Yes, I suggest you use the INAA method, this is the best technique.

Where,there are many analytical techniques capable of determining the concentration of heavy metal in biological materials (chicken tissue) such as:

- Neutron activation analysis (NAA)

- Atomic absorption spectrometry (AAS),

- Inductively coupled plasma mass spectrometry (ICP-MS),

- Particle induced X-ray emission (PIXE),

- Photon activation analysis (PAA),

- Charged particle induced activation analysis (CPAA), etc.

But the INAA technique (Instrumental Neutron Activation Analysis) has been most extensively used in many areas of life, such as: nutrition, biology, and environment fields, due to its high sensitivity, precision, versatility and multi-elemental character.

Thanks all for your valuable advice

I agree with dr Massaoudi about methods.

tissues weighed and dried at 62 °C until they reached to a constant weight. All samples were ashed in a muffle furnace for 6 hours at 650 °C. Leave to cool, the tissue ash were then dissolved in 2 ml conc. HCl and diluted to 25 ml with 0.1 concentrated hydrochloric acid.

The dilute were kept in plastic bottles and latter heavy metal concentrations were determined using an atomic absorption spectrophotometer.

Heavy metal concentration (μg/g) = reading of atomic absorption × volume of diluted solution / Weight of sample (g).

As suggested earlier, INAA is one of the best methods as no digestion or pre treatment required. Using K0 method, you may not even have to dry the sample, just freeze and analyze for short lived radioisotopes.

Alternatively, XRF can be utilized without digestion.

The best technique is INAA or ICP-MS as Mohammed Messaoudi and othera had suggested. We recently conducted a similar study but using AAS for some selected heavy metals and NaI(Tl) detector for radionuclides due to the non availability of ICP-MS and pur research reactor was undergoing conversion from HEU to LEU at the time of the studies.

Wet digestion by using acid and analyse on ICP-MS, it is better to go through the literature and follow the steps.

neutron activation analysis

Thanks for all....Regards

Neutron activation analysis combined with other chemical methods like AAS, ICP-MS etc. can be used to determine some important toxic heavy metals in chicken tissues.

I agree with Dr. Mohammad Amirul Islam

I agree with Dr. Mohammad Amirul Islam sir.

I suggest combined techniques to achieve chicken analysis. It including NAA, ICP and HPLC.

A method using Laser Induced Breakdown Spectroscopy (LIBS) has been newly develop to analyze such sample. This is still being developed however, but you can take a look on the method.
