The devastation caused by pollution can decrease through various measures both to prevent disease and improve environmental quality, which, without exaggeration, require the collaboration of the entire human society. And, as you can see, we are all more or less responsible and victims of this problem.

Among the most important to prevent illness are:

Follow a balanced diet, especially rich in fruits, vegetables and cereals, as these products contain vitamins and substances that strengthen the immune system (one that prevents diseases) while helping to eliminate toxic substances, such is the case of vitamins C and E.

The indoor life is not exempt from the action of contaminants such as solvents, pesticides, aerosols, water heater, stove, cigarette smoke, water and food with high levels of bacteria and noise generated by appliances, therefore, such seen, talking about the same problems mentioned above, only at lower levels, but also more direct action in individuals.

In 1990 a study by the Environmental Protection Agency (EPA, for its acronym in English) concluded that indoor air pollution is one of the most important environmental problems and requires more attention, primarily because the general population is not aware of its presence and danger. So many people use snuff or use too much insecticide and cleaners without realizing that this directly affects their health and that of those around them, perhaps to a greater extent than such notable acts as an oil spill or forest fire.

Noise pollution is due to noise generated by motors, tools, music and appliances, affecting those engaged in industrial or frequent busy streets, but also occurs in places that once were quieter, such as restaurants, gyms, cars and homes.

The intensity of different sounds is measured in decibels (dB), and is known to the human ear can perceive sounds well up to 120 dB, however, extended emissions in excess of 85dB can generate psychological disturbance and physical damage hearing, which besides being the organ of hearing directly involved in the balance.

Solid waste disposal, commonly known as garbage (food scraps, feces, plastic containers, glass, metals, paper, chemicals and debris), is now a serious ecological problem that scored highly dangerous to the environment and living things who live there.

The most common way to eliminate this waste, almost all of urban origin, is burying them in remote areas, but this focus has been achieved is the development of microorganisms that alter the balance of the environment and creatures that inhabit it. Also, these infectious agents and toxic substances can spread through the air or underground water flows, thus extending the pollution and its adverse effects to other areas.

Seas, rivers and other sources that supply the vital liquid to human populations have also been invaded by undesirable elements from drainage and waste from the same locality affected and nearby regions.

Among the main water pollutants are:

Household waste, animal manure and food waste.
Pesticides, plastics, detergents, industrial waste and oil.
Acids, salts and toxic metals.
Ash, sand, gravel and other solids from soil erosion.
Radioactive waste from nuclear power plants and medical treatment.
Bacteria, viruses, fungi and parasites.
Lilies, algae and other plants that prevent the circulation and oxygenation of lakes and rivers. Read the rest of this entry »

In recent years there has been an increase in the incidence of allergies (overreaction of the immune system to an allergen or stuff your body as harmful, such as dust, pollen or animal hair) in the respiratory tract such as rhinitis (itching nose, mouth, throat and eyes, sneezing, runny nose, headache, cough, fever) and asthma (inflammation of the bronchi that prevents proper breathing, manifested by cough and sometimes produces asphyxia).

This is due, according to experts, a combination of heredity and pollution, in particular, statistical studies show a direct relationship between increased environmental sulfur dioxide and the presence of these diseases in the bronchial tree.

The smog, also called smog, is the most famous air pollution, occurs when chemical compounds emitted by factory smokestacks and automobiles combine with moisture in the air. This type of steam as a mist is floating in the air and descends only through the rain, however, this fact and the combination of gas clouds resulting in acid rain that poisons lakes and animals that live in them, while damage to plants, disturbs the soil and harm the health of humans.

It is caused by toxic compounds such as lead, copper, zinc and oxides of carbon, sulfur and nitrogen that are thrown as a result of human activities and forest fires, mainly. Sources that emit air toxics can be fixed or mobile, the first, such as heaters, stoves, illegal burning of garbage, industrial and energy production plants are responsible for 20% to 30% of the pollution, while the second such as cars, public transport, trucks and aircraft cause the greatest amount of harmful gases (70% to 80%).

In the short term, the human body subjected to such pollutants manifest disease ravages through the skin, eyes and respiratory system, including:

Conjunctivitis. It is the inflammation of tissue covering the white of the eye and the inside of the eyelids (conjunctiva). Causing tearing and redness of the eye, mainly. Read the rest of this entry »

Technological advances and industrial generated from the second half of the nineteenth century have resulted in multiple benefits for humans, such as the emergence of modern methods of treating diseases, creation of satisfaction that facilitate productive activities and household, communication and transportation networks faster and more convenient food and clothing to personal needs.

However, these events have grown with a phenomenon whose impact is clearly negative for the survival of life on the planet: pollution or degradation of air, water and soil environment due to the presence or exaggerated increase harmful substances health. Read the rest of this entry »
