Molecular screening of microbial communities for candidate indicators of multiple metal impacts in marine sediments from Northern Australia
Coastal sediments accumulate metals from anthropogenic sources and as a consequence industry is required to monitor sediment health. The total concentration of a metal does not necessarily reflect its potential toxicity or biological impact, so biological assessment tools are useful for monitoring. Rapid Biological Assessment (RBA) tools sensitive enough to detect relatively small increases in ...
