CISCE: Class 10
Key Points: Concept of Waste
- Waste refers to materials that are no longer useful and are discarded by individuals, institutions or industries.
- Waste generation is natural and unavoidable—wherever there is life, waste is produced.
- Nature can decompose natural waste easily, such as animal waste, and recycle it back into the environment.
- Human-generated waste increases with development and is produced in large quantity and variety.
- Waste is of two types:
Biodegradable (organic, decomposes naturally)
Non-biodegradable (inorganic, does not decompose easily)
CISCE: Class 10
Key Points: Sources of Waste
- Domestic waste comes from homes and includes food waste, paper, plastics, glass, metals, ashes, sewage and discarded medicines.
- Industrial waste is produced by factories and includes chemicals, dyes, fly ash, toxic metals and industrial by-products, which may cause pollution.
- Agricultural waste includes crop residue, husk, straw, manure and vegetable waste; most of it is biodegradable and reused as manure or biogas.
- Commercial, construction and mining wastes come from shops, hospitals, building sites and mines, including packaging materials, bricks, debris and tailings.
- Special wastes include e-waste, biomedical waste and toxic waste, which are hazardous, difficult to recycle and harmful to human health and the environment if not managed properly.
CISCE: Class 10
Key Points: Impact of Accumulated Waste > Spoilage of Landscape
- Accumulation of waste in open areas spoils the natural beauty of the landscape and creates an ugly environment.
- Open garbage dumps become breeding grounds for mosquitoes, flies and rodents, spreading diseases.
- Toxic substances from waste may seep into the soil and pollute groundwater.
- Decomposing waste produces foul smell, causing discomfort to people living nearby.
- Indiscriminate waste dumping leads to pollution and health hazards due to population growth and the “use and throw” culture.
CISCE: Class 10
Key Points: Impact of Accumulated Waste > Pollution
- Meaning of Pollution
Pollution is the harmful change in the natural environment caused by human activities; substances causing it are called pollutants. - Main Types of Pollution
Pollution is mainly of four types: air, water, soil (land), and radioactive pollution, caused by industries, vehicles, waste, sewage, chemicals, etc. - Health Hazards of Pollutants
Toxic substances like lead, mercury, cadmium, nickel, asbestos damage the brain, lungs, kidneys, blood system and can even cause death. - Role of Waste and Human Activities
Accumulation of waste, burning of garbage, industrial effluents and chemicals pollute air, soil and water, spreading diseases and harming plants and animals. - CO₂ Increase and Global Warming
Excessive burning of fuels and deforestation have increased carbon dioxide, disturbing nature’s balance and leading to global warming.
CISCE: Class 10
Key Points: Types of Pollution
- Air Pollution
Air pollution is caused by gases like carbon monoxide, sulphur dioxide and hydrocarbons. It leads to respiratory diseases such as asthma, bronchitis and lung cancer. Smog and acid rain are major effects. - Acid Rain and Smog
Acid rain is formed when sulphur and nitrogen oxides mix with rainwater, damaging crops, buildings, soil and aquatic life. Smog (smoke + fog) reduces visibility and causes serious breathing problems. - Water Pollution
Water pollution is caused by sewage, industrial waste, agricultural runoff and mining. It spreads diseases like cholera, typhoid and jaundice and harms aquatic life. - Eutrophication and Thermal Pollution
Excess fertilisers cause eutrophication by reducing dissolved oxygen in water, killing aquatic organisms. Thermal pollution from hot industrial water also lowers oxygen levels in rivers and lakes. - Land Pollution and E-waste
Land pollution occurs due to accumulation of solid waste like plastics and electronic waste. Non-biodegradable materials pollute soil and pose long-term environmental hazards.
CISCE: Class 10
Key Points: Health Hazards
- Pollution and untreated waste seriously affect human health, causing respiratory diseases like asthma, bronchitis, and lung infections, especially due to air pollution and smog.
- Unattended waste becomes a breeding ground for disease-causing organisms. Flies, rats, mosquitoes and cockroaches spread diseases such as malaria, dengue and cholera.
- Water pollution from sewage, waste water and solid waste contaminates drinking water, leading to water-borne diseases like jaundice, typhoid and dysentery.
- Toxic substances in waste enter the food chain through biomagnification, increasing in concentration at higher levels and becoming harmful to humans (e.g. DDT, mercury, lead).
- Hazardous wastes like e-waste and biomedical waste release toxic chemicals and radiation, causing serious health problems such as cancer, nerve damage, brain disorders and epidemics if not properly managed.
CISCE: Class 10
Key Points: Effect on Terrestrial Life
- Effect on humans: Waste causes air and water pollution, spreads diseases (asthma, cholera, jaundice) and radioactive waste damages vital organs.
- Effect on plants: Toxic gases cause acid rain, dust blocks photosynthesis, and soil pollution harms roots and plant growth.
- Effect on animals & birds: Animals eat plastic and toxic waste, get injured, suffer diseases, reduced reproduction, or die.
- Effect on aquatic life: Waste, plastics, oil spills, hot water discharge and eutrophication kill fish and marine organisms.
- Biomagnification: Toxic substances increase along the food chain, finally harming humans the most.
CISCE: Class 10
Key Points: Need for Waste Management
- Waste accumulation is increasing rapidly due to population growth, industrialisation, urbanisation and the “use and throw” lifestyle, causing serious environmental damage.
- Waste pollutes land, water and air, leading to soil degradation, contamination of rivers and lakes, and overall imbalance in ecosystems.
- Accumulated waste spreads diseases as it becomes a breeding ground for vectors like flies, mosquitoes, rodents and stray animals.
- Water pollution from sewage, industrial waste, fertilisers and pesticides causes water-borne diseases such as cholera, typhoid, diarrhoea and hepatitis.
- Proper waste management is essential because continued pollution threatens ecosystem survival and human health, making waste control an urgent necessity.
