Here, we investigated their bioaccumulation in an Indian tarantula, Theraphosidae spider Thrigmopoeus truculentus inhabiting mud embankments along a national highway in the Western Ghats mountains, and the soil contamination. Concentrations in soil were higher than the soil environmental quality criteria of different countries for Cd, Zn and Ni. Concentrations in whole-body of tarantulas (n = 7) were Zn > Se > [Cd, As, Pb, Ni] > In > total mercury (THg) > MeHg. Concentrations of Zn, Cd, Se, THg and MeHg were significantly higher (p < 0.05) compared to soil, suggesting biomagnification. Our work and the review of past data suggest that spiders can biomagnify Zn, Cd, Se, THg and MeHg; but not Pb, As, In and Ni. For As, Zn, Se, Cd, In and THg, correlations between concentrations in tarantula appendages and whole-body were significant (p < 0.05), suggesting that a non-lethal approach be explored where only appendages of larger tarantulas are analysed. Overall, the Theraphosidae species showed the potential to be used as an indicator of bioaccumulation, and their usefulness should be further explored.KEYWORDS: IndiaWestern GhatsTarantulapotentially toxic trace elements and methylmercurybioaccumulation AcknowledgementsMRB gratefully acknowledges the Goa State Biodiversity Board for permitting a limited collection of spider specimen for this experimental work.

The removal kinetics and adsorption isotherm of Zn by T. pubescens from an aqueous solution were evaluated. The results demonstrated the growth inhibition of fungus by an increase in Zn concentration. Zn concentrations of 10 and 20 mg L−1 in the medium caused an increase in the growth of fungus. Laccase production reduced at 100 and 200 mg L−1 of Zn. The kinetic parameters of Zn adsorption onto the biomass of fungus from aqueous solutions (containing 200 mg L−1 Zn) obtained by experiments at different contact times. The results indicated a trend of increasing Zn removal by fungus with the contact time, and it was well-described by the Intra-particle diffusion and Elovich models. The maximum removal of Zn was 67.1% at 7200 min, with a maximum sorption capacity of 44.7 mg g−1. The adsorption of Zn was well-fitted to the Freundlich and Langmuir sorption models. This study indicated an impact of a low concentration of Zn to increase laccase production and the feasibility of this fungus to remove Zn from aqueous solutions.KEYWORDS: Adsorption isothermTrametes pubescenskinetic of removalLaccase activityZinc AcknowledgementsThe authors would like to thank the Research council of Shahid Chamran University of Ahvaz for the support of this study (GN.

In order to determine their content and to evaluate the contamination level, 156 topsoil samples were collected in an area of 301.5 km2. The content of elements was determined by inductively coupled plasma-mass spectrometry. The results showed that the average content of Cu (42 mg/kg), Bi (1.5 mg/kg), Ag (0.44 mg/kg), and Au (2.7 μg/kg) exceeded their average content in European and world soils by 3.4 and 1.4 times; 3.0 and 7.5 times; 1.62 and 8.8 times and 2.7 and 1.8 times, respectively. The average Mo content (0.68 mg/kg) exceeded the average content in European soils by 1.09 times, while the average content in world soil was not exceeded. Copper levels exceeded the Dutch target value of 36 mg/kg in 152 km2 and the Dutch action value of 190 mg/kg in 6.2 km2 of the study area. The enrichment factor and geo-accumulation index values for the analysed elements indicate that their higher content is of anthropogenic origin, mainly due to lead and zinc mining and metallurgical activities in the study area. The quality of soils in the Mitrovica region varies from highly contaminated with copper and bismuth, with extremely high enrichment of Cu, Bi and Ag in the soils of the central zone (Zone I) and the urban soils of the cities of Zveçan and Mitrovica. Therefore, the establishment of a monitoring and treatment programme for contaminated soils in this zone would be necessary to protect human health .KEYWORDS: Soilpollutionenrichment factorgeo-accumulation indexMitrovica regionRepublic of Kosovo Author contributionsMA, RŠ and TS: conceptualisation and supervision of the project; MA and TS: writing of the manuscript.

