- Mercury Pollution
- Organic forms like dimethyl mercury are more toxic
- Sources
- Fossil fuel combustion
- Industrial activities
- Effects
- Neurotoxin
- Enzyme inhibition in CNS
- Embryonic abnormalities
- Endocrine disrupter
- Symptoms
- Shaking, imbalance
- Minarchata Bay, Japan
- Used an inorganic catalyst for plastic and petrochemical manufacture
- Mercury Pollution
- Organic forms like dimethyl mercury are more toxic
- Sources
- Fossil fuel combustion
- Industrial activities
- Effects
- Neurotoxin
- Enzyme inhibition in CNS
- Embryonic abnormalities
- Endocrine disrupter
- Symptoms
- Shaking, imbalance
- Dumped waste in bay which had a bio-magnifying effect
- Japanese lost muscle control, got dmentia, developmental problems in children
- Sources
- Lead from lead pipes dissolves in water
- Added to petrol to reduce early engine ignition so is released as fumes and partiulates
- Added to paint and released as fumes from pigment
- Released from industrial processes and smelting as lead dust
- Combustion of fossil fuels- esp. coal
- Lead Pollution
- Effects
- Neurotoxin- causes brain damage
- Kidney damage from chronic exposure
- Effects
- Effects
- Neurotoxin- causes brain damage
- Kidney damage from chronic exposure
- Causes autoimmunity
- Developmental problems
- Non-competitive inhibitor of metabolic enzymes
- Developmental problems
- Management
- Bans on leaded petrol and leaded paints
- Use low temperature to remove paint
- Replace lead pipes
- Lead Pollution
- Safer for workers
- Personal protection equipment- respirators
- Fume/particle removing technology
- Management
- Bans on leaded petrol and leaded paints
- Use low temperature to remove paint
- Replace lead pipes
- Heavy Metal Pollution
- Sources
- Metal ore mining
- Smelting
- Industrial processes/products
- Natural sources in soil
- Acid rain
- Accumulative Properties
- Lipophilic
- Accumulate in fatty tissues
- Persistent
- Can't be metabolised
- Not excreted
- Effects
- Toxic
- Non-competitive inbhibitors
- Affects nerve impulses in CNS
- Liver/Kidney/Lung/Bladder/Reproductive Organ damage and disease
- Synergism
- Cadmoum and zinc found in deposits together and affect the body in the same way
- Biomagnifying
- Sources
- Synergism
- Cadmoum and zinc found in deposits together and affect the body in the same way
- Management
- Adding alkaline reagent makes them less mobile and available
