1.   Investigators suspect that many of the cargoes of coal had a high sulphur content.

2.   Particular concern was caused by the fact that Kuwaiti crude included a high sulphur content, which would turn into sulphur dioxide on burning and fall as acid rain.

3.   This will enable it to continue using British coal, which has a relatively high sulphur content, while meeting EC standards on sulphur emissions.

4.   An Indonesian mining company, PT Adaro, has started mining coal with a very low sulphur content from a huge deposit in southern Kalimantan.

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

6.   Orimulsion, a new bitumen-based fuel from Venezuela, has been widely criticized as a dirty fuel because of its high sulphur content.

7.   Both metal samples prove, without doubt, that cheap steel with a high sulphur content had been used.

8.   But steel with high sulphur content becomes brittle, and if deformed, cracks or snaps at low temperatures.

9.   He said it was high time automotive diesel with lower sulphur content was introduced as the level of acidity had, on occasion, exceeded the tolerable level.
