Sulfur dioxide(二氧化硫)is an important compound in its own right。It is used in the manufacture of paper。When made from wood pulp or from other materials,paper is usually pale yellow in colour。 Sulfur dioxide is used to bleach(漂白)it to the white colour which is needed。Sulfur dioxide ...
The actual concentration need not be large for a substance to be a pollutant; in fact the numerical value tells us little until we know how much of an increase this represents over the concentration that would occur naturally in the area. For example, sulfur dioxide has detectable health ...

However, DIC microscopy analysis of a subset of the un-hatched eggs showed that they harboured worm embryos (Fig. 2D) indicating that the effect of fluensulfone is not on the self-fertilization that occurs within the adult hermaphrodite, but rather after this process: Most likely the compound ...
Thiosulfate oxidation by microbes has a major impact on global sulfur cycling. Here, we provide evidence that bacteria within various Roseobacter lineages are important for thiosulfate oxidation in marine biofilms. We isolate and sequence the genomes of
The sulfur cycle across the lithosphere and the role of this volatile element in the metasomatism of the mantle at ancient cratonic boundaries are poorly constrained. We address these knowledge gaps by tracking the journey of sulfur in the assembly of a Proterozoic supercontinent using mass independe...
