Photopolymers used for 3D printing are one of several polymeric materials on the consumer goods market containing large amounts of antimony. Photopolymers utilize antimony as a photoinitiator in the polymerization reaction. Antimony is a toxic heavy metal whose environmental concentration and atmospheric flux has recently been found to be increasing. With the projected growth in the 3D printing industry, the health and safety aspects associated with antimony - containing photopolymers and the safe disposal of 3D - printed models are a concern. The antimony content of three different types of polymeric materials (photopolymers, polyethylene, and brake pads) is compared. Leaching tests were conducted on photopolymers used for stereolithographic 3D printing. These epoxy resins contain up to 10 % by weight antimony compounds. Results indicate that up to 3 % of the total antimony contained in the material may be leached over the standard test duration of 20 hours.

"This study investigates the potential impacts of rapid prototyping systems on the health and safety of operators and the environment, a growing concern given its wide-spread use in industry and academia. Materials, processing, and equipment features were used to identify potential health and safety risks and hazards, as well as environmental effects. The study concludes with a ‘best practices’ guide for rapid prototyping laboratories and service bureaus.

Minecraft is a multiplayer sandbox video game based in a virtual world modeled on the real world. Players are able to build and craft everyday items using blocks, the cubic geometry of Minecraft lends itself to the teaching of various academic subjects. Minecraft also has a functioning ecology, with chemistry and physics aspects interwoven within the game that can be used to develop the scientific literacy of players. Here I describe various key scientific and mathematical concepts that are able to be modeled with the game for use in the classroom.

Direct measurements of radionuclide tracers are useful tools for
correcting proxy fluxes that are subject to post depositional changes. An analytical methodology was designed for the measurement of 210Pb and 7Be in rainwater. Atmospheric inputs of the radionuclides to Cumbria (UK) were recorded. Rainwater fluxes were then compared with measurements from soil cores. The annual deposition from April 1997 to March 1998 of 210Pb and 7Be was 165 ± 8 Bq m–2 and 3912 ± 120 Bq m–2, respectively, compared to an indirect 210Pb flux of 148 ± 7 Bq m–2 yr–1 calculated from soil core records.
