“…For example, the relative concentration of cyclic dodecane in KV1 is approximately 4 times that of KV2 and about 10 times that of KV3. From previous research done by Fu et al, 2022, various companies apply cyclic dodecane in search of hydrocarbons as a solution to nonpolar organic compounds, stabilizers, temporary sealants, and more so as a water repellant, thus easing the transport and protection of solutes on deeper aqueous surfaces during the extraction of hydrocarbons [55]. These findings are in total agreement that cyclic dodecane is being applied during mining in the Kerio Valley in search of hydrocarbons despite its persistent and potential to bioaccumulate in the environment, which may cause serious environmental and public health problems.…”

Currently, groundwater is largely becoming the main source of fresh water in most developing countries. However, various deleterious impacts resulting from anthropogenic activities beneath the earth’s surface have significantly affected groundwater quality, as evidenced in several areas endowed with mineral and hydrocarbon deposits, agricultural activities, and industrial processes. The possible etiological impacts may include cancer and genetic aberrations which result from the toxic effects of organic waterborne contaminants ingested by humans and animals over time. The motivation behind this study was to identify and determine the concentration profiles of various organic pollutants in the wells located along the Kerio Valley water basin near the exploratory wells for hydrocarbons and mining activities. Therefore, this study is necessary in unraveling the level of organic contaminants in the sampled borehole water, which can then be extrapolated to cover other boreholes within the Kerio Valley basin. The study was carried out during the dry season of December 2022. The water samples from the boreholes were extracted using a solid phase extraction procedure and characterized using a gas chromatograph interfaced with a mass selective detector. The findings indicate that benzene derivatives which were mainly xylenes, 1,3,5-trimethylbenzene, 1-ethyl-3-methylbenzene, 1-methyl-2-propylpentylbenzene and polycyclic aromatic hydrocarbons such as naphthalene, phenanthrene, fluoranthene, azulene, and pyrene were found in most of the boreholes sampled. Furthermore, long-chain hydrocarbons were present in all groundwater samples with varying concentrations. The concentration of benzene derivatives ranged from 2.84 to 20.47 ppm. However, polycyclic hydrocarbons exhibited the highest concentrations of all organic pollutants, with pyrene giving a concentration of 23.14 ppm, fluoranthene (18.54 ppm), phenanthrene (14.13 ppm) and anthracene (11.06 ppm). According to the findings reported in this study, most of the borehole water in the Kerio Valley basin is contaminated and may be unsafe for drinking. Most of the reported concentration levels were several times higher than the standards of the U.S. Environmental and Protection Agency. However, it is necessary to develop a policy framework on the assessment and monitoring of water quality in the region and propose urgent measures to ensure a clean water supply for the benefit of residents.

“…External stimuli-responsive fluorescent materials are of great interest because of their promising utilization in optoelectronic devices, sensors, photopatterning, biomedical delivery, and therapy systems [1][2][3][4][5][6][7][8][9][10][11][12][13]. A number of studies have been reported on the design of organic, inorganic, and organic-inorganic hybrid systems that respond to external or internal stimuli such as light, heat, force, magnet, electricity, specific chemicals, etc [5,[14][15][16][17][18][19][20][21][22]. For instance, chemical combination of photochromic compounds and organic fluorophores can be extended to the development of photoluminescent organic materials capable of responding to various stimuli (such as light wavelength, temperature, etc) [23][24][25][26][27][28].…”

We report the design of pyrene-substituted azobenzene chromophores and their assembly into flat aggregates capable of repeated switching of their absorption and emission properties in response to light and heat. The introduction of a relatively longer butoxy linker between the pyrene and azobenzene (AzBuPy) resulted in the production of more than 90% of cisazobenzene at the photostationary state of ultraviolet (UV) light, as determined by UV-visible absorption and 1 H NMR spectral data. Flat petal-shaped micrometer-sized structures formed in highly polar DMF-H2O mixtures did not experience severe disassembly even after sufficient UV light irradiation, and showed excellent photoswitching performance. In addition, we investigated light and heat responses of DPA@AzBuPy aggregates assembled from hydrophobic fluorophore (9,10-diphenylanthracene: DPA) and AzBuPy mixtures.

Investigations into the effective, fast, and economically viable remediation of soils polluted with petroleum-derived products are still relevant. The vegetative pot experiment was conducted at the Didactic-Experimental Garden greenhouse (NE, Poland, 53.759° N, 20.452° E) on loamy sand (LS) and sandy loam (SL) soils. Its main research objective was to assess the effectiveness of biochar (B), halloysite (H) and alginite (A) in the biological regeneration of contaminated soil diesel oil (DO) and petrol (P). The assessment was conducted by determining the magnitude of the adverse impact of these xenobiotics on the growth and development of Zea mays, as well as the activity of seven soil enzymes. The impact of the tested contaminants and sorbents was assessed based on the impact factors (IF) of DO and P, as well as B, H, and A on Zea mays biomass and enzymatic activity of the soil. Soil contamination with petroleum-derived products disrupted the growth and development of Zea mays. DO had a stronger inhibitory effect on plant growth compared to P. Zea mays cultivated in LS, which was less resistant to the effects of these contaminants compared to that cultivated in SL. The impact of DO and P on enzyme activity depended on the soil texture. DO stimulated enzyme activity in LS and SL, while P only did so in LS. All remediation substances, and biochar in particular, led to an increase in plant biomass in the DO-contaminated soils. Both biochar, halloysite and alginite also improved the biochemical quality index (BA) of SL and LS. Despite the unquestionable remediation potential of the analyzed sorbents, their highest efficacy can only be achieved by their application on soils with physicochemical properties corresponding to their characteristics, which is a valuable guideline for further research.
