Abstract
Risk Assessment and Ecotoxicology Limitations and Recommendations for Ocean Disposal of Mine Waste in the Coral Triangle
Highlights
The Coral Triangle region is located on the equator at the confluence of the Western Pacific and Indian Oceans (Veron et al, 2009)
The development of relevant methods for submarine tailings disposal (STD) risk assessment must include data that address concerns raised by communities that live near discharge areas and rely on those waters for food security
Tests should be developed using a range of regionally relevant species that collectively are ecologically suitable for assessing sediment, water, and porewater toxicities (Figure 4)
Summary
The Coral Triangle region is located on the equator at the confluence of the Western Pacific and Indian Oceans (Veron et al, 2009). Using a weight-of-evidence approach to determine when contamination (elevation in the concentration of substances compared to natural condition) becomes pollution (elevation in the concentration of substances that results in detrimental effects) (e.g., Chapman, 2007) provides a focus for assessing the potential impacts of STD This approach uses multiple lines of evidence, including both chemical and biological measurements with laboratory and field components of study where manipulations are conducted to assist in understanding and predicting future conditions (Chapman, 2007). Discharge Tank Tailings slurry includes metals, particulates, process waste, site waste, sewage
