  1. Concentration of metals in locally grown and organic vegetables By: Stephani Lane & Aaron Pyle

  2. Purpose • To determine metal concentration differences between organic and locally grown vegetables for healthy dietary decisions.

  3. Overview Our Experiment • Researched vegetables and metals to test • Determined expected amount of each metal • Purchased vegetables from a local store • Blended vegetables • Made 10, 20, 30, 40 and 50 ppm standards • Ran experiment on the ICP

  6. Metals • Calcium • Lead • Magnesium • Manganese • Sodium

  7. Metal Benefits • Ca- Strong bones, dental care, prevents colon cancer, reduces obesity • Pb- none • Mg- prevent cardio vascular disease, regulates blood pressure, muscle and nerve function • Mn- forming bones and enzymes, helps absorb vitamins, healthy function of the brain • Na- maintains fluid balance maintains healthy heart, eliminates excess CO2

  8. Metal Detriments • Ca- heighten blood pressure, risk of cardio vascular disease, kidney stones • Pb- Headaches, joint pain, fatigue, miscarriages • Mg- Nausea, low blood pressure, irregular heart beat • Mn- Chronic liver disease, psychosis, shaking • Na- high blood pressure, kidney disease, osteoporosis

  9. Method • Weighed out approximately 34 g • Blended each sample with 50 mL of water (100 mL for Broccoli) • Filtered samples through a Buchner funnel • Ran standards • Ran samples

  10. Standard Curves

  11. Results • Calcium

  12. Results • Manganese

  13. Results • Lead

  14. Results • Sodium

  15. Results • Magnesium

  16. Conclusions • Mn found only in organic beets • Broccoli had lower organic concentrations, except for lead • Beets had higher organic concentrations, except for lead • Organic zucchini and potato's were higher in all categories

  17. Conclusion • Based on our data, a healthier dietary decision can be made based on metal content.
