Atomic Absorption Spectroscopic (AAS) Analysis of Heavy Metals and Health Risks Assessment of some Common Energy Drinks

Background and Purpose: Soft drinks are commonly consumed globally. Due to high demand, regulatory protocols may be breached thereby leading contamination with heavy metals. In this study, we determined the content of five metals in some Nigerian soft estimated their potential health risks.
 Methods: Atomic absorption spectroscopy (AAS) was used determine concentrations magnesium, aluminum, lead, arsenic, zinc. Twelve (12) (labeled B1–B12) were used. After AAS, parameters such as target quotient (THQ), average daily intake (EDI), chronic (CDI) evaluated.
 Results: The level arsenic found all ranged from 0.001-0.0603 mg/L, against 0.01 mg/L maximum contaminant (MCL) standard. Lead 0.001-0.023mg/L (MCL is mg/L) within MCL except one sample (0.023 mg/L). Aluminum levels 0.001-2.0491 (0.001 WHO limit 0.02 mg/L. concentration range for magnesium 0.6954-2.4341 versus standard THQ values aluminum significantly different other order abundance was: Mg > Zn Al Pb As. Arsenic lead relatively small compared value most samples higher than normal.
 Conclusion: above acceptable limits drinks. All metals, limits. underscores need quality control measures during production.
