    ABSTRACT

    Pesticide contamination in freshwater ecosystems poses a significant threat to water quality and aquatic life, potentially disrupting entire food webs. Fluxametamide (FMT), a novel insecticide regarded as safe for nontarget species, has not been extensively studied in aquatic environments, raising concerns about its potential toxicity to organisms such as Daphnia magna (D. magna). This study investigates the acute toxicity of FMT, the potential of ultrafine bubbles (UFB), and the associated morphological alterations on D. magna. This result revealed that acute toxicity tests showed FMT is very toxic to D. magna, with LC50 24–48 h values of 0.051 and 0.013 µg/L, respectively. However, UFB has the potential to reduce the toxicity of FMT by twofold compared to control water in D. magna. Morphological analysis in the presence of UFB revealed carapace and body damage at high concentrations and prolonged exposure. In contrast, control water resulted in pesticide accumulation throughout the body, leading to more rapid tissue destruction even at lower concentrations and shorter exposure durations. In conclusion, UFB has the potential to alleviate the toxic effects of FMT by modifying its chemical structure, enhancing detoxification mechanisms, and minimizing its overall detrimental effect on D. magna. These findings represent an initial report on the effect of UFB on FMT toxicity in D. magna, providing essential theoretical foundations for the application of FMT in ecotoxicology.

    Abstract
    Recent advances in high-resolution X-ray computed tomography (HRXCT) enable comprehensive qualitative and quantitative analysis of wood microstructure. This study combines micro-CT imaging with advanced segmentation to characterize Moringa oleifera L. stem anatomy. Qualitative analysis revealed distinct tissue boundaries, with grayscale images differentiating xylem vessels (bright) from parenchyma (dark) based on density. Reconstructed 3D volumes showed alternating parenchyma-fiber bands, while watershed segmentation delineated pores and Kuwahara filtering preserved structural details. Quantitative results demonstrated spatial heterogeneity: total porosity measured 22.3 ± 2.9 % versus 2.4 ± 1.9 % to 3.7 ± 0.2 % in ROIs. Pore density varied inversely (0.7 ± 0.3 to 1.4 ± 1.0 μm−3), with average pore sizes ranging 0.3 ± 0.6 to 1.9 ± 0.2 μm2. Strong correlations existed between porosity and pore diameter (r = 0.99) or % area (r = 0.95), showing morphology governs void fraction. Parameters exhibited symmetric distributions (skewness ≈ 0) with light tails (kurtosis < 3). CT resolved wall thickness variations (0–15 mm), linking microstructure to mechanical properties. The non-destructive approach provides unprecedented 3D quantification of Moringa wood’s structural adaptations, supporting applications in biomaterials and fluid transport systems.

    ABSTRACTThe increased use of disinfection products, particularly hand sanitizers containing triclosan, has raised significant environmental concerns, including antimicrobial resistance (AMR) in microorganisms. This study compares the effectiveness of ozone solutions and micro‐nano bubbles (MNB) solutions in addressing AMR. The findings indicate that MNB, particularly due to its stable generation of hydroxyl radicals (HO•), achieved significantly higher bacterial disinfection rates, with over 95% of bacteria killed after only 3 h. This suggests that MNB could be a potent alternative for efficient bacterial inactivation in water treatment systems. Additionally, ozone solutions have been found to be more effective in reducing antimicrobial‐resistance genes presence, particularly at optimized concentrations (50% ozone, 2.5 mg/L). This targeted control over antimicrobial‐resistance genes represents an innovation in managing antibiotic resistance in environmental waters, indicating that ozone at specific concentrations could reduce antimicrobial‐resistance gene proliferation. Moreover, MNB solutions show little to no adverse effect on bacterial DNA structure, even at high concentrations. The combination of these two advanced oxidation treatments offers a promising perspective for disinfection technology, aiming for maximum antimicrobial‐resistance genes inactivation with minimal side effects, thereby exemplifying a more refined approach to ozone‐based disinfection.

