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.
A one inch thick steak will cook to a medium rare with one grill mark on each side, meaning the steak cooks for about 2-3 minutes on each side on a very hot grill. Give it one more grill mark on each side for about a minute and its medium. Just donât forget to turn the steaks 45 degrees to make nice grill marks.
