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.
But you can also use a flank steak if you have the tools and patience to pound it long and 1/2-inch thick. Each roll creates three one-inch pinwheels. To create more servings you can double this recipe and cook six pieces at the same time. Resist cutting the rolls thinner because the pinwheels will fall apart.
