Are There Nano- and Microplastics in the Workplace?

The growing problem of plastic pollution in the environment is receiving an increasing amount of attention (see article in Nature). Small particles of plastics are often referred to as microplastics (plastic particles smaller than 5 mm [1]) and nanoplastics (the nanoscale fraction of plastic particles). Nano- and microplastic particles (NMPPs) can be formed through environmental Read More >

Potential Hazards of Additive Manufacturing

Additive manufacturing (AM), commonly referred to as 3-D printing, is becoming more prevalent in industry. AM is a set of processes for making products by selectively joining small amounts of material, using a computer-aided design file. [1,2] The advantages for industry include: shortened production cycles, reduced tooling costs, reduced waste material, easier product customization, novel Read More >
