A new study says that it could be centuries before millions of the classic toys submerged in the Earth's seas disintegrate.
- A new study by researchers from the University of Plymouth estimates that it could be up to 1,300 years before LEGO pieces lost to the sea disintegrate.
- Researchers collected fifty LEGO pieces washed up on beaches in southwest England and compared them to archived blocks in their original condition.
- The classic children's toy is made of an incredibly durable material called acrylonitrile butadiene styrene (ABS), a rock-solid polymer.
Graphene is insanely useful, but very difficult to produce — until now.
- Graphene is a lattice of carbon atoms arranged in a chicken-wire formation, a structure that makes it very useful for a wide range of applications.
- However, it's been very difficult and expensive to make.
- This new technique cuts down on the cost and difficulty by flash heating any carbon-based material, such as used coffee grounds or plastic waste.
A new method of measuring human exposure to the potentially toxic chemical calls into question regulatory policy.
- Bisphenol A, or BPA, is produced at a massive scale in order to manufacture plastics.
- It's been linked to a wide variety of negative health effects, but regulatory agencies have mainly left the chemical alone due to its usefulness and the low exposure levels found in humans.
- However, a new study found that the method that most researchers have used to measure BPA exposure in humans drastically underestimates the actual exposure.
When these particles are eaten by earthworms, the results are not good.
- New research from Anglia Ruskin University states that microplastics in soil are causing earthworms to lose weight.
- Soil affected by microplastics produces less crop yield due to less productive earthworms and lower pH levels.
- If this trend continues, our entire agricultural system could be compromised.
Those silky tea bags might be releasing plastics into your digestive system.
- A new study at McGill University discovered that many tea bags leach billions of plastic particles into every cup.
- While the health dangers are unknown, past research uncovered serious problems in other mammals when consuming such particles.
- Scientists estimate that between five and 13 million metric tons of plastic are dumped into oceans every single year.
