Most people think that if pesticides are applied to their property, then it stays on their property. But that view is wrong. It has long been known that there is drift to neighboring properties when pesticides are applied, with even more drift occurring when it is windy. But what if there are schools or playgrounds nearby?

Research conducted in the Illinois found that pesticides from large-scale applications (farms, golf courses), drift hundreds and thousands of feet onto parks, playgrounds, and schoolyards. The researchers referred to the drifting of pesticides and landing away from the target area as "chemical trespass".

The researchers looked for 18 pesticides at 10 sites (school playgrounds and public parks) by sampling the sites monthly during 5 warm months (May - September). Silicone monitoring bands were used and foliage samples were taken. During the 5 months between 1 and 10 pesticides were detected at each site, with 2,4-D found at every site every month. (NOTE: 2,4-D was one of 2 pesticides in Agent Orange, and is still commonly used on lawns.)

Yes, many studies find that pesticides have health effects, including cancer, with children being the most vulnerable. Some of the pesticides the study detected are banned in other countries.

The chemical trespass (drift) of pesticides is especially concerning because Illinois lawmakers recently rejected a bill requiring advance notification to schools and playgrounds of near-by large-scale pesticide applications. But schools do need advance notification to protect their students - for example, keeping school children indoors or windows shut on spraying days.

By the way, it was lobbying by the chemical industry and conventional farm association that caused the bill to fail. Profits before people!

From Investigate Midwest: Pesticides detected hundreds of feet away from parks and playgrounds in these 10 Illinois counties

Eighteen different pesticide compounds were detected in public parks and playgrounds at 10 sites across Illinois last summer, including some agrichemicals that drifted at least 3,700 feet from the nearest spray site. ...continue reading "Pesticides Drift A Long Way From Where They Are Applied"

Most children in the US are exposed to a wide variety of pesticides, both prenatally and after birth. Pesticides and their residues are in foods, water, rain, fog, interiors of many homes,  gardens, lawns, workplaces, farms - basically everywhere. A recent study of children found that an average of 31 pesticides were found in the urine of each child (infants and toddlers).

In the study 438 urine samples collected from 187 children were analyzed for the presence of pesticide residues. A total of 215 pesticides were identified in the urine samples, with 51 pesticides detected in at least 20% of the samples. Sixteen pesticides were identified as highly detected ones - they were found in over 60% of the samples. On average, there were 31 pesticides per child  - with children ranging from 21 to 50 compounds per sample.

At this time, it is unknown what constant low level exposure to mixtures of pesticides does to a person long-term, but studies done so far are finding harmful health effects. Children are especially vulnerable to pesticides. Unfortunately, when the EPA looks at pesticide exposure, it only looks at one pesticide at a time - not at mixtures.

Health effects: Some pesticides are more hazardous than others, including effects such as endocrine disrupting effects, neurological damage, reproductive effects, and increased risk of cancer. Many scientists suspect that chronic low-level pesticide exposure may even be contributing to the year by year drop in sperm numbers and fertility problems.

Bottom line: Try to lower pesticide exposure by eating organic foods, not using pesticides routinely in yards and in homes (instead use organic products or least toxic IPM), and avoiding antimicrobial, antibacterial, and anti-odor products. [More tips.]

Women are concerned about breast cancer, especially with the cancer rates increasing each year. Many wonder if chemicals in the environment are contributing to breast cancer incidence, and whether there are ways to prevent breast cancer.

A recent study looked at 920 chemicals that can increase breast cancer risk, and  found that exposure to breast cancer promoting chemicals is everywhere. The researchers found that 485 chemicals used in pesticide products, including common consumer goods (e.g., insect repellents, sanitizing products), are linked to breast cancer. Additionally, about 462 of the chemicals have been detected in food, 162 in drinking water, 142 in pharmaceuticals, and 106 in building (construction) materials.

The breast cancer chemical list includes both active ingredients found in pesticides and inert ingredients (which typically are not listed on labels, but can be just as harmful). It includes pesticides used in conventional (non-organic) farming, in outdoor lawn and garden pesticides, pesticides meant for indoor use, lice treatments for children and adults, and flea and tick treatments on pets.

Keep in mind that pesticides applied to crops leave residues, which means they eventually wind up in the foods we eat. And yes, this is why most Americans have detectable pesticides in their bodies (typically blood and urine is tested as part of biomonitoring).

