Bushmeat have provided complimentary protein for human population across the world over the centuries. This study assessed the concentration of heavy metals in bushmeats in New Bussa and its environs. Three carcass of bush meat (Kobus kob (Kob), Tragelaphus scriptus (Bushbuck) and Sylvicapra grimmia (Duiker)) were sourced from the study area. The carcass was digested and concentrations of nine heavy metals (Mn, Fe, Cu, Zn, Pb, Cr, Ni, Co and Cd) were determined using Atomic Absorption Spectrophotometer (AAS). Results obtained for the heavy metal analysis were subjected to one-way analysis of variance (ANOVA) while Pearson’s correlation was used to determine the relationship in the samples. The heavy metal concentration in muscle tissues of the selected bushmeat revealed that zinc with 815.00±13.00 mg/kg in Kob was the highest mean value of all meat samples, followed by Iron (479.00±10.00 mg/kg) in Duiker while Pb level in Bushbuck 213.00±3.00 mg/kg is outrageously the highest. Copper, Chromium and Nickel did not exceed the permissible limits as set by FEPA/WHO. The concentration pattern of heavy metals in bush meat show that Sylvicapra grimmia and Tragelaphus scriptus had the same pattern of Zn>Fe>Pb>Cr>Mn>Cu>Co>Ni>Cd concentration while Kobus kob pattern of association is Zn>Fe>Cr>Pb>Ni>Cu>Co>Cd>Mn. The comparative study of the heavy metal concentrations revealed that Zinc (Zn) recorded the highest frequency, followed by Iron (Fe) and Lead (Pb). This study has shown that high level of Pb in the samples from the study area is a matter of concern in bush meat consumption in the study area; hence people should be warned of impending danger in the consumption of heavy metals contaminated bush meat.

Assessment of Environmental and Recreation Facility Maintenance was carried out in Kainji Lake National Park. Questionnaire method of data collection was employed to collect the data needed. Purposive and simple random techniques were adopted to sample respondents in the study area. One hundred questionnaires were designed and administered. The data collected were analyzed through simple percentage and presented in table and charts. However, the results showed that recreation facilities are 99% present, while swimming pool is 65% functional. The study showed that visitors came there three times in a week indicating 44% of the respondents while on maintenance of the park environment and the facilities indicated 94% and 88% of the respondents respectively. The study further recommended the followings facilities basketball pitch. Hockey game, volley ball and well-constructed swimming pool.
Infection with gastrointestinal parasites is a major health issue in captive birds; prevalence data of gastrointestinal parasites of birds in Zoological gardens in Nigeria are limited. This study was carried out to determine the gastrointestinal parasite kept at University of Ilorin Zoological garden. A total of 21 fecal samples from 9 birds were examined using fecal sedimentation technique. The overall prevalence of gastrointestinal parasites was found to be 71.4%, with the highest prevalence of infection recorded in Ostrich, Crowned crane and African fish eagle (100% each), followed by domestic pigeon and White-faced whistling duck. While Marabou stock, White peafowl and Emu were the least with 50.0% each. The distribution of gastrointestinal parasites in the study area revealed a total of four species of parasites which includes two protozoans (Coccidian and Eimeria spp.) and two nematodes (Capillariaspp and Ascaris spp.) The intensity of gastrointestinal parasites of birds in the study area revealed that Ascaridiagalli recorded the highest intensity of 358 epg, followed by Capillariaspp with 104 epg while Eimeriaoocysts recorded the least intensity of 70 epg. The study concludes that the birds at the University of Ilorin Zoological garden harbor parasites which are of great importance to their health and also that of the staff and visitors in the zoo because most of the fecal samples examined did not show any obvious clinical signs.
This study assesses heavy metals distribution in body parts of Labeo coubie (African carp) fromRiver Oli, in Kainji Lake National Park as pollution index of the ecosystem. Fish parts samples (gills, muscles andvertebra bone) were prepared and specifically analyzed for the levels of Pb, Cr, Zn, Cu, Fe and Cd using Atomicabsorption spectrophotometry. The concentration of metals in the samples at different concentrations ranged from0.001±0.000 μg/g for Cd to 224.87±4.07 μg/g of Fe in the fish gill. There is significant (p<0.05) differences in the Pb,Zn, Cu and Fe concentrations across the different fish parts with gills accumulated the highest levels metals while Crlevels significantly (p<0.05) differed in the fish body parts and accumulated more in the muscles (10.75±0.15 μg/g).The mean concentrations of metal elements in the fish parts had shown some distinguish connection in its distributionswith Pb and Cu; Gills > Muscles > Vertebra bones, Fe and Zinc; Gills > Vertebra bones > Muscles while Cr wasdistributed in Muscles > Gill > Vertebra bones. However, it is revealed that Labeo coubie, a euryphagus fish probablyabsorb these metals through ingestion of contaminated food or absorption by the gills and bioaccumulate in differentfish parts. It is therefore established that River Oli is contaminated with heavy metals as presence of these metals infish is an indication of its immediate environment.
