What the data mean
This indicator is an estimate of the biological oxygen demand (BOD) of effluent discharged into the ocean from waste treatment plants at each continental station.
Increases in readings are expected when occupation of stations is highest (i.e. during warmer months). The treatment plant specifications allow for a BOD range of 0 - 60 mg/l. Results exceeding 60 mg/l are seen as indicative of poor efficiency in the treatment plants. The data shows that while most recent readings are within the acceptable specified levels that some exceedences do occur, especially during summer months.

Australian Antarctic Territory - Environment - Human Pressures on the environment
This indicator is an estimate of the biological oxygen demand (BOD) of effluent discharged into the ocean from waste treatment plants at each continental station. BOD measurements are an indication of the efficiency of the treatment plants in destroying micro organisms being released into the ocean and thus minimising any adverse environmental impact.
Other indicators for this issue:
- AAT-17 Types and concentrations of long range pollutants from outside Antarctica reaching Antarctica
- AAT-18 Annual tourist ship visits and tourist numbers
- AAT-19 Annual catch in tonnes of marine species harvested in Australian Antarctic and sub-Antarctic waters - legal and illegal
- AAT-20 Fishing by-catch numbers and/or weight taken as bycatch
- AAT-21 Station and ship person days
- AAT-23 Annual fuel usage of generator sets and boilers
- AAT-24 Annual incinerator fuel usage
- AAT-25 Annual total of fuel used by vehicles
- AAT-26 Annual total potable water consumption
- AAT-27 Volume of runoffs and pollutants/emissions from stations
- CO-16 Status of Australian fisheries
- CO-17 Change in species and trophic structure of fish species caught
- CO-19 Estimated tonnage taken by illegal fishing; estimated number of illegal boats, estimated number of individuals of threatened species taken
- CO-21 Non-target effects: Number and/or weight taken as bycatch, and change since introduction of exclusion devices
