Akoh*, Onuchi Marygem Mac-Kalunta and Okoche Kelvin Amadi</strong></p> <p><strong>Received 25 January 2021/Accepted 22 February 2021</strong></p> <p>The anthelmintic potency of ethanol extracts of Allium sativum was determined in-vivo against a round worm by infecting group of mice orally. Preliminary phytochemical screening revealed the presence of tannin, flavonoid, saponin, alkaloid and glycoside in the plant while anthraquinone was absent. The ethanol extract of garlic was observed to be potent against Ascaris lumbricoides with percentage fall egg count of 80.73% for 200mg/kg of garlic extract 84.26% for 400mg/kg of garlic and 91.78% for 800mg/kg of garlic extract respectively. The acute toxicity effect of the garlic extract recorded was zero (0%) mortality for all dose given to the mice. Allicin, the sulfur-containig compound in garlic acts not only by killing gastrointestinal parasites but also enhances natural immunity of the host.These findings therefore justify the traditional medicinal use of garlic</p> 2021-02-24T00:00:00-05:00 Copyright (c) 2010 The Journal and the author ATR-FTIR Quantitation of Isopropyl Alcohol (IPA) and Ethanol in Some Covid-19 Targeted Hand Sanitizers in Nigeria 2021-03-01T15:51:59-05:00 E.

Gimba</strong></p> <p><strong>Received 05 February 2021/Accepted 20 February 2021</strong></p> <p>The Corona Virus originated from Wuhan, China in the later part of 2019. As at the end of 2020, no medication or vaccine is available for the treatment and/ or control of the Covid-19 pandemic yet. However, preventive measures have been suggested by the World Health Organization (WHO) which include proper and regular personal hygiene and a healthy life style. Regular washing of hands using soap and water and the use of Hand sanitizers have been suggested as the first line of defense against the SARS COV2 virus. In this study, the Shimadzu FTIR-8400S Fourier Transform Infrared Spectrophotometer with Attenuated Total Reflectance (ATR) accessory was used for the quantitation of the isopropyl alcohol (IPA) and Ethanol content of nineteen (19) different brands of hand sanitizers used in Kaduna state, Nigeria and its environs for the non-pharmaceutical prevention of COVID-19. Results revealed an Isopropyl alcohol concentration in the range of 10.155% to 85.684% and an Ethanol concentration in the range. Of the nineteen samples studied, five had an IPA concentration below 50%. Nine of the samples had concentrations above the World Health Organization (WHO) recommended 75%. The implications on the health of the populace, with respect to the efforts to combat and contain the ravaging SARS COV-2 virus and the resultant COVID-19 are discussed</p> 2021-02-22T00:00:00-05:00 Copyright (c) 2010 The Journal and the author Geochemical Characteristics of the Cretaceous Emewe–Efopa Coal in the Northern Anambra Basin of Nigeria 2021-03-01T21:52:28-05:00 Felix B.

Omada</strong></p> <p><strong>Received 05 February 2021/Accepted 20 February 2021</strong></p> <p>Geochemical analysis has been carried out on coal samples from Emewe–Efopa coal in the northern Anambra Basin of Nigeria. The study was carried out mainly to determine the geochemical characteristics of the coal and its industrial potentials. Results of proximate analysis indicated that the coal contains 12.63% moisture, 5.71 % ash, 46.65 % volatile matter and 35.01 % fixed carbon. Ultimate analysis results also revealed that the coal consists of 60.99 % carbon, 5.37 % hydrogen, 1.25 % nitrogen, 13.01 % oxygen, 1.06 % sulphur and 0.013 % phosphorus. The average heating value of the coal is 11,084 Btu/1b while its free swelling index was calculated at 0.0. The results led to the conclusion that the coal is only appropriate for electricity generation, heating boilers and ovens in industrial process heating, manufacturing organic chemicals and production of gas and automotive fuel.</p> 2021-02-23T00:00:00-05:00 Copyright (c) 2010 The Journal and the author Radiological Assessment of Primordial Radionuclides in Crab Species from Igbokoda River in Southwest of Nigeria 2021-03-01T15:17:27-05:00 Olusegun Sowole Adesoji A.

Adebambo</p> <p><strong>Received 30 January 2021/Accepted 11 February 2021</strong></p> <p>Primordial radionuclides are natural radionuclides of specific half-lives that are capable of disintegrating with the release of ionizing radiations along with huge amount of energy which can be so harmful to living organisms. Activity concentrations and radiological indices of <sup>40</sup>K, <sup>226</sup>Ra and <sup>228</sup>Ra in crab species from Igbokoda River in the coastal area of South Western Nigeria, have been determined using gamma spectrometry method. Twenty (20) samples of three different species (Callinectes latimanus, Callinectes amnicola and Cadiosoma armatum) of crabs were collected from the River. The results obtained indicated that the highest dose rates of <sup>40</sup>K, <sup>226</sup>Ra and <sup>228</sup>Ra were associated with Callinectes latimanus while the highest annual committed effective dose of <sup>40</sup>K to man was 0.0026mSvyr<sup>-1 </sup>and was associated with Callinectes latimanus for <sup>226</sup>Ra (0.0068mSvyr<sup>-1</sup>) and <sup>228</sup>Ra (0.0208mSvyr<sup>-1</sup>). The highest excess lifetime cancer risk associated with <sup>40</sup>K, <sup>226</sup>Ra and <sup>228</sup>Ra 0.0237 x 10<sup>-3</sup> 0.0728 x 10<sup>-3</sup>. All the values obtained were within the limits recommended globally; indicating that there was no significant radiological health implication to the aquatic animals and man the consumer</p> 2021-02-16T00:00:00-05:00 Copyright (c) 2010 The Journal and the author
