Study Notes
- Recyclable material is solid waste that is processed and returned to the economic mainstream.
- Hazardous waste is dangerous or potentially harmful to human health and the environment.
- Types of sanitation include: basic, on-site, food, environmental, and ecological sanitation.
- Environmental health administration is responsible for directing environmental and food sanitation programs.
- Housing and indoor environment significantly impact physical, mental, and social health.
- Unsafe housing can cause injuries and health threats due to poor air quality, temperature, hazardous substances, and sanitation.
- Substandard housing may lack adequate sanitation, clean water, heating or cooling, and be structurally unsound.
- Access to safe water is essential for health and socio-economic development.
- Water can be contaminated naturally or through human activities, leading to health risks.
- Biological harms of water include infections from viruses, bacteria, protozoa, and helminthes.
- Chemical harms include contamination from detergents, solvents, cyanides, heavy metals, nitrogenous substances, and bleaching agents.
- Water can be purified through boiling, storage, chemical disinfection, filtration, ozone gas, ultraviolet radiation, or reverse osmosis.
- Disinfectants used in water supplies should effectively destroy pathogens without leaving toxic byproducts.
- Parameters in drinking water include physical parameters (color, taste, odor, turbidity, pH, TDS) and chemical substances (barium, fluoride, lead, mercury, nitrate, nitrite, selenium).
