Concentration of metals in locally grown and organic vegetables By: Stephani Lane & Aaron Pyle
Purpose To determine metal concentration differences between organic and locally grown vegetables for healthy dietary decisions.
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
Metals Calcium Lead Magnesium Manganese Sodium
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 CO 2
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
Conclusion Based on our data, a healthier dietary decision can be made concerning metal content.
