Abstract Maintaining air quality is an important and effective approach to mitigating
the virus pandemic in that, the quality of air is important in creating,
sustaining or inhibiting conditions for virus viability. Polluted air is the most
significant environmental risk factor for all-cause mortality. Exposure to
poor air-quality may exacerbate symptoms, trigger a severe course of the
virus and for the most vulnerable population, and eventually be fatal. The
morbidity posed by air pollution and its impact on our current situation
must not be overlooked in the midst of our unprecedented coronavirus
pandemic. In-situ CO data from ten (10) shops at different locations in
Agbor, Delta state, Nigeria were monitored between the hours 7.00am-
6.00pm thrice weekly for the period January to March,2021 using BK
PRECISION 627 carbon-monoxide sensor. Statistical correlations between
the indoor and outdoor values were calculated. One of the main findings
indicates high CO values in some of the shops. The Centre of Research on
Clean Air reported that greater levels of air pollution interfere with the
body's normal defense against air borne viruses including SARS-CoV-2. The
findings suggest a potential for local traffic management strategies to
reduce ambient exposure, minimize exceedances of air quality standards
for pollutants and, optimize ventilation based on occupancy and activity.Maintaining air quality is an important and effective approach to mitigating

Abstract The present study was conducted at three stations along Omve stream,
Ovu Inland Ethiope East LGA, for six month (January to July 2019). Total of
24 fish species, from 15 families and 19 genera were recorded Among the
24 species 62.56 occurred in station 1 while 72.2% occurred in station 2
and 50% occurred in station 3. Only 33.3% of the species were ubiquitous.
The Cichlid family Tlapia Zillii and the family Clariid, Clarias syp were the
most dominant in the stream, accounting for 18.46% and 12.02% of the
total catch, respectively. The species richness and general diversity were
relatively higher in station 2 than in any other station With good fishing
management, the fishery resources of the stream can be profitably
exploited. Beside the Cichlids had the highest condition factor values than
any other fish family.

Abstract Background and Aim: Chitosan can also be used in toothpaste, mouth
washes, and chewing gum. They freshen the breath and prevent the
formation of plaque and tooth decay. Salts of chitosan added to toothpaste,
mask the unpleasant taste of silicon oxide and bind powders so that they
maintain their granular shapes. The aim of this study is to modify chitosan
with some aldehydes and the obtained product characterized and tested
towards their metal ion uptake application.
Materials and methods: Chitosan was produced by complete deactivation
of chitin from crustacean shells (snail shells). The chitosan produced was
used to prepare cinnamaldehyde chitosan and Acetic Anhydride chitosan.
Fourier Transformed Infrared Spectroscopy (FTIR) analysis of the pure
chiatosan and cinnamaldehyde chitosan were carried out. The FTIR
spectrum of unmodified chitosan had strong peaks observed at 3640.58cm
-1 due to O-H stretching, the bands at 1413.33cm-1 for C-H bending and the
band at 1632cm-' was assigned to N-H bending.
Results/ Discussion: After the chemical modification, some changes were
observed in the spectra of cinnamaldehyde chitosan. The two products:
chitosan and cinnamaldehyde chitosan were applied for the adsorption of
Cadmium and Nickel from aqueous solution and their percentage sorption
were compared. Cinnamaldehyde chitosan gave 99.56% at an optimum
concentration of 80ppm while unmodified chitosan gave 98.61% at an
optimum concentration of 80 ppm
Conclusion: From this investigation, we can infer that the chemical
modification of chitosan with the different organic compounds can lead to
promising materials in the light of their application directions. The modified
chitosan products showed good ability to uptake metal ions from their
aqueous solutions.

