Lead is a poisonous, soft heavy grey metal that melt easily. Exposure to toxins by human in the environment could pose a great risk to their health, which could be immediate or after several years. Disease manifestation in adults could be traced to their childhood stage where there is likelihood of them to have been exposed to some harmful substances or toxins. This review was carried out to investigate the implications of Lead exposure and toxicity in children. Children have been found to be more susceptible to Lead due to their auto-oral-exploratory, curiosity andage appropriate hand-to-hand behavior which results in their mouthing and swallowing of Lead containing or coated object.

Child’s environment is full of Lead and they can be exposed to it through different sources such as paints, Gasoline, Solder, consumer product and through different pathways. Breastfeeding, Pre-natal, Inhalation, Ingestion of children’s product and toys are some of the sources by which children can get exposed to Lead. Lead can accumulate in the human body over a period of time which could lead to toxic effect in the DNA, Cell, Blood, sense organ, nervous system, reproductive system, digestive system, circulatory system, renal system and skeletal system.

Key words: Lead, Children, Toxicity, Exposure, Diseases

ABSTRACT

The primary objective of this study was to investigate the significance of improvised instructional materials in teaching and learning of Integrated Science. The population of the study consisted of Junior Secondary Schools (JSS1-JSS3) in Ondo West Local Government Area of Ondo State. The sample comprises ten (10) Secondary Schools (these include Five public and Five private schools), twenty (20) students from each school. The research instrument used for data collection was Questionnaire. Data collected were analysed using t-test statistical analysis. The five hypotheses were tested at 0.05 level of significance. The result of the hypotheses showed that there is significant difference between the students taught using improvised instructional materials and those that were not taught with them. It is therefore recommended that improvised instructional materials are very significant in teaching and learning of Integrated Science, and also Integrated Science teachers should be trained in improvising instructional materials and develop positive attitudes toward it. Finally, government was advised to provide more funds for science-based subjects so as to improve the technological capacities and abilities of Nigerians.

 ABSTRACT

Mushrooms are produced on natural materials taken from agricultural waste and lignocellulosic residues produced through the activities of various industries. After mushroom are harvested, “spent” (used) mushroom substrate become available. The aim of this research was to evaluate the mineral and proximate composition of spent mushroom (Pleurotus ostreatus) substrate (SMS), made from composted  Pycnanthus angolensis (African nut) and Spondias mombin (Hog plum) at ratio 9:1 of wood dust: cow dung .The spent substrates obtained after the 2nd flushes was observed to contain all mineral nutrients inquantities that is of agricultural importance. Protein content increased from 15.11±0.02% to 19.10±0.00% in substrates of P. angolensis wood dust.  While there was increase in protein from 15.18±0.02% to 18.96±0.02% and ash from 3.23±0.01 to 9.91±0.01 in substrate of S. mombin wood dust. There was a general increase in the quantity of mineral element except Fe. There was tremendous increase in the amount of Mn in the spent substrates. The highest was observed in spent substrates of Spondias mombin where Mn increased from 23.30±0.00 to 516.30±0.02%. These results show that SMS should be considered as an alternative for the widely used but expensive inorganic resource in vegetable cultivation.

ABSTRACT

The effects of cigarette on First hand smokers (FHS) (smoke which is inhaled into a smoker’s own lungs) and Second hand smokers (SHS) (product of mainstream exhaled smoke and side-stream smoke from the smouldering tips of a cigarette) are considerably known to be hazardous and can cause cancer but the possible effects of cigarette smokes on Third hand smokers (THS) (consists of tobacco smoke pollutants that remain on surfaces and in dust after tobacco has been smoked, are re-emitted and re-suspended back into the air, or react with oxidants and other compounds in the environment to yield secondary pollutants) are relatively unknown and this has brought about a trend of interest in this research work.

Tobacco smoke is known to contain over 4000 chemical constituents which includes human harmful Carcinogens, Tars, Nitrosamines, Poisonous gases (CO), Polynuclear aromatic hydrocarbons (PAHs) etc that can lead to cancer, lung and heart disease, premature skin ageing, delayed wound healing, as well as a number of skin disorders, viral infections such as genital warts leading to cervical cancer, vulva cancer or penile intraepithelial cancer, etc.

Nicotine was extracted from two commercial cigarette, using toluene and barium hydroxide. This was titrated with Perchloric acid in aqueous solution using glacial acetic acid as solvent. The solution was also titrated with different extracts of nicotine from the smoke residues and also from the inhaled portion using suction pump as a means of inhalation.

From data gathered from the experiment above, tobacco from sample A has a total nicotine value of 25.11mg as against the 1.0mg that the manufacturer wrote on it, the smoker only inhales 2.8mg of the 25.11mg of nicotine present while the other 22.8mg are been exhaled into the environment which stores up and forms the third hand smoke laden on walls, cloths, glass wares and re-inhaled. 

From nicotine taken from sample B, the total amount of nicotine extracted was 12.8mg anda the portion inhaled was 4.6mg/ml. this is against the 0.5mg which the producer wrote as the amount of nicotine present in the cigarette. A total amount of 8.2mg were been exhaled into the environment and these are the laden smokes that has effect on non smokers (the third hand effects). This is against the world health organizations’ standards that each cigarette should contain a maximum of 1.0mg inhaled by the smokers.

