The bioaviability of heavy metals in soil and water depends on the pH of the medium. In a large scale scenario affected by climate change will depend by the different factors that interfere with the regulation of soil and water pH. Certainly the increase in CO2 concentration will affect the pH and the potential bioaviability of heavy metals in soil and water but it needs to be well proven.
Dear Yazan,
Herein two additional publications on the topic of concern.
1- Final Report: The Influence of Climate-Induced Alterations in Dissolved Organic Matter on Metal Toxicity and UV Radiation in Rocky Mountain Streams
EPA Grant Number: R829640
Title: The Influence of Climate-Induced Alterations in Dissolved Organic Matter on Metal Toxicity and UV Radiation in Rocky Mountain Streams
Investigators: Clements, William , Baron, Jill S. , McKnight, Diane M. , Meyer, Joseph S.

Objective:
The objective of this research project was to investigate the influence of climate-induced changes in hydrology and dissolved organic matter (DOM) on responses of stream ecosystems to the combined stressors of ultraviolet radiation (UVR) and heavy metals (Figure 1). We hypothesized that changes in climate and UVR will alter the quality and quantity of DOM in Rocky Mountain streams. Because DOM regulates light attenuation and metal bioavailability in these systems, we predicted that exposure to UVR and metals will increase in streams with low levels of DOM.

Hoping this will be helpful,

Yes.
climate change has definite influence on biogeochemical cycles of metals and metalloids too.
The metals and metalloids are very much essential for physiological phenomenon.
So also the metals their mobility and concentrations.
If you look into the oceans (deep) then You can understand what i mean..
