Continued from page 19) other words there are many types of cleanup methods for the many types of contamination that might be found at a hazardous waste site. Current cleanup technologies aim to minimize the spread of contaminants during the cleanup process. It is an advantage to treat contaminants at the cleanup site as soon as they have been excavated, extracted, or pumped from the ground. This is because on-site cleanup combined with treatment reduces the need to haul hazardous materials to other locations.

In environmental science, the matter being measured is contamination, and each contaminant releases its energy as light. The light is then converted to a measurable color. Three types of spectroscopy carry out this conversion: scattering, emission, and absorption. Scattering spectroscopy measures the amount of light redirected by a substance. Emission spectroscopy measures light energy released from molecules (or atoms) when dropping from a high energy level to a lower energy level. Absorption methods detect a molecule’s energy change as it absorbs electromagnetic energy, which is electricity within a magnetic field.

They could do this only by analyzing their products and learning the exact composition of every batch they produced. In the early to mid-1900s scientists refined the techniques for studying elements and atoms rather than whole compounds. By doing this they gave birth to a new field called quantum chemistry. Max Planck made quantum chemistry’s first major discovery when he related wavelength to energy, yet his professors tossed aside his doctoral dissertation, partly because Planck’s theories had never before been proposed.