  • Toxicity of triclosan, an antimicrobial agent, to a nontarget freshwater zooplankton species, Moina macrocopa               
    Thilomi Samarakoon; Takeshi Fujino
    Environmental Toxicology, Sep. 2023, [Reviewed]
    AbstractThe toxicity of triclosan (TCS) on the freshwater cladoceran Moina macrocopa was investigated by acute and chronic toxicity assessments followed by genotoxicity and oxidative stress response analyses. The 48‐h LC50 of TCS for ≤24‐h‐old M. macrocopa was determined as 539 μg L−1. Chronic exposure to TCS at concentrations ranging from 5 to 100 μg L−1 showed a stimulatory effect at low concentrations (≤10 μg L−1) and an inhibitory effect at high concentrations (≥50 μg L−1) on growth, reproduction, and population‐growth‐related parameters of M. macrocopa. The genotoxicity test results indicated that TCS concentrations ranging from 50 to 100 μg L−1 can alter individuals' DNA. Analysis of the antioxidant enzymes catalase (CAT) and glutathione s‐transferase (GST) demonstrated increased levels of these enzymes at high TCS concentrations. Our results indicated that TCS concentrations found in the natural environment have minimal acute toxicity to M. macrocopa. However, TCS at even low concentrations can significantly affect its growth, reproduction, and population‐growth‐related characteristics. The observed responses suggest a hormetic dose–response pattern and imply a potential endocrine‐disrupting effect of TCS. Our molecular and biochemical findings indicated that high concentrations of TCS have the potential to induce oxidative stress that may lead to DNA alterations in M. macrocopa.

  • Water Pollution and Pollution–Control Capacity in Chinese Provinces: Panel Estimations of Provincial Environmental Kuznets Curves

    China’s rapid industrialization and urbanization in recent decades have deteriorated its water resource quality. This study focused on water pollution in terms of the chemical oxygen demand (COD) and the levels of ammonia nitrogen in the industrial and household discharges of different Chinese provinces. Although the heterogeneity of environmental Kuznets curves (EKCs) from Chinese provinces has been studied, the positions of provincial EKCs (which reflect the province-specific pollution effects not affected by the provincial income levels) have not been investigated to date. Therefore, through a factor analysis of the heterogeneity of provincial pollution under the EKC framework, we investigated how the capacity shortage for pollution control contributes to the provincial pollution levels. We also evaluated the heterogeneity of the EKCs from the provinces in terms of their positions (not their shapes), using a fixed-effect model to extract the province-specific pollution effects. The capacity shortage for pollution control, as one of the pollution factors, accounted for (a) 30% of industrial COD and industrial ammonia nitrogen; (b) 60% of household COD; and (c) 80% of household ammonia nitrogen. Our results indicate that China still has a large capacity to mitigate water pollution via policies and by building the capacity for pollution control through the development and training of human resources.

    Abstract
    High–molecular-weight polymer coagulants are widely used in wastewater treatment combined with traditional inorganic coagulants to improve the solid–liquid separation efficiency. However, it is desirable to keep chemicals used in treatments at minimum levels for economic and safety reasons. This study aimed to increase the efficiency of two-stage electro- and chemical-coagulation treatment with a minimum chemical dosage for the separation of solids and liquid in dairy manure slurry for the safe composting of solids and safe discharge of wastewater. Accordingly, dairy manure slurry was treated with aluminum (Al) coagulants, such as polyaluminum chloride (PAC), aluminum chloride (AlCl3), and aluminum sulfate (Al2(SO4)3), PAC combined with the cationic polyacrylamide (CPAM), and PAC and CPAM combined with electrocoagulation (EC). Results revealed that PAC was the best among the Al coagulants evaluated for the reduction in turbidity in the liquid fraction at a dosage of 100 mg/L. PAC dosage was reduced to 40 mg/L when the treatments were combined with CPAM at a dosage of 40 mg/L, which was further reduced to 30 mg/L when treatments were combined with 5 min EC and 20 mg/L of CPAM dosage.

