- Adverse Effects of Chemistry
Chemical products have negative or adverse effects on our daily life
The Adverse Effects of Chemistry include;
1. Drug Abuse: Many drugs like cocaine, morphine, heroin, etc; when abused (wrongly used) can cause damage to the body.
2. Pollution: One of the main adverse effects of chemical industries is the pollution of the environment by:
- Chemical wastes from chemical and petrochemical industries.
- Crude oil spillage, exhaust from motor vehicles.
- Plastic containers – They are not biodegradable (not decomposed by bacteria) thereby causing soil pollution.
3. Corrosion
Corrosion is defined as a natural process that causes the transformation of pure metals into undesirable substances when they react with substances like water or air. This reaction causes damage and... More: Corrosion or rusting of iron occurs when the iron is exposed to water or oxygen. When iron or steel is exposed to the atmosphere, they rust. These objects can either be protected or replaced.
Many countries have imposed strict laws to control pollution and drug abuse.
