EXPLORING CYTOLOGICAL ASPECTS OF SOCKET HEALING OPTIMIZATION AFTER ATYPICALREMOVAL OF THE THIRD LOWER MOLAR

This study aims to investigate the cytological characteristics of socket healing after atypical removal of the lower third molar, utilizing osteoplastic synthetic material in conjunction with platelet-rich gel and plasma enriched with thrombocyte factors, to enhance local osteogenesis. Materials and Methods For this comparative clinical study, smears of alveolar content were collected following atypical extraction of the lower third molar. Cell elements were quantified for cytological analysis. Data collection utilized a template developed in Microsoft Excel version 16.34. Statistical processing was performed using RStudio 2023.03.1 Build 446 (Posit Software, PBC). Smears were air-dried, fixed in a 1:1 mixture of alcohol and acetone for 5 minutes, stained first with May-Grünwald’s methylene blue (15 minutes), followed by Romanowsky-Giemsa’s azure-eosin stain (30 minutes). Smear images were captured with the Leica morpho densitometric complex: DM 1000 microscope, DFC-320 camera, images were obtained in jpg format at 400x magnification. Results The study encompassed 30 patients divided into control and experimental groups. Cytological analysis was conducted on the 2nd, 5th, and 10th days of post- operation. In both groups, on the 2nd day, alveolar smears showed the presence of erythrocytes (n = 6) and neutrophils (n = 2). On the 5th day, the experimental group exhibited neutrophils (n = 3) and abundant cocci microflora (n = 6). On the 10th day, epitheliocytes (n = 8) primarily indicated proliferation. Conclusions The obtained results underscore the effectiveness of employing osteoplastic synthetic material in combination with plateletrich gel and plasma enriched with thrombocyte factors for enhancing local osteogenesis following atypical removal of the third molar. This approach demonstrates significant elevation in epithelialization activity, fibroblastic activity, and other markers of the reparative process in comparison to the control group.

Remnant polarization and structural arrangement in P(VDF-TrFE) electrospun fiber meshes affect osteogenic differentiation of human mesenchymal stromal cells

Many tissues and cells are influenced by mechano-electric stimulation, thus the application of piezoelectric materials has recently received considerable attention in tissue engineering. This report investigated electrospun fiber meshes based on poly(vinylidenefluoride-co-trifluoroethylene) [P(VDF-TrFE)] as instructive biomaterials for osteogenic differentiation of human mesenchymal stromal cells (hMSCs). The influence played by methyl ethyl ketone (MEK), used as a solvent in place of dimethylformamide (DMF)/acetone mixture, and the effect of rotating velocity of the electrospinning collector on fiber morphology, mechanical and piezoelectric properties were studied. The solvent had noticeable effects on morphology and piezoelectric properties of electrospun fibers, with MEK outperforming DMF/acetone. By increasing the collector velocity up to 4000 rpm, the fiber diameter reduced and the mutual alignment of the fibers increased, corresponding to enhanced mechanical properties and piezo-active β-phase content. However, as a consequence of the diverse mechanical properties of random and aligned fibrous architectures, which ultimately affected the piezoelectric properties, randomly-oriented fibers exhibited higher remnant piezoelectric properties (Vout and d31 piezoelectric coefficient) than aligned ones. On these scaffolds, hMSCs showed an excellent capability of early osteogenic differentiation, leading to high calcium production. Fiber surface topology, fiber mesh morphology and remnant piezoelectric properties played a determinant role on hMSC osteogenic commitment.

