Pollution and toxic waste are a poorly understood aspect of progress. Human beings do not realize the magnitude of the problem. Live every day with thousands of chemicals that reach him through the water, air, land and the products they consume. Currently, there are between 80,000 and 120,000 synthetic chemicals in production and released into the market an average of 3 new synthetic chemicals per day. There is very little information about many of these compounds and their impact on the environment and health of people.
The emission to the environment of these substances pose a serious risk to life. Every newborn has on your body and contaminants in the environment by human activity. The continuing contamination, daily quiet is much more severe than occasionally splashing the pages of newspapers. Accidents Valdex-Exxon supertankers, Aegean Sea, Prestige …-, of industrial-plant biocide of multinational Union Carbide in Bhopal, India, remain small when compared with the amounts of pollutants are discharged annually worldwide.Carbon dioxide, CO2, nitrogen oxides, hydrogen chloride, sulfur dioxide, heavy metals … multitude of substances that arise from activities such as petroleum refining, steel, generation of thermal electricity, cement and related factories pulp, paper and cardboard, automotive and chemical industries, etc..
Each substance in a certain way affects humans. Many do not degrade, but persist and accumulate in the body. Eye irritation and other sensitive tissues, respiratory problems, damage to the neurological system, the immune system, heart and kidneys, even in the mental development of children come to be common, as well as tumors and cancer.
Hundreds of thousands of petrochemical and energy, oil drilling, refineries, power plants, chemical and chlorine plants are located near the sea and use it as a toxic waste dump. The paper industry alone is responsible for the annual discharge of billions of tons of waste.
For years it has tried to introduce in less developed countries polluting technologies, such as incinerators, rejected in developed countries. Due to its effects on health and public pressure, since the mid 90′s these technologies began to be replaced with more clean in countries like the United States. Companies that manufacture incinerators, rejected in their countries of origin, then began to seek markets in the south, in underdeveloped countries, especially in Africa, where health and environmental standards are lax.
The amount of hazardous waste produced by mankind amounts to billions of tonnes of residues from the manufacture of solvents, synthetic paints, coatings, biocides and paper is a qualitatively much more dangerous than the billions of tons of sulfur dioxide, which receives the atmosphere per year, much that is primarily responsible for acid rain. Toxic wastes retain their lethality even in tiny doses over decades.
The origin of the “special” waste and emissions of toxic substances is none other than the use of toxic raw materials and processes in industrial production. Until very recently, the waste is deposited, without more, in landfills, rivers, seas or anywhere else that was nearby. In agricultural and pastoral societies is very little waste produced unusable. With industrialization and development have increased the number and variety of waste generated. For several decades have followed the simple system eliminating the spill. This was done even with the increasing amount of toxic chemicals that are produced. But it has gradually become clear, over time, the serious implications for the hygiene and health of people and the significant negative environmental impacts of this system of waste disposal.
The problem is aggravated by the growing industrial activity produces many products that are toxic or very difficult to incorporate into the cycles of natural elements. On several occasions the chemicals accumulated in landfills, which have since been covered with earth and used to build houses on them, have caused serious problems, including damaging the health of people.
These wastes, as they are always linked to toxic industrial production systems, cause many other risks and pollution problems such as pollution and hazardous exposure of workers. Millions of workers die of cancer from exposure to carcinogens in the workplace. The population exposure to waste is caused by air emissions, spills, leaks, leaks, accidents often occur as in factories and in transport. The toxic substances used by industries are also incorporated to consumer goods and building materials.
