Brief description

The Marine chapter of the 2021 State of the Environment (SoE) report incorporates multiple expert templates developed from streams of marine data. This metadata record describes the Expert Assessment "Pressure of Non-plastic Marine Pollution".

DESCRIPTION OF PRESSURE
In the north east parts of Australia, monitoring and management has been focussed on land-based nutrients, pesticides and sediment inputs while pollution by hydrocarbons is a nation-wide concern. Excess nutrient loads, or the presence of contaminants have the potential to affect the ecological integrity of marine environments. Australia-wide, other threats include microplastics (see marine debris assessment) and pharmaceutical products for which Australia has limited monitoring data (Kroon et al. 2020).
Relative to north-eastern Australia, population density, agricultural activities and coastal development is less intense in the north, south and west coasts where inputs of suspended sediments and pollution (especially metals from spoil or dredging) is understudied but likely to represent a minor pressure on the health of the marine environment (Stoddart et al. 2019).
The use of low sulphur fuel oils (LSFOs) by all vessels is now a mandatory requirement introduced by the International Maritime Organisation (IMO) from January 2020. While the sulphur contents has been reduced to 0.5% m/m (IMO 2019), the physicochemical characteristics of the LSFOs are highly variable and little is known of their fate and behaviour once in the environment, should an accidental discharge occur on Australian coastlines.
