Kodi Microplastic ndi chiyani? Kuwonongeka kwa Microplastic ndi Kuipitsa

Tonse timagwiritsa ntchito pulasitiki tsiku lililonse. Pulasitiki nthawi zambiri sakhala mu mawonekedwe owonongeka. M’kupita kwa nthaŵi, imaphwanyidwa kukhala tizidutswa ting’onoting’ono totchedwa microplastics, zomwe zingakhale zovulaza chilengedwe. Kafukufuku waposachedwa akuwonetsa kuti ma microplastic amapezeka muzakudya, makamaka m'zakudya zam'madzi. Ndiye microplastic ndi chiyani, zovulaza zake ndi zotani? Nawa mafunso okhudza izi…

Kodi microplastics ndi chiyani?

Microplastics ndi tiziduswa tating'ono ta pulasitiki topezeka m'chilengedwe. Amatanthauzidwa ngati tinthu tating'onoting'ono ta pulasitiki zosakwana 5 mm m'mimba mwake. Amapangidwa ngati mapulasitiki ang'onoang'ono, monga mikanda yapulasitiki yaying'ono yomwe imawonjezedwa ku mankhwala otsukira mano ndi otulutsa, kapena amapangidwa pamene mapulasitiki akuluakulu amawonongeka m'chilengedwe.

Ma microplastics amapezeka m'nyanja, mitsinje, ndi nthaka. Nthawi zambiri amadyedwa ndi nyama.

Maphunziro angapo m'zaka za m'ma 1970 adayamba kufufuza kuchuluka kwa ma microplastics m'nyanja ndikupeza milingo yayikulu m'nyanja ya Atlantic pafupi ndi gombe la United States.

Chifukwa cha kuchuluka kwa mapulasitiki padziko lapansi masiku ano, m'mitsinje ndi m'nyanja muli pulasitiki yambiri. Pafupifupi matani 8.8 miliyoni a zinyalala zapulasitiki zimalowa m’nyanja chaka chilichonse.

Matani 276.000 a pulasitikiwa akuyandama panyanja pano, ndipo enawo ayenera kuti anamira kapena kuyandama kumtunda.

Kamodzi m'nyanja, ma microplastics amasunthidwa ndi mafunde, machitidwe a mafunde ndi mphepo ndipo amatha kufalikira kumadera onse a zachilengedwe zam'madzi.

Tizigawo ta pulasitiki tikachepa ndikusintha kukhala tinthu tating'onoting'ono tating'onoting'ono, titha kudyedwa mosavuta ndi nyama zakuthengo, vuto lalikulu m'madzi masiku ano.

Kodi kuwonongeka kwa microplastic ndi chiyani?

Ma Microplastics amapezeka kwambiri m'malo osiyanasiyana, ndipo chakudya sichimodzimodzi.

Kafukufuku waposachedwapa adafufuza mitundu 15 ya mchere wa m'nyanja ndipo anapeza 273 microplastic particles pa kilogalamu (600 particles pa kilogalamu) ya mchere.

Magwero ambiri a microplastics muzakudya ndi nsomba. Chifukwa chakuti microplastic imakhala yofala kwambiri m'madzi a m'nyanja, imadyedwa ndi nsomba ndi zamoyo zina za m'nyanja.

Kafukufuku waposachedwapa wasonyeza kuti nsomba zina zimadya pulasitiki monga chakudya, zomwe zingapangitse kuti pakhale mankhwala oopsa omwe amachuluka m'chiwindi cha nsomba.

Kafukufuku wina akusonyeza kuti zamoyo za m’nyanja zakuya zimakhalanso ndi tizilombo tating’onoting’ono tomwe timakhudza ngakhale zamoyo zakutali kwambiri. mussel ndi oyisitara Zamoyo zina zambiri zili pachiwopsezo chachikulu chotenga matenda.

Pakafukufuku waposachedwa, ma mussels ndi oyster omwe amagwidwa kuti adye anthu ali ndi 0.36-0.47 microplastic particles pa gramu, ndipo nkhonoZamveka kuti zimatha kudya ma microplastic particles 11.000 pachaka.

Kodi microplastic imakhudza bwanji thanzi la munthu?

Ngakhale kafukufuku wina wasonyeza kuti ma microplastics amapezeka muzakudya, sizikudziwikabe kuti ndi zotsatira zotani zomwe zingakhale nazo pa thanzi. Pakadali pano, kafukufuku wochepa adawunika momwe ma microplastics amakhudzira thanzi la munthu ndi matenda.

Phthalates, mtundu wa mankhwala omwe amagwiritsidwa ntchito popanga pulasitiki kusinthasintha, apezeka kuti amawonjezera kukula kwa maselo a khansa ya m'mawere.

Kafukufuku waposachedwa adawona zotsatira za ma microplastics mu mbewa za labotale. Akapatsidwa kwa mbewa, microplastics anaunjikana mu chiwindi, impso ndi matumbo ndi kuchuluka mu chiwindi. kupsinjika kwa okosijeni mamolekyu ochuluka. Zinawonjezeranso mlingo wa molekyulu yomwe ingakhale poizoni ku ubongo.

Tinthu tating'onoting'ono, kuphatikiza ma microplastics, awonetsedwa kuti amadutsa m'matumbo kupita m'magazi ndipo amatha kulowa mu ziwalo zina.

Ma microplastics apezekanso mwa anthu. Mu kafukufuku wina, ulusi wa pulasitiki unapezeka mu 87% ya mapapu aumunthu omwe adayesedwa. Ofufuza anena kuti izi zitha kukhala chifukwa cha ma microplastic omwe amapezeka mumlengalenga.

Kafukufuku wina wasonyeza kuti ma microplastic opangidwa ndi mpweya amatha kuchititsa kuti maselo a m'mapapo apange mankhwala opweteka.

Bisphenol A (BPA) ndi imodzi mwa mapulasitiki omwe amawerengedwa kwambiri omwe amapezeka muzakudya. Nthawi zambiri amapezeka m'matumba apulasitiki kapena zosungiramo chakudya ndipo amatha kulowa mu chakudya.

Umboni wina wasonyeza kuti BPA ikhoza kusokoneza mahomoni obereka, makamaka mwa amayi.

Kodi kuwonongeka kwa microplastic ndi chiyani?

• Zimayambitsa kawopsedwe m'matumbo amunthu, mapapo, chiwindi ndi ma cell aubongo.
• Zimawononga nyama zakuthengo zam'madzi komanso zamoyo zosiyanasiyana.
• Zimayambitsa kuipitsa madzi akumwa.
