Standard ready biodegradability tests are conducted at unrealistically high test concentration and therefore cannot properly evaluate toxic substances to microorganisms. The present study evaluated the effects of four adsorbent carriers in modified r

The estimated domestic usage of DD (a typical nematocide) has been the greatest among all the agricultural chemicals in Japan. DD is involved in a document which is used to establish tap water quality standard in Japan. The document indicates that DD

We used Ames assays to investigate the effects of ozonation (designated O3), ozonation followed by chlorination (O3/Cl), an advanced oxidation process (AOP, UV/H2O2), and AOP followed by chlorination (AOP/Cl) on the mutagenicity of solutions of 3-met

Effect of test concentration in the ready biodegradability test for chemical substances: Improvement of OECD test guideline 301C

Autor: Ryosuke Nabeoka, Tomohiko Yoshida, Takashi Kameya, Takakazu Kayashima, Masanori Taruki

Publikováno v: Environmental Toxicology and Chemistry. 35:84-90

In Japan, understanding the environmental persistence of chemicals is very important for risk assessment, and ready biodegradability tests are mainly conducted according to the Organisation for Economic Co-operation and Development Test Guideline 301
