اكتشاف عامل مساهم في انهيار حضارة المايا

ما يعرفه ريفو عن الخبر

قد يكون تلوث الزئبق في الخزانات المائية أحد الأسباب الرئيسية لزوال حضارة المايا خلال العصر الكلاسيكي.
أظهرت التحاليل أن مستويات الزئبق في بحيرتي كوبا وإكسكانشي تجاوزت الحدود المسموح بها بعدة مراتب.
ترافق ارتفاع تركيز الزئبق مع انهيار النظم البيئية المائية واختفاء أنواع من القشريات والرخويات.
وجد العلماء كميات كبيرة من أصباغ الزئبق في المدافن وتربة المدن مما أثر سلبا على صحة السكان.

اكتشف علماء الكيمياء القديمة أن استخدام المايا المكثف للأصباغ الحمراء المحتوية على مركبات الزئبق أدى إلى تراكمها السريع في المياه والبيئة والمياه، ما فاقم الوضع البيئي في المنطقة.
