Safety profiling of technical lignins originating from various bioresources and conversion processes. Heliyon 2024; 10:e32131. [PMID: 38988522 PMCID: PMC11233868 DOI: 10.1016/j.heliyon.2024.e32131] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2023] [Revised: 05/24/2024] [Accepted: 05/28/2024] [Indexed: 07/12/2024] Open
Abstract
In this work, a set of eight technical lignin samples from various botanical origins and production processes were characterized for their chemical composition, higher heating value, size distribution, dust explosion sensitivity and severity, thermal hazard characteristics and biodegradability, in further support of their sustainable use. More specifically, safety-focused parameters have been assessed in terms of consistency with relating physico-chemical properties determined for the whole set of technical lignins. The results emphasized the heterogeneity and variability of technical lignins and the subsequent need for a comprehensive characterization of new lignin feedstocks arising from novel biorefineries. Indeed, significant differences were revealed between the samples in terms of hazards sensitivity. This first comparative physico-chemical safety profiling of technical lignins could be useful for the hazard analysis and the safe design of the facilities associated with large scale valorisation of biomass residues such as lignins, targeting "zero waste" sustainable conversion of bioresources.

Abstract
Ready biodegradation is the primary biodegradability of a compound, which is used for discriminating whether a compound could be rapidly and readily biodegraded in the natural ecosystems in a short period and has been applied extensively in the environmental risk assessment of many chemicals. In this study, the effects of 24 molecular properties (including 2 physicochemical parameters, 10 geometrical parameters, 6 topological parameters, and 6 electronic parameters) on the ready biodegradation of 24 kinds of synthetic aromatic compounds were investigated using the OECD 301B CO2 Evolution test. The relationship between molecular properties and ready biodegradation of these aromatic compounds varied with molecular properties. A significant inverse correlation was found for the topological parameter TD, five geometrical parameters (Rad, CAA, CMA, CSEV, and N c), and the physicochemical parameter K ow, and a positive correlation for two topological parameters TC and TVC, whereas no significant correlation was observed for any of the electronic parameters. Based on the correlations between molecular properties and ready biodegradation of these aromatic compounds, the importance of molecular properties was demonstrated as follows: geometrical properties > topological properties > physicochemical properties > electronic properties. Our study first demonstrated the effects of molecular properties on ready biodegradation by a number of experiment data under the same experimental conditions, which should be taken into account to better guide the ready biodegradation tests and understand the mechanisms of the ready biodegradation of aromatic compounds.

Abstract
The main aim of the European Union Water Framework Directive (WFD) (2000/60/EC) is to protect rivers, lakes, coastal waters and groundwaters (EC 2000). The implementation of the WFD requires monitoring the concentration levels of several priority pollutants such as nonylphenol ethoxylates (NPEOs) and nonylphenol (NP) in the area of EU. The present practices for determining the concentration levels of various pollutants are, in many respects, insufficient, and there is an urgent need to develop more cost-effective sampling methods. A passive sampling tool named Chemcatcher was tested for monitoring NPEOs and NP in aqueous media. These environmentally harmful substances have been widely used in different household and industrial applications, and they affect aquatic ecosystems, for example, by acting as endocrine disrupting compounds. The suitability of different receiving phases which were sulfonated styrene-divinylbenzene reversed phase polymer (SDB-RPS), standard styrene-divinyl benzene polymer (SDB-XC) and C-18 (octadecyl) was assessed in laboratory and field trials. The effect of a diffusion membrane on the accumulation of studied compounds was also investigated. The SDB-XC and C-18 receiving phases collected the NPEOs and NP most effectively. The water flow affected the accumulation factor of the studied substances in the field trials, and the water concentrations calculated using sampling rates were tenfold lower than those measured with conventional spot sampling. The concentration of the analytes in spot samples taken from the sampling sites might be higher because in that case, the particle-bound fraction is also measured. The NPEOs readily attach to suspended matter, and therefore, the total concentration of such compounds in water is much higher. Also, the spot samples were not taken daily but once a week, while the passive samplers collected the compounds continuously for 2- or 4-week time periods. This may cause differences when comparing the results of those two methods as well. Both techniques can be applied for monitoring the concentration levels at different sampling sites, but the calculated and measured analyte concentrations in surrounding water are not necessarily comparable with each other. More experiments are still needed to study the effect of hydrological issues and humic substances on the accumulation of chemicals. However, the Chemcatcher passive sampler gives valuable information about the mean concentration levels of studied compounds during 2- or 4-week sampling period. This is important for comparison of annual monitoring results, especially in sampling sites with rapidly fluctuating concentrations.