Understanding the dewatering of fermentation-based 1,3-propanediol with acetone before cyclohexanone synthesis

Acetone can be produced by microbial fermentation using Clostridium acetobutylicum (acetone-n-butanol-ethanol fermentation, ABE fermentation), but it provides a mixture of acetone, 1-butanol, and ethanol. N-butanol and ethanol can be used as biofuels, but high-value applications of acetone generally require upgrading. Bio-based 1,3-propanediol is more readily produced by fermentation and separated at higher titers and has been used industrially. Therefore, the coupled upgrading of the two fermentation products can provide another avenue for high-value utilization of acetone. In this paper, salting-out extraction of 1,3-propanediol with acetone was carried out, and 1,3-propanediol and acetone would spontaneously form an organic phase, thus reducing the energy consumption in the 1,3-propanediol separation process. As the double alkylation reaction of acetone with equivalent 1,3-propanediol would generate cyclohexanone, the extraction of 1,3-propanediol with acetone can provide new insight into the process intensification (removing water, salt and water concentrated in the aqueous phase) for the 1,3-propanediol separation and conversion.

3D Printing of Glass Micro-Optics with Subwavelength Features on Optical Fiber Tips.

Integration of functional materials and structures on the tips of optical fibers has enabled various applications in micro-optics, such as sensing, imaging, and optical trapping. Direct laser writing is a 3D printing technology that holds promise for fabricating advanced micro-optical structures on fiber tips. To date, material selection has been limited to organic polymer-based photoresists because existing methods for 3D direct laser writing of inorganic materials involve high-temperature processing that is not compatible with optical fibers. However, organic polymers do not feature stability and transparency comparable to those of inorganic glasses. Herein, we demonstrate 3D direct laser writing of inorganic glass with a subwavelength resolution on optical fiber tips. We show two distinct printing modes that enable the printing of solid silica glass structures ("Uniform Mode") and self-organized subwavelength gratings ("Nanograting Mode"), respectively. We illustrate the utility of our approach by printing two functional devices: (1) a refractive index sensor that can measure the indices of binary mixtures of acetone and methanol at near-infrared wavelengths and (2) a compact polarization beam splitter for polarization control and beam steering in an all-in-fiber system. By combining the superior material properties of glass with the plug-and-play nature of optical fibers, this approach enables promising applications in fields such as fiber sensing, optical microelectromechanical systems (MEMS), and quantum photonics.

Enhanced Side-Illumination of Etched Polymer Optical Fiber (POF)-Incorporated Woven Polyester (PET) Fabrics

The textile industry has been weaving polymer optical fibers (POFs) into plane fabric for many years for lighting and decoration. To apply POF-incorporated fabrics in a larger field of application, it is necessary to improve the side illumination of POF-incorporated fabrics. It has been reported that the chemical etching method is one method to enhance the illumination of POFs, while there is little research related to the application of chemical etching to enhance the illumination of POF-incorporated fabrics. In this work, the end emitting POFs (EEPOFs) were used as weft yarns, and polyethylene terephthalate (PET) yarns were used as warp yarns. The POF-incorporated woven PET fabrics were successfully fabricated with a 1/3 twill structure and then treated with a mixture of acetone and methanol (volume ratio: 1:1) for 1 min. The morphology and side illumination of etched POF-incorporated PET fabrics were investigated. As a result, the acetone/methanol mixture destroyed the cladding layer of EEPOFs, and the luminance of etched POF-incorporated PET fabrics was increased by more than 50 %. Besides, acetone/methanol etching resulted in a higher side illumination attenuation behavior.

Controlled aggregation of unsymmetrical amphiphilic perylene diimide derivative into nanosheets

The self-assembly behavior of perylene diimide (PDI) derivatives has been manipulated to produce nanostructures with exceptional optoelectronic properties. The size and dimension of the aggregates determine their roles in various applications, which are determined by the structure and functionality of the PDI derivatives, including the solvent system in which self-assembly occurred. Herein, we report the synthesis of two new and distinct amphiphilic unsymmetric PDI derivatives. These PDIs contain alkyl chains of varying lengths at one of the imide positions, whereas the other imide position contains a fixed L-alanine substituent. In 90 % hexane or decalin in chloroform, these PDIs were aggregated to form ribbon-like morphologies. In contrast, in a polar solvent system comprised of mixtures of water and acetone, both PDI derivatives self-assembled differently to form distinct morphologies. As the synthesis of PDI-based two-dimensional supramolecular nanosheets has been challenging and also rarely mentioned in the literature, here, we have found that one of the PDI derivatives with long alkyl chain self-assembled to nanosheets in 90 % water/acetone solvent mixture.