    Size-segregated concentrations of OC, EC, WSOC, and ionic components were measured for PM samples collected at three locations around Hanoi, Vietnam. On the day when high PM concentration was observed, secondary products increased, suggesting the possibility of transboundary pollution from China. Also, organic marker analysis showed the possibility of mixed combustion of biomass and plastic waste in addition to secondary generation on high-concentration days, and this tendency was remarkable even in ultrafine particles. On the other hand, the analysis of PAHs in atmospheric PM and suspended particles in rainwater revealed that PAHs in the atmosphere are transferred to the hydrosphere via rainwater. When image analysis was performed using a scanning microscope, some particulate matter considered to be derived from the atmosphere was confirmed in the sample of rainwater.

    Major sources of radioactive contamination for paddy field in Fukushima area could be the irrigation water from river water because radioactive concentration in river water seemed to be increasing. This research had conducted to quantify radioactive cesium amount in irrigation water and paddy soil. As a result of quantification, the total amount of radioactive cesium in irrigation water through one season showed less than 1 % of that residue in paddy soil.

    We present the results of the first investigation of the water and sediment
    properties and macroinvertebrate community at a 2nd order stream in Chin State, Myanmar. The concentrations of inorganic nitrogen and phosphorus measured in the rainy season are very high compared with those measured in the dry season. The first Myanmar Trichoptera list based on the literature and recently collected materials are made. It comprises 227 species in 68 genera and 28 families. Twenty-one species belonging to 15 genera and 10 families were recorded in Myanmar for the first time.
    We examined the knowledge and awareness of 200 respondents in two local townships, Mindat and Kanpetlet, regarding local environment issues and development requirements. Results indicated differences in knowledge and level of awareness between the two townships particularly regarding issues such as the reduction in fallow period, forest dependence, promoting tourism, protecting local identity and family planning requirements.

    Pulse Amplitude Modulation(PAM)method is used to evaluate photosynthesis activities for algae. In this study, estimation of primary productivity of stream bed periphyton was applied. Handy Fluor Cam was used to obtain horizontally two dimensional distributions. As a result, there is correlation between the minimum fluorescence yield Fo and the biomass for green algae and filamentous algae. There is relatively high correlation between the maximum fluorescence yield Fm and diatom. For direct measurement in field, the dark condition and enough amount of algal biomass are necessary.

    Covering the lake bottom, Charophytes have a substantial potential in purifying water in lakes. However, lack of research on water quality in charophyte dominant Japanese lakes as well as the disappearance of charophyte bed in Japan make it difficult to evaluate the efficiency of purifying water by charophytes in shallow lakes. Field observation we conducted at Myall lake is NSW, Australia, where the entire lake was covered with charophytes and the underlying gyttja layer, then chemicals of plant, gyttja, and water samples were analyzed in laboratory to clarify ecology of charophytes and effects on water quality based on their life style. Then, following are clarified.
    1)Charophytes inhibit disturbing the bottom sediment surface, and gyttja originated from charophytes are extremely fine and viscous, stabilizing the bottom surface against wind currents. Thus, the recovery of nutrient in the sediment to the overlying water is hampered.
    2) Gyttja is extremely soft, then is hard to anchor other submerged plants with high buoyancy. Thus the invasion of other plants is inhibited.
    3)Charophytes trap phosphate when they produce calcite using calcium in water. This system seems to be available even in Japanese lakes with relatively small calcium concentration.
    4)Gyttja is composed of extremely fine particles thus its layer is very anoxic. Thus, the interstitial water is rich in ammonium rather than nitrate. As phosphate concentration is low, thus the nitrogen and phosphorus ratio is very high. When charophytes uptake nutrient, they highly fractionate ammonium composed of light nitrogen rather than heavy one. Thus, the nitrogen stable isotope ratio of charophyte tissues becomes extremely low.

