The correct answer is 'C'. Coal-burning power plants are the primary source of atmospheric mercury.
Explicación
## Step 1The problem is asking us to identify the primary source of atmospheric mercury. The options provided are:A. Medical waste incineratorsB. Volatilization of lead-based paintC. Coal-burning power plantsD. Runoff from thermometer factoriesE. Municipal waste incinerators## Step 2We need to consider each option and determine which one is the most significant contributor to atmospheric mercury.## Step 3Medical waste incinerators, volatilization of lead-based paint, runoff from thermometer factories, and municipal waste incinerators do contribute to atmospheric mercury, but their contributions are relatively minor compared to coal-burning power plants.## Step 4Coal-burning power plants are a major source of atmospheric mercury because coal often contains trace amounts of mercury. When coal is burned, the mercury is released into the atmosphere.
