Answer the following statement true (T) or false (F)
True
Air pollution control devices (when installed) are effective at reducing emissions of mercury and toxic metals at coal burning power plants. Instead of becoming air pollutants, they become solid toxic waste that must be properly stored to avoid soil and water contamination. The problem is that it is usually buried in a toxic waste landfill and expected to remain isolated from the environment forever.
