1.2 Calculate the Acidification Potential (i) Find the substance’s equivalency factor in Table 4.6. (ii) Calculate the acidification potential , EP(ac) by multiplying the magnitude of the emission (or the quantity of substance, Q) by the equivalency factor, EF(ac) (in Table 4.6) found: EP(ac) = Q x EF(ac) (4.7) Calculation of the equivalency factor for a substance is based on the number of hydrogen ions , which can theoretically be released from the substance directly or after any conversions in the environment. 1

Unformatted text preview: realised depends , as noted , on the accompanying anion release from the ecosystem which receives the emission . For some substances , the proportion of anions released can vary from ecosystem to ecosystem . • To reflect this, a site factor has been proposed, the value of which can vary between 0 and 1. 2 What Society Can Do About Acid Deposition • Understand acid deposition's causes and effects. • Clean up smokestacks and exhaust pipes. • Use alternative energy sources. • Restore a damaged environment. • Take action as individuals. 3...

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
