Workshop: Runoff pH Influences Nutrient Removal Efficacy of Floating Treatment Wetland Systems

Abstract: Floating treatment wetlands (FTWs), a modified constructed wetland technology, can be deployed in ponds for the treatment of nursery and greenhouse irrigation runoff. The pH of nursery and greenhouse operation irrigation water varies from 3.3 to 10.4 across the United States. Water flow rate, plant species selection, and variable nutrient inputs influence the remediation efficacy of FTWs and may interact with the pH of inflow water to change nutrient remediation dynamics. Therefore, an experiment was designed to quantify the effect of pH on the growth and nutrient uptake capacity of three macrophyte species using a mesocosm FTW system. ‘Rising Sun’ japanese iris (Iris ensata), bushy bluestem (Andropogon glomeratus), and maidencane (Panicum hemitomon) were grown for two 6-week periods and exposed to five pH treatment levels representing the range of nursery and greenhouse irrigation runoff, 4.5, 5.5, 6.5, 7.2, and 8.5, for a total of 15 plant and pH combinations. Water was treated with either hydrochloric acid to decrease the pH or sodium hydroxide to increase the pH. The pH-adjusted solutions were mixed with 12 mg·L−1 nitrogen (N) and 6 mg·L−1 phosphorus (P) fertilizer (64.8 g·m−3 N and 32.4 g·m−3 P). Differences in pH impacted both N and P removal from the FTW systems for two of the three species studied, maidencane and bushy bluestem. Higher pH treatments reduced nutrient removal efficacy, but plants were still capable of consistently removing nutrients across all pH treatments. Conversely, ‘Rising Sun’ japanese iris maintained similar remediation efficacies and removal rates across all pH treatments for both N and P, possibly due to the ability to acidify its rhizosphere and modify the pH of the system. Average N and P loads were reduced by 47.3 g·m−3 N (70%) and 16.6 g·m−3 P (56%). ‘Rising Sun’ japanese iris is a promising plant for use in highly variable conditions when the pH of irrigation runoff is outside the typical range (5.5–7.5). Results from model simulations poorly predict the nutrient availability of P and ammonium in effluent, most likely due to the inability to determine plant and biological contributions to the system, such as N-fixing bacteria.

Prevalence of autoimmune hematologic and non-hematologic conditions in large granular lymphocytic leukemia: exploratory analysis of a series of consecutive patients.

Abstract: Large granular lymphocytic (LGL) leukemia is a relatively rare but well-defi ned clonal lymphoproliferative disorder, typically of indolent clinical behavior and associated with certain autoimmune conditions including immune cytopenias. At our institution, we studied a series of consecutive patients with T-LGL leukemia in the outpatient setting and explored the prevalence of autoimmune hematologic and non-hematologic conditions. Th e presence of these conditions in our cohort was compared with their documented prevalence in the general population and was tested for statistical signifi cance using both χ 2 test and Fisher test for a small number of observations (95% confi dence); a p -value 0.05 was considered signifi cant. A total of 22 patients ( n 22) were diagnosed with LGL leukemia at our institution between the years 2004 and 2013. Th e vast majority of patients were originally referred to us for evaluation of asymptomatic peripheral cytopenias. Diagnosis of LGL leukemia was made according to the World Health Organization (WHO) 2008 criteria including the following attributes: persistence of absolute or relative numbers of large granular lymphocytes without a clear etiology; unexplained cytopenias; aberrant T-cell antigen expression by fl ow cytometry; establishment of clonality via T-cell receptor (TCR) gene rearrangement studies; and/or demonstration of bone marrow involvement by LGL cells [1]. Th e clinicolaboratory data, peripheral blood immunophenotyping results, bone marrow morphology and fl ow cytometry, as well as TCR gene rearrangement studies at the time of diagnosis, were retrospectively reviewed. Th e majority of patients in our cohort were men (59%) and the median age was 75 years (range, 48 – 90) at the time of diagnosis. Most patients were asymptomatic at the time of presentation and had at least one peripheral blood abnormality associated with T-LGL leukemia. Leukopenia was present in 73% of cases, with a median leukocyte count of 3.4 10 9 /L (range, 1.7 – 3.9 10 9 /L); neutropenia was identifi ed in 63% of cases, with a median absolute neutrophil count of 1.1 10 9 /L (range, 0.2 – 1.7 10 9 /L).
