Industrial and miners are a problem in different points of our geography. It is still a problem in places where deindustrialization left hectares of empty but contaminated soils and is a problem in the vicinity of some active industrial poles. And one of the places where this is most appreciated is in the estuary of the Odiel and Tinto rivers, on the coast of the province of Huelva.
As, PB, CD, MO, SE. A new study He has found evidence that people who live in the vicinity of Huelva industrial areas accumulate in their bodies amounts higher than the average heavy metals such as those we usually associate with industrial activity.
The study observed that among the inhabitants of the region, the accumulation in the body of certain elements was greater than usual. The study was done In the city of Huelvabut it was observed that the pollutants varied depending on the residence area of the participants.
Different concentrations. Among those who lived in areas closer to the rafts of phosphoyesos From the region, the study found a greater presence of elements such as arsenic (as), lead (PB), cadmium (CD), molybdenum (mo) and selenium (se). These types of elements can be found, precisely in places where this type of waste is stored.
On the other hand, the team also found areas that stood out for the presence of elements such as copper (cu), zinc (zn) and aluminum (al). These areas were the closest to the industrial area of the region.
In general, the inhabitants of the city of Huelva presented greater concentrations of iron (faith), nickel (ni), chromium (cr), selenium (se), arsenic (as), and copper (co) according to the results of the study.
The “chemical and industrial pole. The study was conducted in the city of Huelva, a city located near the coast, between the confluence of the red and odiel rivers. The city counts around, explains the team responsible for the study, with three important industrial areas.
First, phosphoyesos rafts can be found, an industrial residue resulting from the extraction and processing of phosphoric acid. This residue is categorized as a radioactive material that occurred naturally or norm (Naturally Occurring Radioactive Material) and the Huelva reserve is the largest in Europe, the team recalls.
To this we must add two more conventional industrial areas, the “Chemical Pole for the Promotion and Development of Huelva – Punta del Sebo” and the “Nuevo Puerto Palos de la Frontera”. Both areas also located in the vicinity of the capital (being the first adjacent to it).
55 participants. The study was conducted with a little girl from participants residing in the capital. Samples extracted from the feet nails of these to estimate the concentration in the bodies of a series of elements: aluminum (al), arsenic (as), cadmium (CD), copper (cu), chrome (cr), iron (faith), nickel (ni), Uranium (U), Vanadio (V) and Zinc (Zn), among others.
The details of the study were published In an article In the magazine Journal of Xenobiotics.
