10% although according to Miller LITE, it can range anywhere from 2-40%

Yes!

Go ahead.

What are the RCRA-8 metals?

RCRA 8 includes arsenic, cadmium, barium, lead, mercury, chromium, selenium, and silver.

Next question: why are environmental scientists particularly concerned about the presence of aerosols in the troposphere today? (There may be multiple answers, so feel free to take a guess!)

The troposphere is where clouds and other weather phenomena form. As aerosols increase in the troposphere, act as condensation nuclei meaning that water and the aerosol form a solution. When the solution precipitates out, the aerosol is deposited and since aerosols can sometimes be toxic, they are harmful to life. Also they can cloud out the sun leading to a cooling of the earth. Some aerosols can act as a greenhouse gas as well leading to climatic catastrophe (much like the cooling and warming during/after the K-T Extinction Event)

Thanks! Um let's see....What is the main cause of currents?

Most surface currents are caused by the wind; this can include input from the Coriolis force, general wind patterns, and also landforms above sea level and on the sea floor. Deepwater currents are formed when surface winds drive currents along with upwelling and landforms. 
Also, another current source: density changes caused by differences in salinity and/or temperature. This is what drives most upwelling currents in the sea, caused by convection (driven by geothermal heat from the Earth's core).
