Measuring excreted drug residues in wastewater is a non-invasive approach to monitor drug consumption trends across a specific community or location. Here a combination of simplified sample preparation and high sensitivity mass spectrometry was applied to the study of drugs of abuse in wastewater surveillance. Quantification of 12 common drugs of abuse from wastewater was demonstrated, with

Get PriceSulfur hexafluoride SF6 gas hazards. Sulfur hexafluoride (SF6) is colorless, odorless, heavier than air and is not considered as toxic.However it is suffocating at high concentrations (it replaces oxygen) just like inert gases (also called noble gases). Sulfur hexafluoride has no lower and upper explosive limits but can severely react with disilane and form a dangerous explosive gas mixture.
