Summary
[edit]DescriptionFatbag Membrane (4817490393).jpg |
Although oil and water do not normally mix, oil contaminants in waterways can be measured using a special membrane nicknamed a "fatbag." The fatbags absorb many fat-soluble chemicals from the water at a known rate, so they can be used to estimate the concentration of such chemicals.
