Regular dangerous metal screening is an important component of ecological assessment, particularly in locations experiencing industrial activities or historical mining. This process typically involves collecting materials of ground, liquids, or living organisms and then testing them for the presence of various dangerous metals such as Pb, As, Cd, a

Quantitative analysis plays a crucial role in assessing the levels of heavy metals in environmental samples. Various measurement techniques, including flame atomic absorption spectrophotometry (FAAS), are employed to determine the concentrations of heavy metals such as lead, mercury, arsenic. These analyses provide valuable insights the potential r
