Binlerce y\u0131l \u00f6nce, Kaliforniya Kanal Adalar\u0131’ndaki yerli gruplar, do\u011fal bir petrol maddesi olan bit\u00fcmle kaplanm\u0131\u015f saz bitkilerinden, son derece yarat\u0131c\u0131 su kaplar\u0131 yapt\u0131lar. Bu kadim kaplar ama\u00e7lar\u0131na iyi hizmet etse de, son ara\u015ft\u0131rmalar, \u00fcretimleriyle ili\u015fkili olas\u0131 bir sa\u011fl\u0131k tehlikesine \u0131\u015f\u0131k tuttu.<\/p>\n\n
Sualt\u0131 kaynaklar\u0131ndan Kanal Adalar\u0131’na s\u0131zan bit\u00fcm, polisiklik aromatik hidrokarbonlar (PAH’lar) olarak bilinen toksik kimyasallar i\u00e7erir. Bu kimyasallar, solundu\u011funda veya yutuldu\u011funda kanser de dahil olmak \u00fczere \u00e7e\u015fitli sa\u011fl\u0131k sorunlar\u0131na yol a\u00e7abilirler.<\/p>\n\n
Kaliforniya \u00dcniversitesi’ndeki ara\u015ft\u0131rmac\u0131lar, arkeolojik kan\u0131tlar ve etnografik kay\u0131tlar kullanarak antik \u015fi\u015fe yap\u0131m s\u00fcrecini yeniden yaratma projesine giri\u015ftiler. Adalarda ya\u015fayan yerli bir grup olan Chumash’lar\u0131n kulland\u0131\u011f\u0131 teknikleri titizlikle takip ettiler.<\/p>\n\n
Ara\u015ft\u0131rmac\u0131lar, k\u00fctle spektrometrisi kullanarak, bit\u00fcm eritme i\u015flemi s\u0131ras\u0131nda havaya sal\u0131nan kirleticileri \u00f6l\u00e7t\u00fcler. Ayr\u0131ca, bitmi\u015f \u015fi\u015feleri su ve zeytinya\u011f\u0131 ile doldurarak zaman i\u00e7inde ger\u00e7ekle\u015fen kimyasal s\u0131z\u0131nt\u0131y\u0131 de\u011ferlendirdiler.<\/p>\n\n
Sudaki ve ya\u011fdaki PAH konsantrasyonlar\u0131, acil sa\u011fl\u0131k riskleri olu\u015fturacak kadar y\u00fcksek olmasa da, havadaki seviyeler \u00c7evre Koruma Ajans\u0131 (EPA) taraf\u0131ndan belirlenen g\u00fcvenlik s\u0131n\u0131rlar\u0131n\u0131 a\u015ft\u0131. Eriyen bit\u00fcm\u00fcn \u00fczerinde duran ki\u015filer, sigara duman\u0131ndakine benzer PAH konsantrasyonlar\u0131n\u0131 soluyacaklard\u0131.<\/p>\n\n
\u00c7al\u0131\u015fma, bit\u00fcm eritme i\u015flemindeki PAH’lara maruz kalman\u0131n, Chumash’lar\u0131n sa\u011fl\u0131\u011f\u0131ndaki d\u00fc\u015f\u00fc\u015fe katk\u0131da bulunmu\u015f olabilece\u011fini \u00f6ne s\u00fcr\u00fcyor. Chumash halk\u0131n\u0131n, yakla\u015f\u0131k 5.000 y\u0131l \u00f6nce ba\u015flayan iskelet lezyonlar\u0131na, k\u00f6t\u00fc di\u015f sa\u011fl\u0131\u011f\u0131na ve k\u00fc\u00e7\u00fclen kafa boyutlar\u0131na sahip oldu\u011fu bulundu.<\/p>\n\n
\u00c7al\u0131\u015fma, yeti\u015fkinlerin PAH’lara maruz kalmas\u0131na odakland\u0131, ancak k\u00fc\u00e7\u00fck \u00e7ocuklar zararl\u0131 etkilerine daha yatk\u0131nd\u0131r. Gelecekteki ara\u015ft\u0131rmalar, erken d\u00f6nem maruziyet seviyelerini inceleyebilir. Ayr\u0131ca ara\u015ft\u0131rmac\u0131lar, PAH’lara maruz kalman\u0131n, Chumash’lar\u0131n sa\u011fl\u0131k sorunlar\u0131ndaki d\u00fc\u015f\u00fc\u015f\u00fcne katk\u0131da bulunan tek potansiyel fakt\u00f6r oldu\u011funun fark\u0131ndalar.<\/p>\n\n
