Prevention of corrosion can be achieved through; appropriate storage, protective coating (painting/galvanization), greasing and oiling, alloying, and use of drying agents.
Causes of corrosion are; high humidity (and temperature), mechanical stress, acidic ambient media, uncoated and irregular metal surfaces, high conductivity and electrochemical potential.
Corrosion and rusting can be compared and contrasted based on their respective definitions, scopes, substrates, effects and prevention. Corrosion vs rust/rusting
Corrosion of metals is the outcome of reactions between metals and humid air, water or electrolyte, where the metals are transformed to oxides and hydroxides. Corrosion definition
Prevention of noise pollution can be achieved through; traffic infrastructural development, remote industrial installation, noise-control regulation, sustainable urban development, and use of good-quality sound systems.
Sources of noise pollution are; automobile vehicles and aircrafts, electrical speakers, industrial machines, large meetings and events, and natural features like volcanoes.
Examples of noise pollution are; occupational exposure to industrial blowers, highway traffic noise, regional disturbance from festive gatherings, short-term, narrow-range noise pollution by aircrafts, and acoustic disturbance from hailstorms.
Solutions to noise pollution are; acoustic barrier construction, afforestation, automobile maintenance and electric vehicle adoption, volume adjustment, and crowd control on highways, in neighborhoods and events.
Effects of noise pollution are; economic loss, biodiversity decline, and human health problems like; high blood-pressure, cardiovascular disease, and hearing loss.
