What a remarkable story! This method of removing lead from blood using magnets can eliminate up to 96% of lead ions in the blood.While lead poisoning has been in constant decline for some time, as recently as 1994, 4.4% of U.S. children aged 1 to 5 had  elevated lead levels. Incidences are much higher in developing countries. Deaths from lead poisoning in the U.S. are very rare now, less than 10 a year. However, the most concerning negative symptom of lead poisoning is impacted neurological function, learning disabilities, in some case, approaching brain damage. It's generally accepted that childhood lead exposure reduces IQ levels later in life. A peer-reviewed study from May, 2000 claims that lead exposure can explain 70-90% of variation in violent crime rates. A procedure to safely and effectively remove lead from blood could have huge repercussions, particularly in countries without strict protections and regulations.
