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.
The second side will take another five minutes to brown. The steak to the right was 1Â½ inches thick and needed 4 minutes more per side before it was medium rare. So, depending on how thick your steaks are, you may need to cook them longer. Use a digital thermometer to test the internal temperature of the steaks.
