Sezvatinoziva tose, zvisaririra zvemabhegi epurasitiki zvakapararira kunenge kumativi ose enyika, kubva muguta rine ruzha kusvika kunzvimbo dzisingasvikiki, kune nhamba dzakasvibiswa dzakachena, uye kusvibiswa kunokonzerwa nemabhegi epurasitiki kuri kuramba kuchiwedzera kuipa. Zvinotora mazana emakore kuti mapurasitiki aya adzikise. Izvo zvinodaidzwa kushatisa kungotsiva kuvepo kwediki microplastic. Hukuru hwayo hunogona kusvika kune micron kana kunyange nanometer chiyero, ichigadzira musanganiswa weheterogeneous epurasitiki zvidimbu zvine maumbirwo akasiyana. Kazhinji zvakaoma kutaura nemaziso.
Nekuwedzera kwekuwedzera kwekutarisisa kwevanhu kusvibiswa kwepurasitiki, izwi rekuti "microplastic" rakaonekwawo mukuziva kwevanhu zvakanyanya, uye zvishoma nezvishoma rakakwezva kutarisisa kwemarudzi ese ehupenyu. Saka chii chinonzi microplastics? Zvinowanzotendwa kuti dhayamita iri pasi pe5 mm, kunyanya kubva kune madiki epurasitiki zvidimbu zvakaburitswa zvakananga mukati mezvakatipoteredza uye zvimedu zvepurasitiki zvinogadzirwa nekuparara kwemarara makuru epurasitiki.
Microplastics idiki muhukuru uye inonetsa kuona neziso rakashama, asi kugona kwavo kweadsorption kwakasimba. Kana yasanganiswa nezvinosvibisa zvirimo munzvimbo yegungwa, ichaita nzvimbo yekusvibisa, uye ichayangarara kunzvimbo dzakasiyana siyana dzine mafungu egungwa, zvichiwedzera Kuwedzera huwandu hwekusvibiswa. Nekuda kwekuti dhayamita ye microplastics idiki, inogona kudyiwa nemhuka dziri mugungwa, zvichikanganisa kukura kwavo, kukura nekubereka, uye kukanganisa kuenzana kwehupenyu. Kupinda mumuviri wezvipenyu zvegungwa, uyezve kupinda mumuviri wemunhu kuburikidza neketani yezvokudya, kune simba guru pahutano hwevanhu uye kunotyisidzira hutano hwevanhu.
Nekuti microplastics inotakura tsvina, inozivikanwawo se "PM2.5 mugungwa". Naizvozvo, inonzi zvakare zvakajeka "PM2.5 muindasitiri yepurasitiki".
Kubva muna 2014, microplastics yakanyorwa seimwe yematambudziko gumi ekukurumidzira ezvakatipoteredza. Nekuvandudzwa kwekuziva kwevanhu nezvekuchengetedzwa kwemakungwa uye hutano hwemamiriro ekunze emugungwa, microplastics yave nyaya inopisa mukutsvagisa kwesainzi yegungwa.
Microplastics iri kwese kwese mazuva ano, uye kubva kune akawanda ezvigadzirwa zvemumba zvatinoshandisa, microplastics inogona kupinda mumvura. Inogona kupinda mumhepo inotenderera yezvakatipoteredza, kupinda mugungwa kubva kumafekitari kana mhepo, kana nzizi, kana kupinda mumhepo, umo microplastic particles mumhepo inowira pasi kuburikidza nemamiriro ekunze akadai semvura nechando, uye yobva yapinda muvhu. , kana Iyo rwizi system yakapinda mubiological cycle, uye inozopedzisira yaunzwa muvanhu circulatory system neiyo biological cycle. Vari kwese kwese mumhepo yatinofema, mumvura yatinonwa.
Wandering microplastics inodyiwa nyore neakaderera-magumo echikafu zvisikwa. Microplastics haigone kugayiwa uye inogona kungogara mudumbu nguva dzese, ichitora nzvimbo uye ichikonzera kuti mhuka dzirware kana kufa; zvisikwa zviri pasi pecheni yezvokudya zvichadyiwa nemhuka dzepamusoro-soro. Pamusoro pecheni yekudya ndeye vanhu. Nhamba huru ye microplastics iri mumuviri. Mushure mekudyiwa kwevanhu, izvi zvidiki zvisingagadzike zvinokonzeresa kukuvadza kusingafungidzirwe kuvanhu.
Kuderedza marara epurasitiki uye kumisa kupararira kwemicroplastic ibasa risinganzvengeki rinogovaniswa revanhu.
Mhinduro kune microplastics ndeyekuderedza kana kubvisa kunobva kusvibiswa kubva kune chikonzero, kuramba kushandisa mabhegi epurasitiki ane plastiki, uye usarasa tsvina yepurasitiki kana kupisa; Rasa tsvina nenzira yakabatana uye isina kusvibiswa, kana kuviga zvakadzika; tsigira "plastic ban" uye kuzivisa "plastic ban" dzidzo, kuitira kuti vanhu vagone kungwarira kune microplastics uye mamwe maitiro anokuvadza kune zvakasikwa, uye kunzwisisa kuti vanhu vane hukama hwepedyo nemasikirwo.
Kutanga kubva kumunhu wega wega, kuburikidza nekuedza kwemunhu wega wega, tinokwanisa kuita kuti nharaunda yakasikwa ive yakachena uye kupa hurongwa hwekutenderera kwechisikigo kushanda kwakanaka.
