Architecture is both the process and the product of planning, designing, and constructing buildings or any other structures. Architectural works, in the material form of buildings, are often perceived as cultural symbols and as works of art. Historical civilizations are often identified with their surviving architectural achievements.
Architects and engineers are among the most fortunate of men since they build their own monuments with public consent, public approval and often public money.
Metals released into the atmosphere from human activities pose a significant risk to ecosystems and human health. Small airborne particles with a diameter of less than 10 microns can be inhaled and then absorbed into the alveolar tissue of the lungs, resulting in damage.
