Duckweed and Arsenic Growth Bioassay

The purpose of the Duckweed growth bioassay is to investigate the effect of varying arsenic concentrations in water on the growth rate of plant life. This slideshow will give a walkthrough of the preparation of a sample based in a 50 ppb arsenic solution. The full protocol uses triplicates of samples based in 0, 50, and 100 ppb arsenic solutions. The samples should be left to sit for a few days, with regular monitoring and re-counting of the duckweed leaves to track change.
