Water and air (and probably soil) are severely polluted over large parts of China. The Chinese have been so fortunate to have a government that did not interfere and impose restrictions on pollutant emissions. Yeah, right.

Acid rain was a sulphur dioxide problem. Certain heavy oils have as much as 4% sulphur [I forget how many have how much]. When the residues are burned as fuel oil, the SO2 dissolves in water droplets and forms acidic rain. Flue gas desulphurisation was introduced to stop acid rain. en.wikipedia.org Sulphur in general has been increasingly stripped from crude oil and distillates as it's tough on everything. Diesel engines used to have to cope with 0.5% sulphur. Where sulphur is good as a fuel for heat and electricity generation is in fertilizer plants which burn pure sulphur as fuel to produce sulphuric acid. Coal is pretty grubby too with plenty of sulphur dioxide coming out the stack, along with other nasties. Around the world, chimneys have been cleaned up a LOT. Fortunately, most of the sulphur, lead, vanadium, particulate, etc problem is for the locals who have the chimneys, so they have incentive to clean up their own backyard. CO2 is exported and if it's a problem, it's a problem for foreigners more than locals [locals being small in number, foreigners being large]. So if it's a problem, it's the old tragedy of the commons problem. Mqurice
