    Abstract

    Sewage sludge (SS), an underutilized but valuable resource for agriculture, contains essential nutrients, such as phosphorus. In Japan, where dependence on imported fertilizers is high and global price fluctuations persist, using SS as fertilizer presents a sustainable alternative aligned with circular economy goals. This review analyzes Japan’s current efforts to repurpose SS, focusing on technological developments and key policy initiatives that promote safe and effective application. Selective phosphorus recovery technologies mitigate resource depletion, while holistic approaches, such as composting and carbonization, maximize sludge utilization for agricultural applications. Government-led initiatives, including public awareness campaigns, quality assurance standards and research support, have facilitated the adoption of sludge-based fertilizers. To contextualize Japan’s position, international trends, particularly in the EU, are also examined. These comparisons reveal both common strategies and areas for policy and technological advancement, especially regarding regulation of emerging contaminants. By integrating national case studies with global perspectives, the study offers insights into the economic, environmental, and social benefits of SS reuse, contributing to Japan’s goals of resource self-sufficiency and carbon neutrality, while also informing broader sustainable agriculture transitions worldwide.

    Submarine groundwater discharge (SGD) has recently been recognized as an influential factor in coastal ecosystems; however, little research has been conducted on its effects on coastal fish diversity. To investigate the relationship between SGD and fish diversity, we conducted a survey at the coastal island scale using the environmental DNA (eDNA) method. Our findings indicate that fish species richness and functional richness peak at stations with high SGD. Environmental variables, such as salinity, dissolved inorganic nitrogen (DIN) concentration, and SGD, significantly influence fish diversity. Carnivore fish richness was negatively correlated with salinity, while planktivore fish richness was positively correlated. Additionally, SGD and DIN concentrations were found to be crucial in shaping omnivorous and pelagic communities, respectively. This study highlights the role of SGD in enhancing nutrient conditions favorable for diverse fish communities and demonstrates the effectiveness of eDNA metabarcoding for rapid marine biodiversity assessment. These findings provide valuable insights for coastal ecosystem monitoring and management.

    A short-term study was conducted to investigate the effects of additions of rice husk products on nitrous oxide (N2O) and carbon dioxide (CO2) emissions from paddy soil at different soil moisture contents. Soil amended with raw rice husk (RR, 2% on a dry weight basis), rice husk char (RC, 2%), rice husk ash (RA, 2%) or no amendment (CT) was incubated at 40%, 60%, or 80% water-holding capacity (WHC) in a 100-mL bottle for 120 h. Results showed that N2O emission was lower at 40% WHC compared with other WHC treatments. At 60% and 80% WHC, N2O emissions peaked at 24 h of incubation in most treatments. The highest emission of N2O was recorded in the RR addition at 80% WHC. Additions of RC and RA decreased cumulative N2O emissions from soil at 24 h (by 24% at 60% WHC and 51% at 80% WHC for RC, and 90% at 60% WHC and 80% WHC for RA) compared with the CT treatment. Regardless of the soil moisture content, RR enhanced cumulative CO2 emission for 120 h, whereas no significant difference was detected among RC, RA and CT treatments (P > 0.05). Our short-term results indicated that application of rice husk char or ash to soil reduced N2O emission, whereas direct incorporation of rice husk into soil enhanced CO2 and N2O emissions.

    In previous studies, a system consisting of catch crop cultivation and lactate fermentation was proposed in order to reduce greenhouse gas emission and nitrate infiltration from agricultural field. The system also has aims of recovering nutrient and producing lactate from catch crops to gain profitable products. In this research evaluation of the amount of greenhouse gas emission, nitrogen load to water environment and break-even point of introducing the lactate fermentation system of catch crop were conducted. As a result, increased amount of greenhouse gas emission from the whole system is larger than the decreased amount of N2O gas emission from agricultural field by catch crop. Most of the nitrogen load from agricultural fields cleaned up by catch crop is discharged as waste water from lactate production process. This means non-point source pollution in the agricultural fields is transformed to point source pollution through the system. Evaluation results showed the system could help to reduce the nitrogen load on water environment using advanced wastewater treatment. From the evaluation of the production cost, we found that nutrients extracting system in the previous stage of lactate fermentation is relatively advantageous than other systems. It was found that the break-even point of the system is greater than 105tDryWeight of catch crop, which means it is greater than 18ha of cultivation area of catch crop.

