PSM Environment - Complete 1-Day Study Guide (Park's PSM)

---

OVERVIEW: What is Environment?

• Internal environment - internal organs, organ systems (domain of internal medicine)
• External (macro) environment - all post-conception external exposures
  • Physical environment
  • Biological environment
  • Psychosocial environment
• Micro-environment (domestic) - personal lifestyle, eating habits, smoking, drugs
• Also: occupational, socio-economic, moral environment

---

1. WATER

Requirement

• Minimum: 2.5 litres/person/day (drinking + cooking)
• Desirable: 45 litres/person/day (rural), 135 litres/person/day (urban)
• WHO standard: 70 litres/person/day

Water Pollution

• Sewage (most important)
• Industrial effluents
• Agricultural runoff (pesticides, fertilizers)
• Urban runoff

Water-borne Diseases

Water Purification - Household Level

1. Boiling - most reliable; kills all pathogens
2. Chlorination - most widely used; add 2 drops bleach/litre
3. Filtration - candle filter, sand filter
4. Solar disinfection (SODIS) - expose in PET bottles to sunlight 6 hours

Water Purification - Community Level (Steps)

1. Storage/Sedimentation - allows suspended matter to settle (removes ~70% turbidity)
2. Coagulation/Flocculation - add Alum (aluminum sulfate); 5-40 mg/litre
3. Filtration - slow sand filter (most effective; 0.1-0.4 m/hr) or rapid sand filter
4. Disinfection - chlorination (final step)

• Residual chlorine required: 0.2 mg/litre (after 30 min contact)
• Chlorine demand = Chlorine applied - Residual chlorine
• Breakpoint chlorination: all chlorine demand satisfied, free residual appears
• Superchlorination: adding excess, then dechlorinating

Water Quality Standards (WHO/BIS)

Hardness of Water

• Temporary (carbonate) - removed by boiling
• Permanent (sulfate/chloride) - removed by lime-soda process, ion exchange
• Hard water: excess calcium/magnesium; not harmful but wastes soap; protective against cardiovascular disease

Fluoride Problems

• < 0.5 ppm → Dental caries
• 1-1.5 ppm → Ideal (prevents dental caries)
• > 1.5 ppm → Dental fluorosis (mottling of enamel)
• > 3 ppm → Skeletal fluorosis
• > 10 ppm → Crippling fluorosis

Water Testing (Bacteriological)

• Presumptive test → MacConkey broth (35°C, 48hr); gas production = positive
• Confirmatory test → Brilliant green bile broth
• Completed test → Levine EMB agar
• MPN (Most Probable Number) - coliform index; should be 0/100 mL for drinking water

3. Gaseous waste - industrial emissions
4. Biomedical / Hospital waste
5. Radioactive waste
6. Hazardous industrial waste

Sewage

• Composition: 99.9% water + 0.1% solids
• BOD (Biochemical Oxygen Demand): oxygen consumed by microorganisms decomposing organic matter in 5 days at 20°C; indicator of sewage pollution
  • Clean river: BOD < 1 mg/L
  • Moderately polluted: 2-8 mg/L
  • Severely polluted (raw sewage): > 200 mg/L
• COD (Chemical Oxygen Demand): total oxidizable organic matter

Sewage Treatment

1. Preliminary treatment: screening (removes large debris), grit removal
2. Primary treatment: sedimentation (removes 60% suspended solids, 30% BOD); produces primary sludge
3. Secondary treatment (biological):
   • Trickling filter (percolating filter)
   • Activated sludge process (most efficient)
   • Oxidation ponds (cheap, tropical countries)
4. Tertiary treatment (advanced): removes nutrients (N, P), chlorination, further filtration

Activated Sludge Process

• Aerobic treatment; efficient; effluent 95% purified
• Mixed liquor + air → sedimentation → recirculate sludge

Oxidation Ponds (Stabilization ponds)

• Low-cost biological treatment
• Algae produce O₂; bacteria decompose waste
• Retention time: 5-30 days
• Suitable for tropical/rural areas

Solid Waste Management (MSW)

1. Open dumping - worst; vector breeding, leachate contamination (not acceptable)

---

FAMOUS AIR POLLUTION DISASTERS (EPISODES)

Note: The 1952 London Smog is the most frequently examined. The Clean Air Act 1956 was the direct legislative response.

