For the past years, it became a serious environmental issue in Manila Bay. This occurrence is continuously degrading its ecological integrity and causing major changes in its community structure and production. Thus, a deeper understanding of the dynamics of excessive nutrient fluxes in the bay is important in establishing management practices for the recovery of its ecosystem. In this study, more recent field surveys and time-series analyses were done (i) to document the current state of nutrient pollution in Manila Bay from January 2017- November 2018, and (ii) to determine the significant trends of eutrophication from 2012 to present.

The aim of this study is to determine the contamination rate of soil-transmitted helminths (STH) on soils sampled from elementary schools in Lucban, Quezon, Philippines. The soil samples were randomly selected and were processed by sucrose-floatation technique. Results show that, out of 384 soil samples, 177 (46.09%) were found to be contaminated with soil-transmitted helminths (STH). Among the parasites observed, Toxocara sp. (24.48%) had the highest contamination rate while Hymenolepis sp. (0.52%) was the least prevalent. However, the contamination rate and mean density showed no significant difference (p=0.127). Moreover, correlation analysis suggests that STH eggs were prevalent in soils with high moisture content, high soil temperature, basic, and silty soil texture. These results reveal the extent of soil contamination from elementary schools in Lucban, Quezon, Philippines is relatively high; hence, it is hoped that this study will raise public awareness for the development of management practices and prevention strategies regarding parasite contamination in soil.