Abstract
The European Union Water Framework Directive (WFD; 2000/60/EC) is an important piece of environmental legislation that protects rivers, lakes, coastal waters and groundwaters (EC 2000). The implementation of the WFD requires the establishment and use of novel and low-cost monitoring programmes, and several methods, e.g. passive sampling, have been developed to make the sampling process more representative compared to spot sampling. This review considers passive sampling methods focusing mainly on a passive sampler named Chemcatcher®, which has been used for monitoring several harmful compounds in aquatic environments. Also, the sample treatment and analysis of nonylphenol ethoxylates (NPEOs) and nonylphenol (NPs) from water using solid phase extraction (SPE) is briefly summarized. The procedure of Chemcatcher passive sampling is quite similar to that of the SPE extraction since it concentrates the studied compounds from water as well. After sampling, the accumulated substances are extracted from the receiving phase of the sampler. The concentrations of NPEOs and NPs are currently monitored by taking conventional spot samples; SPE can be successfully used as a pretreatment procedure. Chemcatcher® passive sampling technique is a simple and useful monitoring tool and can be applied to new chemicals, such as NPEOs and NPs in aquatic environments.

Abstract
BACKGROUND, AIMS, AND SCOPE Currently, elemental chlorine-free (ECF) and totally chlorine-free (TCF) bleaching systems are widely used for pulp production. Low and medium molecular weight lignin break-down products are known to have harmful effects on the environment. According to some recent results, also high molecular weight (HMW) material consisting mainly of lignin and carbohydrates may cause toxic effects to the environment. For these reasons, toxicity and structure studies of HMW materials are of great importance. This investigation is a part of a larger project to obtain more structure information of HMW materials and toxicity of ECF and TCF bleaching effluents. Size-exclusion chromatography (SEC) has been commonly used for the characterization of organic macromolecules such as lignin, but to our knowledge, no reports have appeared dealing with the comparison of SEC of ECF and TCF bleaching liquors. The aim of the present study was to get more information about the molecular weight distribution (MWD) of HMW fractions of waste liquors from ECF and TCF bleaching sequences by SEC. METHODS The MWDs of organic materials dissolved during different stages of ECF bleaching (O-D-EOP-D-ED) and TCF bleaching (O-Z-Q-P-Z-Q-P-P) of softwood (Pinus sylvestris) kraft pulp were determined and compared by SEC. All effluent samples from the above bleaching stages were ultrafiltrated using a membrane with a cutoff value of 1,000 Da. SEC was performed on high and also low molecular weight fractions and non-fractionated effluents. In the SEC experiments, a Superdex 75 column was used with 0.1 M NaOH solution as the eluent. Standards used for calibrating the SEC system were albumin, carboanhydrase, cytochrome C, tannic acid, dehydrodiacetovanillone, and vanillin. RESULTS AND DISCUSSION The chromatograms of liquors from TCF bleaching stages vary more than those from ECF bleaching. Peroxide and chelating stages contained mostly high molecular weight (HMW) matter whereas chlorine dioxide and ozone stages had more low molecular weight compounds. The lignin content in HMW matter was higher than in stages that consisted of low molecular matter. Bleaching effluents contained the highest amounts of HMW material, mainly lignin, in the beginning of the sequences; the amounts decreased towards the end of the bleaching sequence. CONCLUSION Determinations of MWD by the SEC method showed that effluents from the TCF sequence contained more HMW material than those from the ECF stage. This might be due to peroxide stages (P) that dissolve HMW lignin effectively. However, the molecular weights of ozone stages (Z) were very low compared to other stages. Chlorine dioxide stages also dissolved mostly low molecular weight lignin. Ultrafiltration of bleaching liquors showed that high molecular weight fraction also included some low molecular weight compounds and vice versa. High polydispersity and high lignin content correlated with the amount of HMW material in ECF and TCF bleaching stages. RECOMMENDATION AND OUTLOOK Our liquor samples were studied by using a UV detector commonly used for lignin preparations; in upcoming investigations, it will be interesting to determine carbohydrates such as hemicelluloses. The results are applicable in papermaking in order to improve commonly used bleaching procedures, to test new potential bleaching systems, and to study chemical behavior of HMW materials in various bleaching liquors. The present results also form a good basis for toxicity measurements of ECF and TCF bleaching effluents and for more comprehensive spectroscopic and chromatographic experiments with samples taken from various bleaching stages. From the behavior of liquors studied, it appears that our other structure investigations by spectroscopic and chromatographic (NMR, Py-GC/MS, etc.) methods mostly correlate well with the present results.