---

ACID RAIN

• Mechanism: SO₂ + NO₂ + water vapour → sulfuric acid (H₂SO₄) + nitric acid (HNO₃) → falls as acid rain
• pH: Normal rain = 5.6; Acid rain = pH < 5.6 (can go below 4)
• Effects:
  • Acidification of lakes and rivers → death of aquatic life
  • Damage to forests (dieback)
  • Corrosion of buildings and monuments (e.g., Taj Mahal, India)
  • Leaching of soil nutrients
  • Urban atmosphere: low pH + high sulfate/nitrate (as in Indian cities)

---

GREENHOUSE EFFECT AND GLOBAL WARMING

• Mechanism: Greenhouse gases trap outgoing infrared (long-wave) radiation from Earth's surface → warming
• Major greenhouse gases:
  1. CO₂ (most important; from fossil fuels) - 55-60% contribution
  2. Methane (CH₄) - from cattle, rice paddies, landfills
  3. Nitrous oxide (N₂O) - from fertilizers, combustion
  4. CFCs (chlorofluorocarbons) - from refrigerants, aerosols
  5. Ozone (tropospheric), water vapour
• Health consequences of global warming:
  • Spread of vector-borne diseases (malaria, dengue, filariasis - expanded geographic range)
  • Sea level rise → flooding, displacement
  • Extreme weather events (heat waves, floods, droughts)
  • Food insecurity, water shortage
  • Increase in heat-related illnesses

---

OZONE LAYER DEPLETION

• Ozone layer: Located in stratosphere, 15-50 km altitude
• Function: Absorbs harmful UV-B radiation (290-320 nm)
• Depleted by: CFCs, halons, HCFCs → release chlorine radicals → destroy O₃
• Ozone hole: Over Antarctica; first reported 1985
• Health effects of increased UV-B:
  • Skin cancers (basal cell carcinoma, squamous cell carcinoma, melanoma)
  • Cataracts
  • Immune suppression
  • Phytoplankton damage → disruption of marine food chain
• Montreal Protocol (1987): International treaty to phase out ozone-depleting substances (CFCs, halons) - most successful environmental treaty

---

INDOOR AIR POLLUTION

• Radon: Radioactive gas from ground/building materials; accumulates in poorly ventilated basements; leading cause of lung cancer after smoking

---

EFFECTS OF AIR POLLUTION (SUMMARY)

(a) Health Effects

• Vulnerable groups: Elderly, children, smokers, chronic respiratory patients

• Soiling and damage to clothing

---

PREVENTION AND CONTROL OF AIR POLLUTION

• Engineering methods: enclosure, ventilation, air cleaning
• "Arresters" for removal of contaminants from industrial emissions

• Switch to electricity, solar power, natural gas, central heating instead of coal
• Phasing out leaded petrol (India switched to unleaded petrol)
• Electrification of transport

• "Green belts" (trees/vegetation) between industrial and residential areas
• Tall chimneys to disperse pollutants (though doesn't eliminate - just dilutes)

• UK: Clean Air Act 1956 (after Great Smog 1952); creation of smokeless zones
• India: The Air (Prevention and Control of Pollution) Act, 1981; Central/State Pollution Control Boards; National Ambient Air Quality Standards (NAAQS) by CPCB
• Powers to local authorities for investigations, research, education
• Enforcement of standards for ambient air quality

• WHO international network of laboratories for monitoring air pollution
• 2 international centres: London and Washington
• 3 regional centres: Moscow, Nagpur, Tokyo; 20 laboratories worldwide
• Montreal Protocol (1987) - CFCs
• Kyoto Protocol (1997) - greenhouse gas reductions
• Paris Agreement (2015) - limit global warming to 1.5°C above pre-industrial levels

---

DISINFECTION OF AIR (Methods)

1. Mechanical ventilation - reduces vitiated air and bacterial density
2. Ultraviolet radiation (UV-C) - effective in operation theatres, infectious disease wards; UV lamps placed in upper part of rooms near air inlet (shaded - direct exposure dangers eyes and skin); also used in public assembly halls
3. Aerosol disinfectants - chemical sprays (limited utility)
4. HEPA filters - used in hospital/clean rooms

---

NATIONAL AMBIENT AIR QUALITY STANDARDS (NAAQS - India, CPCB)

---

METEOROLOGICAL FACTORS AFFECTING AIR POLLUTION

1. Wind: disperses pollutants; low wind speed → accumulation → episodes
2. Temperature inversion: warm air layer traps cold air below → pollutants cannot disperse upward → episodes (London 1952 occurred during temperature inversion)
3. Rainfall: washes down particulates and water-soluble gases
4. Solar radiation: drives photochemical reactions → secondary pollutants (ozone, PAN)
5. Humidity/Fog: combines with SO₂ → sulfurous smog (classical smog)
6. Topography: valleys/basins trap pollutants (Meuse Valley, Donora)
