For over 48 hours the white smoke from sulfur dioxide could be seen in the air.

It tends to turn back into sulfur dioxide and water again.

There are several ways of measuring sulfur dioxide in the air.

Released sulfur dioxide however makes the water a strong reducing agent.

Therefore, it is not a conclusive test for sulfur dioxide.

He said the restrictions on sulfur dioxide will be the most stringent in the nation.

In addition, sulfur dioxide cannot be added to organic wines.

Sulfur dioxide is a by-product of other processes in industry.

Such paper has maintained its strength for 300 to 800 years, despite sulfur dioxide and other air pollutants.

At that time, up to 48,000 pounds per hour of sulfur dioxide were released from this one stack.

The process uses a natural gas flame to break down the effluent into sulphur dioxide.

Also, there was a good trace of sulphur dioxide in its atmosphere.

Experts have described the coal as similar to natural gas in terms of its sulphur dioxide content.

They also give off sulphur dioxide, one of the major causes of acid rain.

The Finnish oil industry has reduced emissions of sulphur dioxide by 80 per cent in the past 12 years.

On the other hand, there is not expected to be any difference in emissions of sulphur dioxide and other particles.

The second major issue was the maximum level of sulphur dioxide and sulphites permitted in food.

Where we have greater problems are, firstly, on sulphur dioxide.

Measures have been taken in Europe to control sulphur dioxide and nitrogen oxide emissions since the 1970s, with some success.

This is well known for metabisulphites and sulphur dioxide (see p 291).
