DESCRIPTION:Jeffrey Farner (Biocolloid Research Group\, Dept. of Chemical E
 ngineering)\n\nPatrick Julien (Friščić Research Group\, Dept. of Chemistry
 )\n\nWe are draining our planet to make plastic\, mainly for packaging. To
 day 8% of the world's annual petroleum production is converted into making
  plastics. Learn about plastic pollution in the environment today and the 
 future of bioplastics and other cleaner and more energy-efficient green ch
 emical synthesese.\n\nQ: If you burn plastics do they become nanoparticles
 ?\n\nA: Burning things does cause the formation of small particulates some
  of which are nanoparticles\, however these are generally different than t
 raditional plastic nanoparticles\, as they are either partially burned or 
 have transformed into carbon (also called soot) nanoparticles. These parti
 cles are also commonly observed from diesel exhaust\, and generally are a 
 product of incomplete combustion. While these soot particles are of consid
 erable health concern\, modern industrial incineration facilities are spec
 ifically designed and extremely effective at removing these contaminants a
 s well as other toxic or environmentally damaging emissions from burning p
 lastic waste. This is one of the reasons that burning plastic (in a fire p
 it) is considered particularly bad for your health and the environment\, b
 ut incineration can under the right circumstances be considered an environ
 mentally friendly solution.\n\nQ: What happens if you put the water flea b
 ack into a clean environment and get the nanoparticles expulsed over time?
 \n\nA: Daphnia have the ability to depurate\, or pass\, things they’ve con
 sumed but not been able to digest and use. As filter feeders\, most of wha
 t is consumed\, including plastics\, will be depurated over time. However\
 , some particles will make it through the digestive system and be retained
  within the body of the Daphnia. Those particles that are not depurated wi
 ll then me more likely to negatively affect the Daphnia. Additionally\, th
 e ability of certain compounds or particles to remain in Daphnia is the ba
 sis for trophic transfer\, in which species at lower positions of the food
  chain uptake a toxin\, are consumed by something higher on the food chain
 \, and then transfer that toxin to the higher species. In particularly con
 cerning cases\, this can lead to biomagnification where the higher species
  actually has a greater concentration of the toxin than whatever its food 
 source is. The ability of micro and nanoplastics to undergo trophic transf
 er has been observed\, and under which conditions this is most likely to o
 ccur is currently being investigated not only for Daphnia\, but many other
  aquatic and marine filter feeders such as mussels.\n\n\nRegistration\n\nT
