HoK Hosts Pollution Seminar

On Dec. 7Th, House of Knowledge International Kindergarten (HoK) was pleased to host the first of a six part series of free information seminars at their Chaoyang Campus. This first event was a workshop for those seeking information about living with pollution.

Dr. William Chickering, pollution researcher and ER doctor at Beijing United, began talks by sharing results of his own research as well as those of international studies on pollution. While he admitted the long term and irreversible effects of pollution had been found to be relatively lower than most would expect, he encouraged those living in big cities to avoid spending time near large freeways where fuel emissions, and thus health risks, consistently test at higher levels.

Air specialist Chris Buckley, from the Torana Clean Air Center, continued discussions by showing attendees how air filters work, and by answering questions on how to reduce pollution levels in the home. Most were surprised to hear that humidifiers that spray mist into the air (such as those commonly seen in homes and on office desks in Beijing) drastically increase dust content in areas where they are used. Buckley explained that calcium and magnesium deposits in local tap water are made airborne with this mist, and these free-floating particles greatly contribute to dust problems. As an alternative to this popular style of humidifier, he suggested using models that use passive evaporation (instead of mist) so that the heavier particles are not made airborne, but instead, remain within the devices. While he conceded that these types of machines need more cleaning, the cleaning your lungs require to rid themselves of dust particles becomes noticeably less.

HoK’s next free seminar is on Multilingualism in Early Childhood and takes place at House of Knowledge’s Chaoyang Campus on January 25th at 7:00pm.
