排出大海的塑膠，經過紫外線、物理或者生物分解的作用等，將會拆解成為微形塑膠粒。1389Please respect copyright.ＰＥＮＡＮＡuKKH0Omiuq

如圖中所示，被分解的膠粒將依據其體積大細，而被賦上不同的命名。1389Please respect copyright.ＰＥＮＡＮＡDwvDWmKmsf

(圖2)箭嘴所指的為3μm的microplastic，可以見得到microplastic會黏在細胞的表面，同時細胞亦有能力將microplastic吞進內部。1389Please respect copyright.ＰＥＮＡＮＡg6IlZmDXGz

(圖3)塑膠粒體積過大的話，細胞便無法把它吞進內部。1389Please respect copyright.ＰＥＮＡＮＡGLVvxjOABe
1389Please respect copyright.ＰＥＮＡＮＡ1ARd6AxtZ9
但是，如圖中所示，若某特定會被細胞外部接收器吸收的物質黏附在體積相對為大的塑膠粒表面，大型塑膠粒便能經由細胞接收器輔助進入體內。1389Please respect copyright.ＰＥＮＡＮＡPptgkKMma0

(圖4)科學家證實(Ref2)，對比浸在乾淨水裡，浸在淡/鹹水4星期的塑膠粒將更有效率進入細胞內部，而淡水及鹹水兩者對塑膠粒的影響則為相約。1389Please respect copyright.ＰＥＮＡＮＡNjdwKZjQOk
1389Please respect copyright.ＰＥＮＡＮＡW4hwO7oqFC
這相信是因為水裡不同的物質黏附在塑膠粒表面上，從而輔助塑膠粒進入細胞內。1389Please respect copyright.ＰＥＮＡＮＡu04BXgdCY1
1389Please respect copyright.ＰＥＮＡＮＡYokWVX2faa
而乾淨水並無外來物質，因此沒能輔助塑膠粒進入細胞內部，故比浸在淡/鹹水4星期的塑膠粒較為遜色。1389Please respect copyright.ＰＥＮＡＮＡ8g0CX8Ndd1

(圖5)現實中，被分解的膠粒在大海中會遇上各種外來物質，形成名為Ecocorona的外膜。1389Please respect copyright.ＰＥＮＡＮＡKJ1tonK9a0
1389Please respect copyright.ＰＥＮＡＮＡ4VNAn0xscU
1389Please respect copyright.ＰＥＮＡＮＡSIRJiNnD3O
與體積相同的塑膠粒作對比，擁有Ecocorona外膜的塑膠粒會比工業原始出產版本的塑膠粒更有效率進入人體細胞內部(Ref1)。1389Please respect copyright.ＰＥＮＡＮＡB9oL79N4JA
1389Please respect copyright.ＰＥＮＡＮＡOXGOb9aptP
由此可見，長期攝取排放在海洋中的塑膠粒對身體的影響究竟會有多大這話題，絕對值得作深入的研究和檢討。1389Please respect copyright.ＰＥＮＡＮＡcLJNGtm75H
