Although chemical analytical measurements are necessary to investigate the composition and magnitude of sediment contamination and to identify possible contaminant sources, these determinations, alone, are inadequate tools for fully characterizing and predicting potential biological effect.
Of these, PAHs were the contaminants of greatest concern based upon exceedance of sediment contamination criteria (Σ16 PAHs up to 1500 mg/kg).
Lyndhurst commissioners said in the resolution that the Passaic's "long history of industrialization" had "resulted in degraded water quality, sediment contamination, loss of wetlands and abandoned or underutilized properties along its shores".
She said the plan addressed the most serious problems facing the lakes like sediment contamination, the proliferation of non-native species, the loss of habitat and the production of fish unsafe for eating.
Anthropogenic activities are driving an increase in sediment contamination in coastal areas.
Accordingly, there is general agreement that sediment contamination is a major concern with regard to environmental quality.
The study has relevance designing control measures and action plans for reducing sediment contamination in anthropogenic impacted rivers.
Index of geo-accumulation permits assessment of the level of sediment contamination with respect to global standards.
By comparing characteristics of different fluvial sediments, such as recent flood deposits or historical sediments, and by monitoring pollutants, the influence of sediment contamination is validated.
Locally highly restricted "hot spots" of soil and sediment contamination evolved as of the Bronze Age, visible even on continental scale geochemical maps[3].
SQGs would be used to assess the extent of sediment contamination, or to implement measures designed to limit or prevent additional contamination.
