I hope all the precautions against air pollution, as suggested by the local government, will be seriously considered here.
请问 as suggested by the local government, will be seriously considered here.是此句
的什么成分，还有为什么用as不用while

as 表示“作为。。。"之意，as suggested by the local government作为句子的插入语，做解释说明用。主句为I hope all the precautions against air pollution will be seriously considered here.
一般，两个逗号之间的句子都是插入语，句子的结构可能是不完整的，做前一句或者整句话某一成分的补充说明
整句话的意思是，我希望所有针对大气污染的预 防措 施，作为当地政 府的提议【这里指的就是预 防措 施】，都能够在此被严肃考虑。
希望对您有所帮助，有不明白的地方欢迎追问~

as suggested by the local government是定于修饰the precautions。这句话可以这样写I hope all the precautionsas suggested by the local government against air pollution will be seriously considered here.