    In order to predict the growth responses for Aquatic plants in different age, water depths, climate condition, and any other environmental factors, Phragmites australis, Typha angustifolia, Zizania latifolia were studied in a natural stand in lake and pond in Japan. Eleocharis sphacelata, Baumea arthrophora, and Juncus ingens were also investigated in Australia.
    Summary of the main results are as follows.
    1)As for Phragmites australis, there is a clear variation between rhizome age-classes in belowground resources translocation patterns depending on the season.
    2)The growth was severely retarded by cutting combined with salinity, which was many implications for better management of Phragmites stands.
    3)The comparison of the growth performance of Phragmites across the geographic gradient relealed differences in phonological and growth/production traits.
    4)A dynamic growth model was developed for Typha latifolia and Typha angustifolia that took account of their vertical productive structures, life cycle, shoot height, leaf area and aboveground biomass.
    5)In contrast to other species, self-thinning of Zizania latifolia shoots reallocates some of the minerals contained in the dead shoots back to the rhizomes, which can be regarded as a strategy to replenish the reduced resources of the rhizomes. And, some submerged plant, Potamogeton perfoliatus, and two species of Charophytes were also investigated.

    1. Survey on Railway Transportation of Solid Waste
    Field surveys were carried out to investigate current situation of solid waste transportation by railway and technical and institutional problems were discussed.
    2. Study on wide-area transportation of solid waste from economic point of view
    Traditionally, "polluter pay principle" was the basis of solid waste management, which promoted local authorities to magage solid wastes inside municipality boudaries. In this study, problems related with wide-area management were analyzed form economic point of view. Also, selection of long-distance transportation methods and site selection method of treatment facilities were also analized.
    3. Study on environmental impact of large landfill sites
    Large-scale solid waste landfill with conventional pavement will lead to the change on micro-climate and causes temperature raise. However, water retainable blocks and pavements were proved to be able to maintain thermal condition at the same level as the natural soil. The effect of land surface improvement on the urban thermal condition was also investigated. In addition, application of water retainable blocks to roofing material was also investigated.
    4. Study on "Should-be picture" of solid waste transportation in wide area
    The role of railway transportation of solid waste was studies from the standpoint of health and environment. "Should-be picture" of wide-area railway transportation was also investigated.

  • Study on the effects of aquatic vegetation on foraging behaviour of planktivores in lakes

    In littoral zones of lakes, macrophytes have considerable structural variation and that provides protection to prey communities by hindering predator foraging. The swimming and feeding behaviour of a planktivore (Pseudorasbora parva) with their prey (Daphnia pulex) were studied in a series of laboratory experiments with varying densities of simulated submerged vegetation. Prey availability was varied from 0.5, 1, 2, 5, 10 and 25 prey.lィイD1-1ィエD1. As the stem density gradually increased, the predator's foraging efficiency decreased considerably relative to feeding in open water. Moreover, a good relation in feeding rate and swimming speed existed with the average stem distance to fish body length ratio. Abrupt reduction in feeding and swimming was recorded when fish body length ratio was near 0.7, which is approximately equal to one stride length of a fish.
    In fish, hunger increases the motivation to feed and also efficiency of feeding. After 36 hours of food deprivation, the feeding and swimming behaviour of Pseudorasbora parva was studied under different prey densities. The initial feeding rates showed marked variations in relation to prey availability. Under high densities the initial feeding rate of fish was higher and subsequently decreased faster, when compared to those feeding under low prey densities. At high prey densities, two factors are involved : that of high prey encounter rates and also the attainment of food satiation at a faster rate. Across all prey densities, the feeding rates of fish reached a plateau after satiation. The swimming speed was noted as being directly related to the level of satiation. After satiation, the fish fed at a steady rate irrespective of prey density. However, the swimming speed of fish varied significantly in relation to prey density. It was found that the maximum feeding rates depend upon and show a marked variation with average prey distance.
