Your two adrenal glands are small, triangular-shaped endocrine glands located on the top of each kidney. Each adrenal gland is approximately 3 inches wide, and a half inch high. Each gland is divided into an outer cortex and an inner medulla. The cortex and medulla of the adrenal gland secrete different hormones.
The Causes of Ozone Depletion. Scientific evidence indicates that stratospheric ozone is being destroyed by a group of manufactured chemicals, containing chlorine and/or bromine. These chemicals are called ozone-depleting substances (ODS).
Ozone levels above a minimum concentration can cause pollution and harmful health effects. Ozone is created when volatile organic compounds (VOCs) react with oxygen in the atmosphere. The electrical energy in lightning can create ozone from oxygen molecules. The Earth's ozone layer was significantly reduced by CFCs, found in aerosol spray cans and other products.
