Amines in the Environment

Reactivity of a luminescent “off–on” pyrylium dye toward various classes of amines and its use in a fluorescence sensor microtiter plate for environmental samples

“…The need to determine amines has increased over the last few years because of growing concentrations found in soil or in waste water [1]. Primary aliphatic amines are widely distributed in manufacturing industries and in biological bodies or food (as biogenic amines).…”

Thin‐Layer and Wall‐Jet Arrangement of Amperometric Detector with Boron‐Doped Diamond Electrode: Comparison of Amperometric Determination of Aminobiphenyls in HPLC‐ED

“…In our laboratory, a pen-type BDD disk electrode was designed [2] and successfully used for voltammetric determination of 2-aminobiphenyl (2-AB), 3-aminobiphenyl (3-AB), and 4-aminobiphenyl (4-AB) [18], 3-nitrofluoranthene and 3-aminofluoranthene [19], and phenolic compounds in foods [13]; in the latter study this electrode was also employed in laboratory-made wall-jet amperometric detection cell. The thin-layer arrangement was tested for HPLC-ED determination of aminobiphenyls (ABs) [20,21], widespread environmental pollutants [22] with potential (2-AB and 3-AB) or proven (4-AB) carcinogenic effect to humans [23]. These compounds are used as raw material or intermediates in manufacturing of pesticides, dyestuffs, polymers and other industrial chemicals [24] and enter the environment due to their relatively high polarity and water solubility.…”

Aromatic Amines Sources, Environmental Impact and Remediation

“…They are the second most abundant family of organic constituents present in the biosphere after carbohydrates. Since the start of the industrial revolution, a wide variety of aromatic pollutants have also been introduced into the environment through anthropogenic activity (Fekete et al 2010). Some examples or aromatic amines, their origin and impact are listed in Table 7.1. Aniline, which is essentially phenylamine, is the simplest aromatic amine.…”
