    Study Notes

    Environmental Health

    • Environmental health is the relationship between human health and the environment.
    • It aims to improve human health now and in the future by protecting, restoring, and improving environmental quality.
    • Key environmental factors affecting health include:
      • Biological: Microbial pathogens
      • Chemical: Tobacco, pesticides, heavy metals
      • Physical: Noise, radiation, homelessness
      • Accidental: Natural disasters, road traffic accidents, climate change
    • The global burden of environmental disease is significant, with 24% of adults and 26% of children dying from environmental causes.
    • This burden is disproportionately experienced in low- and middle-income countries.

    Water, Sanitation, and Hygiene (WASH)

    • Access to safe water is not universal, with 3.5 billion people lacking access to safe sanitation and 2.2 billion lacking access to safe water in 2022.
    • Half of the world experienced water scarcity in 2022.
    • In Bahrain, water sources include desalination (10%), groundwater (36%), and treated wastewater (54%).
    • Water treatment involves coagulation, flocculation, sedimentation, filtration, and disinfection (chlorine).
    • Fluoridation is the controlled addition of fluoride to public water supplies where natural levels are insufficient.
    • Fluoridation is one of the most effective public health interventions to prevent tooth decay, but it is controversial due to research quality concerns and potential side effects of excessive fluoride.
    • Bahrain's groundwater has fluoride concentrations within the WHO recommended level, and water fluoridation is not currently practiced.

    Health Impacts of Unsafe Water

    • Unsafe water contamination leads to various health problems:
      • Growth of disease vectors in the water
      • Heavy metals poisoning
      • Sewage contamination, leading to infections like cholera, giardiasis, shigellosis, typhoid, E. coli, and campylobacter.
      • Helminthiasis
      • Drownings and related injuries

    Solutions to Water Contamination

    • Monitoring water supply through microbiological, chemical, and physical analysis helps ensure safety.
      • Microbiological analysis includes checking for indicator organisms like fecal coliforms and E. coli.
      • Chemical analysis identifies chemical and metallic contamination like lead, mercury, arsenic, iron, and pesticides, as well as sewage contamination (ammonia, nitrites, chlorides, and absorbed oxygen).
      • Physical parameters include turbidity and opaqueness.

    Air Pollution

    • Air pollution is a significant environmental health concern, causing both short-term and long-term health effects.
    • Outdoor air pollution (ambient air pollution) is a major contributor to global mortality, with 3.7 million deaths attributed to it in 2016
    • Indoor air pollution (household air pollution) is also a concern, leading to 4.3 million deaths in 2018.
    • Major sources of air pollution include:
      • Domestic fires
      • Industrial exhaust
      • Vehicle exhaust
      • Biomass fuel use indoors
      • Mold, asbestos, and Legionella

    Health Impacts of Air Pollution

    • Short-term health effects of air pollution include headache, nausea, irritation of the eyes, nose, and throat, and acute respiratory infections.
    • Long-term health effects of air pollution include:
      • Chronic obstructive pulmonary disease (COPD)
      • Asthma
      • Cardiovascular diseases
      • Cancer
      • Cataracts

    Solutions to Air Pollution

    • Strategies to address air pollution focus on:
      • The source of pollution: promoting alternative fuels and improved stoves.
      • The living environment/housing: improving ventilation through chimneys, smoke hoods with flues, eaves, and cooking windows.
      • User behavior: using dry wood and keeping young children away from smoke.

    Climate Change

    • Climate change refers to the long-term shifts in weather patterns occurring globally.
    • The primary cause of climate change is rising global temperatures.
    • Climate change has significant ecological and human health implications.

    Impacts of Climate Change

    • Ecological impacts:
      • Glacial retreat
      • Rising sea levels
      • Extreme weather events
      • Species extinction
    • Human health impacts:
      • Heat stress
      • Cardiovascular events
      • Respiratory conditions
      • Vector-borne diseases
      • Gastrointestinal infections
      • Mental health effects

    Sea Level Rise and Bahrain

    • Sea level rise poses a significant threat to Bahrain, impacting coastal areas and development activities.
    • Bahrain has limited capacity to adapt to sea-level rise.
