严重的污染英文

environmental pollution is serious

The environment has been polluted seriously.

heavily-polluted

the air pollution is very heavy

the air is polluted seriously

你好，英语里关于“污染较重的”表达很多，如 heavily polluted、seriously polluted 以及 severely polluted。从使用频率上来讲，seriously polluted 要比 heavily polluted 频率高一些，severely polluted 多用于正式场合或者文献。希望我的回答能有所帮助！

light pollutionmedium level pollutionserious pollution

对，是light,medium and heavy pollutionserious和severe也可以，但是是严重的污染之意，不成套。