PM2.5-bound polycyclic aromatic hydrocarbons (PAHs): quantification and source prediction studies in the ambient air of automobile workshop using the molecular diagnostic ratio

The presence of polycyclic aromatic hydrocarbons (PAHs) in the atmosphere has been linked to health concerns, including cancer. Automobile workshops are significant contributors to PAH emissions due to their operations. Hence, this investigation aimed to identify and quantify the sources of PM2.5-bound PAHs in the ambient air of automobile workshops in Benin City, Nigeria, using molecular diagnostic ratios. PM2.5 samples were collected from 60 automobiles over 1 year, during the rainy (April to November) and dry (December to March) seasons of 2019. Sample collection utilized a low-volume air sampler with quartz filter paper, and extraction was performed using a 1:1 mixture of acetone and dichloromethane. The analysis involved an HP Agilent Technology 6890 Gas Chromatography (GC) system with a flame ionization detector. The annual average concentrations of PM2.5-bound PAHs in Benin City were 269.87 ± 249.32 ng/m3 (dry season) and 216.30 ± 204.89 ng/m3 (wet season). Molecular diagnostic ratios, such as Fl/(Fl + Py), An/(An + Phe), BaP/(BaP + Chry), BbF/BkF, InP/(InP + BghiP), and BaA/(BaA + Chr), aided in identifying PAH sources. Gasoline combustion, diesel combustion, traffic emissions, and emissions from automobile panel welders were found to be the primary sources of PAHs near vehicle workshops. These findings provide crucial insights for developing effective strategies to reduce emissions and protect public health in the air surrounding automobile workshops in Benin City.

Getting the phase consistent: The importance of phase description in balanced steady-state free precession MRI of multi-compartment systems.

Determine the correct mathematical phase description for balanced steady-state free precession (bSSFP) signals in multi-compartment systems. Based on published bSSFP signal models, different phase descriptions can be formulated: one predicting the presence and the other predicting the absence of destructive interference effects in multi-compartment systems. Numerical simulations of bSSFP signals of water and acetone were performed to evaluate the predictions of these different phase descriptions. For experimental validation, bSSFP profiles were measured at 3T using phase-cycled bSSFP acquisitions performed in a phantom containing mixtures of water and acetone, which replicates a system with two signal components. Localized single voxel MRS was performed at 7T to determine the relative chemical shift of the acetone-water mixtures. Based on the choice of phase description, the simulated bSSFP profiles of water-acetone mixtures varied significantly, either displaying or lacking destructive interference effects, as predicted theoretically. In phantom experiments, destructive interference was consistently observed in the measured bSSFP profiles of water-acetone mixtures, supporting the theoretical description that predicts such interference effects. The connection between the choice of phase description and predicted observation enables unambiguous experimental identification of the correct phase description for multi-compartment bSSFP profiles, which is consistent with the Bloch equations. The study emphasizes that consistent phase descriptions are crucial for accurately describing multi-compartment bSSFP signals, as incorrect phase descriptions result in erroneous predictions.

Computation of Ultrasonic Speed in Binary Liquid Mixture of Acetone and Carbon tetrachloride using Empirical Theories at Different Temperatures

Experimental ultrasonic velocities of binary liquid mixture of acetone and carbon tetra chloride at temperatures 286.15 K, 289.15 K and 293.15 have been evaluatedat 2 MHz as a function of molar concentrations. The experimental values were compared with various theories for analysis of ultrasonic velocity in binary liquid mixtures such as Nomoto theory (NOM), ideal mixing relation (IMR) of Van Dael andVangeel, Impedance Relation (IDR), Rao’s Specific Velocity Method (Rao) and Junjie’s relations (JR). Chi-square test and average percentage error were applied to investigate the relative applicability of these theories to the present systems. The variation of thermo acoustical parameters of the systems with the mole fraction has been discussed in term of molecular interactions.