    Greenhouses are usually irrigated after cropping to remove accumulated salts in the topsoil. Nitrate remained in the soil is reported to be transported to groundwater due to the irrigation, resulting in high nitrate concentration in ground or surface waters. The present study evaluated the effect of a catch crop (dent corn) on leaching losses of nitrogen and phosphorus during a fallow period (catch crop cultivation, salt removal irrigation and reductive soil disinfection) in a farmer's eggplant greenhouse in Okayama, Japan, in 2010 and 2011. Nitrogen leaching was greatly reduced owing to the nitrogen uptake by the catch crop with compared to the control (p < 0.01). Differences of nitrogen losses during the fallow period between treatments were 12.2 g m-2 in 2010 and 5.4 g m-2 in 2011, probably due to different contents of mineral nitrogen remained in the soil after eggplant harvests. On the other hand, phosphorus leaching was not significantly different between treatments (p > 0.05). The effect of phosphorus uptake by the catch crop may be masked because of the large amount of mineral phosphorus accumulated in the soil. Our results clearly showed that catch crop growth during a fallow period reduced nitrogen leaching in the eggplant greenhouse.

    To understand the phenomena occurring in Lake Biwa and predict the effects of measures for improving water quality, constructing a simulation model that can calculate the hydrological and material cycle and reaction process in the basin with high accuracy is the most effective way. In this study, a Lake Biwa Basin simulation model with the integration of three components of land, lake flow, and lake ecosystem is constructed and named "Lake Biwa Basin Hydrological and Material Cycle Simulation Model". Distributed and 3-dimensional models are adopted; these models can simulate water quality and quantity unsteadily by considering weather, social conditions, and so on. As a result, river discharge and quality in main rivers, such as Yasu River and Hino River, and water temperature, average quality and seasonal variation in the lake are adequately calculated. On the other hand, it is insufficient to calculate water quality of the time series and distribution in Southern Lake; thus, it is a future challenge to evaluate spatial-temporal lake water quality precisely.

    Mires are loosing their natural state as a result of human activities. Recently natural Sphagnum mires in Hokkaido, Japan, have been disappearing as a result of the proliferation of alders. Here we show that such proliferation is caused by the inflow of phosphorous compounds as non-point pollutants. Those phosphorous compounds flow in from agricultural fields around mires. The constituents of groundwater or surface water make alders proliferate rapidly. Phosphorous, a typical non-point-polluting nutrient, contributes to the growth of alders, which assimilate atmospheric nitrogen.

    The concentrations of PCBs in sea water and blue mussels ranged from 0.5 to 4.0 ng · l-1 (mean ± S.D.: 1.8 ± 0.6 ng · l-1) and from 3.1 to 69.8 ng · g-1 -wet (24.0 ± 19.0 ng · g-1-wet), respectively, in the Seto Inland Sea. The main homologues of PCB in seawater and blue mussels were T4CBs and H6CBs, respectively, and their content ratios to total PCB were 40∼50%. Homologues with high chlorine content accumulated in blue mussels. By principal component analyses associated with the homologues of PCB in seawater, blue mussels and sediment, it was clearly shown that the sea area in Osaka Bay and Harima-nada were mainly contaminated with low-chlorine-content homologues of PCB which were mainly used in condenser and heating fluid, and that the other sea area was mainly contaminated with high-chlorine-content homologues which were mainly used in paints and varnish. More detailed analyses were possible by the principal component analyses with selected and important isomer data.

    Effects of nitrification on BOD were evaluated with two kinds of batch experiments, and the problems caused by N-BOD were discussed with descriptions of test manuals, experimental data and literature review. The main results drawn in this study are as follows:(1) most of water analysis manuals do not clearly describe nitrification on BOD test is an interference nor the matter to be measured, (2) ammonium nitrogen in dilution water causes a positive error in BOD test, and can overestimate N-BOD values more than two times, (3) BOD values measured with present methods can not express the pollution level because of N-BOD appearance during the purification development. As a conclusion, it is recommended that oxygen consumption by nitrification should be eliminated from the contents of BOD, and the test procedure should adapt an inhibition process for nitrification in BOD measurement.

