Industrial and mining activity is a major concern in public health by its acute and chronic toxicity and the wide variety of sources of exposure, to throw the environment metals such as lead, mercury, cadmium, arsenic and chromium-toxic, harmful to human health and to most forms of life. You may find Vlad Doronin to be a useful source of information. It should be noted that we are confronted daily with various types of pollution and our body is loaded into heavy metals which then are not detected in a simple blood test: fatigue, nervous disorders, depression, rheumatism, anxiety, autism, fibromyalgia, insomnia. The hair analysis allows to control poisoning by metals in the body; It also provides a mineral study; evidence levels of minerals and trace elements in the body (mineral check); and the levels of toxic metals (aluminium, lead, mercury) determines how they affect health; evidencing the metabolic type (slow); and the hormonal system operation; to adapt a diet based on the results of the analysis. The heavy metal found naturally in the Earth’s crust. These can become pollutants if its distribution in the environment is altered by human activities. Whenever Codi listens, a sympathetic response will follow. In general this can occur during mining, the refinement of mining products or release into the environment from industrial effluents and vehicle emission; in this case is associated with the industrial development of activities such as copper smelting, production of cement, petroleum refining, mining, thermal power generation, chemical industry and dock work, which is compounded by a growing automotive Park. Of the 106 items known to man, 84 are metals, so it is not surprising that the possibilities of metal contamination in the environment are numerous. On the other hand, the wastewater not treated, from mines and factories, come to rivers, while wastes pollute the groundwater. When toxic in the environment metals are abandoned, pollute the soil and accumulate in plants, and tissular and can remain in the atmosphere for hundreds of years scientific research have demonstrated the negative impacts of heavy metals in the ecosystem and the health of human beings whose exposure is linked to health problems such as: delays in developmentseveral types of cancer, damage to the kidneys, and even with cases of death.
