Hi dear Dr

If you meant determination of heavy metals in nail, hair and ...... we have several methods and references, I attached two of them, if they work please kindly search as these keywords!

As you know : Various techniques have been employed in the detection of trace elements present in human hair. Among others, atomic fluorescence spectrometry,......

Dear Kudeshova Gulchekhra thank you for posting this very interesting and important technical question on RG. In addition to the valuable links suggested by Parisa Ziarati please also have a look at the following relevant literature references which should help you in your analysis:

Heavy Metals in Fingernails and Scalp Hair of Children, Adults and Workers from Environmentally Exposed Areas at Aswan, Egypt

Article Heavy Metals in Fingernails and Scalp Hair of Children, Adul...

Determination of heavy metal concentrations in nails of car workshops workers in Baghdad

Fortunately all three articles are freely available as public full texts on RG. Thus you can download all three of them as pdf files.

In general, atomic absorption technique is a common method for analyzing heavy metal in nails and hair. In this context, please see the following typical publication:

Analysis of Heavy Metals in Human Hair Using Atomic Absorption Spectrometry (AAS)

Data Analysis of Heavy Metals in Human Hair Using Atomic Absorpti...

This article is also freely accessible as public full text on RG.

Good luck with your work and best wishes!

ICP-MS is a good option for determining the trace elements.
