We limit the contribution of the hot intracluster gas, by means of theSunyaev-Zel'dovich effect, to the temperature anisotropies measured by theTenerife experiment. The data is cross-correlated with maps generated from theACO cluster catalogue, the ROSAT PSPC catalogue of clusters of galaxies, acatalogue of superclusters and the HEAO 1 A-1 map of X-ray sources. There is noevidence of contamination by such sources at an rms level of $\sim 8\mu$K at99onfidence level at $5^o$ angular resolution. We place an upper limit onthe mean Comptonization parameter of $ y \le 1.5\times 10^{-6}$ at the samelevel of confidence. These limits are slightly more restrictive than thosepreviously found by a similar analysis on the COBE/DMR data and indicate thatmost of the signal measured by Tenerife is cosmological.