These observations clearly indicate that the amount of nicotine that is let out in the environment is far greater than the amount of nicotine inhale by the smoker. Therefore people who found themselves in the environment where cigarette is being smoked are of great dangers because, the nicotine left in the environment has higher concentration.

From this research, it is evident that nicotine exhaled into the environment is of higher risk than the one being inhaled by the person who smokes. This is a vital issue as the general public has to be aware of the dangers and risk posed by this high percentage of nicotine being released day by day at pubs, houses, bars and for those who doesn’t smoke but lives with smokers.

Abstract

The syntheses, physico-chemical characterization and antibacterial activity studies of some nickel(II) complexes ofdialkyldithiocarbamates (dtc) mixed with a Schiff base, Methylphenylsalicylaldiminate (MePhSal) are reported in this artile. These dithiocarbamate ligands are diethyl (Et2), dibenzyl (Bz2), di-isobutyl (i-Bu2), di-n-butyl (n-Bu2), Methylbutyl (MeBu), Ethylbutyl (EtBu) Methylphenyl (MePh) and cyclohexyl (c-HxMe). The result of the elemental analyses correspond to 1:1:1 stoichiometry of the nickel(II) ion to the ligands. Infrared spectra studies show bidentatecoordination of the Schiff base to the nickel atom through the azomethine nitrogen and phenolic oxygen while the dithiocarbamate ligands chelated through both sulphur donor-atoms.  The solid reflectance spectra and magnetic moment data of the complexes show d-d absorption bands typical of four coordinate, tetrahedral/square planar geometry. The complexes were tested against strains of some bacteria viz: Staphylococcus aureus and Bacillus subtilis (Gram positive); Escherichia coli, Pseudomonas aeruginosa and Salmonella typhi (Gram negative). The complexes found inactive against all the test bacteria. This may be due to the poor solubility of the complexes in the solvent.

ABSTRACT

Algebra is the cornerstone of functional mathematics and is inadvertently used regularly to solve real life problems. It harks back to the ancient Greeks and Babylonians who used it to solve real life problems. This paper appraises the pedagogical and methodological aspect of teaching of algebra in early child numeracy in Ondo West Local Government area of Ondo State, Nigeria. Ten schools were randomly selected which involved teachers’ population of adequate size while data were collected through questionnaire. The data collected were analyzed and interpreted using chi-square (X²) statistical method. The result of the findings of the research shows that some schools are oblivion of the importance of early introduction of algebra in primary school curriculum. Evidently, early algebra establishes the necessary groundwork for ongoing and future mathematics learning. It is thus imperative for all primary schools that algebra and algebra related activities should be a vital part of primary school mathematics to offer students opportunities for developing more sophisticated thinking skills. Although, in the survey, some believed that age and mental ability of the learner would affect children's understanding of algebra in early grades.  However, it was revealed in the study that effective pedagogy is substantial to understanding of algebra in early grades.

Abstract

Education has always been said to be the bedrock of development. However, for education to take place in its true sense knowledge must be acquired and the acquired knowledge must have resulted in positive change in the life of those who acquired it. The introduction and proliferation of Information and Communication technology (ICT) has greatly affected the availability, distribution and accessibility to knowledge. The twenty first century more than any other century in human history has witnessed tremendous and radical change in information transmission and dissemination. Information is now available anywhere, any place and at any time. This access to information has revolutionized the traditional methods of knowledge acquisition. This paper seeks to examine how web-based learning resources have impacted/impacting on how students acquire knowledge with a view to encouraging or discouraging it.

Abstract

The role of education is very critical to a country’s national development and as such every serious Government puts in place a virile and robust educational policy. In Nigeria education still provide the gateway to her developmental wheel in all spheres of life. Indeed the mode of teaching and learning generally is witnessing a tremendous improvement vis-a-vis the tools utilized to impart knowledge. The role of computer in education globally has redefined the platform of knowledge acquisition tenents. The attitude of learners towards education is a serious and important factor to knowledge transmission which requires a varying pedagogical clime. Therefore the usage of mobile devices to facilitate effective teaching and learning is a strong antidote to meeting the yearnings of the ever curious and restless Nigerian youths of today. This paper critically examines the trends in teaching and learning in Nigerian educational system and the prospect of adopting mobile learning to improve its efficiency.

ABSTRACT

This investigation was carried out to discover the effect of wind on sub surface soil, find its effect and provide a possible solution to it. The research and study was carried out in some selected areas in Ilaje local government area of Ondo state. The investigator wants to find out the main cause of soil and wind erosion in the above selected areas and how it affects the people or masses in the environment. Most times, this environmental problem arises from the action and in action use and misuse of the environment bestowed on man by nature. Mere looking at some street in Ilaje local government like the Abereke Street, Okoona Street and Ugbonla street. The rate at which these areas are being affected is high. Except Ilaje, I have also discovered during the course of my research that some street in Ondo town like Adegoju and Bethlehem are being affected by erosion too. This research work involves the use of questionnaire; interview and personal visits were paid to the selected areas while several interviews were also conducted by the researcher. The main aim of this research work is to find out the erosion problems in the selected areas, to find out its causes, to map out most affected areas and to proffer recommendations and solutions to environmental degradation in the town.