The study analysed the concentrations of lead (Pb), copper (Cu), chromium (Cr), cadmium (Cd) and iron (Fe) in wetland soils and plants from 10 sites in the region. Pollution indices, including contamination factor, modified degree of contamination, Nemerow pollution index and pollution load index, were used to determine the extent of metal pollution in the study area, while transfer factors were calculated to assess the potential for metal transfer from soils to plants. The results showed that metal concentrations in wetland soils and plants varied widely depending on the location and the metal of interest, with some sites showing higher concentrations due to agricultural and mining activities. The pollution indices indicated that metal pollution was generally moderate to highly polluted in the study areas, with some metals showing higher potential for transfer from soil to plants than others. This study provides valuable insights into the extent and severity of metal pollution in some wetland soils and plants in Northern Nigeria.KEYWORDS: Wetlandspollution indicestransfer factorsource apportionmentNigeria AcknowledgementsThe authors are thankful to the management of Federal University Dutse especially the Laboratory division for providing the enabling environment and available equipment and reagents throughout this research to the team who worked for the success of this manuscript’s compilation.

Post the screening/washing/screening pretreatment, the content of total volatile solids escalated to 73.20%, while ash content reduced to 16.45%. Concurrently, lignin values surged to 30.12% as the biodegradability factor declined to 21%. The pretreatment decreased electrical conductivity from 11.60 to 1.32 DS/m. Employing a central composite design and response surface analysis pinpointed the optimal substrate combinations for carbon/nitrogen ratios of 35:1 and 25:1. The chosen combinations presented a high coefficient of determination (R2 = 0.9589, carbon/nitrogen ratio; R2 = 0.6584, pH), indicative of a robust statistical fit. Over a 45-day period, composting was conducted using bioreactors or biopiles, maintaining near-neutral pH values and temperatures slightly above ambient levels. The composting process reduced up to 94% of fecal coliforms in the 1:1 combination. Physicochemical analyses confirmed that the final product is a valuable compost-soil improver, with great potential for usage in organic agriculture, reforestation, and urban green spaces. Hence, this research underscores composting as an efficient technique in managing organic waste, including the emergent and seasonal Sargassum fluitans, thus addressing a pressing environmental concern with an innovative, effective solution.KEYWORDS: Central composite methodcompostingresponse surfacewaste AcknowledgementsWe appreciate the attention and kindness of those responsible for the ‘El Rodeo’ Ranch, a sheep meat and milk production unit.

The elements (Al, Ba, Co, Cr, Cu, Mn, Mo, Ni, Pb, Th, Ti, U and Zn), in their dissolved form in water, were measured by high resolution sector field inductively coupled plasma mass spectrometry. A validation approach was used in accordance with the requirements of ISO/IEC 17025 and following the Eurachem guideline. Taking this into account, the parameters selectivity, detection limit, quantification limit, linear interval, sensitivity, bias, recovery percentage, repeatability, reproducibility, and uncertainty were systematically assessed. Detection limits from 0.0014 to 0.2363 ng mL−1 were obtained. Recovery values from 82.3 to 100.6% for the water certified reference material (CRM) were achieved. Repeatability from 1 to 3% and reproducibility from 1 to 4.1% were hit. The expanded uncertainty associated with each result was estimated by identifying the main uncertainty sources. The potential of the proposed analytical procedure for water, based on the low detection limits obtained, allows the method to determine very low concentration levels in water, such as small variations in its concentration. This methodology can potentially be applied to all types of water, because most of the elements analysed are listed in the official regulations for water.KEYWORDS: WaterICP-SFMSmethod validationISO-17025uncertaintytrace elements AcknowledgementsTo Eng.

The study identified significant differences in metal concentrations (i.e. Ca, Mn, Fe) and non–metals (i.e. C, S) across sediment depths. Metal and non–metal concentrations in surface sediments (0–40 cm) were generally high. Compared with the sediment quality guidelines, all measured metals were within the ‘no effect’ level across different sites and depths, except for one site (i.e. Mambvumbvanyi pan). In contrast, enrichment factors showed that K, Ca and Mg were enriched in sediments across all the floodplain pans and depths. Principal component and cluster analyses indicated that various metals originated from different sources. Although a high concentration of metals was found in the topsoil, no potential detrimental effects on the aquatic systems could be observed. Based on the findings, this study provides a baseline overview of sediment metal pollution that can inform effective management of these floodplain wetlands systems.KEYWORDS: Floodplain pansRamsar wetlandsmetalssediment profilesgeo-accumulation indexenrichment factor AcknowledgementsWe are grateful to South African National Parks (SANParks) Scientific Services for research permits (SS287), as well as to Mr Aubrey Maluleke the Park Coordinator of Makuleke Contractual National Park for allowing us to conduct research on the Makuleke concession area.Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementAll the data collected during this research is presented in the manuscript.Credit authorship contribution statementLFM: Conceptualisation, Investigation, Data curation, Formal analysis, Writing – original draft, review & editing.
