Implications of global climate change for the assessment and management of human health risks of chemicals in the natural environment.

abstract：:OECD (Organisation for Economic Co-operation and Development) Guideline 203, Fish Acute Toxicity Test, states that the test should be performed using at least five concentrations in a geometric series with a separation factor not exceeding 2.2, with at least seven fish per concentration. However, the efficiency of thi...
