Testing the Aquatic Degradation of a 'Domestic Herbicide' That Only Kills Weeds

[Asia Economy Reporter Junho Hwang] Domestic researchers have revealed how the domestically produced herbicide 'Metiozolin,' which selectively kills only weeds, decomposes and acts when it flows into rivers or streams through a self-developed testing device. It is expected that this will enable behavioral evaluation of various chemical substances in the future.

The Safety Evaluation Research Institute team announced on the 19th that they conducted an aquatic sediment metabolism test of Metiozolin to confirm the effects of pesticide components' aquatic exposure and the formation of metabolites as required by the US EPA. The aquatic sediment metabolism test is a test to determine how the herbicide decomposes in water.

Metiozolin accumulated very rapidly in water and was decomposed into carbon dioxide and methane by microorganisms. The main metabolites were found in the sediment, while other metabolites evaporated into the atmosphere.

The Safety Evaluation Research Institute contributed to the registration of Metiozolin with the US EPA and its entry into the US market through these research results.

For this investigation, the Safety Evaluation Research Institute utilized its proprietary technology, the 'Aerobic and Anaerobic Soil Metabolism Testing Device.' This device allows aquatic sediment metabolism tests to be conducted under conditions very similar to natural environments.

Metiozolin is a herbicide that can be used on various lawns such as golf courses, soccer fields, and home gardens. It selectively removes only the target grass called 'Saepoa-pul,' which acts as a host for pathogens that cause turf diseases.

Seo Jongsu, head of the Gyeongnam branch, stated, "The metabolism testing device and research methods used in this study will greatly help clarify the environmental impact of various chemical substances that are emerging as major issues in the environment in the future."
