To monitor Hydrogen Sulfide
Hydrogen sulfide, H2S, is a very poisonous, corrosive, and flammable gas. As such, it needs to be carefully monitored and controlled in industrial processes where it is generated or used. At relatively low concentrations, it has an odour of rotten eggs which effectively works as a warning, but at higher concentrations where it becomes acutely toxic and even lethal, it can no longer be smelled and ...

Collecting data to explore the ecological threat of nanomaterials
The overall ecological impact of 10 engineered nanomaterials has been modelled for the first time using toxicity data from multiple living species. These models will allow researchers to assess the effect nanomaterials may have on both ecosystems and people. Engineered nanomaterials (ENMs) are small-scale substances measuring less than 100 nm in at least one dimension. They are increasingly used ...
