Bioavailability of metal-ligand complexes in hypersaline conditions depending upon the nature of the complex formed.
| Availability | Type of complex |
| Biologically unavailable | (i) Strong insoluble inorganic metal-chloro complexes (ZnCl2, CuCl2) | (ii) Soluble not easily dissociable metal-chloro complexes (CdCl2) | (iii) Biosorbed metal complexes (i.e., metals sorbed on a biotic ligand) |
| Biologically available | (i) Strong soluble lipophilic inorganic metal-chloro complexes (, , , and HgCl2) | (ii) Weak metal-chloro complexes (Fe, Co, Ni, and Mn) | (iii) Metal complexes sorbed to abiotic ligands |
