Which route of entry are chemicals absorbed into your body through your skin or eyes?
After inhalation from the atmosphere.
What is the difference between an injection that is given IM OR IV?
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.
How much sodium hydroxide will kill a person?
NaOH is not particularly toxic but it is extremely corrosive. Depending on the route of entry, a lethal exposure could range upwards from a few milliliters. A person would notice the exposure immediately and attempt to wash it off because of the pain associated with the tissue destruction.
What do you do with mercury?
Yes, if it is a small spill and you have the right supplies. Spills are considered small if there are less than 10 grams of mercury present (a pool about the size of a quarter). Thermometers, thermostats and light bulbs all contain less than 10 grams of mercury.What if it is a large spill?If the spill is larger than the size of a quarter, you should contain the spill (see the next question), then leave the area. Immediately call the local health department and a contractor who specializes in cleanup of toxic spills, as well as notify the property owner. It is a good idea to contact your State environmental agency for a list of contractors who cleanup toxic spills, so that you have phone numbers handy should you need them. If a spill occurs outside of regular business hours, call the local fire department. In cases where you spill one pound of mercury or more to the environment, you are legally required to report the spill to the National Response Center: (800) 424-8802. You should also contact your local Emergency Planning Committee. Find your local committee and write down its phone number now in case you need it later.A spill of one pound or more can occur if a container of mercury is spilled, or if mercury is spilled from a large device such as a manometer, flow meter, gas flow regulator, or industrial relay. Since mercury is very dense (more than 13 times as dense as water), one pound of mercury does not take up much space-approximately 34 milliliters or a little more than two tablespoons
What are the effects of ammonia on the systems of the body?
When ammonia enters the body as a result of breathing, swallowing or skin contact, it reacts with water to produce ammonium hydroxide. This chemical is very corrosive and damages cells in the body on contact.Symptoms of ammonia poisoningAmmonia is corrosive. The severity of health effects depends on the route of exposure, the dose and the duration of exposure. Exposure to high concentrations of ammonia in air causes immediate burning of the eyes, nose, throat and respiratory tract and can result in blindness, lung damage or death. Inhalation of lower concentrations can cause coughing, and nose and throat irritation. Swallowing ammonia can cause burns to the mouth, throat and stomach. Skin or eye contact with concentrated ammonia can also cause irritation and burns.
Why are medicines injected into the hypodermis?
"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
What route is nitroglycerin administered?
The route of administration of Nitrostat is sublingual
What is the most common and efficient route of exposure?
INHALATION
How is alcohol absorbed and metabolized?
The primary route is in the intestines. However, it is also absorbed in the mouth, throat and stomach.
Which route of exposure is not wide spread in industry?
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.
The most common route of exposure in industrial application is?
Inhalation
The most common route of exposure in industrial applications?
Inhalation
How does malignant melanoma progress from the original tumor to the bloodstream?
It may go from the lymph to the bloodstream or penetrate blood vessels, directly allowing it a route to go elsewhere in the body.
When pathogens enter your body through a cut what is the route?
they enter the bloodstream. when you get cut for example, the capillaries are broken, so there, the pathogens enter.

After inhalation from the atmosphere.
What route does tpn go through your body?
TPN is administered directly into the bloodstream, near the heart, and is pumped all over the body.
What can Mercury do to the environment?
The toxic effects of mercury depend on its chemical form and the route of exposure. Methylmercury [CH3Hg] is the most toxic form. It affects the immune system, alters genetic and enzyme systems, and damages the nervous system, including coordination and the senses of touch, taste, and sight. A significant problem is that mercury bioaccumulates. Each stage in the food chain (water insects --> minnows --> trout --> peole) receives a more concentrated dose which amplifies the effects.
