Study Notes
Environmental Health and Industrial Impact
- Human activities are the primary cause of adverse environmental conditions.
- Britain, the first country to industrialize, faced significant health impacts from a deteriorating environment in the 19th century.
- Working-class slums featured overcrowded, unsanitary living conditions, with inadequate water and sewage systems, leading to health crises.
- Edwin Chadwick's 1842 report linked unsanitary conditions and overcrowding to disease, advocating for centralized health governance.
Health Reform and Legislation
- Chadwick's findings spurred government initiatives and mobilized reformers, including women pursuing sanitary reforms as part of municipal housekeeping.
- City health offices were established in the U.S. and local health boards in Britain, focusing on solid waste, water quality, sewage disposal, and housing regulations via the public health ordinance.
- In Nigeria, organizations like NAFDAC and FEPA regulate environmental health issues, aiming for compliance with international standards.
Modern Environmental Challenges
- Industrialization has introduced new health concerns, including noise pollution, air quality, toxic substance control, and pesticide regulation.
- The Federal Environmental Protection Agency (FEPA) in Nigeria was created in 1988, later succeeded by the Ministry of Environment in 1999 to address these modern challenges.
- Legislation attempts to balance environmental health with industrial growth and employment.
Importance of Water Supply
- Safe domestic water supply is vital for human survival and overall health.
- Water-related diseases are responsible for approximately 5.8% of deaths in high-mortality developing countries like Nigeria, highlighting the critical need for safe water access.
- International conventions, such as the UN's International Drinking Water Supply and Sanitation Decade and Millennium Development Goals, aim to ensure universal access to safe water.
Water Quality Assessment
- Identifying community water supply sources is essential; groundwater may contain harmful elements like excessive iron, manganese, and fluoride.
- Effective water interventions must meet per capita needs and ensure high-quality water from source to use.
Water Purification Methods
- Rainwater can be a viable drinking water source if impurities from collection systems are mitigated.
- Various purification techniques include:
- Coagulation and Flocculation: Coagulants help suspend solids form settleable flocs.
- Secondary Sedimentation: Larger flocs settle out over time.
- Rapid Sand Filtration: Water passes under pressure through a sand filter to remove impurities.
- Aeration: Enhances water taste and odor by transferring oxygen.
- Disinfection: Removes microorganisms using methods like UV irradiation or chemical agents (e.g., chlorine), which also provide residual protection against recontamination.
