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.
3) Flank steak is usually wedge shaped. One end is a lot thicker than the other. When you cook it hot and fast one side is either overcooked or undercooked. So here's how to outsmart the steak. If your steak is more than 1/4 thicker at one end than the other, cut it in half and start the thick half first.
