✦ Synopsis

The effects of three commonly available antibiotics (tetracycline hydrochloride, streptomycin and neomycin sulfate) on the micro-Winkler and D.O. probe oxygen techniques and on the pH method of CO2 determination were investigated in the laboratory to assess potential effects on community metabolism measurements.

All three antibiotics significantly altered 0, and CO2 concentrations through time. The results demonstrate that the use of the three antibiotics as bacterial respiratory inhibitors in community metabolism studies could cause significant overestimations of community respiration when measured as CO,, and significant underestimation of primary productivity and overestimation of respiration when measured as 0,.

Respiration and ethylene production rates of irradiated apple slices from four apple cultivars were measured for 72 h. Doses less than 1.2 kGy had no effect on rates of CO 2 production and O 2 consumption, and irradiation at doses between 1.2 and 2.4 kGy had minimal effect for all cultivars. Respira

There is a growing trend of characterizing coal and coal wastes in order to study the effect of clays present in them during coal washing. Coarse wastes from the Zonguldak Coal Washery, Turkey, were characterized and found to contain kaolinite, illite, and chlorite. These three clays, obtained in al

Phytoplankton community structure varied between the three lakes and between years within lakes. The Beaverskin Lake phytoplankton community was dominated by cyanophytes and chlorophytes in the summer and chrysophytes in the winter. Kejimkujik Lake was dominated by bacillariophytes in the summer of
