1 Lead: Criteria Pollutant By Diana Antonio

2 Need Source: EPA.gov

3 Knowledge Base Lead (Pb) Major source =motor vehicles Criteria Pollutant Lead poisoning Affects the oxygen carrying capacity of the blood

4 Knowledge Base Earthworms: model organism Earthworms: model organism

5 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.

6 Literature Review Populations of Earthworms in Forests of the Middle Urals in Conditions of Pollution by Discharge from Copper Works E. L. Vorobeichik

7 Literature Review EARTHWORM (EISENIA FETIDA) BIOASSAY TO ASSESS THE POSSIBLE EFFECTS OF PLATINUM TAILINGS DISPOSAL FACILITIES ON THE ENVIRONMENT ALONG A GRADIENT – L. VAN RENSBURG – P.J. JANSEN VAN RENSBURG

8 Literature Review Earthworm biomass as additional information for risk assessment of heavy metal biomagnifications: a case study for dredged sediment-derived soils and polluted floodplain soils Bart Vandecasteele, Jurgen Samyn

9 Do-Ability Earthworms are attainable from bait stores Earthworms are attainable from bait stores Lead can be in powder form, can be bought Lead can be in powder form, can be bought Soil terrarium for earthworms can be created Soil terrarium for earthworms can be created Hemoglobin can be analyzed Hemoglobin can be analyzed ww.newton.k12.ma.us s/19443.jpg Picture taken by authors, 09