In case you're wondering, the US EPA is not doing a good a job of regulating pesticides and protecting residents of the US - due to persons from the chemical industry or with ties to the pesticide industry (e.g., industry lobbyists) in EPA leadership. And also because laws protecting us have been significantly weakened in the last few years.

Some pesticides banned throughout much of the world (due to their health and environmental risks) are heavily used in the U.S. Noted examples: Atrazine (over 76 million pounds used annually in the US) and paraquat (over 10 million pounds used annually in US).

Bottom line: Try to buy and eat untreated or organic foods. Use unscented or fragrance-free products whenever possible (whether personal care products or cleaning products). Try to avoid using products that say they are "antimicrobial" or "antibacterial". Use least-toxic Integrated Pest Management (IPM) or organic pest control (whether for insects or weeds) both indoors and outdoors.

From The Guardian: New research finds 485 chemicals in US pesticide products linked to breast cancer

New research has identified at least 485 chemicals used in US pesticide products that are linked to breast cancer, raising questions about the safety of food and other products at a time when early onset breast cancer rates are surging worldwide. ...continue reading "Almost 500 Chemicals In Pesticide Products Linked to Breast Cancer"

Human sperm Credit: Wikipedia

A recent study reviewed health effects from pesticide exposure in men. The review of studies on this issue found many adverse health effects from pesticides, including harmful effects on sperm, semen quality, infertility, and other reproductive problems. In other words: male reproductive dysfunction.

Of course, the more exposure, the more problems. And certain types of pesticides have greater effects, including organophosphates (e.g., chlorpyrifos) and carbamates. Unfortunately, the US EPA disregards these reproductive health effects.

Even though study after study finds harmful effects from pesticide exposure, it doesn't seem to be having an impact on use. Billions of pounds of pesticides are applied globally. And residential use (lawn and garden pesticides) continues to be very high.

In fact, recently I've been seeing both homeowner and professional pesticide applications on lawns with one hand holding the pesticide sprayer and the other hand looking at and holding a phone! And no gloves. Yikes! Do they not understand that they are absorbing the chemicals and that there are health effects?

Turf Builder Weed and Feed (with 2,4-D)

Exposure to the weed-killer 2,4-D is very common. This pesticide has been used for many years starting with its use in Agent Orange decades ago, as an ingredient in the commonly used Weed and Feed for lawns, even on genetically engineered crops, and on and on. While the pesticide industry tells you it's safe, many studies have found that exposure to it can cause all sorts of health harms.

A recent study found that exposure to 2,4-D is linked to thyroid cancer in rural counties (where the pesticide is used the most). The researchers think that this may be occurring because 2,4-D is "an endocrine disruptor and may be toxic to the thyroid gland".  They also point out that biomonitoring studies find that in rural agricultural areas people (especially women and children) have higher amounts of 2,4-D in their urine.

As mentioned in the following article, other studies also find that 2,4-D exposure has thyroid effects. It also points out that one study found 2,4-D in the bodies of 1 in 3 Americans, and another study found the presence of both 2,4-D and dicamba (both herbicides) in all pregnant midwest women studied in 2020-2022.

While the United States EPA does not view 2,4-D as carcinogenic (cancer-causing), other countries and international organizations do.

Bottom line: To lower your own 2,4-D exposure, eat as many organic foods as possible, and don't use pesticides on your lawn. Organic crops and organic lawn care does not allow the use of 2,4-D.

Excerpts from Beyond Pesticides: Thyroid Cancer Associated With Exposure to the Weed Killer 2,4-D, Study Finds 

In a study of the herbicide 2,4-D and thyroid cancer in the U.S., researchers find that 2,4-D exposure is significantly associated with greater thyroid cancer incidence in rural counties. Utilizing incidence rates for thyroid cancer for 2017–2021 through the Centers for Disease Control and Prevention (CDC) database and county-level 2,4-D use data from the U.S. Geological Survey, this research, published in Endocrines, highlights a link between pesticide exposure—in areas where agricultural pesticide use is most concentrated—and disproportionate cancer risks. ...continue reading "A Commonly Used Pesticide Is Linked to Thyroid Cancer"

For years it has been known that the pesticide paraquat has serious health effects, which is why it is banned in so many countries - but not the US. But California, the US's largest user of the toxic pesticide, is now the second state to ban the use of the pesticide. It is considered the deadliest pesticide used in agriculture in the US.

