Jumping into the future head first, blindfolded, handcuffed, and in darkness

Plastics in the marine environment have become a major concern because of their persistence at sea, and adverse consequences to marine life and potentially human health. Implementing mitigation strategies requires an understanding and quantification of marine plastic sources, taking spatial and temporal variability into account. Here we present a global model of plastic inputs from rivers into oceans based on waste management, population density and hydrological information. Our model is calibrated against measurements available in the literature. We estimate that between 1.15 and 2.41 million tonnes of plastic waste currently enters the ocean every year from rivers, with over 74% of emissions occurring between May and October. The top 20 polluting rivers, mostly located in Asia, account for 67% of the global total. The findings of this study provide baseline data for ocean plastic mass balance exercises, and assist in prioritizing future plastic debris monitoring and mitigation strategies. Rivers provide a m

Microplastics and nanoplastics (MNPs) are emerging as a potential risk factor for cardiovascular disease in preclinical studies. Direct evidence that this risk extends to humans is lacking.

Scientists express concern over health impacts, with another study finding particles in arteries

Rivers are a major source of plastic waste in the oceans. We estimate that 1000 rivers, are accountable for nearly 80% of global annual riverine plastic emissions, which range between 0.8 – 2.7 million metric tons per year, with small urban rivers amongst the most polluting.

This report examines the economic and business models needed to address the impacts of the plastics economy.

When more than one type of pollution gets wrapped up in the same space, the result can be pretty darn yucky—not to mention dangerous. And the gobs scientists discovered recently on the beaches of the typically picturesque Canary Islands certainly fits the bill.

Microplastics are deposited in river floodplains and carried down to deeper levels, according to a study published in the journal Science of the Total Environment. Local topography, frequency of floods, and soil characteristics can affect the amount of plastic particles that are deposited and potentially carried into deeper soil.

En mars 2022, des scientifiques ont confirmé pour la première fois avoir trouvé des microplastiques dans le sang humain. Ces minuscules fragments se trouvaient dans 80 % des 22 personnes testées - qui étaient des membres ordinaires et anonymes du public. L'échantillon était de petite taille et il n'y a pas encore eu de confirmation explicite que leur présence cause un préjudice direct à la santé humaine, mais avec plus d’études, le temps le dira. Les microplastiques font l'objet d'un examen approfondi. Partout où nous les cherchons, nous les trouvons.
