The dumping of nuclear-contaminated wastewater from the Fukushima nuclear power plant in Japan has raised concerns among Chinese citizens about the state of the marine environment. Chinese environmental authorities on Monday vowed to strengthen the monitoring of marine environmental pollution through multiple means, including conducting baseline surveys of marine pollution and utilizing satellites for monitoring.

China has launched its third marine pollution baseline survey, with the goal of completing a thorough investigation and assessment by 2025, said Wang Juying, the director of the National Marine Environmental Monitoring Center, at the ministry's monthly press conference on Monday.

According to Wang, this survey follows the overall approach of "understanding the current situation, identifying problems, analyzing causes, and proposing countermeasures," and focuses on China's coastal waters and the country's 283 bays, with the aim of understanding the baseline levels of various pollutants in China's jurisdictional waters, the ecological conditions of various bays, and the impact of human activities. 

"The survey aims to comprehensively grasp the basic state and trends of the marine ecological environment," Wang said.

China previously conducted the first and second national marine pollution baseline surveys in 1976 and 1996, respectively.

Hu Songqin, deputy director of the Department of Marine Ecology and Environment of the Ministry of Ecology and Environment, mentioned during the conference that the recent successful launch of a satellite to serve environmental protection and disaster management will significantly enhance data support and emergency response capabilities for sudden water environmental pollution events.

She stated that the Ministry of Ecology and Environment will actively collaborate with relevant research institutions and coastal regions, making effective use of data sources from monitoring systems. 

"These will provide crucial technical support for addressing sudden environmental events, pollution incidents, investigations of key risk sources, and enhancing marine ecological environmental governance capabilities," she noted.

In response to Japan dumping the contaminated water from the Fukushima nuclear plant into the ocean, the Ministry of Ecology and Environment has stated the specific measures that China has taken in terms of marine radiation environment monitoring.

At present, the ministry is actively conducting marine radiation environment monitoring in areas under China's jurisdiction for the year 2023, guided by a focus on critical regions, comprehensive coverage of jurisdictional waters, and a thorough understanding of key pathways, according to the ministry.

The ministry also vowed that in the future it will continue to strengthen relevant monitoring efforts, closely track and assess the potential impact of of contaminated water from the Fukushima nuclear plant on China's marine environment, and effectively safeguard the national interests and public health.

In 2021 and 2022, the ministry organized marine radiation environment monitoring in areas under China's jurisdiction, which provided insight into the baseline condition of the marine radiation environment in these regions. The monitoring results indicated that there were no abnormal levels of artificial radioactive isotopes in the seawater and marine organisms in China's jurisdictional waters, and overall, the concentrations remained within the historical fluctuation range.
