Description: Our aim is to categorize the degradation effects of the marine environment on types of plastics known to be prevalent as waste in the environment. Can a plastic's degradation profiles be linked with Ultraviolet radiation dose? Can we quantify the effect of wavelength on plastics degradation through the development of 'Action spectra'? Do these action spectra differ between plastics? Can laboratory weathering of plastics be linked to the observed environmental weathering?

产品描述：我们的目标是对海洋环境对已知作为环境中废物普遍存在的塑料类型的降解影响进行分类。塑料的降解特性是否与紫外线辐射剂量有关？我们能否通过“作用光谱”的发展来量化波长对塑料降解的影响？这些作用光谱在塑料之间是否不同？塑料的实验室老化是否与观察到的环境老化有关？
