Poisons and Toxins
Poisons are chemicals that adversely affect living organisms at the molecular level. Regardless of whether they're inhaled, absorbed, or digested; targeted toward a specific organism or broad in scope; or whether they're acute or chronic, a large enough dose of poison will result in severe illness or death. Please direct all questions regarding poisons, including their chemistry, uses, control, effects, and antidotes, into this category. If you are having an immediate issue with a possible poisoning, you should contact your local poison control or emergency medical center right away.

Yes, californium is a radioactive element and can be harmful if ingested or inhaled. Exposure to californium can result in radiation sickness, which may cause severe health effects. Proper handling and containment measures are necessary when dealing with californium.
What does Mercury poisoning do?
poisoning from elemental mercury is most likely due to inhalation of mercury vapors. The danger lies in the fact that after it is inhaled into the lungs in vapor form, mercury passes into the blood stream.
Is T2 toxin a polar mycotoxin?
According to
Tapani Tuomi, Lauri Saarinen and Kari Reijula (1998): Detection of polar and macrocyclic trichothecene mycotoxins from indoor environments. Analyst, 123, 1835-1841
T-2 Toxin belongs to the polar mycotoxins.
In a food pyramid where are most of the toxins found?
The top of the food chain.
As organisms consume other organisms, the toxins are all passed up in the food chain. Therefore, the top of the food chain will have the highest concentration of toxins.
Is silver potassium cyanide poison?
Yes, silver potassium cyanide is highly toxic. It can release toxic hydrogen cyanide gas if it comes into contact with acids or water, leading to serious health risks if inhaled or ingested. Proper safety precautions should be taken when handling this compound.
If your asking if the pencil has Lead, then the answer is that most pencils do NOT have lead in them anymore.
Is scolopendra dalmatica dangerous for humans and what happens if it bites you?
Answer:
Caution: If anything bites you, go straight to a doctor.
More Information:
Scolopendra dalmatica is a species of centipede and its venom is dangerous and can be dangerous to humans, if you are exposed to it, you should seek medical assistance as quickly as possible. In case of a severe reaction, you probably would want to be where there is immediate help for you. At a minimum, their venom will cause a painful experience, with attendant swelling and severe discomfort for hours.
However, while all centipedes are venomous, their venom is not generally considered to be life-threatening to humans. It is also true, though, that different people react differently to venom. Though the odds may be low, centipede venom might possibly be life-threatening to you. Further, if you already suffer from allergies, the odds of a more serious event are higher for you.
It should also be noted that there are approximately 202 species of Scolopendra, so we may not know all there is to know about the toxicology of all of them. So, in the event of a bite by one, see a doctor right away.
What is the difference between a toxin and poison?
The way that toxic materials are defined is by how well they kill rats. This is called the "Median Lethal Dose" or LD50. It is usually expressed as "LD50, Oral, Rat" meaning that the subjects were specially bred, white, Norway rats and the dose was given by mouth. The dose is presented as milligrams per kilogram of rat.
- The U.S. EPA and OSHA define a toxin as a substance that has an LD50 of 500 mg/Kg or less. Acutely toxic materials have an LD50 of 50 mg/Kg or less.
- The U.S. DOT defines poison as a substance with an LD50 of 200 mg/kg or less.
Naphthalene is primarily found in coal tar and in some volcanic gases. It is also released into the environment from the burning of fossil fuels, cigarette smoke, and forest fires. Additionally, naphthalene is used in mothballs and some air fresheners.
Does sweat remove toxins from the body?
The liver and kidneys, not the sweat glands, are the organs responsible for the filtration of toxins from the blood.
There is widespread belief that sweating, e.g. in a sauna, helps the body to remove toxins, but the belief is without scientific support.
Sweat does contain trace amounts of toxins but definitely won't help clear the body of mercury or other metals. Almost all toxic metals in the body are excreted through urine or feces. Less than 1% are lost through sweat.
Sweating for the sake of sweating (e.g. sauna "treatments") has no benefits. In fact, heavy sweating can impair your body's natural detoxification system due to dehydration.
I dont know if I would say poisonous. As far as I know there is only one oxide that is not radioactive. I ingested this for 30 days 10 yrs later i am still here, although I believe it has harmed me.
Too much of anything--even water--can be poisonous. People have died from drinking too much, its called water intoxication.
Nitroglycerin, used in VERY small amount, can be a medicine used to dilate blood vessels. Like with any medicine, if one were to consume too much, it will hurt, or possibly kill them.
How poison considered a poison?
The fields of medicine (particularly veterinary) and zoology often distinguish a poison from a toxin, and from a venom. Toxins are poisons produced via some biological function in nature, and venoms are usually defined as toxins that are injected by a bite or sting to cause their effect, while other poisons are generally defined as substances absorbed through epithelial linings such as the skin or gut.
