Abstract
Pharmaceutical industries are a necessity for human and animal health, but some of their operations and discharges may pose environmental pollution problems. The aim of this study was to assess the effects of pharmaceutical effluent on the germination, growth and chlorophyll contents of Sorghum bicolor. This was done by exposing the plant to increasing concentrations of pharmaceutical effluent starting from 0 % to 30 % effluent concentrations. From the results, pharmaceutical effluent caused significant reductions (p < 0.05) in all the growth parameters measured. Chlorophyll-a production in the leaves of Sorghum bicolor was significantly (p < 0.05) inhibited by pharmaceutical effluent at every concentration except 1 %, while chlorophyll b and total chlorophyll were not inhibited, but promoted with increasing effluent concentrations.While pharmaceutical effluent caused significant (p <0.05) reductions in the plant’s germination at higher concentrations (15 %, 25 %, 30 %), it promoted germination at 10 % concentration. Pharmaceutical effluent may be used for irrigation at low concentrations after subjecting it to adequate treatment processes.
