Bioaccumulation factors (BAFs) are often applied to estimate the transfer of contaminants from soil to crops. However, they can vary widely and introduce uncertainty to exposure and risk estimates. We, therefore, aimed to quantify this uncertainty in a case study of an agricultural field with elevated soil concentrations of perfluorooctane sulfonic acid (PFOS) using literature-derived BAF versus measured concentrations of PFOS in corn (Zea mays L.) kernels and stover. PFOS was the predominant PFAS detected in soil and corn stover (<100 and 19 ng/g), and no detectable PFAS were identified in kernels. The median BAF (0.17) for PFOS was similar to that derived from a review of previous studies, while the maximum (0.2) was over an order of magnitude lower. Median PFOS concentrations in stover from our samples were comparable (16.60 ng/g) to those calculated using the literature-based BAF (16.28 ng/g). For cattle consuming stover, median and upper bound concentrations of PFOS in beef (30 ng/g) were similar and 60% lower using measured versus literature-derived BAF concentrations in stover. Finally, the central tendency exposure for children (27 ng/kg-bw/day) was similar using measured versus literature-derived BAF concentrations in stover and higher compared to adults (15 ng/kg-bw/day). Overall, these results indicate that (1) corn kernels accumulate little to no PFAS even when soil concentrations are elevated, (2) direct measurement of PFAS in crops can reduce uncertainty in exposure and risk assessment, and (3) PFOS can biomagnify via the soil-stover-cattle-human pathway and is found to pose a potential risk in our case study.","PeriodicalId":15732,"journal":{"name":"Journal of environmental quality","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145023453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have quantified yield losses due to delayed sowing and evaluated interannual yield variability caused by environmental and climatic factors. The results revealed that the southern regions had the highest Yp values but also the largest Yg values, which were strongly influenced by climatic factors. In contrast, the Brazilian Midwest had the lowest Yp yet minimal water-related Yg, with relatively stable yields over time; here, Yg were primarily due to crop management rather than climatic constraints. In northern macroregions, lower Yp was observed with moderate climatic influences. Delayed sowing reduced Yp across all macroregions, with the greatest losses occurring in regions with initially high Yp, particularly in the south. Each macroregion has unique environmental conditions that lead to different patterns of Yp, Ya (actual yield), and Yw. In the southern macroregions, Yg are primarily due to water constraints, indicating potential benefits of irrigation, while the Midwest, which has the lowest Yg, improved crop management practices offer the most significant opportunity for yield gains.","PeriodicalId":15732,"journal":{"name":"Journal of environmental quality","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145023484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ongoing research is investigating a variety of high organic matter (OM) and Al/Fe phases for use as amendments to reduce PFAS leaching from matrices including biosolids. Drinking water treatment residuals (DWTRs) have characteristics (e.g., high OM, oxalate-extractable Al (Alox), and/or oxalate-extractable Fe (FeOx) content) linked with PFAS retention and are widely available at low cost. We investigated sorption and desorption of a suite of eight PFAS, including sulfonates and carboxylates varying from C4 to C9, in biosolids amended with Al, Ca, and Fe DWTRs at rates from 2.5% to 10% wt/wt. Three biosolids were used: (1) high OM, low FeOx; (2) high OM, high FeOx; and (3) low OM, high AlOx. For all biosolids and DWTRs tested, amendment with 2.5% and 5% DWTR resulted in no significant increase of partition coefficient (Kd) value in sorption for the examined PFAS when compared to controls, and only a few inconsistent significances in desorption. However, at 10% DWTR, significantly increased Kd values were observed in both sorption and desorption in some of the DWTR-treated biosolids, particularly those treated with Al DWTR. These results suggest that DWTRs (especially Al DWTRs) can enhance the retention of PFAS, and that DWTR amendment rate appeared to be more influential on PFAS sorption and desorption than physical characteristics of the DWTRs and biosolids or PFAS properties.","PeriodicalId":15732,"journal":{"name":"Journal of environmental quality","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144956546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their nutrient balances changed differently over the past three decades. The Netherlands reduced its N and P balances dramatically, from 328 to 166 kg ha-1 and 35 to 4 kg ha-1, respectively, while Korea's balances remained unchanged with the highest levels in 2019 (230 kg N ha-1 and 46 kg P ha-1). To find solutions for Korea's persistent nutrient surpluses, changes in nutrient balances and related parameters were compared using OECD statistics. Despite Korea's efforts to reduce chemical fertilizer use, a 33% decline in agricultural land area and increased manure production offset the reduction. Conversely, the Netherlands rapidly decreased nutrient balances by reducing N and P inputs by 35% and 52%, respectively. Nutrient outputs in the Netherlands, primarily driven by forage harvest, were over twice as high as in Korea, helping lower its balances despite minor output declines. By the late 2010s, Dutch P input and output were nearly equilibrated, indicating no P surplus. As a result, the Netherlands has improved its nutrient use efficiency substantially, which inversely correlates with nutrient balance, but Korea has not shown considerable changes. Therefore, to address Korea's nutrient balances, nutrient inputs should be reduced while increasing outputs. Determining the level of nutrient inputs, coupled with advanced agronomic practices and technologies to improve nutrient use efficiency, is essential for achieving reductions in nutrient balances while enhancing crops and forage production.","PeriodicalId":15732,"journal":{"name":"Journal of environmental quality","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144956487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Metal bioconcentration factors and retranslocation percentages (RT%) were determined. Relationships between metals, between metals and sediment carbon, and metal retranslocation and bioavailability differed between the sites. Metals with high retranslocation percentages by plants, such as zinc and lead at La Parguera, suggest that plant-mediated stabilization processes can reduce immediate bioavailability but may pose latent risks under changing environmental conditions. Conversely, cadmium, with low retranslocation, and nickel, with high retranslocation and high bioavailability at