The first big choice involves tackling sulfur dioxide.

最大的选择是如何处理二氧化硫。

Instead of lava, ash, and sulfur dioxide, these volcanoes spew mud and methane.

这里的火山喷涌出的不是岩浆、火山灰和二氧化硫，而是泥浆和甲烷。

Sulfur dioxide can stop by the oxygen in air make wine caused by the oxidation.

二氧化硫可以阻止由空气中的氧使葡萄酒所引起的氧化作用。

Large eruptions can release huge clouds of sulfur dioxide into the stratosphere.

火山爆发可以向大气中的平流层释放大量二氧化硫。

They are mostly sulfur dioxide and nitrogen dioxide from power plants, auto exhausts and industry.

这些颗粒物大多为发电厂、汽车工业和汽车尾气排出的二氧化硫和二氧化氮。
