Abstract

This research aimed to investigate how combining process variables affects biogas production from anaerobic digestion of food waste and rumen contents. A mixture design was used to evaluate the effects of temperature, pH, agitation frequency, and retention time on biogas quantity and quality. Anaerobic mono-digestion and co-digestion were performed using 2 liter single-stage plastic anaerobic digesters. Cumulative biogas volume and its composition, including carbon dioxide, hydrogen sulphide, moisture, and methane content, were estimated volumetrically. The highest biogas volume and quality were obtained under the following conditions: food waste (0.30 kg), rumen content (0.30 kg), water content (0.40 kg), temperature (34.0° C), pH (9.0), agitation frequency (4 times/day), and retention time (32 days). Combining process variables can significantly impact biogas quantity and quality, and optimal process parameters vary depending on the substrate and operational conditions. Anaerobic digestion can effectively manage organic waste, produce renewable energy, and mitigate greenhouse gases.

Abstract

In response to the challenges posed by organic soil contamination, a promising approach involves the application of biochar. This study investigates the effects of biochar derived from corncobs on soil organic matter, organic carbon, and soil microbial biomass carbon through one-factor factorial design experiments. Crushed corncobs were subjected to pyrolysis at 300 °C to produce corncobs-biochar, which was incrementally added to pots containing four different levels of paddy soils. Results indicated a significant enhancement (p<0.05) in the physicochemical composition of samples and improved acid degradation upon the addition of corncob-biochar with pH increasing from 1.3 in control to 9.10 in the highest treatment (TP4), along with notable improvements in electrical conductivity, cation exchange capacity, and organic carbon levels. The most effective biochar applications, TP3 and TP4, demonstrated improved nutrient retention and reduced soil acidity. This suggests that incorporating corncob-biochar into the soil can ameliorate acidic conditions and sequester carbon for future ecosystem use. In conclusion, amending soil with corncob-biochar demonstrates a notable enhancement in soil quality. The environmentally friendly application of corncob-biochar could be recommended by offering a sustainable and economically practical strategy for enhancing soil quality, addressing soil degradation, and promoting long-term agricultural productivity.

Abstract

Soil erosion in semi-arid regions contributes significantly to groundwater contamination, particularly through sediment-laden runoff entering shallow aquifers. The intensification of rainfall events has accelerated surface erosion, leading to increased transport of sediments and contaminants into shallow wells, which serve as the primary water source for many households. This study investigated the extent and mechanisms of groundwater contamination in twelve selected wells around Kwarin Awaja, focusing on changes in water quality before and after major rainfall events. Water samples were analyzed for turbidity, electrical conductivity (EC), pH, coliform bacteria, nitrates, and heavy metals (cadmium and chromium). Results showed significant increases in turbidity, nitrates, total dissolved solids, chloride, sulphate, and electrical conductivity after rainfall, indicating erosion-induced pollutant infiltration. Paired sample t-tests revealed significant post-rainfall increases in turbidity (up to 12.1 NTU) and EC (up to 675 µS/cm), with values exceeding national standards such as Nigeria Standards for Drinking Water Quality (NSDWQ) in wells closest to active erosion sites. Pearson correlation analysis showed strong associations between proximity to erosion features and elevated pollution indicators. Microbial contamination, absent before rainfall, was detected in several wells after rainfall events. The findings highlight the vulnerability of shallow groundwater to erosion-driven pollution and underscore the need for targeted interventions to protect water quality in erosion-prone rural environments.

Abstract

The rapid increase in population has greatly intensified the requirement for safe and clean drinking water, giving rise to the widespread use of packaged sachet water, commonly known as “pure water” in Nigeria. However, issues concerning improper handling during production, distribution, and storage raise questions regarding possible contamination. This research analyzes the physicochemical and microbiological quality of sachet water in Dutse Metropolis, Nigeria, bears rising concerns over water safety and public health. Thirty (30) sachet water samples from ten popular brands were collected and analyzed for pH, turbidity, electrical conductivity (EC), total dissolved solids (TDS), total hardness, nitrite, chloride, and calcium concentration. All results showed that physicochemical parameters were within the limits set by the World Health Organization (WHO) and National Standard for Drinking Water Quality (NSDWQ). As noted, pH value was between 6.81 and 7.41, while turbidity was under the WHO suggested maximum of 5 NTU. Microbiological examination indicated the complete absence of total coliforms, Escherichia coli, and total bacterial count which shows good purification methods were applied. However, lack of heavy metal analysis poses a risk due to possible pollution from industrial effluents and agricultural runoff. The study still highlights the need for persistent surveillance and peri-regulation to warrant the safety of sachet water, primarily in metropolitan areas where the public water supply is deficient, while region possesses some encouraging findings. The results aim to assist stakeholders in evaluation assessment of sachet water while emphasizing the dire need to safeguard public health and safety.
