    Incidence of heavy metals in feathers of birds in a human‐ impacted forest, south‐west Nigeria
    (Wiley, 2019-04) Bada, Adeola A.; Omotoriogun, Taiwo C.
    Hazardous wastes and heavy metal are detrimental to all life forms (Dixit et al., 2015; Sharma, Katnoria, Kaur, & Nagpal, 2015). Organic forms of heavy metals such as mercury and lead can accumulate in living tissues; the health implication ranges from low immunocom‐ petence, failed reproduction to high mortality in a number of taxa (Falq et al., 2011; Fritsch et al., 2010; Hollamby et al., 2004; Kerby, Richards‐Hrdlicka, Storfer, & Skelly, 2010; Scheifler et al., 2006; Webb & Leake, 2006). Unprecedented levels of heavy metals and their neg‐ ative role in biodiversity loss and habitat degradation pose major eco‐ logical concerns (Ayangbenro & Babalola, 2017; Kibria, 2016; Sharma et al., 2015). Despite this fact, less attention is focused on monitoring the levels and impact of heavy metals in the western part of Nigeria. Birds are promising biomonitoring species for heavy metals and xenobiotic based on their use in nondestructive avian matrices, for ex‐ ample feather, blood and egg; and bioavailability, and biotransference in dose‐dependent responses (Becker, 2003; Furness & Greenwood, 1993; Roux & Marra, 2007; Swaileh & Sansur, 2006). Also, as feathers grow in birds, heavy metals are sequestered in the sulfhydryl group of the keratin; the metal residues remained resistant to change in older feather as blood supply stops (Burger, 1993). We investigated the inci‐ dence of heavy metals in passerine birds inhabiting a human‐impacted forest in Ilara‐Mokin, south‐west Nigeria.

    Physicochemical and microbiological assessment of water sources in Ilara-mokin, Ondo State Nigeria
    (Seahi publication, 2018) Bada, Adeola A.; Ajayi, Joshua O.; Momoh, Abdul O.; Enechojo, Abah C.
    The study investigated the physiochemical and microbiological assessment of water sources in Ilara Mokin which were the borehole, stream and well water. Water samples were collected from ten (10) different locations in the community which were ILORO, UBA, HEALTH CENTRE, HOSPITAL ROAD borehole, POJO, UBA, HOSPITAL ROAD stream, TRAVELLER LODGE, UBA ROAD and HOSPITAL ROAD Well. The method used to investigate the study includes the physiochemical and microbiological standard test procedures which includes Gram staining, catalyses, coagulase, Indole, Motility and Sugar fermentation test. The Stream at UBA road and Borehole water at Health centre road contain normal pH of 6.5-7.5. All the water samples were not hard; the Hardness of the water (25- 128ppm) was below the WHO standard which was 200ppm. The conductivity level was below (125.67ppm) and above (770.6ppm) the WHO standard of 200ppm. The temperatures were between 24.5- 27.4oC. The chlorine levels (0.2-0.9Mg/l) were below the WHO standard of 200ppm and the Alkalinity levels (0.1-0.8Mg/l) were below the WHO standard of (200-600Mg/l). The microbiological results showed that the water from Ilara mokin contained some infectious microorganisms. For borehole water sample, it contained Staphylococcus epidermidis, Escherchia coli, Streptococcus mitis , Streptococcus pyogenes, for stream water samples it contained Staphylococcus aureus, Micrococcus varius, , Micrococcus luteus and for well water samples it contained Staphylococcus aureus Proteus vulgaris, , Enterococcus faecalis. These microorganisms are causative agents of many water borne diseases. Ilaramokin should treat their water sources very well before use for domestic and recreational purposes.

    POTENTIAL METAL TOXICITY OF SOME HERBAL PLANTS USED IN THE TREATMENT OF MALARIA IN ONDO STATE, NIGERIA
    (European Journal of Advanced Research in Biological and Life Sciences, 2019-12-31) Bada, Adeola A.; Lawal, S.A.; Arowolo, O.K.; Olabode, K.O.
    Unorthodox medical practice involving the use of herbal plants and other biological specimens, though permissible, is growing unabated in many less developed Nations of the world due to poverty and lack of healthcare facilities without regard to the potential threat/ toxicity from the consumption of these alternative medicines. Thirteen (13) herbal plants commonly used for the treatment of malaria in Ondo state, Nigeria were selected for the study and evaluated for their heavy metal content viz: Cadmium, Zinc, Lead and Chromium using Atomic Absorption Spectrophotometer (AAS).The result showed increased cadmium concentration in the range of 0.014-0.077mg/kg with 76.9% of the selected plants having cadmium concentrations above the permissible limit. Zinc being an essential micro nutrient varied in the range of 0.304-1.539 mg/kg with 100% of the plants within the permissible limits for herbal plants. The lead concentration is within the permissible limit for all the selected plants and in the range of 0.141-0.464mg/kg. Chromium being a trace metal and of toxic potential was detected in 38.46% of the selected plants within the permissible limit and in the range of 0.002-0.356mg/kg. Mangifera indica leaves has chromium concentration of 0.180mg/kg but was not detected in the bark which might be due to anthropogenic influences and gaseous exchange in the leaves. The zinc, lead and chromium levels of these herbs were good for consumption, but cadmium level need to be adjusted to prevent kidney failure during consumption.
