AB  - Plastic products are ubiquitous in our homes, but we know very little about 
      emissions from these products and their subsequent impact on indoor air quality. 
      This is the first study to systematically determine temperature-dependent 
      emissions of volatile organic compounds from commonly used plastic consumer 
      products found in the home. The plastic types included high-density polyethylene 
      (HDPE), polypropylene (PP), polyethylene terephthalate (PET), polystyrene (PS) 
      and polyester rubber. Plastic samples were exposed to increasing temperatures 
      (between 18 and 28  degrees C) in controlled environmental chambers, connected to a 
      proton-transfer-reaction time-of-flight mass-spectrometer (PTR-ToF-MS), where 
      real-time emissions were detected. Average emission rates were determined and 
      used to initialise an indoor air chemistry model (INCHEM-Py) at the highest and 
      lowest experimental temperatures, to explore the impact these product emissions 
      have on the indoor air chemistry. The PS tubing plastic proved to be the highest 
      emitting polymer per surface area. Almost all selected VOC emissions were found 
      to have a linear relationship with temperature. Upon observing the impacts of 
      primary VOC emissions from plastics in modelled simulations, the hydroxyl radical 
      concentration decreased by an average of 1.6 and 10 % relative to the baseline 
      (with no plastics included) at 18  degrees C and 28  degrees C respectively. On the other hand, 
      formaldehyde concentrations increased by 29 and 31.6 % relative to the baseline 
      conditions at 18  degrees C and 28  degrees C respectively. The presence of plastic products 
      indoors, therefore, has the potential to impact the indoor air quality.
