Study Notes
Environmental Health Overview
- Environment encompasses all external influences and conditions affecting life and development, including humans.
- Ecology studies interactions between organisms and their nonliving environment, including energy and matter sources like sunlight, air, water, and soil.
Categories of Environment
- Natural Environment: Comprises soil, air, and water.
- Man-made Environment: Includes food, homes, medical care, and hospitals.
Forms of Environmental Components
- Biotic Environment: Consists of living organisms such as humans, plants, animals, and microorganisms.
- Abiotic Environment: Encompasses non-living elements like water, air, and other physical resources.
Health and Environment Relationship
- Health is a state of dynamic equilibrium between humans and their environment.
- Disturbances in this equilibrium can lead to ill-health or disease.
Three Components of Environment
- Physical Environment: Includes water, air, soil, housing, radiation, light, noise, vibration, refuse, and waste.
- Biological Environment: Comprises plants, animals, rodents, insects, and microbes like bacteria, viruses, rickettsiae, parasites, and fungi.
- Social Environment: Involves customs, culture, habits, income, occupation, and religion.
Impact of Environmental Factors on Health
- A significant portion of human health issues is linked to environmental factors.
- Adverse conditions like water, soil, and air pollution, along with poor housing and presence of disease vectors (animal reservoirs and insects), contribute to health risks.
