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.
Take a look at how thick your steaks are. The thickness is one of the deciding factors of cooking time. Common measurements are 3/4 inch, one inch, one and a half inch and two inches thick. Grill thicker steaks on a lower temperature; the thicker the steak, the lower the heat you'll use.
