1967 New Scientist 9 Nov. 333/1 The continuation and evolution of life depends upon a stable eco-system. A characteristic of such a system is that cyclical transformations of the major biological elements take place within it—the carbon cycle, the nitrogen cycle, the *sulphur cycle and so on.

1973 R. G. Krueger et al. Introd. Microbiol. xxx. 745/2 Bacteria can carry out each of the processes in the sulfur cycle; bacteria and certain colorless blue-green algae are the only known living agents of the steps involving interconversions of inorganic forms of sulfur.

1977 I. M. Campbell Energy & Atmosphere viii. 289 More efficient dispersal of sulphur dioxide at source cannot be regarded as an acceptable long term solution, since that merely transfers the problem to another region or country, the problem intensified by the fact that the anthropogenic term in the sulphur cycle is of the same order of magnitude as the natural terms.