A Review on Methods of Cenosphere Separation from Fly Ash

Cenospheres are valuable material contained inside the fly ash. Its low weight, low density, and high strength made it very versatile and can be used in various fields. The way of separating the cenosphere from the fly ash consists of two categories, wet and dry separation. For wet separation, it involves submerging the fly ash inside a mixture made either by pure acetone, pure water, or a mixture of water and acetone with different mixing ratios before stirring the mixture. The cenospheres, floating on top of the mix due to low density, can be collected and dried. The dry separation technique involves putting the fly ash into a cyclone separator at a constant velocity. The fly ash will then move into the bottom of the cyclone. Particles can also be separated by diameter sizes by sieving. By manipulating various parameters, cenosphere yield may differ. This paper is written to help gain more understanding on cenosphere properties and its separation method.

From Hansen solubility parameters to new anti-icing, viscoelastic sponges of terpolymer of tetrafluoroethylene, vinylidenefluoride, and hexafluoropropylene (THV)

THV, a relatively new hydrophobic polymer, has found wide application from explosives to sensors. Therefore, we decided to determine its Hansen Solubility Parameters (HSP) – one of the most important parameters in polymers processing. Studied 41 liquids can be divided into four groups: very good solvents (1), causing gelation (2) causing soaking or color change (3), and inert (4) and HSP values were calculated. We also proposed green chemistry solvents for THV. At the next stage, two solvents from group 1, and two from group 2, and their mixtures, were selected to determine the effect of a solvent on the THV sponge properties. The sponges were characterized by total pore volumes, porosity, mechanical properties, and surface morphology. Moreover, thermal, and anti-icing properties were studied for different film thicknesses. This holistic approach, together with a theoretical description of the icing process via a dynamic growth angle model, makes it possible to relate the sponge morphology to thermal, mechanical, hydrophobic, and anti-icing properties, showing that the studied sponges are strongly hydrophobic or superhydrophobic with a water contact angle (WCA) as large as 160° for THVAC. Considering anti-icing properties, total freezing time, delaying of recalescence, and possible ice removal by wind or vibration, the sponge obtained from the mixture of DMF and acetone (THVDMFAC) seems to be optimal. This sponge has the highest Young’s modulus, high thermal stability, and anti-freezing properties thus, it can be successfully applied in anti-icing covers in, for example, wind turbine blades.

Binary mixture of subcritical water and acetone: a hybrid solvent system towards the production of lignin nanoparticles

A hybrid solvent system based on binary subcritical water/acetone mixtures demonstrates production of uniform lignin nanoparticles while reducing the dependence on high volumes of organic solvent.

Enhanced Detection of Benzo[a]pyrene in Olive Oil through Low Temperature Liquid-Liquid Extraction Coupled with Constant Energy Synchronous Fluorescence Spectroscopy

Refined processed olive oil can indeed become significantly contaminated with polycyclic aromatic hydrocarbons (PAHs). To assess exposure to these contaminants, benzo[a]pyrene (B[a]P) is utilized as a marker due to its known carcinogenicity in humans. The European Commission has established a maximum limit of 2 μg kg-1 for B[a]P in edible oils. However, the analysis of trace amounts of B[a]P in a complex matrix like olive oil poses a persistent challenge. In this study, we have developed a low-temperature liquid-liquid extraction method in combination with constant energy synchronous fluorescence analysis for the determination of B[a]P in olive oil samples. The analyte was extracted from the olive oil using a mixture of acetonitrile and acetone. The performance of fluorescence measurements was evaluated by carefully considering the effects of solvent, temperature, acetone quenching, and slit width for monochromators. The proposed method demonstrates a linear range from 0.8 to 3.2 μg kg-1, with limits of detection and quantification of 0.04 and 0.80 μg kg-1, respectively. Precision and trueness assessments revealed relative standard deviations of less than 10% and recovery rates ranging from 103 to 112%. This method presents an efficient and rapid alternative to sample preparation procedure that minimizes organic solvent consumption.

