The influence of time on lead toxicity and bioaccumulation determined by the OECD earthworm toxicity test (original) (raw)

The study investigates the impact of time on lead toxicity and bioaccumulation in earthworms, specifically using the OECD earthworm reproduction test. It explores whether equilibration time between soil and contaminant solutions is necessary and how mortality and lead accumulation in worms change over time. Findings indicate that both the time factor and lead speciation significantly influence toxicity, suggesting that merely measuring total metal concentration might not adequately assess risk in contaminated soils.
