DOI: 10.1016/j.envpol.2016.11.038
Abstract: Many benthic communities within estuarine ecosystems are highly degraded due to the close proximity of urban and industrial contamination sources. The maintenance of recolonised, healthy ecosystems following remediation is a challenge, and better techniques are… read more here.

DOI: 10.1016/j.envpol.2019.04.003
Abstract: Metal flux measurements inform the mobility, potential bioavailability and risk of toxicity for metals in contaminated sediments and therefore is an important approach for sediment quality assessment. The binding and release of metals that contribute… read more here.