Abstract Aim: The aim of this research was extraction, phytochemical studies and
GCMIS analysis of Aspilia africana.
Place and Duration of Study: This study was carried out at the University of
Benin, Benin-City and University of Lagos Central Research Laboratory,
Nigeria from January 2016 to September 2016.
Methodology: 200 g of the pulverized plant sample was extracted with
hexane, chloroform and methanol in this order for 8-12 hours. The extract
was concentrated using a rotary evaporator to obtain the crude extract. The
phytochemical test was carried out using standard methods. The GCMS
was carried out using Agilent Technologies 7890A couple with Agilent
Technologies 5975C VL MSD. The mobile phase is helium gas while the
stationary phase was the column agilent technology HP5 MS with length
30m, internal diameter 0.320 mm and thickness 0.25 microns. The volume
injected is 1 microlitre, oven initial temperature was 80°? to hold for 2
minutes. The mode was split less and scan range was 35-55.
Results: The phytochemicals of the leaves of Aspilia africana were
extracted with chloroform by Soxhlet method and analysed using GC-MS.
Ten constituents were identified constituting 92.714% hydrocarbon.
Caryophyllene (29.43%), 2-Carene (19.76%) and Germacrene D(33.3%)were
the major components of the extract. The phytochemical analysis was
carried out by standard methods. The results revealed the presence of a
number of therapeutically important phytochemicals such as alkaloids,
terpenoids, tannins, flavonoids, saponins and glycosides in the extract.
Conclusion: The results of the phytochemical screening and GC-MS
analysis indicate that the leaves of Aspilia africana are a rich source of a
number of bioactive secondary metabolites which include alkaloids, tannins,
saponins, flavonoid, glycosides and terpenoids. This justifies the use of the
plant in the traditional practices of herbal medicine, especially in the
treatment of microbe-induced disease conditions.

Abstract Aim: The aim of the research was to analyse the minerals and proximate
content of soya bean in order to explore its nutritional values in human and
animal diets.
Place and Duration of Study: This study was carried out at Edo
Environmental Consults and Laboratory Limited (EECL), Benin-City and
Delta State University, Abraka, between March, 2010 and January 2011.
Methodology: The standard procedures were followed to analyse the
proximate compositions and mineral concentrations of soya bean flour.
The caloric value was calculated from crude protein, crude fat, crude fiber,
carbohydrate, moisture and ash content. The Iron (Fe), Zinc (Zn), Calcium
(Ca), magnesium (Mg), and cadmium (Cd) were determined by Atomic
Absorption Spectrophotometer (AAS), sodium (Na) by Flame
Spectrophotometer and phosphorus (P) by Spectrophotometer.
Results: The result revealed that soya bean contained 37.69% of protein,
28.20% of crude fat, 4.29% of ash, 8.07% of moisture, 5.44% of fibre,
16.31% of carbohydrate. The mineral determination showed that soya bean
contained 300.36 mg/100 of Calcium, 258.24 mg/100g of Magnesium,
16.4 mg/100 g of Iron, 3.0 mg/100 g of Sodium, 2.7 mg/100 g of Zinc,
695.20 mg/100g of Phosphorus, 469.80 kCal/100g while Cadmium was
below detectable range.
Conclusion: This study concluded that the tested soya bean contained the
highest amount of protein and lowest amount of ash. Similarly, among the
minerals tested soya bean contained the highest amount of phosphorus
and no cadmium at all. Considering the nutrient contents and proximate
analysis of the sample, soya bean should be an inexpensive source of
macronutrients that could be used in the management of protein-energy
malnutrition and to improve the nutrition status of the vulnerable group of
the population in developing countries. In developed countries, it could be
used to improve the nutrition status of functional foods.

Abstract Chitosan was produced by complete deacetylation of chitin from crustacean shells (snail shell).
ForrierTransfomInfra-red Spectroscopy(FTIR) analysis of the unmodified chitosan and Acetic anhydride
chitosan were carried out. The FTIR spectrum of unmodified chitosan has strong peaks observed at
3640.58cm-1 and the chemically modified acetic anhydride chitosan at 3278.44cm-1. The two products:
chitosan and Acetic Anhydride chitosan were applied for the adsorption of cadmium and Nickel from
aqueous solution using a UV-visible Spectrophotometer (model JENWAY 6320D) and their percentage
sorption was compared. It was observed that the modified chitosan with Acetic Anhydride, showed good
ability for metal ion uptake.The amount Cadmium and Nickel absorbed was found to increase with
time.Results also indicate that the adsorption capacity of metal ion increased with temperature. The high
percentage adsorptions of the materials are due to the additional functional groups present in the
samples. It took about 120 minutes for acetic anhydride modified chitosan to reach equilibrium at which
a higher percentage sorption (86.50%) was obtained, while unmodified chitosan gave (82.50%).
