Long-term exposure to heavy metals is associated with serious health risks, thus identifying these substances is of great importance in blood, nutritional supplements, and medications. Heavy metal accumulation, such as lead, mercury, cadmium, and arsenic, including their toxic impacts, may bring a series of severe health effects in the biological system, like neurological issues, cardiovascular diseases, and renal dysfunction. This underlines the need to keep an eye on the heavy metal exposure to people and ensure that the health consumer goods do not pose a health risk. With the following atomic-absorption-spectroscopic (AAS) attributes: sensitivity, specificity, and flexibility, it becomes one of the excellent alternative analytical tools to measure heavy metals. Analytically, AAS in its derived form comes highly recommended for the analysis of complex pharmaceutical and biological products. This work contemplates the description and verification of the use of AAS to ascertain the presence and concentration of heavy metals in various kinds of medicines, dietary supplements, and blood samples. The approach was validated according to established procedures, including the construction of a calibration curve, determination of limits of detection and quantification, and recoveries testing made to access the precision and accuracy. Some of the quality control procedures that were there to assure reliability in the findings include reagent blanks, verified reference materials, and duplicate analyses, along with ongoing calibration verification. From the results obtained, it can be concluded that AAS is a very accurate and cost-effective heavy metal analysis method, as the detection limits for all the elements studied were seen at very low levels. This test method could further prove its effectiveness when the results were obtained with readings above the legal safety limits. This was an illustration of the importance that this method ensured that health-related items remained within regulations and protected consumer health. The method established is potent and has a mix of sensitive, accurate, and operational efficiency in regular monitoring of heavy metals.
