Working on the assessment of heavy metals on consumed fish and chicken from different source points. I need to compare my results with the updated permissible limits of these foods by standard organizations especially FAO and WHO.
Did you already check the FAO and WHO websites ?? If not, why not?
The EU website also contains information.
Also read the attached paper.
Thanks Prof
i've checked the FAO website and was able to get the limits for few metals on both foods. However, the info on the EU website and the paper you supplied was very helpful.
The World Health Organization, WHO, has established as safety metal quantity limits from eating fishes a weekly maximum dosage, commonly known as Provisional Table Weekly Intake (PTWI), per kg of body weight. Taking an average human body weight of approximately 70kg, we can calculate the quantity per person/per week. Therefore, these limits are given in μg/person/week and are the following:
Hg: 5 μg/kgb.w. = 350 μg/person/week = 0.35 mg/person/week
Cd: 7 μg/kgb.w. = 490 μg/person/week / = 0.49 mg/person/week
Pb: 25 μg/kgb.w. = 1750 μg/person/week = 1.75 mg/person/week
Cu: 3500 μg/kgb.w. = 245000 μg/person/week = 245 mg/person/week
Zn: 7000 μg/kgb.w. = 490000 μg/person/week = 490 mg/person/week
Ni: 35 μg/kgb.w. = 2450 μg/person/week = 2.45 mg/person/week
Fe: 5600 μg/kgb.w. = 392000 μg/person/week = 392 mg/person/week
Mn: 980 μg/kgb.w. =68600 μg/person/week = 68.6 mg/person/week
Furthermore the EU Regulation1881/2006/ΕU has established the following maximum concentration limits in fish tissues for Hg, Cd, Pb and these are 0.5 mg/kg, 0.05 mg/kg, 0.30 mg/kg, respectively.
Sana Ullah the essence of research is searching. The answers in this question give you a good start in this activity!
