Researchers then took saliva and tongue coating samples to measure bacteria levels and odour-causing compounds , including hydrogen sulphide .
然后研究人员对他们的唾液和舌表覆盖物中的细菌含量和口腔气体混合物进行了检测,包括硫氢化物。
Microscopic marine creatures absorb carbon dioxide from the atmosphere and release oxygen for the rest of creation to breathe ; they also release dimethyl sulphide in quantities sufficient to affect the physics of clouds far above the ocean ; and they provide the primary food for all the fish that humans hunt .
