The paper opened an entire research field. Since then, more than 7,000 published studies have shown the prevalence of microplastics in the environment, in wildlife and in the human body.
So what have we learned? In a paper released today, an international group of experts, including myself, summarize the current state of knowledge.
In short, microplastics are widespread, accumulating in the remotest parts of our planet. There is evidence of their toxic effects at every level of biological organization, from tiny insects at the bottom of the food chain to apex predators.
Microplastics are pervasive in food and drink and have been detected throughout the human body. Evidence of their harmful effects is emerging.
