Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

Fluoride:

It was concluded that accumulation through food chains is of little significance in the aquatic environment.

Zinc:

Zinc is a natural element, natural part of the earth’s crust and present in natural background concentrations in all environmental compartments, incl. Air, water, sediment, soil, biomass.

Moreover, zinc is an essential element that is needed by all living organisms for optimal growth and development.

Because zinc and its compounds are inorganic, the endpoint degradation is not applicable.

Zinc does not bioaccumulate in water or soil.

For metals, the transport and distribution over the different environmental compartments e.g. the water (dissolved fraction, fraction bound to suspended matter), soil (fraction bound or complexed to the soil particles, fraction in the soil pore water,...) is described and quantified by the metal partition coefficients between these different fractions.

Some recent monitoring data on zinc concentrations in the environment are reported in IUCLID section 5.5.1.In evaluating measured levels of zinc in the environment, it is important to consider the natural background.
