In high school and college I worked at Kingston steel drum, a factory in my New Hampshire hometown that scoured some of the 55-gallon steel drums it cleaned with acid and scalding water.
Acid rain and polluted air also damage the bricks and stonework of buildings, and corrode the metalwork of steel Bridges and railings.
酸雨和被污染的大气还会侵蚀建筑物的砖块和石造的部分，腐蚀钢制桥梁和铁轨的金属部分。

We might look upon the glory of our Rust Belt states, where there are hundreds of vast steel mills that are at least 40 years out of date and also spew smoke that causes acid rain.