Dispersive liquid-liquid microextraction as a novel enrichment approach for compound-specific carbon isotope analysis of chlorinated phenols.

Compound-specific isotope analysis (CSIA) via gas chromatography-isotope ratio mass spectrometry (GC-IRMS) is a potent tool to elucidate the fate of (semi-)volatile organic contaminants in technical and environmental systems. Yet, due to the comparatively low sensitivity of IRMS, an enrichment step prior to analysis often is inevitable. A promising approach for fast as well as economic analyte extraction and preconcentration prior to CSIA is dispersive liquid-liquid microextraction (DLLME) - a well-established technique in concentration analysis of contaminants from aqueous samples. Here, we present and evaluate the first DLLME method for GC-IRMS exemplified by the analysis of chlorinated phenols (4-chlorophenol, 2,4-dichlorophenol, and 2,4,6-trichlorophenol) as model compounds. The analytes were simultaneously acetylated with acetic anhydride and extracted from the aqueous phase using a binary solvent mixture of acetone and tetrachloroethylene. With this method, reproducible δ13C values were achieved with errors ≤ 0.6‰ (n = 3) for aqueous concentrations down to 100 μg L-1. With preconcentration factors between 130 and 220, the method outperformed conventional liquid-liquid extraction in terms of sample preparation time and resource consumption with comparable reproducibility. Furthermore, we have demonstrated the suitability of the method (i) for the extraction of the analytes from a spiked river water sample and (ii) to quantify kinetic carbon isotope effect for 2,4,6-trichlorophenol during reduction with zero-valent zinc in a laboratory batch experiment. The presented work shows for the first time the potential of DLLME for analyte enrichment prior to CSIA and paves the way for further developments, such as the extraction of other compounds or scaling up to larger sample volumes.

ANALYSIS AND RESTORATION OF GRECO-ROMAN POTTERY IN EGYPT

The research aims to identify features of the industry and assess the pottery damage through various examinations and analyses, such as examination by polarised microscope (PLM), examination by Scanning Electron Microscope with Energy Dispersive X-ray unit "SEM-EDX", analysis by X-ray diffraction powder XRD, and thermal analysis TGA. Archaeometric features of archaeological pottery were identified. The used clay is Nile Clay; the additives are sand, limestone powder, pottery powder (grog), and straw. The moulding technique is the hand and potter wheel technique. The surface treatment is a red wash and slip layer. The burning atmosphere is oxidising for the first and second pottery pieces and reducing for the third and fourth pottery pieces. The burning temperature is about 816°C for the first sample, 887°C for the second sample, 706°C for the third sample, and 651°C for the fourth sample. The texture is medium to coarse fabric for the first sample; the second sample fabric is fine; and the third and fourth samples have a coarse texture. The research proved that the pottery objects suffer from some different damage aspects such as fracture, loss of some parts, lack of strength, weakness, cracking, soil sediments, soot spots and black core, and salt crystallisation (chloride, sulphate, carbonate, and phosphate salts). The research proved the use of a mixture of distilled water, acetone, and ethyl alcohol at a ratio of 1:1:1, respectively, for removing clay soil deposits. EDTA is used to remove lime deposits. Nano-silica at a concentration of 0.5% is used to strengthen archaeological pottery by spraying. Paralloid B 82 dissolved in trichloroethylene at a concentration of 50% in assembling the pottery sherds; it is preferable to display it in the museum at a temperature of 20°C and a relative humidity of 55:60%.

