The fastest route for a toxic substance to enter the body is through inhalation, where the substance is absorbed directly into the bloodstream through the lungs. This route allows for rapid delivery of the toxic substance to the bloodstream and major organs.
Chemicals are absorbed through the skin or eyes through the dermal route of entry. Skin absorption occurs when chemicals come into direct contact with the skin, while eye absorption occurs when chemicals get in contact with the eyes. Both routes can lead to absorption of chemicals into the bloodstream.
The most common exposure route for a toxin in humans is ingestion, which occurs when a person swallows or consumes a substance contaminated with the toxin. Other common exposure routes include inhalation (breathing in the toxin) and dermal contact (absorbing the toxin through the skin).
IM means Intramuscular route of drug administration, while IV means Intraveinal route of drug administration. IV route, takes the drug directly into the bloodstream resulting in 100% bioavailability instantly. Where as in IM route, drug is injected into muscle tissues, which holds the drug for a while and gradually releases into the bloodstream through the network bed of capillaries running across or surrounding the muscle tissue. In IM, the bioavailability may be slightly less than 100% of drug due to diffusion from muscle through tissue fluid and into the blood.
Nitrate poisoning symptoms can appear within minutes to hours of exposure, depending on the amount and route of exposure. The duration of symptoms can vary based on the severity of exposure and individual factors. Ammonium Nitrate from skin contact with ANFO can be absorbed through the skin, and elimination from the body depends on various factors but typically takes several hours to days. Immediate decontamination and seeking medical advice is important for both situations.

"Although not a common route of exposure for poisons, injection is the only route in which the entire amount exposed is absorbed regardless of the chemical administered, because the chemical is introduced directly into the body."........ "Ingestion is the most common route of exposure to toxic chemicals. Most chemicals diffuse across the cell membrane in the nonionized form, so that the degree to which the chemical is ionized is important in determining whether a chemical is absorbed"http://www.britannica.com/EBchecked/topic/466463/poison/28085/Routes-of-exposure-and-absorption-of-chemicals
The route of administration of Nitrostat is sublingual
Even small amounts of mercury can be harmful to human health. The toxic effects depend on the form of mercury and the route of exposure, but generally, levels above 5 micrograms per liter of blood are considered concerning. Chronic exposure to lower levels can lead to serious health issues, including neurological and developmental problems. It’s important to minimize exposure, as there is no safe threshold for mercury in the body.
Chemicals are absorbed through the skin or eyes through the dermal route of entry. Skin absorption occurs when chemicals come into direct contact with the skin, while eye absorption occurs when chemicals get in contact with the eyes. Both routes can lead to absorption of chemicals into the bloodstream.
The primary route is in the intestines. However, it is also absorbed in the mouth, throat and stomach.
INHALATION
Ingestion is a route of exposure that is not as widespread in industry compared to inhalation and dermal exposure. This is because industrial processes are typically designed to minimize the risk of accidental ingestion of harmful substances.
Inhalation
Inhalation
It may go from the lymph to the bloodstream or penetrate blood vessels, directly allowing it a route to go elsewhere in the body.
they enter the bloodstream. when you get cut for example, the capillaries are broken, so there, the pathogens enter.
