The study on environmental risk assessment of hospital wastewater at Federal Medical Center (FMC), Umuahia, Nigeria was carried. To this end, the microbial load and heavy metal analyses of the hospital wastewater were determined using established procedures. The wastewater samples were collected directly from the outlet of different wards (Surgical, Children and Emergency wards), with pre-cleaned sterile and dried containers. The result show that they were significant varieties in the bacteria and fungi load of the hospital waste water from the different wards. The bacteria load was on the range of 192×107 cfm/ml to 275×107 cfm/ml (1.92×107 cfm/ml to 2.75×107 cfm/ml) while the fungi load ranged from 1.3×103 to 4.0×103 cfm/ ml as shown in the result, the total aerobic viable bacteria count (TVC) was highest 275×107 in the wastewater for children ward and lowest, 192×107 in the wastewater from the surgery ward. The concentration of lead was in the range 0.02mg/l to 0.09mg/l while cadmium concentrations varies between 0.02 to 0.15mg/l, chromium and copper were in the range of 0.00 to 0.03 and 0.07 to 0.2mg/l respectively, while zinc was found to be between 0.07 to 0.09mg/l and mercury was 0.02mg/l. The result shows that the concentration of the different wards varied significantly (p<0.05). In general, the physicochemical properties of the hospital wastewater samples show that, their disposal into the environmental will impact significantly on the environment. It may be rewarding to treat this wastewater prior to discharge into the environment.

Abstract The primary objective of this glossary is to give clear definitions for those who contribute to studies relevant to these disciplines, or who must interpret them, but are not themselves reproductive physiologists or physicians. This applies especially to chemists who need to understand the literature of reproductive and teratogenic effects of substances without recourse to a multiplicity of other glossaries or dictionaries. The glossary includes terms related to basic and clinical reproductive biology and teratogenesis, insofar as they are necessary for a self-contained document, particularly terms related to diagnosing, measuring, and understanding the effects of substances on the embryo, the fetus, and on the male and female reproductive systems. The glossary consists of about 1200 primary alphabetical entries and includes Annexes of common abbreviations and examples of chemicals with known effects on human reproduction and development. The authors hope that toxicologists, pharmacologists, medical practitioners, risk assessors, and regulatory authorities are among the groups who will find this glossary helpful, in addition to chemists. In particular, the glossary should facilitate the worldwide use of chemical terminology in relation to occupational and environmental risk assessment.
