Effects of water-bourne toxicants on regeneration of arms by the brittle star, Ophioderma brevispina, are described. Regeneration was inhibited by 0.1 micrograms liter-1 bis(tri-n-butyltin)oxide and bis(triphenyltin)oxide. Both substances are known to act upon the nervous system, and it is suggested that inhibition was caused by neurotoxicological action of(More)
It is increasingly well documented that a collaborative problem-solving approach is more effective in addressing workplace health concerns than an adversarial approach. Combining this with strategies based on good evidence is key to success. On this premise, a trial was conducted in British Columbia, beginning in July 1999, based on a collaborative approach(More)
Marine unicellular algae, Skeletonema costatum, Thalassiosira pseudonana, and Chlorella sp. were exposed to the industrial brominated compounds tetrabromobisphenol A, decabromobiphenyloxide (DBBO), hexabromocyclododecane (HBCD), pentabromomethylbenzene (PBMB), pentabromoethylbenzene (PBEB), and the herbicide bromoxynil (BROM), in six algal growth media.(More)
The purpose of this study was to compare Optisol to moist chamber storage for maintaining human corneal endothelial barrier function. Human corneas preserved in Optisol were stored for up to 35 days at 4 C. Endothelial carboxyfluorescein permeability (P(ac)) was measured and endothelial ultrastructure was evaluated by electron microscopy. Endothelial P(ac)(More)
of pollution sources of mutagens between locations 3 and 4. The Kamo River appeared to maintain relatively clean water quality from the viewpoint of mutagenic pollution because its level of specific mutagenic activity was much lower than those of locations 4 and 8 at the Katsura River. When mixtures of unknown chemicals such as our extracts are tested in(More)
