1. Is Field Crop Contamination with Heavy Metals an Emerging Concern?

Heavy metal contamination of food, particularly food consumed by infants and young children, with arsenic (As), cadmium (Cd), and lead (Pb) is a major food safety concern in the United States and beginning to draw heightened regulatory scrutiny. Crop uptake of heavy metals also has high spatiotemporal variability due to multiple soil, field, climate and plant factors. Management strategies that minimize heavy metal uptake and translocation are needed. The objective of this field study was to 1)... K. Steinke, Z. Hayden, M. Suplito
