- Environmental Bioconcentration: Cinquasia red should not bioconcentrate, since it is insoluble, and therefore, will not be taken up into the body. Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: Much of cinquasia red will be bound up in the components of landfills, junkyards, and general dump sites. Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: Terrestrial: The insolubility of cinquasia red will cause it to collect in soils and sediments. Source: Hazardous Substances Data Bank (HSDB)