Selective chemical etching for termination layer control of BaSnO3 and 2DEG formation at the LaInO3/BaSnO3 interface

An ex situ chemical etching method was developed to achieve a SnO2-terminated surface in BaSnO3 films. An SnO2-terminated surface is crucial for the formation of a (LaO)+/(SnO2)0 interface structure to form the two-dimensional electron gas (2DEG) state at the LaInO3 (LIO)/BaSnO3 (BSO) interface. By employing a 9:1 mixture of acetone and water, the etching rate of the surface barium oxide (BaO) layer could be effectively controlled, taking advantage of the solubility of BaO in water. To determine the optimal etching conditions, we investigated the relationship between the etching time and the resulting 2DEG conductance. The optimum times for maximizing the conductance of the 2DEG state were found to be 90 s on SrTiO3 substrates and 40 s on MgO substrates, generating a higher conductance than the in situ SnO2 dusting method reported earlier. The surface properties before and after the chemical etching were analyzed by angle reserved x-ray photoelectron spectroscopy.

Facile chemical hydrophobization of thin-layer plates by vapor deposition of methyltrimethoxysilane for reversed-phase chromatography

Reversed-phase chromatography is based on a polar mobile phase and an apolar stationary phase. This separation mode is regularly used in planar (thin-layer) chromatography, and the necessary plates are commercially available. We investigated the preparation of hydrophobic plates for thin-layer chromatography by chemical vapor sorption of methyltrimethoxysilane directly onto a normal-phase plate. For this, a commercial normal-phase plate is simply exposed to the vapors of the reagent in a closed vessel. The obtained plates were characterized by infrared spectroscopy and dynamic water vapor sorption, which reported an extensive conversion of free hydroxyl groups by the reagent. The obtained plates were hydrophobic with a water contact angle close to 135°. The extent of hydrophobization precluded the use of pure water as an eluent while mixtures with organic solvents were perfectly adequate. The plates’ chromatographic performance was compared with that of C18 and paraffin-coated plates. For this, a set of parabens was separated with mixtures of acetone and water. The height of a theoretical plate was similar for the hydrophobized and the C18 plates (50–90 µm) and larger for the paraffin-coated ones. In contrast to the C18 plate, the hydrophobized and the paraffin-coated plates showed some selectivity for the analyte pair n-butylparaben and iso-butylparaben, which indicates a separation mechanism with the potential for regioselectivity.

Simultaneous measurements of kinetic and scalar energy spectrum time evolution in the Richtmyer–Meshkov instability upon reshock

The Richtmyer–Meshkov instability (Richtmyer, Commun. Pure Appl. Maths, vol. 13, issue 2, 1960, pp. 297–319; Meshkov, Fluid Dyn., vol. 4, issue 5, 1972, pp. 101–104) of a twice-shocked gas interface is studied using both high spatial resolution single-shot (SS) and lower spatial resolution, time-resolved, high-speed (HS) simultaneous planar laser-induced fluorescence and particle image velocimetry in the Wisconsin Shock Tube Laboratory's vertical shock tube. The initial condition (IC) is a shear layer with broadband diffuse perturbations at the interface between a helium–acetone mixture and argon. This IC is accelerated by a shock of nominal strength Mach number $M = 1.75$ , and then accelerated again by the transmitted shock that reflects off the end wall of the tube. An ensemble of experiments is analysed after reshock while the interface mixing width grows linearly with time. The kinetic and scalar energy spectra and the terms of their evolution equation are calculated and compared between SS and HS experiments. The inertial range scaling of the scalar power spectrum is found to follow Gibson's relation (Gibson, Phys. Fluids, vol. 11, issue 11, 1968, pp. 2316–2327) as a function of Schmidt number when the effective turbulent Schmidt number is used in place of the material Schmidt number that controls equilibrium scaling. Further, the spatially integrated scalar flux follows similar behaviour observed for the kinetic energy in large eddy simulation studies by Zeng et al. (Phys. Fluids, vol. 30, issue 6, 2018, 064106) while the spatially varying scalar flux exhibits back scatter along the centre of the mixing layer and forward energy transfer in the spike and bubble regions.

