Abstract
Introduction: With the development of society and people's lifestyle changes/ the use of disposable containers has become inevitable. The use of these containers threatens public and personal health. At  present/ Iran is among the 5 countries with the highest use of these containers in the world. This study is conducted to measure the concentrations of heavy metals including lead/ chromium and copper in disposable containers used in Shahrekord City.
 
Method: For this purpose/ three disposable container samples including foam/ plant/ and plastic  were provided from each company. The total number of collected samples was 72 samples were collected from three different companies.. The samples are extracted based on ISIRI standard and the concentrations of heavy metals were determined by atomic absorption spectroscopy. SPSS was used to statistically analyse the obtained data.
 
Results: The mean concentrations of heavy metals in these containers for copper/ chromium and lead based on foam/ plant and plastic were (8.19/ 7.4/ 0.83- 4.5/ 6.04/ 3.33 and 3.73/ 7.09/ 0) based on the type of container glass/ food container and spoon (5.55/ 6.07/ 2.55- 5.26/ 7.48/ 2 and 4.32/ 6.75/ 0)/ and Iranian/ Ghaem and Kiyani in terms of brand (5.36/ 2.46/ 1.56- 5.68/ 10.76/ 1.68 and 4.35/ 7.1/ 1.12) per kg (mg / kg) of dry weight respectively.
 
Conclusion: The comparison of the amount of metals in disposable containers showed that the average concentration of lead compared to the maximum recommended amount of lead (2 mg.kg) is within the standard limits. And the average concentration of chromium in disposable containers is higher than the maximum recommended amount (1 mg.kg). No certain standard is determined for copper.
