Laboratory of Intellectual Fundamentals for Environmental Studies

Profile of Research Sections

Environmental Analytical Chemistry Laboratory

1) Preparation of environmental and analytical reference samples, and long-term storage of environmental samples (specimen banking)

In order to assist in the accurate control of chemical monitoring, we prepare environmental reference samples of mostly residual chemicals in the environment including highly demanded re-preparations. In response to social need, we also prepare and supply reference samples to be used in analyses to the extent possible.

With respect to long-term storage of environmental samples, we continue to collect and store existing samples and data in conjunction with long-term environmental monitoring projects inside and outside the Institute. From the longer and wider perspective, we aim to establish a program for long-term storage of environmental samples.

2) Function as a reference laboratory

We also aim to play the role of the environmental reference laboratory in Japan. In order to achieve this goal, we will (1) review techniques for the control of analytical accuracy and cross-check analytical methods with a view to improvements, and (2) examine various ways to improve the taxonomical identification techniques for microalgae and other test subjects, and maintain, control and supply type strains, reference strains and other strains (stock) with special functions.

Biological Resource Laboratory

1) Search, collection and storage of environmentally useful microorganisms; Establishment of the basic operational infrastructure for the development, breeding and cultivation of biological test species; Storage of cells and genes of endangered wildlife species.

(1) Environmental microorganisms: We have a thousand strains in storage. We expect to expand this collection in future. We will classify the environmental microorganisms and analyze their genetics and useful functions. The resulting data will be developed into a database. We will also develop cryopreservation technology for these samples.

(2) Biological test samples: We will select high quality biological materials through basic research that includes gene analysis, stocking of useful genes, screening and purification, with the objectives of establishing an efficient system for breeding/cultivation and supply of these samples.

(3) Preservation of endangered species: Our objectives are to store somatic cells, reproductive cells and genes of endangered wildlife as well as endangered aquatic plants.

2) Biological Resources Information Network

We are promoting inter-ministry and international cooperation in the collection of information, classification and preservation of biological resources to establish a biological resources information network that extends beyond Japan. In addition to these basic research technologies, we are involved in improvement of the sensitivity and accuracy of environmental sample analysis by the Institute. We are also involved in the management and operations of shared instruments that have supported the development of new analytical techniques.
