most 近, outer machine 构 一项调查发现, in waste plastics ratio less, is 原先估计数400万 to 1200 10,000 tons 1/10. plastics degradation cycle generally is 200 year 至400 year, that waste plastics to 底 哪儿 呢?

China large 学海洋生命学院生态毒理学教授汝 less 国团队近 day in front 沿期刊《 ring 境污染》发 table/sheet its micro plastics research formed 果, related 结果显示: plastics in short time inner difficult degradation.

汝 less 国告诉科技 day 报记者, year from 陆 排入海洋 plastics waste has 600—1200 10,000 tons, this plastics sheet/slice in ring in 会逐渐裂 understanding is small 于5 mm micro plastics. this micro plastics chemical property stability, in ring in can in year 至几千 year, through 洋流, force 进行远距离迁移, 遍布整 海洋. this micro plastics easy by 海洋生 material 摄入体 inner, through material 网传递 effect/influence 整 海洋生态 system. 当然, this type of effect/influence is bad property.

他们 research also table/sheet 明, micro plastics tool has very large ratio surface 积, easy has has material 质, for 海洋生 material formed combined property 效应.

不, is has research 者都赞 formed “海洋 plastics difficult degradation ” 观点. 夏威夷 large research 人员罗伊尔曾 in water in plastics sheet/slice, will this sheet/slice in cationic light lower can separation understanding formed oxidation carbon, and ethylene and other gas 体. is, plastics separation understanding by active, make light day it 们也会继续 degradation.

in 科院理化 engineering plastics engineering research in is inner most high water polymer/macromolecule material research and industry 化基 之一, in inner 首先开展 海 water degradation material research. through more experiment/testing comparison, high grade engineering 师王格侠发现, in and in has good material degradation property can material, in water in degradation speed rate 不尽如人意.

寻根究底, 王格侠发现 答案: “ polyester material process is micro material function lower hydrolysis reaction;而海 water temperature degree low, property micro material types type less amount less, very difficult tool material degradation conditions, large more polyester material in water in degradation cycle non slow, difficult degradation. ”

“海洋 plastics waste in 2015 year 至2025 year between increase 3倍. ” this is UK ring 境部首席科学家博伊德 in “ front property future report ” in expected. that 么, this formed increase plastics 会 往哪里?答案之一 can can is various 各样鱼 type 肚子里.

当 plastics by “吃”进 鱼肚, it difficult 以像普通食 material by 消化, is formed 毒, deep effect/influence type 身体发育.

自2017 year 以, less 国团队 from micro plastics 污染调查 and material property 两方面开展 related research. ratio in material property 方面, 他们发现 micro plastics not only loss water 青鳉肠道, 鳃, property and other structure and oxidation anti system, also dry type and 子代 发育, 首次证实 micro plastics tool has inner separation dry 扰效应.

another, 他们发现 high concentrated degree micro plastics in water 青鳉卵 housing/shell upper 蓄积, dry 扰胚胎 and 早期仔鱼 发育;他们 联 combined 暴露实验发现 low concentrated degree micro plastics through reduce property has machine material ——菲 in inner material amount, low for water 青鳉 早期发育毒 property.

汝 less 国团队 this important 发现, is evaluation micro plastics 生态风险 provide important 参考. 而王格侠 and formed formed 功走出 difficult degradation 困境. from separation design and versus combined formed 出发, through polymer combined formed modified and blending modified types methods, toward material degradation polyester system in non hydrolysis 基团, achieve material in water in overall can degradation.
