The environmental concerns about microplastics are growing among scientists, policymakers, and the public. Plastic particles smaller than 5 mm are known as microplastics, and they come from a variety of primary sources, including personal care products and industrial abrasives. Additionally, they come from secondary sources like the degradation of larger plastics. A growing number of these particles have been found in soil, aquatic systems, and even atmospheric samples, highlighting the urgent n...

A growing concern among the global population is the presence of Micro-plastics (MPs) and Nanoplastics (NPs) within various environmental compartments due to their pervasive, persistent presence. Through atmospheric, aquatic, terrestrial, and biological pathways, these particles enter and traverse ecosystems as a result of fragmentation of larger plastics and primary sources such as industrial abrasives and cosmetics. Since they are widely distributed, their presence in soil, freshwater, marine ...

Solar energy is becoming a viable and alternative renewable energy source. The sun generates solar energy, whereas fossil fuels are extracted, which is detrimental to the environment. The availability of fossil fuels is diminishing, although solar energy is plentiful. The utilization of fossil fuels to fulfil our requirements, such as electricity, produces energy applicable to diverse purposes. The combustion of fossil fuels generates detrimental gasses, resulting in air, water, and soil polluti...

This study presents the result of a quality assessment of some sachet water sold and consumed in Ishiagu. Four sachets from each Triplicate batch of the six different brands of 50 cL sachet water were sampled from commonly patronized retail shops by the inhabitants of the study areas, physically ex-amined and assessed for their physicochemical and microbiological param-eters using standard analytical procedures to ascertain the level of compli-ance with World Health Organization (WHO) and Nation...

The objective of this work was to valorize shrimp shell waste to produce chitosan by using an experimental design for the extraction. The centered composite plan was used to optimize the extraction of chitosan. The influent factors were the caustic soda concentration, the temperature and the time. Results showed that the values of answers would adapt to a second-degree polynomial model. For statistical analysis, the R-square value obtained was greater than 98.80%; the Absolute Average (AAD) was ...

In reference to the contribution of natural and anthropogenic activities to pollution levels over Kenya, investigation of the changes in aerosol optical properties during COVID-19 lockdowns was assessed. To achieve its objective the present study used aerosol Optical Depth (AOD), Angstrom exponent (AE) and Single Scattering Albedo (SSA) from Ozone Monitoring Instrument (OMI) and Moderate-resolution Imaging Spectroradiometer (MODIS) satellite sensors, to analyze the variations in aerosol properti...

EDTA synthesized activated carbon derived from sawdust, was utilized as adsorbent for the removal of Pb(II), Cd(II) and Zn(II) ions from aqueous solutions. The adsorptive characteristics and elemental composition of this activated carbon were studied using SEM and EDX techniques respectively, the analysis revealed that SAC-EDTA contained 71.95% by weight of carbon contents which are requisites for the high adsorption capacity. The effect of initial metals ions concentration, adsorbent dose, cont...

The use of fruits both domestically and industrially generates waste from their discarded peels which may lead to environmental pollution and contamination. This work aims at evaluating the effects of chemical pre-treatment of biomass on the physicochemical properties and the effects of process parameters on the production of ethanol via solid-state fermentation. The biomass was dried, ground and subjected to chemical pretreatment using H 2SO 4 and NaOH. pH, total Titratable ...

Diclofenac (DCF) is a non-steroidal anti-inflammatory drug (NSAID) used to relieve pain in joint-related diseases. It is not completely metabolized after consumption and cannot be easily removed using conventional wastewater treatment. DCF has been detected in water bodies and may pose chronic effects on the endocrines of living organisms even at low-level exposure. Heterogeneous photocatalysis provides an alternative and efficient method of degrading DCF. In this study, the photocatalytic remov...

Nowadays, farmers use municipal solid waste compost (MSWC) as fertilizer on their farmlands. Very scarce information on the quality of MSWC compost is available. As a result, the physiochemical characteristics of compost from ten (10) different dump sites in Sokoto City were evaluated in this study, and the results were compared with standards. According to the findings, the compost has a pH value ranging from 6.78 to 7.47, an electric conductivity between 2.16 to 6.48, organic carbon between (1...
