    Beluso, Heziel F.; Buaron, Michelle Jane A.; Hubag, Angelie Rose C.; Macahilo, Judeilan A.; Mationg, Mary Lorraine S.; Nismal, Myles C.; Pido,Dianah D.; Simaurio, Geraldine C.; Sodusta, Valerie Joy M.; Yasa, Kutch V. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2007-03)
    This research study is a cross-sectional survey done among 90 conveniently selected residents of Brgy. Tabat Tubungan, Iloilo in order to determine the acceptability of the newly-formulated food recipes based on sensory analysis (appearance, smell, taste and texture), general acceptability, cost, and food action response. The ingredients used in each of the three new recipes namely tortang malunggay, alugbati-squash ukoy and Palawan delight are nutritious, cheap and indigenous to the community. The acceptability test was done among the three selected age groups: school-age children (6-12 yrs old), adolescents (13-19 yrs old) and adult (20-40 yrs old). Pre-tested structured questionnaires were used in the evaluation of the acceptability of the three recipes. Results were analyzed using frequency distribution and test of proportion to determine whether or not the prepared recipes are acceptable. Chi-square analysis was used to test the independence of acceptability of the food items based on the set criteria and the age group categories of the panelists. The results show that three newly formulated recipes namely tortang malunggay, alugbati-squash ukoy and Palawan delight were found to contain high amount of energy content (107 kcal, 181 kcal and 160 kcal) and essential nutrients such as vitamins A and C, calcium and iron which are needed and vital to the body. The percent Recommended Dietary Allowance requirements derived from the three newly formulated food recipes were 5.35% of the total caloric need per serving for the tortang malunggay, alugbati-squash ukoy and palawan delight could supply 9.05% and 8.00% of the total caloric needs. For the sensory test, results show that in terms of the appearance, the three recipes: tortang malunggay, alugbati-squash ukoy and Palawan delight are acceptable to 82.22%, 95.56%, and 84.44% of the panelists respectively. Smell of the three recipes is acceptable to 87.78% of the panelists. Among the ninety panelists, 87.78% and 83.33% said that the taste of the food recipes is acceptable. In terms of texture, tortang malunggay received the highest acceptance level of 88.89%. Based on general acceptability, Palawan delight was liked by 93.33% panelist. The computed Chi-square values show that the acceptability based on sensory analysis and general acceptability of the three food recipes (except the taste of alugbati-squash ukoy) is not dependent on the age group category of the panelists. The costs of the three recipes were also acceptable to 95.56% of the panelists. As to the food action-response, 95.56% expressed a favorable response. Because of the positive results obtained during the acceptability test on the three food items, the researchers recommend these recipes be included in Food Supplementation and Nutrition Education activities.

    Gross alpha and gross beta radioactivity and heavy metal concentration profiles of well water of the Calahunan dump site, Mandurriao, Iloilo City
    Amarante, Hena Charma; Basquez, Mark Anthony; Brunio, Christian Allan; Dable, Nesel; De la Pena, Pamela-Di; Genterola, Janis; Oredina, Josette Marie; Padayhag, Dave (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2005-03)
    The study aimed to establish presence of radioactivity and concentration of heavy metals specifically lead and chromium in drinking water from wells within one-kilometer radius from the approximated center of the Calahunan dump site. Results showed that four out of twelve wells have positive results fro gross alpha activity and gross beta activity: wells 2A, 2C, 3A, and 3D. Well 2A, 2C and 3D registered alpha activities of 0.54, 0.033 and 0.369 Bq/L respectively while Well 3A registered beta activity of 1.0 Bq/L. Wells 2A and 3D exceeded the radiological limits set by WHO and PNSDW of 0.1 Bq/L for alpha activity and 1.0 Bq/L for beta activity. These wells that are found adjacent to the perimeter fence of the dump site registered alpha activity (wells 2A, 2C and 3D) and beta activity (well 3A). Radiological activities in all other wells sampled registered less than lower limit of detection. For gamma activity, all wells recorded 137- Cs and 134-Cs activity less than the lower limit of detection. For chromium and lead concentration using FAAS, only well 3C has a chromium concentration of 0.0952 ppm and this exceeded the PNSDW standard for chromium in drinking water (0.05 ppm) FAAS has not recorded any value for lead. For chemical constituent analysis using XRF, two wells in zone 1 (LA and IC), have recorded lead concentration of 0.9 and 0.136 ppm, respectively. In zone two, only well 2D registered a lead concentration of 0.248 ppm. In zone 3, well 3C registered a lead concentration of 0.397 ppm. For chromium concentration, only well 2A in zone 2 has a chromium concentration of 1.79 ppm. The spot interview and ocular inspection found out that the following garbage are disposed of indiscriminately tn the dump site: (1) Television picture tubes, (2) Dysfunctional Computer Monitors, (3) Used syringes and needles, (4) Hospital wastes, (5) Automobile batteries and dry cells, (6) scrap iron, tin cans, paint cans, paint cans, etc., (7) polyethylene bottle, glass bottles, and containers of similar types, and (8) other organic and inorganic wastes. Wells whose values for gross alpha, lead, and chromium concentration exceeded the standard are unsuitable for dinking and other domestic uses. The observation that wells (2A and 3D) near the Calahunan dump site registered higher-than-standard alpha activity may be a good basis to conduct further research particularly on the effect of leachate from dump site.

