Corrosive Acid

Everything found in the physical world around us is made of chemicals. The ground we walk on, the air we breathe, the food we eat, the cars we drive and the houses in which we live are all made of various chemicals. Living organisms such as plants, animals and humans are made of chemicals.

Some of the chemicals with which we interact in everyday life are anthropogenic. These drugs, cosmetics, chemicals in the workplace, the household cleaning products, etc.. Many other chemicals we are exposed daily are natural and we find them in our food, air and water. There are many more natural products than products in our human environment. The natural and anthropogenic chemicals can all have toxic effects.

There are various factors that may influence the degree of toxicity of a chemical. Here is a list:
Pathway in the body
Quantity or dose that enters the body
Toxicity of the chemical
Elimination from the body
Biological variation

To cause toxic effects, a chemical must first contact the organization.

It is mainly through breathing contaminated air that chemicals in the workplace enter the body. Some chemicals are able to penetrate through the skin when contact is made. In a less common, there may be ingestion of chemicals in the workplace if the food or cigarettes are contaminated. The eyes can also be a pathway. Generally, however, only very small quantities of chemicals enter through the mouth or eyes.

The amount or dose of a chemical that enters the body is probably the single most important factor for determining whether a chemical will cause poisoning. The amount that can cause poisoning depends on the chemical.

For example, what happens if a person drinks water during a hot summer day? Water cools the body and quenches thirst. Normally, we classify water as a harmless chemical. But what happens if, instead of a single glass, the person consumes a large number, one after another without stopping? It would reach a point where there would be more advantageous effects and where we would note adverse effects. Drinking too much water can cause water intoxication. In severe cases, this type of poisoning can cause seizures. Cases of this type of poisoning have been noted in young children and psychiatric patients. The reason water “change”, that is to say that it becomes harmful harmless, is directly related to the amount absorbed by the body. Drinking “too much” water causes intoxication. Absorb too much of a chemical that causes intoxication. This relationship holds for all chemicals, whether natural or anthropogenic.

Toxicity is a measure of the ability of a chemical poisoning. Chemicals that are only slightly toxic to be absorbed in large doses to cause poisoning. Small doses of highly toxic chemicals are sufficient to cause poisoning.

Toxicologists often perform tests on animals to determine whether small or large doses of a specific chemical cause toxicity. One such test measures the amount of chemical required to cause death in 50% of animals. This dose is called “lethal dose 50 (LD 50).

We tend to think in terms of chemicals and toxins harmless. It is convenient to use these categories, but they imply that toxicity, or lack thereof, is owned by “all or nothing” of the chemical. This is not the case, since all the chemicals can cause poisoning if the dose is sufficient. Nature's gift not paid the Indian tea is a delight of corp

In other words, all chemicals can be toxic. This is the amount or dose absorbed by the body that determines whether or not there will toxic effects. Intoxication is not only caused by exposure to a specific chemical, but rather by exposure to excessive amounts of this product.

Many chemicals in the workplace enter the body and are unchanged when they are eliminated. Others deteriorate. Degradation products may be more toxic or less toxic than the chemical origin. Other chemicals are stored temporarily in the organs and are removed shortly after. Finally, most chemicals and their breakdown products are excreted in feces, urine, sweat and expired air. Some chemicals, such as silica dust or graphite, may be inhaled, lodge in the lungs and remain there for many years. They may never be completely eliminated.

In general, the risk of disease caused by a chemical is lower if the body is able to do one or two things:
degrade the chemicals into less toxic
quickly eliminate the chemical from the body.
