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.
Coat the grill grate or pan with olive oil, and place the steak on the cooking surface. Allow it to cook for no more than 4-6 minutes on each side, for a total of 16-24 minutes. Flank steak is too thick to be cooked well-done. The end result should be medium-rare.