    Physiochemical factors affecting mangrove distribution and occurrence in selected sites in the Province of Antique
    Agapin, Antonio, Jr. D. (Division of Biological Sciences, Bachelor of Science in Biology, University of the Philippines Visayas, 2009-03)
    Mangrove forests are unique inter-tidal ecosystems comprised of taxonomically diverse, salt-tolerant tree and other plant species that are primarily found o.i relatively sheltered coastlines, deltas, estuaries, and lagoons in tropical and subtropical regions of the world. The objective of this study is to generally determine the physicochemical factors influencing the distribution and occurrence of mangroves in selected sites in the Province of Antique and to specifically measure selected physicochemical factors influencing the distribution and occurrence per species per municipality and correlate selected physicochemical factors like soil and water salinity, soil and water pH, and soil and water temperature influencing the distribution and occurrence per species per municipality using Pearson Correlation Coefficient. There were 224 plots established in 11 municipalities in the province of Antique. Twenty-five plots were established in Anini-y, 44 in Hamtic, 11 in San Jose, 5 in Belison, 18 in Patnongon, 23 in Bugasong, 11 in Barbaza, 9 in Tibiao, 26 in Culasi, 23 in Pandan, and 29 in Semirara. A total of 27 true mangrove species belonging to 12 families were found in the 11 municipalities of Antique. The 12 families are Family Avicenniaceae represented by Avicennia alba , Avicennia marina, Avicennia officinales, and Avicennia rumphiana', Family Combretaceae represented by Lumnitzera racemosa and Lumnitzera littorea; Family Euphorbiaceae represented by Excoecaria agallocha; Family Lythraceae represented by Pemphis acidula; Family Meliaceae represented by Xylocarpus granatum and Xylocarpus moluccensis; Family Myrsinaceae represented by Aegiceras coniculatum and Aegiceras floridum; Family Myrtaceae represented by Osbornia octodonta; Family Arecaeae (Palmae) represented by Nypa fruticans; Family Rhizophoraceae represented by Bruguiera cylindrica, Bruguiera gymnorrhiza, Bruguiera sexangula, Ceriops decandra, Ceriops tagal, Rhizophora apiculata, Rhizophora mucronata, and Rhizophora stylosa; Family Rubiaceae represented by Scyphiphora hydrophyllacea; Family Sonneratiaceae presented by Sonneratia alba, Sonneratia caseolaris, Sonneratia ovata; and Family Sterculiaceae represented by Heritiera littoralis. For Soil pH, the highest value of 8.87 was observed in the municipality of Hamtic and the lowest at 6.32 in the municipality of Semirara. Overall mean soil pH was 7.31. For Water pH, the highest value of 8.96 was observed in the municipality of San Jose, and the lowest value of 6.29 in the municipality of Tibiao. Overall mean water pH was 7.23. For salinity, it ranged from 3.1 ppt (Tibiao) to 27.47 (Semirara) and the overall mean was 13.37 ppt For Water Temperature, the highest value of 29.48 °C was observed in Anini-y & the lowest value of 24.74 °C in the municipality of Semirara with an overall mean of 27.40 °C. For Soil Temperature, the highest value of 30.2 °C was observed in the municipality of Belison & the lowest value of 24.97 °C in the municipality of Semirara with an overall mean of 27.50 °C. Among the species present, Aegiceras floridum showed significant correlation with Soil pH (favor low soil pH), water pH ( favor low water pH), salinity ( favor high salinity), soil temperature (favor high soil temperature) and water temperature (low water temperature), A. rumphiana showed significant correlation with water pH (favor low water pH) and soil temperature ( favor low soil temperature), B. cylindrica showed significant correlation with soil pH ( favor high soil pH), C. decandra showed significant correlation with water pH (favor low water pH) and salinity (favor high salinity), L. littorea showed significant correlation with soil pH (favor high soil pH), water pH (favor high water pH), salinity (favor high salinity), soil temperature (favor high soil temperature) and water temperature (favor high water temperature), O. octodonta showed significant correlation with soil pH (favor high soil pH), water pH (favor low water pH), salinity ( favor low salinity), soil temperature (favor high soil temperature) and water temperature (favor low water temperature), S. caseolaris showed significant correlation with water pH (favor low water pH), salinity (favor low salinity), soil temperature (favor low soil temperature) and water temperature (favor low water temperature) and S. ovata showed significant correlation with soil pH ( low soil pH), salinity (favor low salinity) and water temperature (favor low water temperature).
