HECA School Bus Filtration System Reduces Pollutants 88 Percent
An on-board air filtration system called high-efficiency cabin air, or HECA, developed specifically for school buses reduced exposure to vehicular pollutants by up to 88 percent, according to a new paper. study by researchers at the UCLA Fielding School of Public Health. The HECA system could help protect the 25 million American children who commute on school buses nearly every day, according to the authors from the UCLA Fielding School of Public Health. Children are more susceptible to air pollution than adults because they breathe more quickly and their immune and cardiovascular systems are still developing, said Yifang Zhu, the study's senior author and an associate professor in the department of environmental health sciences. read more
