The monitoring of toxic organic compounds in environmental matrices has seen significant advancements, particularly with the development of sensitive and selective analytical methods, including chromatography-mass spectrometry techniques, for detecting emerging contaminants. The importance of standardized sampling and sample preparation protocols is also discussed to ensure data reliability and comparability across different studies and regions, which is crucial for effective environmental health risk assessment [1].
Polycyclic aromatic hydrocarbons (PAHs) are a class of organic pollutants frequently found in urban air, especially in proximity to industrial zones. Studies utilizing gas chromatography-mass spectrometry (GC-MS) have identified specific PAH congeners and their concentrations, linking elevated levels to traffic emissions and industrial activities, underscoring the need for targeted emission control strategies to mitigate exposure risks [2].
The solid-phase extraction (SPE) of persistent organic pollutants (POPs) from water samples is a critical step for their accurate trace-level quantification in complex environmental matrices. Research into novel sorbent materials for SPE has focused on improving extraction efficiency and selectivity for a range of POPs, including pesticides and dioxins [3].
Phthalates are a group of chemicals commonly used in plastic products, and their bioaccumulation in freshwater fish from industrialized rivers is a growing concern. Studies employing liquid chromatography-tandem mass spectrometry (LC-MS/MS) have quantified phthalate levels in fish tissues, revealing significant contamination and calculating bioaccumulation factors that indicate potential risks to both aquatic ecosystems and human consumers of fish, highlighting the need for effective wastewater treatment [4].
Volatile organic compounds (VOCs) are prevalent in indoor air and can contribute to indoor air pollution. Novel methods, such as headspace solid-phase microextraction coupled with GC-MS, have been developed for the simultaneous determination of VOCs in indoor air, demonstrating high sensitivity and rapid analysis, enabling the identification of key VOC sources essential for improving indoor environmental quality and public health [5].
Bisphenols and their analogs are endocrine-disrupting compounds that have been detected in tap water samples from various locations. Studies using LC-MS/MS have found widespread contamination, with some analogs detected at higher concentrations than bisphenol A, highlighting the challenges of removing these compounds from drinking water sources [6].
Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that are highly persistent in the environment. Their presence in soil samples collected near industrial manufacturing sites has been investigated using liquid chromatography coupled with high-resolution mass spectrometry (LC-HRMS), revealing significant contamination and potential risks of PFAS migration into groundwater [7].
Pharmaceutical residues in wastewater pose a threat to aquatic ecosystems and potentially human health. Advanced oxidation processes (AOPs), such as the combination of ozonation and UV irradiation, have shown significant degradation of common drug contaminants, demonstrating their potential in improving the quality of treated wastewater and reducing the environmental burden of pharmaceuticals [8].
Organophosphate flame retardants (OPFRs) are commonly found in indoor dust samples from residential buildings, posing potential human exposure pathways through inhalation and dermal contact. Studies using gas chromatography with an electron capture detector (GC-ECD) have quantified OPFRs, revealing widespread contamination and emphasizing the need for safer alternatives [9].
Biosensors offer a promising approach for the rapid detection of environmental toxins. Recent developments in biosensing platforms, including electrochemical, optical, and piezoelectric sensors, are being explored for monitoring toxic organic compounds in water and air, emphasizing the advantages of biosensors for on-site, real-time analysis [10].
The analysis of toxic organic compounds in environmental samples is a critical area of environmental science, with recent reviews highlighting advancements in sensitive and selective analytical methods, such as chromatography-mass spectrometry.
