 Groups of 4-5  Each person gets 1-2 minutes  Choose the best one to share with the class!

 What do you think is lurking in your house?  Sometimes it is much more sinister…  ator ator  made-flooring-sold-by-lumber-liquidators- releases-harmful-levels-of-formaldehyde/ made-flooring-sold-by-lumber-liquidators- releases-harmful-levels-of-formaldehyde/  /how-a-math-blunder-reignited- doubts-about-lumber-liquidators /how-a-math-blunder-reignited- doubts-about-lumber-liquidators

 Smoking!!  Carbon Dioxide  Carbon Monoxide  Particulates Matter  Heavy Metal Particulates – Arsenic, Cadmium,  Radon  VOCs from new building products

 Developing countries- particulate and Carbon Monoxide more likely (burning fuel indoors for warmth)

 Increased energy efficiency of buildings  Seal windows  Caulk cracks  Use lots of insulation  Means that air filtration and ventilation systems really need to work  Dirty filters  Mold growing on filters  Poor design  Old

 You spend majority of time inside  There are lots of chemicals inside of buildings  Inside often not as well ventilated  Concentrations of indoor pollutants are often much greater that outdoors

 Several people who live or work in the same building are experiencing a variety of immediate ailments (usually headaches, nausea, burning eyes)

 Usually in newer buildings, as carpeting, cabinets, etc. give off VOCs like formaldehyde  EPA causes:  Inadequate or faulty ventilation  Indoor contamination from building materials  Outdoor contamination entering in through ventilation system  Biological contamination (i.e. mold)

 People who work in industries that produce high levels of particulate matter suffer lung damage  Black lung disease often affects coal miners

 Your group will make an informative presentation for one assigned indoor air pollutant: Radon VOC’s Carbon Monoxide Asbestos Mold/Pollen

 What is your pollutant, chemically or biologically?  Major sources  Major health consequences  Where it is an issue  EPA or WHO acceptable levels  How to reduce levels of the pollutant 5 minutes! Can be a short PowerPoint or poster You will present at the beginning of next class!
