“…Table 1 shows a comparative evaluation of their performance. For conventional chromatography (including GC/FID, GC/MS and HPLC )28293031, off-line sample pretreatment and preconcentration steps are required. Although latest attempts circumventing this step via e.g., membrane inlet proton transfer reaction mass spectrometry (MI-PTRMS) techniques32 and coupling of membrane inlets GC/MS33, the rather complex operating procedures and high instrumental costs still limit their widespread application.…”

Chlorinated aliphatic hydrocarbons and chlorinated aromatic hydrocarbons (CHCs) are toxic and carcinogenic contaminants commonly found in environmental samples, and efficient online detection of these contaminants is still challenging at the present stage. Here, we report an advanced Fourier transform infrared spectroscopy-attenuated total reflectance (FTIR-ATR) sensor for in-situ and simultaneous detection of multiple CHCs, including monochlorobenzene, 1,2-dichlorobenzene, 1,3-dichlorobenzene, trichloroethylene, perchloroethylene, and chloroform. The polycrystalline silver halide sensor fiber had a unique integrated planar-cylindric geometry, and was coated with an ethylene/propylene copolymer membrane to act as a solid phase extractor, which greatly amplified the analytical signal and contributed to a higher detection sensitivity compared to the previously reported sensors. This system exhibited a high detection sensitivity towards the CHCs mixture at a wide concentration range of 5~700 ppb. The FTIR-ATR sensor described in this study has a high potential to be utilized as a trace-sensitive on-line device for water contamination monitoring.

“…For example, one study used a HP‐FFAP column for styrene (Paraskevopoulou and others ) and Rtx‐5 column for oligomers. In another study with GC‐FID, Gramshaw and Vandenburg () used a BP‐1 column (oven temperature 200 °C) and injecting in a cold on‐column mode, while a HP‐5 column was used with a lower oven temperature program (from 50 to 150 °C), followed by SPME extraction (Silva and others ). Dynamic headspace chromatography equipped with purge‐and‐trap injector, and a FID detector was used to determine styrene in yogurt (Ehret‐Henry and others ), employing separation on a DB‐5 column (30 m × 0.32 mm).…”

Polymeric packaging protects food during storage and transportation, and withstands mechanical and thermal stresses from high-temperature conventional retort or microwave-assisted food processing treatments. Chemical compounds that are incorporated within polymeric packaging materials to improve functionality, may interact with food components during processing or storage and migrate into the food. Once these compounds reach a specified limit, food quality and safety may be jeopardized. Possible chemical migrants include plasticizers, antioxidants, thermal stabilizers, slip compounds, and monomers. Chemical migration from food packaging is affected by a number of parameters including the nature and complexity of food, the contact time and temperature of the system, the type of packaging contact layer, and the properties of the migrants. Researchers study the migration of food-packaging compounds by exposing food or foodsimulating liquids to conventional and microwave heating and storage conditions, primarily through chromatographic or spectroscopic methods; from these data, they develop kinetic and risk assessment models. This review provides a comprehensive overview of the migration of chemical compounds into food or food simulants exposed to various heat treatments and storage conditions, as well as a discussion of regulatory issues.

Sanitary sewer collection and stormwater conveyance infrastructure is increasingly being repaired by trenchless pipeline rehabilitation methods such as cured-in-place-pipe (CIPP). This project was conducted to determine the degree the CIPP installation process and cured material impacted stormwater quality. Condensate generated during the installation was characterized. Stormwater was monitored for five weeks. Cured CIPP was also extracted in a laboratory. Waters were analyzed for chemical oxygen demand (COD), UV absorbance, presence of volatile and nonvolatile contaminants, as well as their toxicity to Daphnia magna. Results demonstrated that CIPP installation activities contaminated stormwater at and downstream of the installation sites. For five weeks following CIPP installations stormwater was found to be contaminated as demonstrated by elevated COD levels and the presence of styrene. Styrene is one of many compounds that were released into the stormwater by the CIPP process. The CIPP process liquid contained a pH of 6.2, 36,000 mg/L COD, and elevated styrene level. This liquid totally dissolved D. magna organisms during the toxicity test within 24 hr; no organisms remained for mortality counting. When process liquid was diluted 10,000 times, 100% mortality of the D. magna occurred.
