This document discusses the impacts of solid waste on health and the environment. It defines solid waste and describes its various characteristics. Solid waste comes from industrial, commercial, mining, agricultural, and community activities. Improper disposal of solid waste has negative impacts such as chemical poisoning from inhalation, increased flooding from obstructed runoff, and contamination of soil and groundwater through leaching. The accumulation of solid waste also affects animals, aquatic life, and contributes to issues like climate change and destruction of the ozone layer.

1. IMPACT OF SOLID WASTE ON
HEALTH AND THE
ENVIRONMENT

2. What is solid waste?
Solid waste is defined as any garbage, refuse,
sludge from waste treatment plant, water supply
treatment plant, or air pollution control facility and
other materials, including solid, liquid, semisolid,
contained gaseous resulting from industrials,
commercials, mining and agricultural operations
from community activities

3. What is solid waste?

4. Characteristics of wastes
Corrosive: these are wastes that include acids or
bases that are capable of corroding mental
containers, e.g. tanks
Ignitability: this is waste that can create fires
under certain condition, e.g. waste oils and
solvents
Reactive: these are unstable in nature, they cause
explosions, toxic fumes when heated.
Toxicity: waste which are harmful or fatal when
ingested or absorb.

5. Types of waste
Non Hazardous waste: refuse, garbage,
sludge, municipal trash.
Hazardous waste: solvents acid, heavy
metals, pesticides, and chemical sludges
Radioactive: high and low-level radioactive
waste
Mixed waste: Radioactive organic liquids,
radio active heavy metals. ”

6. Waste Treatment
Solidification Incineration
Waste
treatment
Heat
treatment
Chemical
treatment

7. Waste Disposal
Landfills: waste is placed into or onto the land in
disposal facilities.
Underground injection wells: waste are injected
under pressure into a steel and concrete-encased
shafts placed deep in the earth.
Waste piles: is accumulations of insoluble solid,
non flowing hazard waste. Piles serves as
temporary or final disposal.

8. Waste Disposal
Land treatment: is a process in which solid waste,
such as sludge from wastes is applied onto or
incorporated into the soil surface.
Waste are disposed in flowing rivers in less
developed countries.

9. Causal of Increase in Solid Waste
 Population growth
 Increase in industrials manufacturing
 Urbanization
 Modernization
 Modernization, technological advancement and
increase in global population created rising in
demand for food and other essentials. This has
resulted to rise in the amount of waste being
generated daily by each household. 158 million tons
of municipal solid waste is produced annually in U.S

10. Sources of Human Exposures
Exposures occurs through
Ingestion of contaminated water or food
Contact with disease vectors
Inhalation
Dermal

11. Points of contact
Soil adsorption, storage and biodegrading
Plant uptake
Ventilation
Runoff
Leaching
Insects, birds, rats, flies and animals
Direct dumping of untreated waste in seas, rivers
and lakes results in the plants and animals that
feed on it

12. Impacts of solid waste on health
 Chemical poisoning through chemical inhalation
 Uncollected waste can obstruct the storm water runoff
resulting in flood
 Low birth weight
 Cancer
 Congenital malformations
 Neurological disease
 Nausea and vomiting
 Increase in hospitalization of diabetic residents living near
hazard waste sites.
 Mercury toxicity from eating fish with high levels of
mercury.

13. Effects of Solid Waste on Animals and Aquatics life
Increase in mercury level in fish due to disposal of
mercury in the rivers.
Plastic found in oceans ingested by birds
Resulted in high algal population in rivers and sea.
Degrades water and soil quality

14. Impacts of solid waste on Environment
Waste breaks down in landfills to form methane, a
potent greenhouse gas
Change in climate and destruction of ozone layer
due to waste biodegradable
Littering, due to waste pollutions, illegal dumping,
Leaching: is a process by which solid waste enter
soil and ground water and contaminating them.
