Wb. Arbuckle et al., TOXICITY OF CUYAHOGA RIVER AND NEARSHORE LAKE ERIE SEDIMENTS TO PHOTOBACTERIUM-PHOSPHOREUM, Journal of Great Lakes research, 21(1), 1995, pp. 64-70
The Cuyahoga River Basin and Lake Erie (nearshore of Cleveland) sedime
nts were assayed with Photobacterium phosphoreum during the summer of
1991. Of the 33 sediments tested, 23 exhibited toxicity using either i
nterstitial or extract water. Nearly all (93%) of the ''navigation cha
nnel'' (i.e., the lower 8 km of the river) and nearshore lake samples
were toxic. No statistical difference was observed between river sedim
ent interstitial and extract waters. With the limited number of lake s
amples (seven), more toxicity was observed with extract water than wit
h interstitial water.
