Rivers are important to civilization because river water can be diverted for agricultural irrigation, industry, hygiene, and related uses. Most rivers have varied hydrological characteristics like water depth, flow rate ...
Physico-chemical assessment of the Jalaur River system, Iloilo, Philippines
(Silliman University, 2010-01)
The Jalaur River System was studied for the quality of its water because water quality is a significant and powerful determinant of the health of aquatic ecosystems. This study aimed at investigating the physico-chemical parameters, nutrient load, heavy metal concentrations and pesticide residues of the Jalaur River system. One of the purposes of this study was to develop a database on the seasonal changes in these river characteristics.
Quantitative samples of water, sediments, algae and fish were collected and analyzed during the rainy season (July-September 2009) and the dry season (January-March 2010) from five sampling stations representing upstream, midstream and downstream sections of the 123-kilometer long river. Based on the water quality standard and water classification adopted by the DENR, the Jalaur River stretch can be classified as class C and D. Class C water is for propagation and growth of aquatic resources while class D water is for agriculture, irrigation, livestock watering, and industrial cooling and processing.
The detected levels of metal contamination, mainly Cr, and Pb, in sediments of Jalaur River were found to exceed the geochemical background or threshold levels. Lead and chromium were also detected in filamentous algae (lumot), Azolla, and tilapia (Oreochromis niloticus) sampled at Moroboro sampling site. No organochlorines, organophosphates, carbamates, and pyrethroids pesticides were detected at the detection limit of the analyses for both water and sediment samples.
The deterioration in the physico-chemical quality and rise in the nutrient levels observed in this study is alarming, and periodic monitoring and preventive measures are required to save the aquatic system of eutrophication. Heavy metal contamination of bottom sediments, algae and fish samples is also a cause for alarm because these heavy metals pose threats to human health. The finidngs have important implications for the development of effective water management strategies and as guide to remediation of efforts for the Jalaur River system....

Medicinal and phytochemical properties of selected herbal plants in Central China and Western Visayas, Philippines
(United Federation of Fil-Am Educators, Inc., 2021-11)
This investigation was conducted to evaluate the medicinal and phytochemical properties of four selected herbal plants: Andrographis paniculata, Cassia obtusifolia, Leonurus japonicus and Pueraria lobata found in both Central China and Western Visayas, Philippines. Mixed method research design was employed, the quantitative on herbals' descriptions and phytochemical analysis, while qualitative on interview of traditional healers. The herbals were identified and authenticated by the research team. The phytochemical analyses used the methods: Extraction of plant parts, Thin Layer Chromatography, UV identification and High-Performance Liquid Chromatography. The bioactive compounds diterpenoid dehydroangropholide in A. paniculata supports the claim of local healers to treat stomach ache and diabetes; the terpenoid orange cassia and chrysophanol in C. obtusifolia seeds supports the treatment for ulcer, hepatitis or liver associated ailment, ringworm, scabies and psoriasis; the alkaloid leonurine hydrochloride in L. japonicus leaves supports the healing practices in treating menstrual disorders and fever; and the flavonoid puerarin in P. lobata tubers supports the claim of traditional healers in regulating menstruation, diuresis, fever and promotes blood circulation. Most healing practices in both study areas have scientific explanations....
Vibrio load and percentage composition of sucrose-fermenting vibrios in Nile tilapia (Oreochromis niloticus) cultured in brackish water earthen ponds and biocontrol potential of recycled tilapia-conditioned greenwater against population growth of V. parahaemolyticus and non-sucrose-fermenting vibrios in the grow-out culture of white leg shrimp (Litopenaeus vannamei)
(Wiley, 2022-10-20)
<i>Vibrio</i> are known opportunistic pathogens of pond-cultured fish and shrimp. This study determined the presumptive <i>Vibrio</i> count (PVC) and percentage composition of “beneficial” sucrose-fermenting vibrios (SFVs) ...
