Volume 2 Volume 1 This was done through simulation and the comparison of the three land cover scenarios such as land cover, projected land cover and desired land use to determine Read More The study aimed to determine the impact of sound land use management to the runoff in Kabuntalan, Maguindanao in Tamontaka river basin. This was done through simulation and the comparison of the three land cover scenarios such as land cover, projected land cover and desired land use to determine its difference in terms of runoff.

Based on the result, land cover values in runoff volume and peak outflow increase from land cover while decrease in desired land use. There is shorter time to peak in land cover than desired land use. The land cover, represented the land cover without intervention, showed that agriculture will dominate the area with The desired land use represented the sound land use management, showed that there will be This can, however, result to increase in close canopy forest The study showed that desired land use will most likely reduce the magnitude of the flood than the and land covers.

Thus, adopting sound land use management in Tamontaka river basin is crucial to reduce runoff and thereby mitigate flooding in the study area. The technology is also environmentally friendly with the wetlands being habitats for many water birds and other aquatic organisms. Read More The use of constructed wetlands for purifying pre-treated wastewater is a cost effective technology that has been found to be more appropriate for many developing countries. This study assessed nutrient removal efficiency of two floating macrophytes Lemna minor and Azolla pinnata.

The data generated was analyzed using both descriptive and inferential statistics. The significance level was maintained at 0. The results showed that the wastewater physicochemical parameters did not vary during the study period. To the contrary, in all the treatments the concentrations of ammonia, total phosphorous, soluble reactive phosphorous and total nitrogen, decreased over the experimental period. We conclude that the two macrophytes are good for wastewater treatment.

To check this, fresh cattle urine was collected, characterized, diluted and inoculated microalgae species Oscillatoria-SRA Stagnant rainwater algae , Oscillatoria-CWA Cooum waste algae , Chlorella and Synecocystis separately and incubated under fluorescent light with 8 hours light and 16 hours dark cycle. The biomass was quantified after 15 days and found out variation in biomass quantity in all microalgae isolates. The maximum of 2. This study divulged that cattle urine alone is being able to support microalgae growth at a significant amount, thus convalescing industrial production of microalgae ultimately will reduce the cost of microalgal value-added products.

Twenty-two soil samples were collected within the Read More This study aimed to evaluate concentrations of selected heavy metals in the soils of Ilokun dumpsite and adjourning farmlands, and to determine as well levels of heavy metals uptake in various parts of Carica papaya plant collected from the dumpsite. Twenty-two soil samples were collected within the dumpsites and farmlands at depths of cm and cm. Evaluations of heavy metals Ni, Zn, Cd, Cr, Pb and Cu in soil samples and in different parts of Carica papaya plants were carried out using atomic absorption spectrophotometer.

The study revealed higher concentration of Pb in the dumpsite than the farmlands. Mean concentrations of Cd in the dumpsites; 2. Heavy metal uptake was highest in the plant parts compared to the dumpsites and farmlands. Based on the results, the various heavy metal could be classified as slight contaminants Pb, Cr and Ni , moderate contaminants Cu and Cd and severe contaminant Zn. Although concentrations of heavy metals in the farmlands were below the Department of Petroleum Resources and World Health Organisation allowable limits, monitoring the concentration profile of these heavy metals concentrations in the area is recommended to prevent detrimental effects on the environment.

In this study, a field-scale filter bed system was constructed to treat heavy metal Read More The use of amalgamation process to recover gold from mined ores by the small-scale gold miners in the Philippines and other developing countries produces and dispose of untreated wastewater to the receiving water bodies.

In this study, a field-scale filter bed system was constructed to treat heavy metal metal-laden wastewater collected from small-scale gold mining site in Paracale, Camarines Norte, Philippines. The filter bed system was consists of sedimentation tank and filter bed with Cocopeat, a by-product of coconut husk, as adsorbent. Physico-chemical parameters temperature, pH, oxidation-reduction potential, electrical conductivity, turbidity, dissolved oxygen, total dissolved solids, salinity, total suspended solids, color and heavy metal As, Ba, Cd, Hg, Pb concentrations were monitored during the 50 days experiment at a flow rate of 40 Liter per hour for 3 hours daily wastewater application.

Significant reduction was achieved on heavy metals; As Measured effluent physico-chemical parameters and heavy metal concentrations were within the respective regulatory limits. Other effluent parameters with strong correlation with total suspended solids such as turbidity and color, though not regulated, were reduced significantly.

All adsorbed heavy metals accumulated in the upper 25 cm of the Cocopeat column in the filter bed.
