk of kidney dysfunction.

“Nearly one in 10 people in high-income countries show signs of CKD, which is permanent kidney damage and loss of renal function,” Dr. Osborne said.

According to Beyond Pesticides article “Common Insecticide Malathion Linked to Chronic Kidney Disease” –

Researchers began with data drawn from the United States’ National Health and Nutrition Examination Survey (NHANES), an ongoing study that assesses Americans’ health and nutritional status through interviews, physicals, and other health tests. Urine samples taken from individuals enrolled in NHANES 2001-2004 and 2007-2010 (tests within years between these dates did not analyze specific pesticides) were reviewed for the presence of pesticides, and compared against data collected on kidney function. In addition to malathion, 2,4-D, chlorpyrifos, and 3-PBA, the major metabolite for most synthetic pyrethroid insecticides, were analyzed for their link to CKD. Scientists adjusted their statistical analysis to incorporate a range of confounders, and conducted a more sensitive analysis that excluded individuals with hypertension and a history of diabetes.

The data reveal malathion to be significantly associated with increased risk of low kidney functioning and CKD. Risk was not significantly increased by exposure to the other pesticides studied. However, malathion retained a significant association even under the sensitivity analysis adjusting for known CKD factors. “The findings suggest we should limit our exposure to pesticides, even in very small doses, as chronic exposure may lead to negative health outcomes,” Dr. Osborne said.

Dr. Osborne said,” CKD with no known cause was rising in low-to-middle income countries such as India, Sri Lanka, and Mesoamerica. Initially, it was suspected the condition was associated with agricultural workplaces through exposure to heat stress, dehydration, pesticide spraying, heavy metals, and agrochemicals”. Dr. Osborne continued. “However, environmental contamination, pesticide residues and herbal medicines potentially containing heavy metals may also be contributing to CKD.”

In 2018, the federal government’s top fisheries experts issued a report saying that the pesticide chlorpyrifos and two others — diazinon and malathion — were washing into streams and rivers and harming wildlife, such as endangered species of salmon.