Some poisons are also toxins, usually referring to naturally produced substances, such as the bacterial proteins that cause tetanus and botulism. A distinction between the two terms is not always observed, even among scientists. Animal poisons that are delivered subcutaneously (e.g. by sting or bite) are also called venom. In normal usage, a poisonous organism is one that is harmful to consume, but a venomous organism uses poison (venom) to kill its prey or defend itself while still alive. A single organism can be both venomous and poisonous. The derivative forms "toxic" and "poisonous" are synonymous.
In nuclear physics, a poison is a substance that obstructs or inhibits a nuclear reaction. For an example, see nuclear poison. Paracelsus, the father of toxicology, once wrote: "Everything is poison, there is poison in everything. Only the dose makes a thing not a poison." The term "poison" is often used colloquially to describe any harmful substance, particularly corrosive substances, carcinogens, mutagens, teratogens and harmful pollutants, and to exaggerate the dangers of chemicals. The legal definition of "poison" is stricter. A medical condition of poisoning can also be caused by substances that are not legally required to carry the label "poison".
Environmentally hazardous substances are not necessarily poisons and vice versa. For example, food industry wastewater-which may contain potato or milk juice-can be hazardous to the ecosystems of streams and rivers by consuming oxygen and causing eutrophication, but is nonhazardous to humans and not classified as a poison.
Americium is radioactive:
The radiation from exposure to americium is the primary cause of health effects from absorbed americium. Americium moves rapidly through the body after uptake and is concentrated within the bones for a long period of time. During this storage americium will slowly decay and release radioactive particles and rays. These rays can cause alteration of genetic materials and bone cancers.
Damage to organs due to americium exposure is highly unlikely for humans, because americium is accumulated in organs only a short period of time.
Salt is a compound made of two elements: sodium and chlorine. It is scientifically named as sodium chloride, and the symbol is Na+Cl-. The type of the bond is ionic.
Chlorine is a poisonous substance that exists as a greenish gas at room temperature. But when it bonds with sodium, it gains an electron from sodium. This small change results in becoming safe to eat when bonded to sodium.
There isn't a specific color associated with poison, as it can come in a variety of colors depending on the substance. It's important to focus on other signs and labels to identify poisons accurately.
What are 4 ways in which microorganisms can damage the body?
Microorganisms that are part of the body's normal flora play many roles in the body some of them are still undefined, but here are a few examples of what microorganims do:
1. Immune defense: They compete with pathogenic bacteria and prevent pathogenic bacteria from growing.
2. Digestion: They help digest and break down food in your small and large intestines which your body can use. People who have problems digesting certain kinds of food usually have the wrong balance of microorganisms.
3. Production of useful compounds; Bacteria make vitamin K and anti-inflammatories as well as many other useful compounds.
How does activated charcoal remove poison from a person's body?
Activated charcoal works by binding to toxins in the gastrointestinal tract, preventing them from being absorbed into the bloodstream. This helps to limit the impact of ingested poisons by reducing their bioavailability and facilitating their elimination from the body through feces. It is important to administer activated charcoal soon after ingestion to be effective.
Cyanide rotenone and dinitrophenol are often referred to as respiratory poison?
Cyanide, rotenone, and dinitrophenol are considered respiratory poisons because they disrupt the process of cellular respiration by targeting different components of the electron transport chain. This interference prevents the production of ATP, the cell's main energy source, leading to cell death. Cyanide inhibits cytochrome c oxidase, rotenone inhibits complex I, and dinitrophenol disrupts the proton gradient across the inner mitochondrial membrane.
What is the fastest way to absorb poison?
The fastest way to absorb poison is to seek medical help immediately. Depending on the type of poison, treatment may include administering activated charcoal, inducing vomiting, or using specific antidotes. Do not attempt to self-treat or use home remedies as they may worsen the situation.
Is carbon in silverware dangerous to ingest?
Well honestly if it was, then we would all probably be dead. It shouldn't be harmful, considering it goes through a dish washer and when they first make the silver in a factory they only put the carbon in them in order to hold there shape. They go through a series of test first to make sure no chemical is unbalanced. so don't worry about it.
Answer:
If by silverware you mean eating utensils made of Sterling Silver, there is no carbon in silverware. Sterling Silver contains (by law) 92.5% pure silver and 7.5% of other metals - typically copper.
If by silverware you follow the American custom of calling all flatware "silverware" you might include iron, steel, German Silver, or stainless steel in the materials present. Of these, only the iron and steel items would contain carbon. In those alloys the carbon is bound tightly with the metal and will not be released.
As far as the toxicity of pure carbon - it isn't toxic. Well done steaks and toast would be very unpopular if carbon were toxic.
Ozone can be a deadly poison when inhaled in high concentrations because it can irritate and damage the respiratory system, leading to breathing difficulties and exacerbating conditions such as asthma. Prolonged exposure to high levels of ozone can also cause lung inflammation and decrease lung function, increasing the risk of respiratory illnesses and other health problems.