Regulation of the existing state of Cu species in high water-toletant CuOx-Mn3O4 for VOCs mixtrue catalytic oxidation

The existing state of Cu species play a crucial role in the activity of CuOx-Mn3O4 catalysts. In this work, CuOx-Mn3O4 with CuO loading on and Cu partially substituted Mn in spinel were successfully synthesized by adjusting the doping strategy of Cu. The CuOx-Mn3O4-IPM with substituted Cu, which derived from Cu-doped Mn-MOF-74, exhibited the largest specific surface area, the highest Mn3+ and oxygen vacancies, together with enhanced low temperature reduction performance. And thus it showed excellent catalytic activity for the mixture of toluene and acetone. The addition of a minute quantity of substituted Cu (2.60 %) significantly improved the catalytic activity of MnOx (T90%[Tol] and T90%[Ace] was increased by 23 ℃ and 37 ℃, respectively). The results of the in situ DRIFTS showed that the reaction pathway of the mixture still follows that of single toluene and single acetone over CuOx-Mn3O4-IPM.

Acaricides Application Rates and Residue Levels in Homemade Sprays, Soil and Water from the Southern Ewaso Nyiro River in Kajiado West Sub County, Kajiado County, Kenya

Acaricides used in controlling ectoparasites (ticks) is the most preferred and economical sound conventional mode of tick eradication. The study aimed at determining acaricide application rates and residue levels in the homemade cattle sprays, soils within the spraying sites and water from the nearby southern Ewaso Nyiro River. The livestock drink river water which is used for domestic purposes. Acaricide residues levels analyzed were those used by farmers in for homemade cattle sprays. The cattle sprays and soil samples were collected from ten selected homes spraying sites randomly from 138 willing farmers in the May and November representing wet and dry seasons respectively in 2018. The sprays were collected after farmers prepared them in the usual way before spraying their animals. The livestock farmers’ ways of mixing and application of acaricides after normal preparation was assessed. The different acaricides identified were analysed for active ingredient levels after preparation using Gas chromatography-Mass spectrometry. Water samples were collected from six sites adjacent to the homes where the sprays were prepared since some homes were found to share the same water drawing area. Solvents used were triple distilled for samples extractions. The homemade sprays and water samples were extracted using dichloromethane while Soxhlet method for soil in a mixture of acetone and hexane in the ratio of 1:3. Samples were concentrated using a rotary evaporator and the clean-up through aluminium oxide chromatographic glass column. Refrigerator was used for sample storage while a Hewlett-Packard Agilent Gas chromatography system equipped with a mass selective detector was used for quantification of acaricide residues levels. Out of the nine acaricides reported by farmers through the questionnaire, three namely amitraz, cypermethrin and deltamethrin were detected in the homemade cattle sprays and soil samples. Amitraz levels ranged from 884±25.3 to 12,236±14.54 µg/L, Cypermethrin was at 3,834±80.2 to 11,972±74.0 µg/L with Deltamethrin at 3,879±33.2 to 12,298 ±82.1 µg/L in the dry while amitraz was at 5,430±96.10 to 11,634±107.2 µg/, 8,975± 103.7 to 10,383±562 µg/L for Cypermethrin while Deltamethrin was only used by home 3 at concentration of 4,781± 125.8 µg/L in the wet seasons in homemade cattle sprays. In the soil, acaricides were in the range of 3,129±98.7 to 10,641±144.2 µg/kg for amitraz, 3,041±33.15 to 8,654±141.2 µg/kg, Cypermethrin and 1,341±58.06 to 8,167±16.4 µg/kg Deltamethrin in dry and 3,875±97.3 to 7,905±184.2 µg/kg amitraz, 4,832±86.7 to 8,694±146.9 µg/kg Cypermethrin. Deltamethrin was only used by home 3 at a level of 2,367±76.9 µg/kg in the wet season. The analysis revealed that homemade cattle sprays in the sub-county had low levels of amitraz, cypermethrin and deltamethrin than those recommended by the manufacturers of 50,000-400,000 µg/L, indicating that the acaricides were over diluted leading to the observed tick re-occurrence in Kajiado West Sub County.
