Multi-element spectrometric analysis of stingless bee honey in Johor for forensic provenancing application

Consumption of stingless bee honey as nutritious food supplement has been gaining popularity in many countries including Malaysia. However, its safe consumption following the possible presence of toxic amounts of trace elements remains unclear. Hence, this cross-sectional research that assessed the...
