One instrument used extensively by every group to calculate concentration in parts per billion was the inductively-coupled plasma optical emission spectrometer. This instrument nebulizes a sample, and uses plasma to excite the electrons of specific elements. If you look at the ICP-OES on the screen you can see a little blue circle of plasma. Plasma is really cool, like 6000K cool! As the electrons return to their ground states, each releases a wavelength of light characteristic to its corresponding element. The optical emission spectrometer then measures the intensity of each element, which is converted to concentration by comparing the intensities to the known intensities of standard concentrations, as pictured above. Here, the calibration curve of Molybdenum is displayed on an intensity vs concentration graph. So if Molybdenum had an intensity of 120, the concentration would be about 150 parts per billion. http://www.dianliwenmi.com/postimg_11717122_18.html https://en.wikipedia.org/wiki/Inductively_coupled_plasma_atomic_emission_spectroscopy

The first experiment we conducted was the leaching of electronic parts in pond water. This allowed us to determine the concentrations of heavy metals leached from the e-waste. https://americanvision.org/7779/people-pay-big-money-to-be-told-theyre-evolved-pond-scum/

Efficacy of sand and soil to prevent leaching of heavy metals REMEDIATION Efficacy of sand and soil to prevent leaching of heavy metals http://theprepperproject.com/wp-content/uploads/2013/07/DirtBeforeAndAfter.jpg

STUDY: SAND AND SOIL AS RETENTION MEDIA 3 sand, 3 soil dishes 1 mL 27000 ppb lead nitrate Samples taken, analyzed for lead concentration

Sand retains lead better than soil Intensity plotted against radius Similar volume samples produced concordant results Soil carried a higher concentration of leachate further from contamination site

OUTLOOK Pond water: significant heavy metal leaching Crumb rubber: heavy metal leaching insignificant to human health Harmful volatile organic compounds Sand better at stopping leaching Potential use in e-waste facilities Pond water- significant leaching Crumb rubber- insignificant to human health. Volatile organic compounds? Sand was better at stopping leaching May be used in e-waste facilities
