Figure 1.

Figures 1A, 1B, and 1C are maps of Denmark depicting annual residential exposure levels. Figure 1A depicts uppercase l begin subscript den end subscript (decibel) exposure levels, ranging as 0.0 to 39.6, 39.7 to 444, 44.2 to 47.1, 47.2 to 49.9, 50.0 to 53.2, and 53.3 to 70.6. A scale depicting kilometers is ranging from 0 to 50 in increments of 25 and 50 to 100 in increments of 50. A scale depicting miles is ranging from 0 to 50 in increments of 25 and 50 to 100 in increments of 50. Figure 1B depicts particulate matter begin subscript 2.5 end subscript (microgram per cubic meter) exposure levels, ranging as 13.5 to 16.0, 16.1 to 16.9, 17.0 to 18.2, 18.3 to 19.7, 19.8 to 21.1, and 21.2 to 33.7. A scale depicting kilometers is ranging from 0 to 50 in increments of 25 and 50 to 100 in increments of 50. A scale depicting miles is ranging from 0 to 50 in increments of 25 and 50 to 100 in increments of 50. Figure 1C depicts nitrogen dioxide (microgram per cubic meter) exposure levels, ranging as 3.7 to 5.4, 5.5 to 6.4, 6.5 to 7.5, 7.6 to 8.7, 8.8 to 10.0, and 11.0 to 57.0. A scale depicting kilometers is ranging from 0 to 50 in increments of 25 and 50 to 100 in increments of 50. A scale depicting miles is ranging from 0 to 50 in increments of 25 and 50 to 100 in increments of 50.
