Shin ƙwayoyin abincin sanyaya na ƙwararraka microplastics a cikin abincinmu?

Saboda yaushe ƙwayoyin abincin sanyaya sun samu farin jini tsakanin ƙasar COVID-19, akwatin daidai sun nuna tsorata mai ban mamaki game da samun microplastics a cikin abincinmu. Bincike mai tsanani ya nuna cewa ƙwayoyin nan sun ƙwararraka hanyoyi na plastics, da sababbin hanyoyi ga lafiya ta farko.

Microplastics, shi ne tsirara na plastics wanda yake da tsintsi mai tsanani, da yawa a matakan da ba a iya ganin su ba da idanu, suka samu ne daga sababbin kayayyaki na plastics da suka ƙasa. Su ka iya fita daga sababbin ƙwayoyi, kamar yadda ake amfani da microbeads a wasu kayayyakin tasir rawa. Tsintsi mai tsanani na su ya sa su iya shiga cikin girma da yawa da kuma ƙwararraka abinci.

Binciken ya gaya wa ƙwayoyin sanyaya da ƙwayoyin amfani da kwararraka, duk da su ake amfani da su don tafiya ko adana abinci. Sabuwar bayanai sun nuna cewa ƙwayoyin sanyaya na ƙwararraka microplastics da yawa har da ƙwayoyin amfani da kwararraka. Daga cikin hanyoyin da ake iya bayyana, plastics mai amfani da shi a cikin botul da kuma ƙwayoyin abinci, yake ƙasa guda da yawa, yana haifar da nawa guda da yara daga hanyoyin da ake samu. Tsirara masu yawa sun kasance tsakanin 20 da 49 micrometers, tsintsi mai tsanani da zai iya shiga cikin wasu ƙwayoyin jiki na ƙwararraka.

Yaushe da yake ƙwararraka microplastics yana danganta da girma na ƙwayar. Idan girma ta yi ƙwayar, to, ƙwararraka da kuma ƙasa sun yi ƙwayar, wanda zai sa ƙwararraka hanyoyi. Misali, ƙwayoyin abinci masu girma, da yawa ake amfani da su don abincin da ake kawo, na iya ƙwararraka har da hanyoyi 30 a kowace amfani. Wannan hasashe ya nuna cewa ƙwararraka daga girma na ƙwayar shi ne sababbin hanyar samun microplastics.

Don yin bincike game da tsorata da ƙwararraka a cikin mutane, masana sun yi takaice cewa abinci mai kyau da ake kawo a Korea, wanda yake hawa da miya, da tuwo da kuma abubuwa biyu, zai iya ƙwararraka mutum da hanyoyi 42 na microplastics. A shekara guda, da wasa 1.6 na abincin da ake kawo a kowace mako, wannan ƙwararraka zai yi har da hanyoyi 3,500. Kwanaki masu amfani da kwararraka, da yawa ake amfani da su don kofa, suka ƙara wata sababbi na ƙwararraka. A Korea, har ma ake amfani da kofa da yawa a kwanaki masu amfani da kwararraka, wannan zai iya haifar da hanyoyi 2,500 a kowace shekara da kowace mutum.

Microplastics ba su da amana ba a cikin lafiya. Bincike masu gabata sun nuna cewa su ka iya haifar da tsorata ta oxidative, yunƙurin cututtuka da kuma tsokoki a cikin hormon. Ana iya samun su a cikin tsintsin mutane, wanda ya ƙunƙura tambaya game da yadda suke ƙasa a cikin jiki. Du da cewa an san sababbin hanyoyi ga mutane ba a cikin gaskiya ba, bincike masu ƙasa sun nuna cewa akwatin daidai na iya haifar da tsorata ta neurotoxicity da kuma immunotoxicity.

Ƙwayoyin amfani da kwararraka, kamar su daga stainless steel, ba su da amana ba daga ƙwararraka microplastics, amma ba su da amana ba daga ƙwararraka. Wannan ya kan samu saboda ƙwararraka daga wasu sababbin hanyoyi a lokacin aiki ko a lokacin ƙirar ƙwayoyi. Saboda haka, sabuwar bayanai sun nuna muhimminciyar kwatanta kwalita a dukkan tsarin aiki, har ma a cikin ƙwayoyin da ake ƙirar da su don su yi amfani da kwararraka.

Tsintsi na hanyoyin da ake samu shi ne wata sababbi na tsorata. Microplastics masu tsintsi 20 da 99 micrometers, wanda suke ƙasa 72% daga cikin hanyoyin da ake samu, su ne masu tsanani da zai iya shiga cikin wasu ƙwayoyin jiki. Wasu masana suka yi tsorata game da samun nanoplastics, hanyoyi masu tsanani da zai iya fita daga hanyoyin bincike da ake amfani a yaushe.

A Korea, har ma ake kawo abinci a yaushe, wannan ƙwararraka ta microplastics zai iya haifar da sababbin hanyoyi a tsakanin shekara. Bayanai sun nuna cewa ƙwayoyin sanyaya su ne sababbin wata na ƙwararraka, har da yaushe a kan wasu abincin kamar tsini ko ruwa na ƙasa. Masana suka yi takaice cewa amfani da ƙwayoyin amfani da kwararraka da kuma gyara tsarin aiki zai iya ƙara ƙarfi a cikin tsorata ga masu aiki.
