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. in recent years micro plastics issues frequency frequency 爆出, large gas, in full world flow, micro plastics 几乎遍布 球 各 角落. front about/regarding micro plastics issues full world 关注, however and for about/regarding micro plastics issues hot degree can and ratio 肩.

        实际 upper, micro plastics in in belt/tape 危害远 ratio 我们想象 严 heavy. in micro plastics already 经令人 type generate machine 感, front has research 者指出, upper in micro plastics can can is 海洋 4~23倍, especially is use 土, upper year toward use in micro plastics already ultra- toward in 输出 总 amount.

         that micro plastics is how to 进入土壤? also generate how to 危害呢?

         micro plastics 污染土壤 途径

        农 film 污染: 我国 is production large 国, for use plastics film use amount is high lower. 据悉, 仅2015 year, 我国农 film use amount to 260.36 10,000 tons, to world amount 90%. is upper, 我国农 film product structure combined 理, high film 仅占农 film amount 2%, in to 20%, lower 78%都 is low film market. 发达国家 requirements film thick degree in 0.02mm above, 我国农 film thick degree relatively thin, has small 于0.005mm. this series factors 也导致 农 film easy aging, easy and other issues, 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 污泥污染: according to table/sheet 明, 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. in addition water through 灌溉, 渗透以 and table/sheet 径流也会 will micro plastics belt/tape 入土壤 in, therefore through water 排放灌溉 or 经 预处理 污泥肥 material and 土壤, is 导致土壤 micro plastics increase 元凶.

        生 material separation understanding 污染: 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 污染: according to front 报道, in 阿尔卑斯山, and other in its in plastics micro 粒, 科研人员 table/sheet micro plastics can large gas ring 流进行跨 区 property 转移. but also 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.

         has machine 肥污染: 此 front 曾曝出 about/regarding outer has machine in plastics 污染 情况, its for/regarding 0.5mm above plastics sheet/slice content 展开 调查发现 has machine in in less can plastics sheet/slice, although about/regarding more small micro plastics testing 案例不足, is can 推测出也会 has micro plastics in. long use has machine 肥, 也会造 formed in micro plastics increase more.

         micro plastics for 土壤造 formed 危害

        吸附污染 material and micro material: 学者普遍认 is 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.

         effect/influence 土壤生 material more property: plastics in has agent in degradation process in 进入土壤, make in micro material more property decline, 导致土壤 and material 间 营养交换受 retardant, heavy 者甚至改变陆 生态 system function.

        改变土壤 property 质: 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.

        土壤 micro plastics for material 危害

        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.

         micro plastics has material in through solvent and other function can can to in, material absorption rear can can in its internal generate property 积累. although material can will material in its 子实体(果实)之 outer, is in and type material table/sheet inner heavy metal in 此积累.
