[More] The photocatalytic degradation of a series of six acid dyes (Direct Red 80, Direct Red 81, Direct Red 23, Direct Violet 51, Direct Yellow 27, and Direct Yellow 50) has been tested compared in terms of color removal, mineralization, and toxicity (Lactuca sativa L. test) after photocatalysis on immobilized titanium dioxide. The dyes were examined at their natural pH and after hydrolysis at pH 12. Results show that hydrolysis decreases strongly the efficiency of color removal, that full mineralization takes much longer reaction time than color removal, and that toxicity is only very partially reduced. Some structural parameters, related to the structure and the topology of the dye molecules, could be correlated with the apparent color removal rates at natural pH.

Simultaneous determination of volatile organic compounds (VOCs) with a wide range of polarities in urine by headspace solid-phase microextraction (HS-SPME) coupled to gas chromatography-mass spectrometry

Authors: Song, HN; Kim, CH; Lee, WY; Cho, SH (2017) Rapid Communications in Mass Spectrometry 31:613-622. HERO ID: 3491053

[Less] RATIONALE: Volatile organic compounds (VOCs) are ubiquitous environmental pollutants . . . [More] RATIONALE: Volatile organic compounds (VOCs) are ubiquitous environmental pollutants that have a high vapor pressure at room temperature. Some VOCs have been classified as carcinogenic to humans by the International Agency for Research on Cancer (IARC), because they can bind to DNA and cause cell mutations. Therefore, monitoring of VOCs in human urine is very important to evaluate the correlation between exposure to VOCs and human disease.

METHODS: We have developed an improved analytical method for the simultaneous determination of VOCs with a wide range of polarities in human urine samples by headspace solid-phase microextraction (HS SPME) coupled to gas chromatography-mass spectrometry (GC/MS). In the improved method, a bi-polar carboxen-polydimethylsiloxane (CAR/PDMS) fiber was used for the optimized extraction of 15 VOCs with a wide range of polarities, including benzene, toluene, ethylbenzene, xylenes (BTEX), alkylbenzenes, cresols, and naphthalene, in human urine samples.. Extracted VOCs from the human urine were effectively separated by GC using a mid-polarity column (DB-35, 35% phenylmethylpolysiloxane) and monitored by mass spectrometry using extracted ion monitoring (EIM) mode.

RESULTS: Under the optimized method, the linearity of the calibration curves was greater than 0.993. The limits of detection (LODs) at a signal to noise (S/N) ratio of 3 were 0.3-0.6 ng/mL. The coefficients of variation were in the range of 0.1 - 9.7 % for within-day variation and 0.2 - 14.2 % for day-to-day variation.

CONCLUSIONS: The method was shown to be rapid and simple for the simultaneous determination of VOCs with a wide range of polarities in human urine and it could be applied to monitoring and to biomedical investigations to check exposure of VOCs.

Evaluation of dioxins and dioxin-like compounds from a cement plant using carbide slag from chlor-alkali industry as the major raw material

[More] Carbide slag produced from chlor-alkali industry contains high amounts of calcium compounds and can potentially be used as raw material for cement production; however, it contains large amounts of chlorine so it is essential to evaluate the emissions of chlorinated organic pollutants, including polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), polychlorinated biphenyls (PCBs), and polychlorinated naphthalenes (PCNs). A field study of the emission profiles of these pollutants in a cement plant using such slag was performed. The average concentrations of PCDD/Fs, PCBs, and PCNs in stack gases collected at the kiln back end were 6.31, 1.07, and 31.89pg TEQ m(-3), respectively. PCDFs dominated over PCDDs in particulate samples. Di- to pentachlorinated biphenyls were dominant homologs in the particulate samples. MonoCBs were the dominant homolog in stack gases from the kiln back end, and homolog concentrations decreased with increasing chlorine numbers. Mono- and diCNs accounted for 48-98% of PCNs. The estimated toxic equivalents of stack gas emissions of PCNs, classified as new persistent organic pollutants under Stockholm Convention, were unexpectedly higher than those of PCDD/Fs and PCBs. A mass balance indicated that all of the toxic equivalents were reduced by this cement kiln system. The highest 2,3,7,8-PCDD/F output is with clinker.

[More] Little is known about pollution in urban snow and how aerosol and gaseous air pollutants interact with the urban snowpack. Here we investigate interactions of exhaust pollution with snow at low ambient temperature using fresh snow in a temperature-controlled chamber. A gasoline-powered engine from a modern light duty vehicle generated the exhaust and was operated in homogeneous and stratified engine regimes. We determined that, within a timescale of 30 min, snow takes up from the exhaust a large mass of organic pollutants and aerosol particles, which were observed by electron microscopy, mass spectrometry and aerosol sizers. Specifically, the concentration of total organic carbon in the exposed snow increased from 0.948 ± 0.009 to 1.828 ± 0.001 mg/L (homogeneous engine regime) and from 0.275 ± 0.005 to 0.514 ± 0.008 mg/L (stratified engine regime). The concentrations of benzene, toluene and 13 out of 16 measured polycyclic aromatic hydrocarbons (PAHs), particularly naphthalene, benz[a]anthracene, chrysene and benzo[a]pyrene in snow increased upon exposure from near the detection limit to 0.529 ± 0.058, 1.840 ± 0.200, 0.176 ± 0.020, 0.020 ± 0.005, 0.025 ± 0.005 and 0.028 ± 0.005 ng/kg, respectively, for the homogeneous regime. After contact with snow, 50-400 nm particles were present with higher relative abundance compared to the smaller nanoparticles (<50 nm), for the homogeneous regime. The lowering of temperature from 25 ± 1 °C to (-8) - (-10) ± 1 °C decreased the median mode diameter of the exhaust aerosol particles from 69 nm to 57 nm (p < 0.1) and addition of snow to 51 nm (p < 0.1) for the stratified regime, but increased it from 20 nm to 27 nm (p < 0.1) for the homogeneous regime. Future studies should focus on cycling of exhaust-derived pollutants between the atmosphere and cryosphere. The role of the effects we discovered should be evaluated as part of assessment of pollutant loads and exposures in regions with a defined winter season.

Picomolar inhibitors of carbonic anhydrase: Importance of inhibition and binding assays

Authors: Smirnovienė, J; Smirnovas, V; Matulis, D (2017) Analytical Biochemistry 522:61-72. HERO ID: 3603720

[More] The Ki of carbonic anhydrase (CA) inhibitors is often determined by the stopped- flow CO2 hydration assay, the method that directly follows the inhibition of CA enzymatic activity. However, the assay has limitations, such as largely unknown concentration of CO2 and the inability to determine the Ki below several nM. The widely used direct binding assay, isothermal titration calorimetry, also does not determine the Kd below several nM. In contrast, the thermal shift assay can accurately determine picomolar affinities. New equations estimating CO2 concentration were developed for the determination of kcat and KM of CA I and CA II. The inhibitor dose-response curves were analyzed using Hill and Morrison equations demonstrating that only the Morrison model is applicable for the determination of tight-binding inhibitor Ki. The measurements of interactions between ten inhibitors and seven CA isoforms showed the limitations and advantages of all three techniques. Inhibitor 6 exhibited the Kd of 50 pM and was highly selective towards human CA IX, an isoform which is nearly absent in healthy human, but highly overexpressed in numerous cancers. Combination of inhibition and binding techniques was necessary for precise determination of CA-high-affinity inhibitor interactions and future drug design.
