Abstract

This study was carried out with the purpose of assessing solid waste disposal and levels of heavy metals in Fadama area of Sokoto city. A survey using questionnaire and atomic absorp-tion spectroscopy was employed for the study. The descriptive statistics and X2 test were done. The types of pollution noticed include: land (40.0%), air (40.0%), and water (20.0%). The possible causes of the pollution include, mostly open dumping of solid waste (41.7%), then open defecation (33.3%), and lastly burning (25.0%). Spread of diseases was most (40.0%) perceived effect, then effect on children (20.0%) and gastroenteritis (20.0%). Other effects are: sickness (13.3%) and accidents (6.7%). The efforts to address the waste disposal are: burning (60.0%), pushing it away from road (20.0%) and provision of containers (20.0%). Effort did by the government involves, promising to bring con-tainers (30.0%), and doing nothing (70.0%). Wastes found are: plastics (70.0%), organic and defeca-tions (23.3%), metal and relations. The heavy metals analysis shows, the lead ranges from 5.1 ± 1.2 to 10.0 ± 0.80 (ppm); chromium ranges from 0.59 ± 0.01 to 2.10 ± 0.02 (ppm); zinc ranges from not detected to 0.81 ± 0.3 (ppm); cadmium from 0.25 ± 0.02; and mercury ranges from 0.95 ± 0.02 to 10.20 ± 0.11 (ppm). There is poor waste management in an agricultural area, a trend that can seep harmful chemicals to be taken up by plants to the upward food chain/web, coupled with other harmful ef-fects of waste such as instigation of diseases and environmental degradation.

Abstract

A region like Sokoto that is been challenged by series of problems such as double burden of diseases, malnutrition, and food insecurity should utilized the available fruits for their inherent nutrient’s compositions. Therefore, the objective of this study was to assess the proximate and elemental contents (sodium, phosphorus, potassium, calcium, and magnesium) in gingerbread plum (Neocarya macrophylla) fruit which are essential for normal growth and development of body tissues for the human health. Neocarya macrophylla fruit is screened for certain nutritionally needed elements and proximate compositions using standard methods. Results obtained show that, crude protein with (2.70 ± 0.0057%) has the lowest concentration, the moisture content was 5.83 ± 0.57 percent, ash content was 5.33 ± 1.54 percent, crude lipid was 5.23 ± 0.15 percent, and crude fiber was 13.33 ± 4.48 percent. The determined levels of mineral elements (calcium, magnesium, phosphorus, sodium, and potassium) reveal 30.25000 ppm, 4.9001 ppm, 90. 1000 ppm, 40.563 ppm, and 67.5601 ppm, respectively. Therefore, the plant is nutritious and vital for metabolic processes.

Abstract

Nanoparticles play an important role now days in different fields like drug delivery, diagnostics, therapy, engineering, energy, healthcare and Environment.  The goal of this study was to synthesize Silver Nanoparticles from extract of C. dirnum plant, degradation of azo-dyes with synthesized AgNP’s and finding bioactivity of AgNP’s against bacteria’s. The UV-Visible analysis of solution after addition of AgNP’s showed that the addition of silver NP’s reduced the absorbance peak of methyl orange from 2.87 to 1.0 and absorbance peak of methyl red decreased from 2.92 to 1.75. Green synthesis concepts can be used to create metal nano-particles, which have a promising future in the Azo-dye breakdown process. C. diurnum leaf extract acts as a reducing agent to synthesize metal nano-particles, providing environmentally friendly and energy-efficient alternatives. Bioactivity of AgNP's against gram negative and gram-positive bacteria were tested which gave strong inhibition against bacteria.

Abstract

The issue of electronic goods and the pollution they generate is a rapidly growing global concern. These are regarded as any appliances using an electric power supply that has reached their end-of-life. They contain various components, some of which contain harmful substances that cause risks to both human health and the environment. Due to rapid economic growth, urbanization, and increased consumer demand, the manufacturing and usage of electronic devices have a significant increase on the annual growth rate of 5% to 8% compared to other solid wastes. It is in this context that this research aims to assess the awareness and knowledge levels of e-waste pollution, as well as the handling practices and attitudes towards e-waste among residents of Kigali City, Rwanda. The study took place in three districts of Kigali City: Gasabo, Nyarugenge, and Kicukiro, where data were collected using a questionnaire survey administered to a sample of respondents (n=204) living in the city of Kigali. Statistical data analysis was applied on the analysis of the collected information determining the significancy. The results indicated a limited awareness of e-waste pollution among electronic users and identified significant health risks faced by workers and repairers of electronic devices. Thus, a low level of knowledge, noticeable prevalence of inadequate e-waste pollution practices and absence of regulations and legislation concerning e-waste and recycling activities was also identified as a problem. Therefore, educating individuals, raising awareness, and promoting environmental concern implementing the three "Rs", reduce, reuse, and recycle to maximize re-source efficiency and material utilization needs to be enhanced.

Abstract

The consumption of Areca catechu (betel nut) in combination with Piper betel and lime (calcium hydroxide) in Papua New Guinea has been a daily consumable commodity among the country’s population. Due to the increase usage of betel nut, more wastes tend to be deposited into the city’s environment making the city very filthy. The disposal of wastes along with its end byproducts has become a major problem for the environment due to uncontrolled human behavior and ignorance. The city of Port Moresby has seen a lot of wastes from betel nut husks and salivary spittle being spewed all over public places. The uncontrolled wastes disposal and carelessness of the people has significantly affected the outlook of the surrounding environment. Even though, laws were put in place to manage wastes, people do not care of the impacts and continue to ignore the laws. The study was undertaken to understand human behavior and characteristics towards improper waste management and determine the level of wastes derived from the use of betel nut. The study was conducted using simple random sampling and stratified sampling methods through interviews for qualitative data collection. The results revealed that ignorance and carelessness exist within the population in managing betel nut wastes. The results also indicate that banning the sale and trading of betel nut may lead to social and economic problems for most of the unemployed population in Port Moresby. Therefore, it requires a better approach from the government and the city authorities to develop and implement workable win-win solution to the problems faced by the city residence as well as managing their wastes from the use of betel nut.
