Effects of Photochemical Smog. Photochemical smog's effects cause damage to the respiratory system and environmental systems with the release of nitrogen oxide (NO), ozone and volatile organic compounds (VOCs). These effects are worse when the sun is highest because the pollutants react with it.
This cut is called a flank steak because it literally comes from the flank of the cow â its side, below the ribs. It's a fairly wide and thin cut; it's only 1 to 1 1/2 inches at its thickest and it becomes even thinner toward one end.
Step 2: Measure the steaks' thickness. One-inch-thick steaks are ideal for broiling. If your steaks are slightly thicker or thinner, you will need to adjust the cooking time accordingly (longer for thicker steaks, shorter for thinner steaks).
