18.1 Graph and Figure Interpretation Questions
Figure 18.1 Discarded electronic waste can leach heavy metals including lead. The light-coloured bar shows the percentage of electronic devices leaching. The U.S. EPA's regulatory threshold for lead leachate is 5 mg/L. The graph shows the percentage of devices that exceed the threshold, as well as the average concentration of lead leachate from each waste category.
Use Figure 18.1 to answer the following questions.
1) Refer to Figure 18.1. You want to reduce lead pollution from a landfill. The recycling of which computer equipment should be your priority?
A) computer mice
B) computer monitors
C) laptops
D) computer CPUs
E) VCRs
