Brain at risk from the environment

（環境污染嚴重損害大腦）

Pollution and other environmental threats are harming the intelligence of millions of people across the world, says a United Kingdom review of the available evidence.

The causes are poisons such as lead, PCBs, and radiation.

據英國雜志報道，污染與其它環境問題正在威脅著全世界成千上百萬人們的智力發育。

其主要原因在于人們使用的導線、電路板與輻射的毒害作用。

另一個大問題是由于土壤腐蝕而導致的農作物中的鐵和碘等微量元素的流失，科學家說很難完全了解問題已經有多嚴重，因為數據實在太難統計了。
