MOST OF IT COMES FROM CHINA AND THE “GLOBAL SOUTH:” One Of The Biggest Sources Of Mercury In Fish Isn’t What You’d Think. Although “China has been the world’s largest emitter of anthropogenic Hg since 1971. . . . Hg emission hotspots have significantly shifted toward the Global South (Fig. 3b), with Latin America, Africa, South and Southeast Asia experiencing rapid increases (Fig. 3a). In 2021, despite representing only one-fifth of the global economy59, the Global South (excluding China) constituted two-thirds of global emissions.”

No doubt some dumbass deputy mayor in France will blame the U.S. though.
