The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, s...
Structure of Amines If we look at the amine molecule, it will display a shape that of a flattened triangular pyramid wherein the nitrogen atom is at the apex. There is an unshared electron pair that is localised above the nitrogen atom. In the case of quaternary ammonium ions, a substitue...
Common pollutants include unburned hydrocarbons (HC), carbon monoxide (CO), nitrogen oxides (NOx) or particulate matter (PM). The total concentration of pollutants in diesel exhaust gases typically amounts to some tenths of one percent—this is schematically illustrated in Figure 1. Much lower, ...
As for personal care products, only Disodium EDTA is detected in wastewater, while in groundwater the concentrations of all the analyzed substances are lower than the instrumental detection limit. Keywords: sewer; leakage; urban semi-confined groundwater; personal care products; microbiological ...

To the uninformed eye, one may look very much like the other, but their chemical composition is very different. In fact, a relatively small amount of bioplastic can contaminate conventional plastic recycling, preventing the salvaged plastic from being reused and stopping recycling companies from ...

There is a growing concern in Sweden and elsewhere that continued emissions of per- and polyfluoroalkyl substances (PFASs) may cause environmental as well as human health effects. PFASs are a broad class of man-made substances that have been produced and
PFASs are a broad class of man-made substances that have been produced and used in both commercial products and industrial processes for more than 60 years. Although the production and use of some PFASs has been phased-out in some parts of the world, it is not known what effect these ...
