PUBLIC EXPOSURE There is low potential for public exposure to the notified chemical during its storage and distribution. Public exposure to the polymer in Airflex 4530 in anticipated to be minimal since the polymer will be bound to the inner surface of the laminate and the laminate will be available to the public only once the adhesive is cured. The end use of the adhesive containing Airflex 4500 appears to be similar to that containing Airflex 4530. Disposal of the polymer is expected to relate in minimal public exposure. ENVIRONMENTAL EXPOSURE . Release The potential for release of polymer to the environment occurs through spillage in the storage and application areas or during transport to and from storage. This release would be in the form of a liquid which can be treated by containment and adsorption in sand or similar material which can then be disposed of in compliance with local, state or federal disposal regulations, probably to landfill. Manufacturing plant wash water during use of Airflex 4530 will be collected and reused in following batches. For Airflex 4500 wash water containing the notified polymer will be collected and treated prior to release to the waste stream. Spillages and container residues are likely to be disposed of in landfill, where the polymer may persist but is expected to remain immobile. Losses to the environment of the adhesive containing the polymer in the fabrication of the end use product are expected to be low. Closed system application technology is utilised to protect the integrity of the adhesive until applied and allowed to set. Release may also be expected via disposal of articles fabricated the adhesive, probably to landfill or by incineration. Both applications are long lifetime products with disposal on demolition of the building in which the products were integrated. . Fate The main environmental exposure to notified chemical will occur via disposal of waste polymer to landfill, where it is expected to remain immobile. Articles fabricated using adhesive containing the polymer are expected to be incinerated or be consigned to landfill at the end of their useful life. The polymer exhibits characteristics that render it non-reactive and non (or only slowly)- biodegradable when exposed to the environment. In landfill the polymer would likely remain undegraded and if as part of a finished article, attached to the substrate to which it is adhered. ASSESSMENT OF ENVIRONMENTAL EFFECTS No ecotoxicological data were provided, which is acceptable for polymers of NAMW > 1000 according to the Act.
