Polonium-210 is a metal found in uranium ore, which often shows up as a byproduct of nuclear reactors. It can be processed into a tasteless, odorless compound that dissolves in water, which makes it a good candidate as far as undetectable poisons go.
Thallium is tasteless and odorless and has been used by murderers as a difficult to detect poison. It is found in trace amounts in the earth's crust.
Most poisons can be detected in your blood or urine. Your doctor may order a toxicology screen. This checks for common drugs using a urine or saliva sample.
The odorless and tasteless thallium sulfate was also used as rat poison and ant killer. Since 1975, this use in the United States and many other countries is prohibited due to safety concerns.
Unless there is a possibility or suspicion of a specific poison, the chances of discovery are almost none.
The urine test is the most reliable test for arsenic exposure within the last few days. Urine testing needs to be done within 24–48 hours for an accurate analysis of an acute exposure. Tests on hair and fingernails can measure exposure to high levels of arsenic over the past 6–12 months.
Once at the laboratory, a series of tests will be conducted, usually on blood, for a large range of over-the-counter, prescription and illicit drugs as well as alcohol and other toxicants; e.g., metals, inhalants, environmentals (pesticides, insecticides), carbon monoxide, cyanide and many other possible toxins ...
There are several methods used to test blood and urine for anticoagulant rodenticides. But many of the methods are time consuming or inefficient. Part of the problem is how the sample is cleaned up before analysis.
Place these easy-to-use pellets around landscaping, near livestock or poultry housing, or under buildings or garden structures. RatX® works from the inside out to exterminate rats and mice, then dries them out after death to reduce odor by as much as 90%.
To do this, add 25-30 drops of peppermint essential oil to a cotton ball and place it to places where rats are commonly found. Peppermint kills the rats as soon as it gets in contact with their lungs, it shrinks it and eventually kills the rats. 2.
Pål Stenmark regards botulinum toxin – the world's most dangerous poison – as a set of building blocks he can redesign and give new functions. One aim is to produce new and more effective pharmaceuticals, including pain treatments.
Carbon monoxide (CO) is a gas that can kill you quickly. It is called the “silent killer” because it is colorless, odorless, tasteless and non- irritating. If the early signs of CO poisoning are ignored, a person may lose consciousness and be unable to escape the danger.
There are no specific clinically validated assays for detection of ricin that can be performed by the hospital/healthcare facility clinical laboratory. No methods are available for the detection of ricin in biologic fluids.
Strychnine is a white, odorless, bitter crystalline powder that can be taken by mouth, inhaled (breathed in), or mixed in a solution and given intravenously (injected directly into a vein). Strychnine is a strong poison; only a small amount is needed to produce severe effects in people.
FASTRAC with Bromethalin is Bell's newest and fastest acting rodenticide. An acute bait, FASTRAC kills rats and mice in one or two days, often within 24 hours! As an added plus, rodents stop feeding after eating a lethal dose, saving you money and bait. More rats and mice can be controlled with less bait.
Brodifacoum - This is probably the 'strongest' poison you are likely to buy. It is a single feed bait, which means that the offending mouse or rat will consume a lethal dose at the first time of feeding.
When rats are dying from poison, they will sometimes come out into the open in search of water due to severe dehydration. However, they are often too weak to leave their lairs and die within walls or other out-of-reach places.
For the best rodent control, baits should be refreshed after 12 months or just before the colder times of the year when new rodents can be expected to investigate your property.
Indeed arsenic trioxide was the perfect murder weapon in that its symptoms of vomiting and diarrhoea were very like those of many common ailments, so that even doctors were unlikely to diagnose arsenic poisoning as the cause of an illness or death, and surgeons who carried out autopsies were unlikely to find evidence ...
Most arsenic compounds are undetectable to the senses, since they have no smell or taste. But when arsenic is heated – by bright sunlight or in a laboratory experiment – it passes directly from its solid state to a gas and gives off a distinctive garlic odor.
Along with hair and urine, postmortem tissues including paraffin tissue blocks and even cremated ashes have been used to confirm elevations of thallium in suspected criminal poisonings.
