Many toys and hobby items are made from polycarbonate parts, like fins, gyro mounts, and flybar locks in radio-controlled helicopters, [18] and transparent LEGO (ABS is used for opaque pieces). [19] Standard polycarbonate resins are not suitable for long term exposure to UV radiation. To overcome this, the primary resin can have UV stabilisers ...
By using data on surface plastic concentration (pieces of plastic per km 2) from 1972 to 1985 (n=60) and 2002–2012 (n=457) within the same plastic accumulation zone, the study found the mean plastic concentration increase between the two sets of data, including a 10-fold increase of 18,160 to 189,800 pieces of plastic per km 2.
