Synopsis: 5. medicine & health: Toxicity & poisons:

scientists are developing multiple mixing ponds as wetlands to reduce the toxicity of the brine as well as to cultivate habitat.

and they will go to any lengths to protect them oe including poisoning or killing the hungry beasts.

it's the dose that makes the poison, and a laundry list of ingredients is a poor way of assessing a product's true risk.

chemical companies must provide extensive toxicity data to prove it is safe for indoor use,

acid rain poisoned rivers, lakes and soils, eroded buildings and monuments; refrigerant chemicals ate away at the protective ozone layer;

and producing a deluge of toxin and plastics waste that will take centuries to degrade.

however, inappropriate flooding of vegetation can cause greenhouse gas emissions and poison the water for fish.

with claims that Turing poisoned it so he could mimic the one in his favourite fairytale, Disney's Snow white,

and charcoal contains several toxic substances, including carbon monoxide, heavy metals and tar. Some water-pipes are sold with mouthpieces containing cotton filters or a plastic mesh.

which the authors say could have been the early stages of carbon monoxide poisoning. But what do we know about any long-term consequences?

But the floral nectar of some plant species also includes small quantities of substances known to be toxic,

Midwest and South are being forced to spray fields with more toxic herbicides, pull weeds by hand

But she is now back on her feet after trying a treatment called Bee Venom Therapy (BVT.

Experts believe the venom in the sting helps ease the pain of MS symptoms and also stimulates the body to fight back Sami says she was stung around 1,

Bee Venom Therapy, or Apitherapy, uses the stings of live bees to relieve symptoms of MS such as pain, loss of coordination,

Researchers suggest that certain compounds in bee venom reduce inflammation and pain and a combination of all its ingredients helps the body to release natural healing compounds.

But the floral nectar of some plant species also includes small quantities of substances known to be toxic, such as caffeine and nicotine.

What weve shown is clearly not proof of toxicity, but signs of toxicity, he told New Scientist magazine.

Im sure theres no acute toxicity but whos to say there are no chronic effects? The experiments were carried out by Monsanto researchers on three strains of GM maize.

Two of the varieties contained genes for the Bt protein which protects the plant against the corn borer pest,

she said. oemany people think the scorpions are poisonous but when a scorpion dies it is not longer venomous.

but we do cut off the stinger just to make sure there is no hint of poison. oewe feed the worms things like oatmeal,

Today, Spanish fly is considered actually a poison, as an overload of cantharides can cause kidney malfunction, gastrointestinal hemorrhages or even death.

Wild turkeys have a gene that makes them resistant to a type of toxic fungus sometimes found in corn and soybeans.

This toxin can be deadly on its own or lower a turkey s resistance to other infections and cause death that way.

then you can have these birds again more resistant to the toxin, #said Dalloul. No natural matingeven the intended consequences of commercial turkey breeds have introduced complications.

and other toxic chemicals,#said Dr. Phillip Landrigan, director of the Childrens Environmental Health Center at Mount sinai School of medicine in New york city.

and as a defense mechanism, the plant will shoot out a poisonous spay. But are plants trainable?

But even still, many fear the toxicity of DEET and try to avoid it even with those mini-monsters landing on you noon and night.

Children with DEET toxicity reported lethargy, headaches, tremors, involuntary movements, seizures, and convulsions though the amount that led to this toxicity was unreported, according to the CDC.

#Explosives and Pesticides Can Be detected by Using Bee Venom MIT scientists discover that bee venom can detect explosives and some pesticides.

Scientists from MIT have discovered that by coating carbon nanotubes in bee venom, they can create ultra-sensitive detectors for explosives such as TNT,

as well as at least two different types of pesticides. This means that bees and their stingers could become important to making better environmental sensors.

and fellow chemical engineers coated one-atom-thick tubes of carbon with protein fragments found in bee venom,

Its certainly an interesting use of venom especially after we recently saw that scorpion venom can be used to create pesticides.