    The mass change of nitrogen in Lake Biwa was shown, and its cycle was discussed and compared with the input/output loading. Nitrogen exists at 10.5X103 ton in average, and its minimum and maximum mass are 7.6X103 ton, 13.4X103 ton, respectively. Its average mass is equivalent to 133% of the annual input loading, resulting in 1.6 months of residence time, which is shorter than 5.5 years of hydraulic retention time. This indicates that nitrogen in the lake is removed by settling onto the lake bottom or denitrification, and the removed mass is estimated to be 71% of the input loading. Phytoplanktons mainly utilize ammonium nitrogen in epilimnion whose mass is only 1% of the total mass in the lake. rather than other inorganic nitrogen amounting to more than ten-fold of ammonium nitrogen. During the stratification period, almost all decomposed nitrogen in the organic matter is oxidized into nitrate, and half of them is likely to be removed by denitrification.

    The estimation of material mass in bodies of water such as lakes provides much information on water quality formation mechanism since it enables evaluation of mass balance in the body of water examined. However, such estimation is difficult, because water quality is not uniform and a precise water quality survey is actually difficult in a large lake. In this paper, mass estimation methods are proposed and compared with each other. In each method, material mass in Lake Biwa, Japan was estimated based on water quality data at 75 points in the lake. The spline technique that interpolates the concentration value in 500X500X1m-size mesh in the lake with a σ value of 0.3 was selected as the most suitable estimation method. Judging from the N/P ratio, mass values estimated by this technique were more reliable than those reported previously. Nitrogen and phosphorus are present in Lake Biwa at 7.6-13X103 tonN and 190-340 tonP, respectively, and their averages in 20 surveys from 1995 until 2000 were 11X103 tonN and 230 tonP, respectively.

    Aquatic macrophytes form a "system" consisting of the macrophytes themselves and periphytons attached to them. The system has a significant role in purifying water. In this study, we evaluated such water purification functions of macrophytes-periphytons "system", as removing nutrients of the river water prior the river flowing into a lake. Using the data obtained by a field survey and laboratory tests, we made a model of the water quality purification by macrophytes and the periphytons. As a result, we found (1) the "system" of aquatic macrophytes and periphytons play a role as "catalysis" to suspend the dissolved nutrients, and (2) a physical purification function by the aquatic macrophytes which act as a filter to remove suspended solid from the water. Also, we clarified the efficiency of these functions at the water surface.

    Catch crop cultivation followed by flood irrigation simultaneously realized the reduction of nitrogen leaching and removal of salts accumulated in the topsoil of greenhouse horticulture. Polysaccharides in the corn biomass cultivated as a catch crop was easily hydrolyzed, and the L-lactate fermentation using sugars derived from the biomass was demonstrated. Around 80% of phosphorus in the corn biomass was recovered by soaking powdered biomass in distilled water and calcium addition to the extract. These results demonstrated that the proposed system was effective for the prevention of nitrate groundwater pollution and resource recovery.

    Monitoring is a fundamental step to understand water quality conditions in lakes, and many lakes have been storing a huge amount of water quality data. However, these past records are not effectively used. This research project aims to develop a new water quality database system, which possesses almost all data recorded in a target lake with functions to use them skillfully, and satisfies not only the general public, but also specialists. Lake Biwa was chosen as the research lake.
    Then, past and present investigation projects in Lake Biwa were surveyed and their water quality data were collected and analyzed.
    The results indicate these investigations have various and different patterns on their investigation methods; the number of sampling stations ranges 1 to 5, that of depths ranges 1 to 12, that of times in a year ranges 1 to 365, and that of measured items ranges 8 to 100 more. The whole projects identified 86 different sampling stations and 44 different depths in the lake. The variety of investigation methods suggested that simple spread sheet can not handle the whole data systematically, and that the use of a relational database application software is needed. Then, Access 2000 was introduced to organize all of the data.
    The constructed database consists of one main table, two sub-main tables and seven minor explanatory tables, and has stored 670,000 WQI data for 50,000 samples from 15 survey projects. Its application softwares were also developed with the help of VBA (Visual Basic for Application) for general users who are not familiar to Access. This system has high flexibility on the data management and application, so that further extension of the system can be easily achieved.
