- Abstract
The neutron activation analysis technique was applied to determine several chemical elements in shopping plastic bags in order to evaluate their environmental impact. 40K (from K), 232Th and 238U were also determined to predict their radiological impact. In total, 38 elements were determined including Th, and U. These results revealed that ~ 20% of samples under investigation had Cr exceeded the regulated level for packing and packing waste. On the other hand, 50% of samples have Zn and/or Cr violate the regulated levels in plastic products intended to come into contact with foodstuffs. Models for radiological hazard indices showed that the investigated samples possessed insignificant radiation hazards for human. The obtained data is expected to support the decision-maker in adapting measures to control and manage plastic products, starting from the production stage to the final disposal of the waste.
