Dear Davina

Please kindly  Follow : 

Food and Agriculture Organization (FAO) Heavy Metal Regulations – Faolex. Legal Notice no. 66/2003. 2003. http://faolex.fao.org/docs/pdf/eri42405.pdf.

they have been listed by the US Environmental Agency (USEPA) based on their potential for human exposure and health risk (Birungi et al. 2007).

The joint FAO/WHO Expert  Committee recommended a PTWI concentration

under 5 lg/kg body weights for mercury(Torres-Escribano et al. 2010).

Best regards, parisa

hi Davina , the recent  permissible concentration of lead and cadmium in flesh of fish

are 0.05ug/g wet weight for the Cd and 0.2ug/g wet weight    according to the European community  (EC2008, 2014)

Commission Regulation (EC), 2008. No 629/2008 of 2 July 2008 amending Regulation (EC) No 1881/2006 setting maximum levels for certain contaminants in foodstuffs.

Commission Regulation (EU), 2014. No 488/2014 of 12 May 2014 Amending Regulation (EC) No 1881/2006 as regards maximum levels of cadmium in foodstuffs

for the chromium   nor the WHO and FAO neither the European community have established the permissible values   however there are   some countries such as China  which  fixed  the permissible  concentration of 2mg/g  for Cr

I hope it will help you

best regards

What are the permissible limits of the following heavy metals in soil samples

(Cu, Fe, Zn, Mn, and P)?

JOINT FAO/WHO FOOD STANDARDS PROGRAMME CODEX COMMITTEE ON FOOD ADDITIVES AND CONTAMINANTS Thirty-second Session Beijing, People’s Republic of China, 20-24 March 2000 DRAFT MAXIMUM LEVELS FOR LEAD 0.05mg/kg

Hello ,i have a question about heavy metals in leafy vegetables. The standard 0.2 mg / kg lead is based on the dry weight of the vegetables or wet weight would be grateful if anyone knew how to help.

Hi, I also would like to know what is the permissible limit for Nickel by joint FAO/WHO and MFA. Some research stated 8 mg/kg, while others state 0.5 mg/kg, 0.3 mg/kg and 1.0 mg/kg.

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.

As far as toxic metal concentration limits in seawater and sediments are concerned, you may download a publication of mine entitled: "The Sea Diamond shipwreck: environmental impact assessment in the water column and sediments of the wreck area". If you cannot  download it from Scopus, then ask it from me and I will personally send it to you

Please i need permissible levels for Copper, Iron and Zinc in Fish, Water and Sediment as stipulated by WHO, FAO and any other standard regulation bodies.
