Hakemli mecmua JAMA Pediatrics’te yay\u0131mlanan ara\u015ft\u0131rmaya nazaran, su ve ba\u015fka kaynaklardan y\u00fcksek \u00f6l\u00e7\u00fcde flor\u00fcre maruz kalan \u00e7ocuklar\u0131n IQ d\u00fczeyleri \u00f6nemli formda d\u00fc\u015f\u00fcyor.<\/p>\n
Ara\u015ft\u0131rmac\u0131lar, idrar \u00f6rneklerindeki her bir ppm (milyonda bir par\u00e7a) flor\u00fcr art\u0131\u015f\u0131 i\u00e7in \u00e7ocuklar\u0131n IQ’sunda ortalama 1,63 puanl\u0131k bir d\u00fc\u015f\u00fc\u015f oldu\u011funu tespit etti. Bu bulgu, y\u00fcksek flor\u00fcrl\u00fc b\u00f6lgelerde ya\u015fayan \u00e7ocuklar\u0131n zek\u00e2 geli\u015fiminin olumsuz etkilenebilece\u011fi tasas\u0131n\u0131 art\u0131rd\u0131.<\/p>\n

Ba\u015fka bir tenkit ise, incelenen \u00fclkelerdeki suyun flor\u00fcr d\u00fczeyinin ABD’deki seviyeyi yans\u0131tmamas\u0131yd\u0131.<\/p>\n
ABD’de i\u00e7me suyundaki flor\u00fcr d\u00fczeyi i\u00e7in belirlenen \u00fcst hudut 0,7 ppm olmas\u0131na kar\u015f\u0131n, milyonlarca Amerikal\u0131 farkl\u0131 kaynaklardan daha y\u00fcksek d\u00fczeylerde flor\u00fcr i\u00e7eren sular t\u00fcketiyor. T\u00fcrkiye’de ise bu hudut 1,5 ppm olarak belirlenmi\u015f durumda.<\/p>\n

\u0130lgin\u00e7 bir bi\u00e7imde, yeni ara\u015ft\u0131rmada 1,5 ppm’in alt\u0131ndaki flor\u00fcr d\u00fczeyleri ile \u00e7ocuklar\u0131n IQ’su ortas\u0131nda manal\u0131 bir ili\u015fki bulunamad\u0131.