Laguna Grande, indicate greater potential for biological uptake and ecosystem stress. Results suggest that differences in relationships between metals and between metals and carbon may help identify sources and effects of metals. Further research is needed to explore the direct physiological effects of metal exposure on plants and their implications for carbon storage and ecosystem health in mangrove-dominated systems.","PeriodicalId":15732,"journal":{"name":"Journal of environmental quality","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144956560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The model is based on leaching data obtained by multiplying the measured nitrate concentration below the root zone depth by the percolation calculated using a hydrological model, which together provides estimates of annual nitrate leaching from the root zone. However, this approach has some limitations, including redundancy and unclear error propagation in the relationship between nitrate concentration and percolation without considering seasonal variability. This study presents an approach to estimate the monthly distribution of nitrate concentration based on measurements of soil water samples taken with suction cells installed below the root zone. Our workflow includes screening algorithms to identify the most relevant predictors, testing the predictive performance, reducing the number of predictions for practical implementation, and evaluating the impact on the final nitrate leaching calculations. The workflow was applied to the suction cup measurement dataset in the NLES5 support database of field experiments. The results show that the regression tree-based Extreme Gradient Boosting algorithm effectively estimates monthly variations in nitrate concentrations without relying on percolation data, by using time, management, soil, and weather covariates such as month, spring mineral fertilization, main crop, winter crop, clay content, mean monthly temperature, and accumulated precipitation in the harvest year. A cross-validated error of 34% was achieved for nitrate concentration, and a correlation of 0.8 with nitrate leaching calculated from observed concentrations demonstrates a consistent description of the seasonal distribution of nitrate concentrations below the root zone.","PeriodicalId":15732,"journal":{"name":"Journal of environmental quality","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144956571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Policies designed to ameliorate eutrophication by limiting nutrient loadings to surface waters can reduce these GHG emissions and, in turn, reduce future climate damages (e.g., from heat stress, sea-level rise, etc.)-yet this benefit has not been considered in benefit-cost analyses of water quality policies. We address this gap by using a set of linked watershed, lake, and aquatic GHG models to estimate emission reductions from a large-scale nutrient management program in the America's largest estuary, the Chesapeake Bay. The modeling system predicts reductions in chlorophyll-a, total phosphorus, and GHG emission rates in waterbodies throughout the watershed, but those in the southern portion of the watershed are predicted to exhibit greater reductions than those in the north, likely due to strong climate (e.g., ice-cover duration) and land-cover gradients across the domain. We estimate climate benefits from changes in GHG emissions from these water bodies of over $300 million over the first 50 years of the program (2025-2075)-similar in magnitude to commonly quantified categories of water quality benefits. We then extrapolate our results to the third largest drainage basin in the world-the Mississippi-Atchafalaya River Basin-to estimate climate benefits of reduced GHG emissions from lakes and reservoirs in the basin resulting from a similarly stringent nutrient management policy. Our findings suggest that reductions in GHG emissions from nutrient management programs should not be overlooked when evaluating the societal benefits of such policies.","PeriodicalId":15732,"journal":{"name":"Journal of environmental quality","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144956497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ryegrass biomass across two harvests remained similar for all biochar treatments but was significantly lower than for the mineral fertilizer (KH2PO4) treatment. Significant differences were evident in P contribution from biochars and raw feedstocks, as well as in total P uptake rates between treatments. The readily available P contents of biochar and P-recovery rates in plant shoots were negatively correlated with pyrolysis temperature, which was especially pronounced for digestate-derived biochars. All materials except high-temperature biochar (600°C) had mineral fertilizer replacement values exceeding 50%, indicating substantial P-recycling potential. Biochars produced at 400°C and 500°C had a similar fertilizer value as their original feedstocks.

Public and private sectors at national and international levels are currently incentivizing farmers to adopt these practices to increase soil carbon (C) levels, thus helping to mitigate climate change. However, increasing soil C levels with an expectation of mitigating and adapting to climate change needs further evaluation. Reduced soil disturbance, retention of crop residues, planting cover crops, or diversification of crop rotations with perennials are indeed effective, especially in the long term (>10 years), in improving soil properties that enhance climate change adaptation, but not so much climate change mitigation. However, planting of cover crops, considered to be one example that represents conservation agriculture, is currently practiced on only 4.7% of cropland in the United States. Further, we question whether current programs that pay for C stored in soil are sufficient to incentivize farmers to change their operations due to the high cost to test soil C to validate their efforts. We propose that to promote wider adoption of sustainable conservation agricultural practices, and to make large-scale positive impacts through their use, farmers should be paid to \"do the right thing\" instead of paying them based on soil C accrual. The literature indicates that doing the right thing includes (1) continuous no- or minimum-soil disturbance, (2) permanent biomass soil cover, (3) biodiversity in crop rotations, and (4) applying or practicing these three principles on a continuous year-after-year basis. Paying farmers to \"do the right thing\" versus paying farmers for C credits will lead to much higher adoption rates of sustainable conservation agricultural practices by farmers. This will in turn lead to improved crop production and soil and environmental quality.","PeriodicalId":15732,"journal":{"name":"Journal of environmental quality","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144956523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
