AB  - The detection of silver in nano-plastic food packaging by microwave digestion 
      coupled with either inductively coupled plasma atomic emission spectrometry 
      (ICP-AES) or inductively coupled plasma mass spectrometry (ICP-MS) was 
      investigated. Microwave digestion was optimised by trialling different acid 
      mixtures. Both ICP-AES and ICP-MS showed good reproducibility, repeatability and 
      recovery. For ICP-AES the limit of detection of the method (LODm) was 
      25.0 microg g(-1), the limit of detection of the instrument (LODi) was 
      30.0 ng ml(-1), the linear range was 0.10-10.0 microg ml(-1). The average recoveries 
      for blank samples spiked with silver at 100, 250 and 500 microg g(-1) ranged from 
      82.53% to 87.60%, and the relative standard deviations (RSDs) were from 1.79% to 
      8.30%. For ICP-MS analysis the LODm was 0.75 microg g(-1), the LODi was 
      0.04 ng ml(-1), the linear range was 0.20-500.0 ng ml(-1), the RSDs were 
      2.26-4.79%, and the recoveries were 78.09-92.72% (spiked concentrations of 2.5, 
      5.0 and 10.0 microg g(-1)). These results indicate that the proposed method could be 
      employed to analyse silver in nano-plastic food packaging.
