Shanghai Daoqin Plastics Co., Ltd.

         in ring in small 于5mm plastics material by is micro plastics, it has can by 人眼察觉, more more is not only difficult 以凭肉眼 separation 辨, machine very difficult remove.

        土壤 is how by 污染?

        农 film: 我国农 film thick degree relatively thin, has small 于0.005mm, 以至于我国 农 film recycling rate high. in in film separation understanding is plastics sheet/slice is micro plastics, this is micro plastics 进入土壤 important 途径.

         water and 污泥: 约90% micro plastics in water rear 会累积 in in, this micro plastics can can industrial waste water and active use water in plastics fiber, is 常规处理 methods difficult has remove plastics micro 粒.

        生 material separation understanding: 一 食土动 material (蚯蚓) in plastics rear, its system abrasion and 代谢, generate grade micro plastics, or in rear again 次进入食 material in, by belt/tape 入土壤 internal or through type expand dispersion.

         large gas drop: has related data table/sheet 明, in large gas ring in micro plastics year drop rate 以巴黎城市 poly is high 达3~10吨, its in fiber type micro plastics large more 数. large gas drop is formed table/sheet micro plastics causes 之一.

         for effect/influence has more large?

        吸附污染 material and micro material: micro plastics in ring in 扮演 污染 material 迁移载体 角 color, heavy metal, has machine material and other. micro plastics aging separation understanding, formed is material, 致病菌 and has micro material 运输载体, solid in in, for 土壤健康造 formed loss 害.

         make modified: in for material 吸附程 degree increase and micro material reduce upper, in plastics pellets increase 进一步 make material property 质发生改变, 直接反映 is ratio property reduce, 土壤孔隙 degree, hydrophobic water property reinforcement and other issues. comprehensive 起 导致土壤毒 property increase, property 质改变, 营养流失 add fast, 丧失耕 as value.

         for material effect/influence small

        蚯蚓 as is types by as is reaction quality material, is 生态毒理国际 standards in recommendation material types 之一. its for 土壤污染胁迫 敏感程 degree very high, has research table/sheet 明, 当土壤 in micro plastics concentrated degree to 60%时, 蚯蚓 死亡 rate most high, long rate 也出现 negative value.

         in addition micro plastics in low 营养生 material in 积累也会直接 as used for related material in other material, property material more effect/influence.
