<prompt> All of the following methods are used for detecting heavy metals, EXCEPT:Harrison Gilroy test. Paraffin testNeutron activation analysisAtomic adsorption spectroscopy  <response>: All the others except Paraffin test are used to detect heavy metals. These heavy metals are detected from the entrance wound where they are components of the residue discharged from the caridge of a firearm weapon. Harrison Gilroy Test- Sb, Ba, Pb, in firearm discharges. N.A.A. - radioisotopes, A.A.S.- Sb, Ba, Cu. Paraffin testDermal Nitrate testDiphenylamine test- detects NitratesNitrites from a cast of paraffin on the hands, not heavy metals.
