This study investigated effect of industrial waste discharge on phytoplankton diversity and composition. This was done through the analysis of selected physico-chemical parameters of the water and phytoplankton diversity. Water samples were collected from four different sites with reference to BIDCO Cooking Oil Refining Ltd, Steel rolling Mills, Sewage Treatment Plant, Leather Industries of Uganda and a sample from open water as control. Physico-chemical parameters and phytoplankton abundance were determined using standard analytical procedures. The results showed that the Secchi depth, temperature, pH and conductivity ranged from 0.77-1.79 m, 27.0-27.9ºC, 6.50-7.00 and 101-153 μS/cm respectively. The highest conductivity value was recorded at the leather industry site. 6.20-7.80. The ranges for dissolved oxygen, total nitrogen and total phosphorus of the water samples were 1.83-5.76 mgl-1, 0.05-0.22 mgl-1 and 0.13-1.51 mgl-1 respectively. The open water site had the highest amount of dissolved oxygen while the leather industry site had the lowest. The highest level of nitrogen was found at the leather industry site. Low oxygen level, high conductivity and high nitrogen level at the leather industry site indicate that this site is moderately polluted. Generally TN: TP ratios were low in the different sites. The phytoplankton of Kirinya Bay was dominated by Cyanophyta that accounted for more than 60% of the total phytoplankton. The sewage treatment plant and leather industries sites had the largest percentages of cyanophytes. The predominance of cyanophytes is an indicator of pollution in the bay. It is recommended that the indiscriminate disposal of the wastes should be discouraged and there is need for each industry to install a waste treatment plant with a view to treat wastes before being discharged into the water bodies.

Sidi, Amina Ibrahim
Urinary tract infection (UTI) is an infection in the urinary tract and caused by bacteria such as Escherichia coli. The objective of the study was to assess the incidence of urinary tract infection among the students at Islamic university in Uganda. The study used a cross-sectional research design in which both qualitative and quantitative statistical technique was adapted. In pursuit of this study, records sets from 2009-2014 were collected from the University (IUIU) health center, forty one (41) samples were selected from the toilets and bathrooms of both male and female hostels using systematic sampling; and two hundred and fifty (250) questionnaires were administered randomly to students in both male and female hostels. Statistical technique like frequencies and percentages, t-test, one-way ANOVA and chi-square were used to analyze data collected using the statistical package for social sciences (SPSS) software and EXCEL. The findings of the study established that there is presence of Escherichia coli and other bacteria in the toilets and bathrooms in both male and female student’s hostels, a high occurrence of UTI among female students than male students in the IUIU main campus and a low level of awareness of students on environmental hygiene but a high level of awareness of the consequences of UTI especially when not treated. The study therefore recommends that the University management should improve in the management of the hostels facilities. Cleaning of the toilets and bathrooms should always be done properly and orientation be given to students on issues of environmental hygiene.

Mohammed, Alhassan Musa
The study assessed the occurrence of controphic species diversity and abundance on mosquito larval population in five categories of habitat in Mbale Municipality. The goal of this study was to determine the diversity and abundance of controphic species that may serve as potential biological control agents for mosquito larvae. The effects of physicochemical parameters on controphic species were also evaluated. A total of 992 species distributed across 11 orders were recorded. Controphic species diversity was lowest in Pond (H’ = 1.39) and highest in Ditch (H’ = 3.47) and Puddle (H’ = 2.48), whereas Mosquito larvae diversity was lowest in rice field (H’ = 0.58) and Pond (H’ = 0.60), and highest in Ditch (H’ = 2.13). One –way ANOVA (post-hoc test) showed that significant differences were observed in the abundance of both controphic species and mosquito larvae across habitat types. Ponds supported the highest number (51.60 ± 7.814) with a range of 31 to74 of controphic species while swamps supported the least (16.71 ± 3.490) with a range of 3 to 27 individuals. That of mosquito larvae, Pond supported the highest number (28.33 ± 8.090) with a range of 14 to 42 larvae while rice field supported the least (16.00 ± 6.807) with a range of 3 to 26 larvae. There was a positive correlation between the diversity of mosquito larvae and that of controphic species (r = .900*) and this was highly significant at (p = .037). Physical chemical parameters varied across habitats, with the pond having the highest amount of ammonia (mean value of 146.920 ± 2.731) while the rice field had the least with mean value of -1.320 ± 0.601. The abundance of controphic species was also positively correlated with phosphorous composition (r = . 971) and was highly significant at (p = .006). These findings should however be treated with caution because data collections lasted a period of only two Months and different techniques were used to collect samples in the different habitat types.

Maishanu, Mansur Haruna
The main objective of this study was to explore the level of community participation in solid waste management in Sironko Town, in light of the challenges and prospects for future management. This study used a cross-sectional research design. Data were collected and analyzed by triangulation in which both qualitative and quantitative approaches were used. Frequencies, percentages, cross tabulation and correlations were used to summarize the data. The findings of the study indicated that the level of public participation in solid waste management in Sironko Town Council was low and on small scale; community members were also not being charged for solid waste disposal by the local leaders and even if this charge was imposed they were not willing to pay for solid waste management. The study therefore recommends that the local government officials strengthen their strategies for sensitization and mobilization of the people so that they can participate in solid waste management. They should also enact a law that will make all the community members to pay a small fee to facilitate the activities involved in waste management. This will encourage cost sharing and will make the community members take responsibility for what they do and thus improve on solid waste management in Sironko town.
