    Scientists used tiger worms (Eisenia fetida) to study the ecotoxicity1 of 1080 on soil. The earthworms lived in soil jars with concentrations up to 865 mg of 1080 per kg of soil (856 ppm2). None of the earthworms died, and scientists detected little to no 1080 residues in earthworm tissue after 28 days of exposure.

    1. ecotoxicity: Something that is toxic to the environment.
    2. parts per million: A commonly used term to describe a very small amount of something: one part in one million parts. For example, 32 seconds out of a year is 1 part per million (ppm). In chemistry, a unit of measure for very small concentrations (dilutions). This can be expressed as milligrams per litre (mg/L).
    3. compound: A pure substance made up of two or more different elements chemically combined.

    1080 and water quality

    New Zealand uses 1080 to control introduced pests. Decades of research show that 1080 degrades quickly in water and soil. There are also regulations that protect drinking water supplies. There ...
