Metal contamination

 In blog

You can naturally find dissolved metals in water, as well as other types of metals used by man and the use of various metals has marked the advance of civilizations over the years. Since the beginnings of civilizations, man has developed materials that he uses to make weapons, tools and various tools to survive; in prehistory men used materials made of stones such as quartz and obsidian to make different artifacts reached a great cultural development.

Later, the Bronze Age began where metals began to be used daily for utensils. More than 7000 years ago humans already manufactured with copper, they knew how to extract and use it.

Heavy metals such as mercury, plumb, cadmium, thallium, zinc, chromium and bronze are the ones that produce the most contamination; although aluminum, beryllium and arsenic (semi metal) also produce pollution and there are places that due to the large number of the last three become deadly.

Heavy metals cannot be degraded and they are able to accumulate in living beings, food and nature. In humans, metals are capable of causing chronic pain, blood problems and even psychic problems that can seriously affect humans. After the copper age, the Iron Age began because iron was more abundant and easier to create different objects. From the beginning of the writing the end of the Iron Age is determined. However, the use and investigation of various metals, their properties and how to create more resistant and better quality materials continues until our days.

As we already mentioned, metals are present in the earth; and some of the metals are essential for the functioning of the human body, the problem begins when in the body there are higher concentrations can cause poisoning and even death. Metal contamination can be in air, water or soil. In the air they occur when they are close to where they are emitted; but in the water it can go further, if a river is polluted, it will also contaminate the soil and the living beings that inhabit it, producing a change in the food chain. In addition, it can pollute groundwater, accumulating in plants and other living things.

When these metals begin to accumulate in living beings, it can affect the food chain since when one contaminated animal is consumed by another one; the accumulation of metals increase. From the time of the Romans they could already diagnose symptoms of plumb poisoning. In addition, exposure to metal contamination can lead to poisoning, developmental delays, cancer, damage to the kidney and various psychological problems such as anxiety.

Metal contamination has increased considerably due to the growth in industrial and mineral activity that, when in operation, emits contamination such as lead, mercury, arsenic and others that are very harmful to health.

Due to the large amount of pollution, different agreements have been created that aim to reduce emissions of different pollutants. The first was the Geneva Convention where hundreds of countries met to commit themselves and create actions to reduce CO2 emissions. As of this agreement, more protocols and agreements have begun to be created. An example is the Aarhus protocol dealing with the long-range transboundary contamination of metals.

One of the biggest pollutants is the combustion of gasoline that produces plumb and this gas stays suspended in the air of the cities, affecting the quality of the air we breathe. Traffic in large cities is one of the problems of today’s society due to the large number of vehicles that exist, and each of them has four tires which produces even more pollution; tires normally have a life of five years (average), and when discarded, abandoned tires emit a large amount of gases in the environment; for this reason it is very important to recycle them. There are many products that can be made from recycled tires, some of them are:

– Derived fuel. This type of product is useful for industries such as cement, paper and energy. This is because the tires have large heat properties so they produce more energy than coal, wood or other materials.

– Derived aggregate. This product is used in civil engineering projects, filing the ground in constructions and every day is investigated other uses for recycling tires in order to have a greater impact.

– Colorized rubber mulch. The raw rubber mulch is used for landscaping to improve gardens or sidewalks; we offer also rubber mulch painted in different colors to improve the view.

– Colorized buffings. It has the same uses as the rubber mulch, but we cut the material in a different way.

– Colorized crumb rubber. It is rubber granulate, but we paint it in order to install it in playgrounds for recreational areas or schools.

– Granulate. This product is smaller than the rubber granulate without the painting, normally this is the base of playgrounds without any color, or for other products.

– Infill material. It is larger size of rubber granulate, and this is applied in the sport fields that uses artificial turf, is a different process from the other granules.

The rubber granulate is used for the creation of many products like courts and even shoes. We are committed to reducing the pollution of the environment; if you have questions about our products or for more information about this service call us (001) 760 599 3841 or send an email to and we will gladly assist you.