Paraquat is a herbicide (weed-killer) that is strongly linked to (causes) Parkinson's disease, and is known to damage the lungs, kidneys. liver, cardiac system, and other bodily systems. While it is banned in more than 70 countries world-wide (e.g., the EU, China, UK, Brazil), the EPA reapproved its use in 2024. More than 10 million pounds annually are sprayed on US crops (e.g., soybeans, almonds, walnuts, cotton), with the most used in California.

Once again, the US is lagging behind other countries in safety and health regulations. Unfortunately, the current EPA is led by persons affiliated with the chemical industry. No wonder it's big industry first in all decisions!

Stories about the toxic pesticide paraquat keep coming. Paraquat is a herbicide (weed-killer) that is strongly associated (causes) Parkinson's disease plus other health harms. This pesticide is banned in over 70 countries world-wide due to its known health harms, but not the US.

California recently took steps to ban the pesticide, but people in New York state are also demanding a ban. The Guardian recently wrote an investigative piece describing the elevated incidence of Parkinson's disease among residents in the rural farming community of Hebron in upstate NY.

The residents want a state-wide ban on the use of paraquat. They say that too many of them have developed Parkinson's disease due to the use of paraquat in their area.

There was a huge blow to anyone concerned with hidden (by pesticide manufacturers) health effects of pesticides this week. Senate Republican members of the Senate Farm Appropriations Committee voted down an amendment to the Senate farm bill that would have enabled lawsuits against pesticide manufacturers when pesticide health effects and harms are revealed.

The amendment, which was proposed by Senator Booker, also stated that if a product causes cancer, it should be on the pesticide label.

The only good news is that the farm bill did not advance out of committee this week. But it will reconsider the farm bill in September. If the farm bill passes as it is written, only what is on pesticide labels can be acknowledged - and it generally just talks about immediate acute effects, such as skin irritation.

Cancer, neurological harms, effects on the fetus, long-term harms, etc. are typically not on pesticide labels, even if pesticide companies know of  harmful health effects (hiding harmful effects is called "failure to warn"). Basically, not allowing consumers to sue pesticide companies is a screw you to Americans.

And yes, the voting was along party lines - Republicans don't want us to be able to sue if health harms are found, while Democrats voted to preserve the right to sue.

One bee among the flowers.

After many days of nothing, finally saw some flying insects among my flowers!

The problem is that many of my neighbors are continuing their obsessions with weed-free carpet-like lawns, and their hatred for any insects - whether beneficial or harmful. Thus, nonstop pesticide applications for lawns, around residence perimeters, and into bushes (e.g., mosquito  treatments using leaf-blower type pesticide applicators).

Cabbage White Butterfly

As a consequence, there are fewer beneficial insects to be found. So far this year I have found only one bee, one cabbage white butterfly (considered a pest by many), and only a few fireflies. It's sad. The brainwashing and marketing by the chemical industry of how frequent applications of pesticides are needed for a "healthy lawn and garden" is very powerful.

But I also found one insect I'm sorry to see - a deer tick.

Cardinal flower

Haven't seen any bees or butterflies this past week. Not on flowers, not among the clover. None. All I can do is document the devastating effects of neighboring pesticide applications on pollinator populations in my organic suburban property.

A neighbor has had numerous applications by 3 services(!) for several years - on the lawn, in the garden, on plants around the house, the exterior of the house, and the hedges between properties. Basically everywhere, typically every 3 weeks. Of course, the pesticides drift to neighboring properties (mine!).

The worst for pollinators (bees, butterflies) appear to be the mosquito applications using a device that looks like a leaf blower, which is held at waist-height - these are high-volume applications. The mosquito applications are done using cypermethrin and pyrethroid insecticides (which are synthetic pesticides, e.g., made by Fendona). Pyrethroids are known to be highly toxic to pollinators such as bees and wasps, and there is growing evidence of harms to humans (here, here).

One study confirmed that pesticides are a major reason that wild bee populations are significantly down in the US. The researchers found that bee species are about 43% down in areas of heavy pesticide use. They singled out pesticides (insecticides) such as neonicotinoids and pyrethroids as drivers of this bee species reduction. They pointed out that using Integrated Pest Management (IPM) or organic methods would help reduce pesticide use and so help with bee species populations.

This means that businesses (e.g., Mosquito Joe) that apply long-lasting pyrethroids throughout suburban yards and hedges in the US are contributing directly to bee species reduction.

Other studies found that applying pesticides (no matter what kind) to lawns destroys bee populations and reduces the number of bee species. Think of lawns that are not treated with pesticides as having wildflowers, not weeds. These are bee habitats!
