RUDN University
A group of medical and environmental researchers from RUDN University evaluated the level of heavy metals in the organism of first-year university students from different countries of the world. The results of the screening helped the scientists to reveal a relationship between a region of residence and the level of toxic metal in organism. According to their opinion, increased heavy metal levels in the organism of students from Africa and Latin America can have a negative impact on their health and performance. The results of the study were published in the Environmental Science and Pollution Research journal.
The group of heavy metals contains over 40 elements, the most poisonous of which are cadmium, lead, mercury, arsenic and nickel. The main source of heavy metals is industrial facilities: lead is used to produce batteries and electric cables, cadmium is an element of anti-corrosive coatings and electrodes, and semiconductor materials called arsenides are based on arsenic. Heavy metal compounds pollute water, soil, and air and from there get into the human body. RUDN medics and ecologists studied the concentration of heavy metals in the hair and urine of students from 48 countries and analyzed the effect of pollution on their health.
"The concentrations of heavy metals in human organism is an indicator of general pollution levels in respective regions.