Abstract
Mexel(R)432 is an anionic surfactant used as biocide in the cooling water system of power plants for biofouling reduction. Refrigeration waters from power plants do not usually follow, prior to their discharge to sea, any treatment aimed to eliminate biocides and this can have negative consequences on the aquatic fauna nearby. The effects of different concentrations of the antifoulant Mexel(R)432 (0.5, 1 and 2mgL(-1)) on osmoregulation (osmolality and Na(+)/K(+)-ATPase activity) and stress parameters (cortisol, glucose, and lactate) were assessed in juveniles of the flatfish Solea senegalensis. Gill histopathology and alterations due to oxidative stress (increased lipid peroxidation, LPO, levels) at branchial and hepatic levels were also considered. Other parameters tested were the antioxidant enzymes (catalase, CAT; glutathione peroxidase, GPX; and glutathione reductase, GR), xenobiotic metabolism defenses involved in detoxification (carboxylesterase, CbE; 7-ethoxyresorufin O-deethylase, EROD; and glutathione S-transferase, GST) and the neurotransmitter acetylcholinesterase (AChE) activity. Significant variations in osmoregulatory parameters, histological lesions and decreased branchial Na(+)/K(+)-ATPase activity were observed in exposed fish. Other gill biomarkers presented little or no significant variations in relation to controls. In contrast, hepatic parameters, such as CAT activity, were inhibited while EROD activity was initially elevated but after longer exposures it recovered basal values. These results suggested that under our experimental protocol exists toxic associated to Mexel(R)432 exposures.

Abstract
Photolysis of octylphenol ethoxylates Triton X-100 (TX) in water under simulated sunlight conditions was investigated in the presence of Fe(III)-oxalate complexes. The results showed that Fe(III)-oxalate complexes mediated TX degradation followed the first-order kinetics and the photolysis efficiency was dependent on the pH, Fe(III) concentration, Fe(III)/oxalate ratio and initial TX concentration. The active oxygen species generated by photolysis of Fe(III)-oxalate complexes were monitored by electron paramagnetic resonance (EPR) method using 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) as the spin-trapping reagent. The steady-state concentration of OH radicals was 8.33x10(-14)M and the rate constant of TX reaction with OH radical was 1.29x10(9)M(-1)s(-1) under our experimental conditions. The degradation products were analyzed by the high-performance liquid chromatography-electrospray ionisation-mass spectrometry and the degradation mechanisms of TX in the presence of Fe(III)-oxalate complexes was proposed. The OH radical can react with the alkyl chain, ethoxy (EO) chain and the aromatic ring of TX molecule during TX photolysis process. The main degradation pathway of TX involves the OH radical addition to the aromatic ring and the cleavage of the alkyl chain followed by combination with OH radical. The OH radical also attacks the polyethoxylated chain to generate short polyethoxylated chains or formyl ethoxylates.
