The Hill gazetesinin haberine g\u00f6re, Columbia \u00dcniversitesinden ara\u015ft\u0131rmac\u0131lar, yeni bir lazer g\u00f6r\u00fcnt\u00fcleme y\u00f6ntemi kullanarak pet \u015fi\u015felerdeki nanoplastikleri inceledi.<\/p>\n
Yeni y\u00f6ntemle metrenin milyarda biri \u00f6l\u00e7e\u011finde \u00f6l\u00e7\u00fclebilen partik\u00fclleri tan\u0131mlamay\u0131 ba\u015faran ara\u015ft\u0131rmac\u0131lar, bir litrelik pet \u015fi\u015fedeki suda yakla\u015f\u0131k 240 bin nanoplastik bulundu\u011funu belirledi.<\/p>\n
Ara\u015ft\u0131rmac\u0131lardan Beizhan Yan, plasti\u011fin boyutu k\u00fc\u00e7\u00fcld\u00fck\u00e7e tehlikenin artt\u0131\u011f\u0131n\u0131, \u00e7\u00fcnk\u00fc par\u00e7ac\u0131k boyutu k\u00fc\u00e7\u00fcld\u00fck\u00e7e insan v\u00fccuduna girme ihtimalinin fazlala\u015ft\u0131\u011f\u0131n\u0131 belirtti.<\/p>\n
Pet \u015fi\u015felerdeki suda bulunan plastik partik\u00fcllerinin kan-beyin bariyerini ge\u00e7ebilecek kadar k\u00fc\u00e7\u00fck oldu\u011funu ifade eden Yan, bu nedenle ilerleyen ya\u015flarda beynin belirli b\u00f6lgelerindeki h\u00fccrelerin kayb\u0131na yol a\u00e7abilece\u011fini s\u00f6yledi.<\/p>\n
Yan, ayr\u0131ca bu k\u00fc\u00e7\u00fck plastiklerin “kana ge\u00e7ebilece\u011fi, h\u00fccrelere ula\u015fabilece\u011fi ve ard\u0131ndan organlar\u0131n i\u015flevlerini yitirebilece\u011fi” de\u011ferlendirmesinde bulundu.<\/p>\n
Bu plastiklerin v\u00fccuda i\u00e7me suyu yoluyla girdi\u011fi i\u00e7in h\u0131zl\u0131 etkiler g\u00f6sterdi\u011fini d\u00fc\u015f\u00fcnen ara\u015ft\u0131rmac\u0131lar, k\u00fc\u00e7\u00fck plastiklerin, ba\u011f\u0131rsaklarda yiyeceklerin sindirilmesine yard\u0131mc\u0131 olan mikroplar\u0131n etkilenmesine yol a\u00e7abilece\u011fini belirtti.<\/p>\n
Ayr\u0131ca plastiklerin, artan \u00f6l\u00fcm oran\u0131 ve do\u011fum kusurlar\u0131 gibi sa\u011fl\u0131k risklerine neden olabilece\u011fi de\u011ferlendiriliyor.<\/p>\n
Ara\u015ft\u0131rmac\u0131lar, bu plastiklerin ambalajdaki malzemelerden sal\u0131nd\u0131\u011f\u0131 veya suyun \u00fcretimi s\u0131ras\u0131nda ortaya \u00e7\u0131kt\u0131\u011f\u0131n\u0131 d\u00fc\u015f\u00fcn\u00fcyor.<\/p>\n
\u00d6te yandan, insanlar\u0131n hangi plastikleri hangi miktarlarda yuttu\u011fu ve v\u00fccuda ne kadar plastik girdi\u011fi hen\u00fcz bilinmiyor.<\/p>\n
