Due to its ubiquitous presence in the environment and lack of a scientific consensus regarding environmental safety widely used anionic surfactant Sodium Lauryl Sulfate (CAS No: 151-21-3), systematic literature review thematic analysis was conducted. All studies about sodium lauryl sulfate (SLS) key databases were reviewed, with coding methods identify impact categories from SLS exposure without potential narration bias. Based on limited number SLS, there is empirical evidence this...
Abstract Recent studies suggest per‐ and polyfluoroalkyl substances (PFAS) are ubiquitous in rivers worldwide. In the Asia‐Pacific region, frequency of PFAS detection is increasing. However, overwhelming majority data represent high population urbanized river catchments. this study, we investigate occurrence major Philippines systems characterized by both low densities. Pasig Laguna de Bay River, which drains a urban conurbation, detected at concentrations typical global rivers....
We estimated inflow rates of perfluorooctanesulfonate (PFOS) and perfluorooctanoate (PFOA) to Tokyo Bay, Japan, between February 2004 2011 by a receptor-oriented approach based on quarterly samplings the bay water. Temporal trends in these are an important basis for evaluating changes PFOS PFOA emissions Bay catchment basin. A mixing model average concentrations compounds freshwater bay, which were then multiplied obtain compounds. The enabled us comprehensively cover including via direct...
Road dust samples around human settlements nearby mining areas in Carrascal, Surigao del Sur, Philippines were investigated to quantify the levels of chromium (Cr), nickel (Ni), manganese (Mn) and zinc (Zn) assess potential health risks from selected heavy metals.Metal concentrations road analyzed using Energy Dispersive X-ray Fluorescence (EDXRF) spectrometer.Analytical results showed that average Cr, Ni, Mn, Zn very high at 15,668, 14,814, 7,054, 684 mg/kg, respectively.Measured exceeded...
Climate variability is one of the factors that directly and greatly affect cropping system plant yield. It therefore very important to obtain a good understanding about climate or changes in effect these clearly understand vulnerability food crops as well its agronomic impacts for us create implement adaptive strategies mitigate negative effects. This study assessed rice crop yield both irrigated rainfed ecotype farming Nueva Ecija Province Philippines using semi-annual data different...
The municipality of Mogpog in the Philippines was one severely hit areas during 1993 mining disaster province Marinduque. After three (3) decades, aftermath still lingers and even whole province. This study conducted to assess relationship between social demographics residents their knowledge about heavy metal (HM) pollution its associated health risks. A cross-sectional survey among 314 Mogpog. Six (6) were considered, such as age, sex, marital status, highest education attainment, monthly...
The alarming presence of COVID-19 challenged the United Nations’ (UN) Sustainable Development Goal 2 and made World Health Organization (WHO) declare a public health emergency international concern. Imposed lockdowns disrupted supply demand chain food systems, hence affecting security. This research would like to know assess early effect (two months after lockdown) enhanced community quarantine on security in Philippines. An online survey was employed participated by 331 household...
Lack of studies in developing countries with tropical climate such as the Philippines limit local LID adoption. This study compared performance different scenarios across urban land use types at sub-catchment level using peak flow, runoff volume and flood reductions criteria. Results showed that most effective strategies for each are: 1) combined green roof bioretention low-density residential; 2) high-density 3) rain barrel, permeable pavement industrial, 4) vegetative swale detention pond...
