New Study Reveals Ineffectiveness of Vehicle Exhaust Filters in Removing “Ultrafine” Pollution
A new study has revealed that vehicle exhaust filters may not be as effective in removing "ultrafine" pollution as previously thought. The study, conducted by researchers at the University of California, Riverside, found that while filters can remove larger particles from exhaust emissions, they are less effective at capturing ultrafine particles that are smaller than 100 nanometers in diameter.Ultrafine particles are a major concern for public health because they can penetrate deep into the lungs and even enter the bloodstream, causing a range of health problems including respiratory and cardiovascular
