In October 2023, global chemical experts from around the world gathered in Rome to attend the Persistent Organic Pollutants Review Committee under the Stockholm Convention. They concluded that chlorpyrifos, owing to its long-range environmental transport, could give rise to serious adverse effects on human health and/or the environment, thereby necessitating global action.

Just one week before this decision was announced, experts from 31 countries unanimously concluded that chlorpyrifos meets the criteria set forth in the Rotterdam Convention, owing to the risks it poses to human health. The Rotterdam Convention empowers its 165 Parties to make informed decisions regarding the future import of pesticides. Both decisions will be submitted to the Conference of the Parties in 2025.

At this week’s meeting of the Persistent Organic Pollutants Review Committee in Rome, experts from 31 countries and five regions recommended advancing chlorpyrifos to the risk management evaluation stage under Annex F of the Stockholm Convention. This decision was driven by concerns about the risks posed by chlorpyrifos to human health and the environment.

This marks another step toward listing chlorpyrifos under the Stockholm Convention, which sets global bans on persistent organic pollutants (POPs).

The initial negotiations for the Stockholm Convention concluded in Stockholm, with all countries having completed the treaty’s negotiation and deliberation. On May 17, 2004, the original 128 parties and 151 signatory states had ratified the convention, bringing it into formal effect. The parties jointly agreed to ban nine persistent organic pollutants. The convention also provides for the review and amendment of its provisions should new chemicals meet specified criteria regarding persistence and transboundary risks.

On May 8, 2009, at the Convention’s Conference in Geneva, a new batch of chemicals was added to the Convention’s list of controlled substances.

China has acceded to the Stockholm Convention on Persistent Organic Pollutants. In 2004, China formally became a Party to the Convention, thereby committing itself to comply with its provisions and to take measures to reduce and control the production, use, release, and dissemination of persistent organic pollutants (POPs). This means that China has fulfilled its international obligations related to POPs within the framework of global cooperation, thereby protecting the environment and human health from the harmful effects of these substances.

At present, chlorpyrifos is prohibited for use on vegetables in China; once this pesticide is listed under the Convention, its scope of application in our country could be further restricted.

At present, China still has 1,127 registered pesticide formulations containing chlorpyrifos. In terms of both the number of registrations and sales volume, chlorpyrifos remains a flagship product for many companies. It is imperative to promptly adjust product portfolios and proactively plan for alternative solutions.
