When a substance has harmful or dangerous properties, it is a toxic substance and its potential capacity is its toxicity. Consequently, the toxicity of something (for example, of a specific metal) establishes that its properties have a certain danger, such as for the health of people, for the development of a plant or for the life of animals.
Toxic methods for human health
Metals such as mercury, lead, aluminum, nickel or arsenic have a certain degree of toxicity and gradually affect our body. We are exposed to these metals and each one of them is potentially harmful to health. Toxicity
Mercury is found in silver fillings used in dentistry or in tattoos and its accumulation can affect the brain , kidneys or liver, in addition to causing immune disorders or memory loss. Lead is found in newspapers, in canned foods, in some cosmetics, toothpastes and insecticides. The exposure to this metal adversely affects the brain or liver.
Aluminum is found in water services to eliminate waste, in pots and pans. And when it comes into contact with the bloodstream, it becomes a toxic element that can cause cerebrovascular accidents, anemia or memory problems.
Nickel is found in stainless steel utensils for home use, as well as coins. Its accumulation in the body is one of the causes of cancer and certain skin diseases. Toxicity
Arsenic is found in cigarette smoke, detergents, some beers and shellfish. Its accumulation is in the kidneys or liver and can cause headaches, fatigue and mental confusion.
the toxicity of alcohol
Alcoholic beverages contain ethyl alcohol, a substance with high toxicity. In fact, alcohol dependence is very harmful to our body. The list of harmful effects is quite extensive: hypertension, vitamin deficiency , seizures, anemia, respiratory problems, sleep disorders, gastric disorders, muscle weakness, among others.
Toxicity is the discipline that studies the harmful effects of some substances
Toxicity is a discipline with numerous links in other areas, as it is related to legal medicine, pharmacology and criminal medicine .
Toxicology specialists study the adverse effects of xenobiotics, that is, substances that negatively affect the development of life in general. The xenobiotic is, therefore, any component that endangers health due to its polluting and degraded capacity.
