  Background and Aim: Exposure to heavy metals always causes serious health problems in people working in the industry. Heavy metals may interfere with enzyme functioning or accumulate in specific body organs, leading to various health problems. Cadmium is a toxic heavy metal widely used in various industries and, therefore, workers in metal industries are at risk of exposure to it.

  Materials and Methods: A solid-phase sorbent was synthesized and factors influencing its sorption and elution steps were optimized (R>95%). The validated sorbent (chemically, physically and as regards reproducibility) was used to determine the cadmium content of the worker`s urines.

  Results: Optimized conditions for sorption and elution step were found to be as follows: pH= 7 sorption and elution time (both)= 5 min elution volume= 6 mL, and elution concentration= 2 mol L-1. The great selectivity and the nano-particle size of the sorbent resulted in its highly precise performance (0.6ppb) and high validity and accuracy (CV<3%).

  Conclusion: Using the nano-magnetic sorbent technique and some such laboratory methods as flame atomic absorption spectroscopy, one can easily measure trace amounts of heavy metals in urine. This technique is relatively less expensive and rapid since, when using it, one can omit the filtration and centrifugation steps.
