Acknowledgments
We greatly thank late Dr. Yasushi Kurihara, emeritus professor of Tohoku University, who developed the microcosm system first in Japan. All of our studies could not
start without his original investigation. Also we would like to show special thanks to
Dr. Katsura Sugiura, emeritus professor of Sagami Women’s University, for his
kindful teaching and essential discussion for the assessment method of microcosm
examination using P/R ratio through the project of Environment Research and
Technology Development Fund of the Environmental Agency of Japan and the
Japan Chemical Industry Association (JCIA)’s new Long-range Research Initiative
(LRI). Some of the assessment data in this book were cited from Dr. Sugiura’s
published papers. Furthermore, greatly thanks to Dr. Ryuichi Sudo, former professor
of Tohoku University; Dr. Zen-ichiro Kawabata, professor of the Research Institute
for Humanity and Nature; Dr. Shuichi Shikano, associate professor of Tohoku
University; Dr. Shoichi Fuma, senior researcher of the National Institute for Quantum and Radiological Sciences and Technology; Dr. Takashi Amemiya, professor of
Yokohama National University; Dr. Toshiyuki Nakajima, professor of Ehime University; Dr. Tomoaki Itayama, professor of Nagasaki University; and all of the
students and associate researchers who investigated microcosm study with us for
their kindly cooperation and efforts.
The experimental data described in this book are mainly based on “Development
of an Ecosystem Risk Impact Assessment System Using Microcosm (S2-09)”
supported by the Environment Research and Technology Development Fund of
the Environmental Agency of Japan in the Fiscal years 2009–2011, “Development
of an Ecosystem Risk Impact Assessment System Against Chemical Substances
Using Microcosm (2012PT4-02)” supported by the Japan Chemical Industry Association (JCIA)’s new Long-range Research Initiative (LRI) in the Fiscal years 2012–
2014, and Doctoral thesis of Dr. Kazuhito Murakami (Toho University, 1994),
Dr. Nobuyuki Tanaka (Tottori University, 1996), Dr. Yoshie Takamatsu (Tsukuba
University, 1999), Dr. Ken-ichi Shibata (Yokohama National University, 2013), and
Dr. Kunihiko Kakazu (Fukushima University, 2014).
