Pesticides not killin' just bugs...

U.N. report estimates pesticides kill 200,000 people per year
March 9, 2017 - Overwhelming majority of those killed are farmers in the developing world
Quote:
Seeking to draft a global treaty banning the use of dangerous pesticides, a United Nations report presented Wednesday estimated 200,000 people globally die each year as a result of chronic exposure to agricultural chemicals.

The report's authors, Hilal Elver and Baskut Tuncak, both special rapporteurs to the U.N. on food and toxins respectively, said those affected are almost all farmers in the developing world. They condemned the widespread use of dangerous pesticides in a presentation to the U.N. Human Rights Council. "Excessive use of pesticides are very dangerous to human health, to the environment and it is misleading to claim they are vital to ensuring food security," they said.


Tropical smallholder farmers do not always use protective gear while handling pesticides, as this undated photo shows. A new report presented to the United Nations Human Rights Council said 200,000 people per year, mostly in developing countries, die as a result of exposure to toxic pesticides.

Excessive long-term exposure to the chemicals has been linked to a long list of potentially fatal illnesses, from cancer to Alzheimer's disease. Their report stated 99 percent of deaths associated with pesticides happen in third-world countries where regulations governing their use are extremely lax or nonexistent. Particularly at risk are children who are forced into labor at an early age and are more susceptible to medical problems as a result of chronic pesticide exposure.

There are currently international provisions protecting the use of some pesticides as part of existing law governing the international use of chemicals, but there is no such treaty to govern which chemicals should not be used in the agricultural process, the researchers said. "Without harmonized, stringent regulations on the production, sale and acceptable levels of pesticide use, the burden of the negative effects of pesticides is felt by poor and vulnerable communities in countries that have less stringent enforcement mechanisms," they said.

Default Re: Pesticides threaten birds and bees alike: study

Leave it to walt to dredge up a thread from three years ago, but thanks.

I would like to suggest to anyone who doesn't believe synthetic fertilizers and pesticides have a long term damaging effect on land, air and water, have a quick read.

And they wonder why the bees are dyin' off...

Not So Sweet: 75 Percent of Honey Samples Had Key Pesticide
October 05, 2017 > When researchers collected honey samples from around the world, they found that three-quarters of them had a common type of pesticide suspected of playing a role in the decline of bees. Even honey from the island paradise of Tahiti had the chemical.

That demonstrates how pervasive a problem the much-debated pesticide is for honeybees, said authors of a study published Thursday in the journal Science. They said it is not a health problem for people because levels were far below governments' thresholds on what's safe to eat. "What this shows is the magnitude of the contamination," said study lead author Edward Mitchell, a biology professor at the University of Neuchatel in Switzerland, adding that there are "relatively few places where we did not find any." Over the past few years, several studies — in the lab and the field — link insecticides called neonicotinoids, or neonics, to reduced and weakened honeybee hives, although pesticide makers dispute those studies. Neonics work by attacking an insect's central nervous system.


Volunteers check honeybee hives for queen activity and perform routine maintenance as part of a collaboration between the Cincinnati Zoo and TwoHoneys Bee Co. at EcOhio Farm in Mason, Ohio

Bees and other pollinators have been on the decline for more than a decade and experts blame a combination of factors: neonics, parasites, disease, climate change and lack of a diverse food supply. Honeybees don't just make honey; about one-third of the human diet comes from plants that are pollinated by the insects. Bees pick up the pesticide when they feed on fields grown from treated seeds. As part of a citizen science project, the Swiss researchers asked other experts, friends and relatives to ship them honey samples. More than 300 samples arrived and researchers tested 198 of them for five of the most common types of neonics. Overall, 75 percent of the samples had at least one neonic, 45 percent had two or more, and 10 percent had four or more.


St. Thomas More Academy students sample honey sticks during a tour of the Bayer North American Bee Care Center in Research Triangle Park, N.C.

Results varied by region. In North America, 86 percent of samples had the pesticide; Asia, 80 percent; Europe, where there's a partial ban, 79 percent; Africa, 73 percent; the Australian region, 71 percent and South America, 57 percent. The study found that nearly half of the honey samples exceeded a level of the pesticide that some previous research said weakens bees, but the pesticide makers say otherwise. An outside expert, University of Nebraska's Judy Wu-Smart, said the study used too few honey samples to make the broad conclusions the researchers did. Ann Bryan, spokeswoman for Syngenta which makes the neonic thiamethoxam, said the amount of the pesticide found in honey samples "are 50 times lower than what could cause possible effects on bees." Jeffrey Donald, a spokesman for Bayer Crop Science which makes the neonic clothianidin, said the study "perpetuates the myth that exposure to low levels of neonicotinoids implies risk, even though there is no compelling scientific evidence to support this conclusion."

The study authors likened neonics to DDT, the pesticide in the 1960s linked to declines in bald eagles and other birds. They said neonics are dangerous to all sorts of insects, even ladybugs. University of Illinois bee expert Sydney Cameron and other scientists said those comparisons aren't right because neonics don't stay in an animal's system like DDT did and are applied to seeds and not sprayed in mass quantities. "This is an important paper if for no other reason that it will attract a great deal of attention to the mounting problem of worldwide dependence on agrochemicals, the side effects of which we know relatively little," Cameron said in an email. She wasn't part of the study. One side benefit of collecting honey is that researchers could sample some. Mitchell's favorite is a dark and bitter honey from Africa. He called the honey fantastic, but added "I couldn't eat it all the time. It was just too strong."
