| 520 | |a"At least part of the coastal newsprint-producing pulp and paper industry has switched or plans to switch from zinc hydrosulphite (zinc dithionite, ZnS204) to sodium hydrosulphite (produced on-site by the Borol process) as a brightening agent for groundwood (mechanical) pulp. This switchover is due to the concern about the bioaccumulation of zinc by the Pacific oyster, Crassostrea gigas, which is harvested commercially and recreationally along the British Columbia coast"--Abstract, page i. |
