TLDR
In this paper, the copper concentration of maize at maturity stage reached values from 36.3 to 65.9 µg kg−1 compared to copper levels usually found in non-contaminated crops.Abstract:
We studied copper uptake by maize grown on soils that have been contaminated with CuSO4. In soil the total copper level ranged from 24 to 135 mg kg−1. The copper distribution in soil fractions was assessed by sequential extraction, showing that anthropogenic copper is mainly concentrated in oxides fractions. The copper concentration of maize at the maturity stage reached values from 36.3 to 65.9 mg kg−1 compared to copper levels usually found in non-contaminated crops (5–30 mg kg−1). Here we demonstrate that copper can be accumulated by maize and that copper concentration in maize can be predicted by equations including copper concentration of soil fractions.read more

Copper contamination of vineyard soils from small wine producers: A case study from the Czech Republic
Michael Komárek,Jiřina Száková,Marcela Rohošková,Hana Javorská,Vladislav Chrastný,Jiří Balík +5 more
TL;DR: In this article, the authors focused on evaluating metal contamination of vineyard soils from small wine producers from the Czech Republic using chemical fractionation analyses and found that the highest Cu concentrations were found in the soil from the non-active vineyard, suggesting that contamination of soils from abandoned vineyards should be investigated before changing their use in agriculture.

Potential for phytoextraction of copper by Sinapis alba and Festuca rubra cv. Merlin grown hydroponically and in vineyard soils
TL;DR: The capacity of Festuca rubra cv Merlin and Sinapis alba to tolerate and accumulate copper (Cu) was first investigated in a hydroponic system without the interference of soil chemical–physical properties to reduce excess Cu in vineyard soils.

Biochemical, physiological, and structural effects of excess copper in plants
TL;DR: Copper effects on plant physiology are wide ranging, including interference with fatty acid and protein metabolism and inhibition of respiration and nitrogen fixation processes, and at the whole plant level Cu is an effective inhibitor of vegetative growth and induces general symptoms of senescence.

Evaluation of heavy metal availability in polluted soils by two sequential extraction procedures using factor analysis.
TL;DR: Cd, Cu and Zn labile levels were related to total metal grass contents indicating its suitability for the availability studies in polluted soil-plant system, as well as between the levels of the different sequential fractions and the total content in grass.

TL;DR: P pH and total metals in soil were significantly correlated with the activities of free metal ions, except for Cd(2+), which only had a weak correlation with soil pH.