Strano has filed for a patent on the sensor, and the team is still working out a compression system to ensure that any molecules in the air come into contact with the tubes

This is certainly a novel approach for using the proteins found in bee venom. It seems there are a number of potential uses for the poison,

even including boosting brain functions like memory and learning. Photo credit: Flickr Via Treehugger Share Thissubscribedel. icio. usfacebookredditstumbleupontechnorati e

Between 1999 and 2003, EPA put in place restrictions on the most toxic organophosphate pesticides on crops and in homes.

#10 Everyday Fruits and Vegetables that are Poisonous Even apples have a poisonous element. Most of us think that eating fruits

Poisons that make you sick, paralyze and even kill you lurk behind some of our favorites#10.

but lately there has been a fad by teens to get high on nutmeg#with very unhappy results. 7. Kidney beans Kidney beans contain the toxin phytohaemagglutinin,

These beans become five times more toxic when heated to the temperatures used in slow cooking than they are when raw,

though while it is not poisonous to humans, the ingredient theobromine is dangerous to dogs and cats.

and vines of tomato plants contain alkaloid poisons such as atropine that cause dizziness, headaches and upset tummies.

Its the theobromine that is poisonous to dogs in sufficient quantities. But it takes, on average, a fairly large amount of theobromine to cause a toxic reaction#For more specific figures,

here are the approximate amounts of theobromine per ounce of chocolate: Cocoa powder: 800 mg/oz Bakers chocolate (unsweetened:

50 mg/oz So, the general rules for the amount of chocolate that will be toxic for a dog:

it would take about 200 pounds of white chocolate consumed within a 17 hour period to reach toxic levels of theobromine for a 16 pound dog.

In Ireland, for example, the countrys poison center reported 17 cases of possible side effects between 1999 and 2005,

How many people take the time to call a poison control center when they dont feel well?#

#While the U s. poison control centers havent been able to track potential side effects from energy drinks in the past,

more toxic pesticides being used on our farmland, and seeping into the groundwater. This, in turn, puts farm workers in danger#a Swedish study recently concluded that the application of Roundup doubles farm workers and and rural residents risks of getting cancer.

It makes the plant toxic to certain insects if they eat the sap. However scientists fear that the systemic chemical also makes it into the plants pollen

This technology could also sniff out minuscule amounts of environmental toxins before they hit critical mass,

Wild mint fights gingivitis and gastrointestinal disorders; rosemary is used as a remedy for gout; artemisia is thought to improve blood circulation.

It effectively eliminates the need for additives and many other toxic and ineffective products. Dragon Juice is one of the featured exhibitors at the Davinci Inventor Showcase,

and the chemicals used in fire extinguishers can be toxic (halons, the most effective chemical fire suppressant, create holes in the ozone layer.

They re also attracting chemicals and environmental toxins, which are getting passed along in breast milk.

Writer Florence Williams read a research study about toxins found in human breast milk when she was nursing her second child.

and how toxins from the environment may be affecting hormones and breast development. She says many of those toxins,

including the flame retardants found in her breast milk, may come from ordinary household items like couches and electronics,

with farmers and villagers chopping them in half out of the mistaken belief that they are poisonous snakes.

Spotted salamanders exposed to contaminated roadside ponds are adapting to their toxic environments, according to a Yale paper in Scientific Reports.

As roadside ponds become more toxic, the surviving salamanders may develop a genetic advantage over their counterparts living in woodland ponds.

#Researchers say sugar should be regulated as a toxin Sugar and other sweeteners are so toxic to the human body that they should be regulated as strictly as alcohol by governments worldwide, according to researchers.

A spoonful of sugar might make the medicine go down. But it also makes blood pressure and cholesterol go up,

#7 Science Careers You Never Knew Existed Snake venom handler? Sex scholar? A career in science doesn't have to mean a job in a dank lab or cubicle.

