140 sediment samples from the Hawkesbury River system were analyzed for texture, heavy metals (Cd, Co, Cu, Fe, Mn, Ni, Pb, Zn), organochlorine pesticides (DDT, DDD, DDE, HCB, chlordanes, aldrin, lindane, heptchlor, H-epoxide, dieldrin), and nutrients (organic P, available P, inorganic P, total P, TOC, TKN). The data, sourced from Geoscience Australia, provides a long-term integrated assessment of environmental impact from sources like urbanization, industry, and sewage. It was last updated on 2026-03-25.
Use Cases
- Modeling contaminant source attribution based on heavy metal and pesticide concentrations.
- Assessing eutrophication and algal bloom risks based on sediment nutrient reservoir data.
- Evaluating environmental impact of urbanization and industrial activity on pristine estuarine environments.
- Correlating land use intensity with sediment contaminant levels mentioned in the description.
Strengths
- Analysis of 140 sediment samples provides a substantial spatial snapshot.
- Measures a wide range of contaminants including 8 heavy metals and 10+ organochlorine pesticides.
- Description explicitly links contaminant levels to specific land-use activities and sources.
Limitations
- Row count and column-level documentation are unknown.
- Data freshness should be verified despite the 2026 update date.
- The dataset likely reflects geographic bias specific to the Hawkesbury River catchment.
