Study Notes
Air Pollution in Seaports: Sources and Impacts
- Seaports significantly contribute to air pollution through various activities, including shipping, cargo handling, and land transportation.
Major Air Pollutants in Seaports
-
Nitrogen Oxides (NOx):
- Sources: Primarily from diesel engines in ships, trucks, and port machinery.
- Impacts: Contributes to ground-level ozone formation and respiratory illnesses.
-
Sulfur Oxides (SOx):
- Sources: Primarily from burning heavy fuel oil in ships.
- Impacts: Causes acid rain and respiratory problems, harming human health and the environment.
-
Particulate Matter (PM):
- Types: PM10 and PM2.5 (fine particles).
- Sources: Diesel exhaust, cargo handling, and resuspended dust.
- Impacts: Linked to cardiovascular disease, lung cancer, and premature death.
-
Volatile Organic Compounds (VOCs):
- Sources: Fuel handling, loading/unloading, and certain port chemicals.
- Impacts: Contribute to ground-level ozone formation and various health problems (headaches, respiratory issues).
-
Carbon Monoxide (CO):
- Sources: Incomplete combustion of fossil fuels in port vehicles and machinery.
- Impacts: Impairs oxygen transport, posing health risks particularly to vulnerable populations.
-
Black Carbon (BC):
- Sources: Incomplete combustion of fossil fuels, mostly from ships.
- Impacts: Contributes to climate change by absorbing sunlight and affects human health like other particulate pollutants.
-
Ozone (O3):
- Sources: Formed through photochemical reactions involving NOx/VOCs in sunlight.
- Impacts: Causes respiratory problems and worsens conditions like asthma.
-
Heavy Metals:
- Sources: Industrial processes within ports (shipping, cargo handling).
- Impacts: Accumulate in living organisms, leading to toxic health effects on humans and ecosystems.
-
Formaldehyde:
- Sources: Fumigation, combustion within port operations.
- Impacts: Irritant, respiratory problems, and probable human carcinogen.
Sources of Air Pollution in Seaports by Category
-
Marine Vessels:
- Emissions: NOx, SOx, PM, CO, VOCs.
- Heavy fuel oil use significantly increases SOx emissions; ships account for a portion of global emissions of NOx and SOx.
-
Diesel-Powered Equipment:
- Impacts: Contribute to NOx, PM, and CO emissions.
-
Inland Transportation:
- Can exceed port operations' emissions (e.g., Port of Felixstowe study).
-
Dust from Bulk Material Handling:
- Sources: Loading/unloading, uncovered conveyors.
- Impacts: Contributes to particulate air pollution.
-
Fumigation and Chemical Handling:
- Pollutants: VOCs, formaldehyde (from pesticides/chemicals)
- Impacts: Health risks to workers and surrounding residents.
-
Port Infrastructure:
- Stationary sources (e.g. storage tanks, refineries): release VOCs, heavy metals.
-
Ship Idling:
- Impacts: Unclear impact, mention of auxiliary power, potential emissions.
