Question- As a well respected analytical chemist, a local environmental group wishes to consult you on an appropriate atomic spectrometric technique to use in a two year project that will be monitoring the water quality in lake. The analysis needs to include Pb, Cd, S, Cu, and Hg with up to 5 samples being collected every 2 weeks.
Discuss what technique you would recommend and what advantages it may have over other, similar techniques. Provide a brief explanation of the potential problem you may encounter with your recommended analysis technique and how you may minimize them?
Please define why you think that's the right answer
