Aqueous slurries of a test sediment spiked withdibenz[a,h]anthracene, 2,4,5,2',4',5'-hexachlorobiphenyl, p.p'-DDE, orphenanthrene were subjected to decontamination experimentation. The spikedsediments were agitated at elevated temperatures for at least 96 hours inthe presence of either of the two contaminant-absorbing media: clusters ofpolyethylene membrane or lipid-containing semipermeable devices (SPMDs).The effects of treatment temperature and surface area of media on theremoval of contaminants were explored. This work is part of a largermethodology for whole-sediment toxicity identification evaluation (TIE). Amethod is being sought that is capable of detoxifying sediments withrespect to organic contaminants...

Rapid ʻŌhiʻa Death is a fatal disease caused by Ceratocystis lukuohia and C. huliohia that are decimating Hawaiʻiʻs keystone trees species, ʻōhiʻa (Metrosideros polymorpha). We developed practical and effective decontamination practices for both cultured C. lukuohia and C. huliohia as well as Ceratocystis spores embedded in ambrosia beetle frass (fine particles of macerated wood or boring dust, beetle parts, and feces). This data release includes data and metadata containing decontamination results of ambrosia beetle (Coleoptera: Scolytinae) frass contaminated with Ceratocystis lukuohia propagules using various laboratory and household disinfectants.
