Literature Review EFFECTS OF CADMIUM, COPPER, LEAD AND ZINC ON GROWTH, REPRODUCTION AND SURVIVAL OF THE EARTHWORM Eisenia fetida (SAVIGNY): ASSESSING THE ENVIRONMENTAL IMPACT OF POINT-SOURCE METAL CONTAMINATION IN TERRESTRIAL ECOSYSTEMS D. J. Spurgeon, S. P. Hopkin & D. T. Jones Fig. 1. Survival of earthworms in artificial soil contaminated with a geometric series of concentrations of lead. Each point represents the mean of four replicates, each comprising 10 worms at the start of the experiment (i.e. 40 worms per treatment). Fig 2: Growth data for weight change when earthworms were exposed to different concentrations of lead throughout 8 weeks.
