Occurrence and backtracking of mass loads including tire wear particles in northern Atlantic

Few studies report the occurrence of microplastics (MP), including tire wear particles (TWP) in the marine , and little data is available regarding their size or sources. Here we present active air sampling devices (low- and high-volume samplers) for the evaluation of composition and MP mass loads in the marine . Air was sampled during a research cruise along the Norwegian coast up to Bear Island. Samples were analyzed with pyrolysis-gas chromatography-mass spectrometry, generating a mass-based data set for MP in the marine atmosphere. Here we show the ubiquity of MP, even in remote Arctic areas with concentrations up to 37.5 ng m−3. Cluster of terephthalate (max. 1.5 ng m−3) were universally present. TWP (max. 35 ng m−3) and cluster of , , and (max. 1.1 ng m−3) were also detected. Atmospheric transport and dispersion models, suggested the introduction of MP into the marine atmosphere equally from sea- and land-based emissions, transforming the ocean from a into a for MP.

Myles and his team studied eczema "hot spots" around the country and found that and were the most prevalent chemicals in the environment. These chemicals are used in products, such as adhesives, flexible foams, carpeting and fabrics.

"A new plant-based substitute for polyurethane foam eliminates the health risk of the material, commonly found in insulation, car seats and other types of cushioning, and it’s more environmentally sustainable, our new research shows."
