Sometimes farmers uses wastewaters to irrigate summer vegetables to face water scarcity.
Which parameters should be measured to assess contamination risk ?
Plant samples should be analysed for heavy metals such as Cd, Ni, Co, Pb, Hg and micro nutrients (Zn, Cumbria, Fe and Mn) content.
In soil where vegetables are grown pH, EC, CEC, heavy metals and micro nutrients analysis should be done

Microbial contamination should also been looked at. This can have a major and direct influence on human health as incidents in the USA due to microbial contamination of vegetables have shown.
