As the amount of oxygen in the air has gone down, the concentration of carbon oxide and other dangerous gases has shot up.

由于空气中氧气的含量降低，二氧化碳和其他危险气体的浓度上升。

The high concentration of carbon oxide and hydrogen chloride produced by LPG is 80 per cent less than that produced by a petrol engine.

液化石油气所产生的高关注的碳氧化物和氢氧化物，比汽油引擎产生的还少百分之80。
