Concentration of metals in locally grown and organic vegetables

Concentration of metals in locally grown and organic vegetables

By: Stephani Lane & Aaron Pyle


Purpose
Purpose vegetables

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


Overview our experiment
Overview Our Experiment vegetables

  • 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
Metals vegetables

  • Calcium

  • Lead

  • Magnesium

  • Manganese

  • Sodium


Metal benefits
Metal Benefits vegetables

  • 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


Metal detriments
Metal Detriments vegetables

  • 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


Method
Method vegetables

  • 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

Results4
Results vegetables

  • Magnesium


Conclusions
Conclusions vegetables

  • 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
Conclusion vegetables

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