ملخص المقالة :
بررسی نتایج آنالیز عناصر سنگین در نمونه های خاک منطقه مورد مطالعه نشان از غلظت بالای برخی عناصر از قبیل کروم، نیکل و کبالت در بخش های جنوبی منطقه دارد. ارزیابی فلزات سنگین در خاک های منطقه جغتای توسط روش های آماری چند متغیره( ضریب همبستگی پیرسون، آنالیز خوشه ای و تحلیل مولفه اصلی) نشان دهنده همبستگی مثبت و قوی عناصر کبالت، نیکل، کروم، آهن، منگنز و منیزیم می باشد که ناشی از منشا یکسان آنها ( واحدهای افیولیتی و الترامافیکی منطقه ) می باشد. محاسبه شاخص های آلودگی ( فاکتور زمین انباشتگی، فاکتور غنی شدگی، فاکتور آلودگی و درجه آلودگی اصلاح شده) نشان می دهد که خاک های منطقه نسبت به عناصر کروم و نیکل آلودگی شدید و نسبت به عنصر کبالت آلودگی متوسط دارند. آزمایش استخراج ترتیبی بر روی نمونه های آلوده نشان داد که عناصر نیکل و کروم با غلظت بیش از 50 درصد در فاز تبادل پذیرتمرکز یافته اند. به عبارت دیگر وجود واحد های افیولیتی و معدنکاری بر روی واحدهای کرومیتی در منطقه سبب آزاد شدن این عناصر گردیده است ، به طوری که با دور شدن از واحدهای افیولیتی، غلظت این عناصر کاهش می یابد. همچنین گونه سازی عناصر در فاز های مختلف نشان داد که سایر عناصر اغلب در فازهای باقی مانده تمرکز یافته و منشا لیتوژنیک دارند.
