The Research and Analytical Services Laboratory (RASL) is one of the four research and extension laboratories of the Natural Sciences Research Institute.

In the past 19 years, the RASL has established its capabilities to

  • conduct researches on endocrine disrupting compounds and persistent organic pollutants such as phenolic substances, pesticides, polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs) in various compartments of the Philippine environment (water, sediments and biota),
  • carry out chemical testing using standard, non-standard, and laboratory-developed methods on the determination of toxic metals and organic micropollutants and other chemicals in water, sediments, soils, food and other biological materials, and
  • provide training courses aimed at assisting the manpower development of other chemical laboratories in the country, i.e., to upgrade the technical capabilities of laboratory personnel to do quality chemical analyses.


  • A prominent National Research Center for Persistent Organic Pollutants.
  • An ISO/IEC 17025:2017* accredited chemical laboratory renowned to produce analytical results guaranteed of competence in carrying out chemical testing.


To continue its mandate by contributing to a safer and healthier world by

  • Providing research support and advisory services in the field of environmental and analytical chemistry to graduate students and researchers of the College of Science of the University of the Philippines.
  • Providing extension services, such as training and analytical services, to students and researchers of other schools, government agencies, private institutions, and individuals.
  • Undertaking research on projects focusing in the areas of analytical and environmental chemistry, specifically on the development and/or validation of highly sensitive analytical methods for identification and measurement of various chemical components in environmental and food samples, as well as on the fate and transport of emerging chemical pollutants in the environment.