Snake milkers are animal care specialists who extract the venom of poisonous snakes. Snake venom while not exactly milk is nevertheless a life-giving substance (when used correctly.

The venom deadly on its own is the main ingredient in snakebite antidotes and a wide range of medicines.

Snake milkers have the job of extracting or milking the toxic substance from a snake's fangs.

The venom can be made into a freeze-dried powder that research laboratories use to produce drugs for blood clots heart attacks and high blood pressure.

Scatologist It isn't the most glamorous of careers but scatology the scientific study of excrement can tell scientists a lot about an animal including its habits overall health and presence of disease.

Coupled with the public outcry over the thick blanket of toxic smog that covered Beijing earlier this year there are glimmers of hope that the Chinese people may succeed in wresting some measure of control over their environment and their lives back from government and industry leaders.

The toxic element is likely blowing in from mining operations in neighboring countries Larsen said.

Top 10 Unexplained Phenomena We couldn't find anything toxic in their stomachs and no toxic plants on the landscape said Kerry Mower a wildlife disease specialist with New mexico Department of Game

The Basic Science of Poisons (Mcgraw-hill Professional 2013. Under these conditions one species of alga Anabaena flos-aquae produces a neurotoxin anatoxin-A which depolarizes and blocks acetylcholine receptors causing death in animals that drink the pond water.

And the fast-acting toxin explains the animals'strange sudden deaths. In this case the algae appeared not in ponds

Based on circumstantial evidence the most logical explanation for the elk deaths is that on their way back to the forest after feeding in the grassland the elk drank water from a trough containing toxins created by blue-green algae

The algae-produced neurotoxin is similar to curare the famous toxin found in poison-tipped arrows used by South american indian tribes.

Additionally Michael Jacobson executive director of the Center for Science in the Public interest said there is no safety hazard in using genetically modified soybean oil over conventional soybean oil a finding the organization highlighted recently in its Nutrition Action newsletter.

or they are resistant to a pesticide like Roundup (manufactured by Monsanto Corp.).One widely used method of incorporating insect resistance into plants is through the gene for toxin production found in the bacterium Bacillus thuringiensis (Bt) according to the World health organization.

Officials attributed the deaths to toxic levels of ammonia dumped into the river from a local chemical factory.

The No. 1 offender is called a drug methylene blue used to treat carbon monoxide poisoning and as a dye during surgery.

and toxic rat poison other studies have shown. Rare predator species such as spotted owls and fisher cats eat the poisoned mice and die.

The marijuana cultivators make trail systems to go in and put toxicants at every clearing said Mourad Gabriel a University of California Davis wildlife disease ecologist who studies the effects of rodenticides on rare species. A lot of predators will use any type of trail system

Earlier studies by the USGS researchers found toxic pesticide concentrations in several frog species living in the national parks. In 2009 and 2010 the scientists resurveyed many of the same sites Smalling said.

Toxic pot gardens Most pesticides in the Sierras come from the Central Valley. The pesticides travel to the mountains as aerosols tiny particles that waft into the atmosphere on warm rising air currents.

The cultivators spray pesticides and fertilizers and spread rat poison. Rodents that eat the poison live for two to seven days before keeling over giving predators plenty of time to capture their dazed prey.

UC Davis'Gabriel and his colleagues are seeing the effects of these chemicals on the fisher cat a carnivore being considered for Endangered Species Act listing.

The scientists found rat poison in 85 percent of fisher cat carcasses collected on public and tribal lands according to a study published in June in the journal Conservation Letters.

The animals are also passing the poison on to their kits when the babies nurse Gabriel said.

#Poisons and Panaceas: Plants Tell History of Healing NEW YORK Modern medicine owes a great debt to botany.

Rosy periwinkle too is toxic to eat but has been used to treat ailments from diabetes to constipation in traditional Indian and Chinese medicines.

