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).
Secondary pollutants include: 1  Particulates created from gaseous primary pollutants and compounds in photochemical smog. Smog is a kind of air pollution. 2  Ground level ozone (O3) formed from NOx and VOCs. Ozone (O3) is a key constituent of the troposphere. 3  Peroxyacetyl nitrate (C2H3NO5) - similarly formed from NOx and VOCs.
