I am analyzing heavy metals in soil and water in abandoned copper mine area. I need the background values.Hope your answers would help me.
yes I agree with Prof. Kan
if you google it you will find many papers and also if you search through EPA or WHO sites.
I hope that my paper could help you:

I agree with all above answers! but I suggest to consider your Environmental Conditions.
EPA's Collaboration with the World Health Organization (WHO): According to EPA, the allowable limit of lead, copper and cadmium in drinking water is 0.015 mg/L, 1.3 mg/L, 0.005 mg/L. In the table you will find the limit levels of other pollutants, for example, beryllium 0.004, chromium 0.1 mercury 0.002 mg/L. The EPA works with many countries in Asia, Africa, the Middle East, etc. Permissible concentrations of interest to you pollutants can be found on the EPA website specifically for your country. I recommend to get acquainted ¬

Generally, In the soil, the Ni, Cr and Cd are rich by 24.5 to 44.5, 42.4 to 65.5 and 14.2 to 31.6 μg g-1, enriched by a factor of 3.81, 4.64 and 20.94. I have given the link below which can be helpful for you.

I am actually looking for either WHO or US EPA maximum permissible limit of cobalt in soils of farmlands.
I'm actually working on mining sites. I have an article that has the permissible limits for various heavy metals. Send your email address so that I can send you the article. I'm also interested in that research if you don't mind.
I am searching information about this topic. I will recommend as soon as possible some papers and EPA document, but it is really important to know the reference values per zones.
Please follow the following files to get better clarity about the permissible limits of heavy metals in soil.