When he called his local poison control center and explained his story the operator told him to call plant expert Michael Balick of the New york Botanical garden.

He said he was cleared of any possible toxic effects by the next day. Are herbs safe?

and veggies for city dwellers but high levels of toxic metals in soil especially lead could pose health risks for people who grow

Toxic metals such as lead zinc and cadmium are commonly found in soil particularly in urban areas.

However the bulk of the research on toxic metals has focused on lead since lead poisoning is the number one environmental threat to children in the United states. Sources of lead in soil include past industrial activities flaking lead paint from old houses and emissions from leaded gasoline.

Though the United states phased out leaded gasoline in cars and trucks during the 1970s and 1980s soil in high-traffic

Soil in urban gardens may be contaminated with toxic metals especially lead. This story was provided by Myhealthnewsdaily a sister site to Livescience.

Others have speculated that some of the deaths may be attributed to toxic molds or bacteria that were disturbed

but also makes the food toxic and less digestible. In raw vegan parlance cooking is killing.

In reality toxins can accumulate anywhere in the body particularly in fat and fatty tissue but also in proteins and bone.

The colon is surprisingly low in toxins however. As for the liver the confusion is that this organ filters toxins

and must therefore the reasoning goes be loaded with toxins. But the liver is more of a chemical-processing plant than a filter;

it breaks down toxins as they pass through. That is the liver doesn't have extra toxins by virtue of it being the body's natural toxin-neutralizer.

Wishful thinking: 6'Magic bullet'Cures That Don't Exist Another argument is that burning fat in this case on a raw vegan diet would release toxins from the body.

But fat cells don't burn up as if into ashes liberating their contents. Fats cells merely get bigger or smaller depending on the amount of fat within the cell that's used.

It is unclear how much of a toxin if any would be set free if the fat molecule it is attached to is burned.

The toxin is now free to attach to other fat molecules. If it does mobilize with other recently liberated toxins in the case of extreme starvation then the toxin could become toxic

and overwhelm the liver. In short there are no foods or herbs that can magically bind and pull toxins from your blood or organs.

The same would be true for cows or for any vegan animals that accumulate toxins in their fat;

they don't cleanse themselves with their raw plant-based diet. At best detoxification schemes (juicing fasting) can help by virtue of not placing more toxins in our body for a day or two.

And a healthful plant-rich diet with plenty of water can in general help your liver

and kidneys process and remove toxins more effectively Mcdougall said. Misconception#4: Raw veganism is healthful Healthfulness

#Sipping Tarantula Venom Kills Crop-Eating Insects The venom in a tarantula's fangs packs a lethal punch

But the toxic brew could also serve as an insecticide against agricultural pests that consume the venom orally a new study finds.

A component of the spider venom is especially effective against the cotton bollworm a pest that attacks crop plants.

In the last decade researchers have been investigating bioinsecticides proteins derived from natural sources such as spider venom.

The World's Creepiest Spiders In the study researchers milked venom from Australian tarantulas (Selenotypus plumipes)

When ingested by insects the poisonous chemical called orally active insecticidal peptide-1 was as toxic as the synthetic insecticide imidacloprid the group reported today (Sept. 11) in the journal PLOS ONE.

A combination of the venom peptide and synthetic insecticide was even more effective. The venom was more potent against cotton bollworms than against termites and mealworms

which eat stored grains rather than crops results showed. Venoms from other insect-eating animals such as centipedes and scorpions may also contain peptides that could be used as bioinsecticides.

Or scientists could genetically engineer insect-resistant plants or microbes that produce these toxins. The breakthrough discovery that spider toxins can have oral activity has implications not only for their use as bioinsecticides

but also for spider-venom peptides that are being considered for therapeutic use study researcher Glenn King of the Institute for Molecular Bioscience at the University of Queensland Australiaâ said in a statement.

S. plumipes is one of Australia's largest spiders but is not harmful to humans.
