我要说的是，我们不分青红皂白地将这些有毒的、具有强大生物功能的化学制品，交给了那些对这些制品的潜在危害基本上或者完全无知的人去使用。

I do contend that we have put poisonous and biologically potent chemicals indiscriminately into the hands of persons largely or wholly ignorant of their potentials for harm.

水体中有毒重金属离子和有机物对生物体造成极大的危害，其痕量分析颇具研究价值。

Toxic heavy metal ions and some toxic organic compounds in water are great threats for human beings and living organisms, so their trace analyses are very important.
