چکیده
This is the first study of broad range chemical classes CECs conducted in upper Wisla river catchment including biggest WWTPs this region and surface waters. The list compounds extensive paper provides, for time, better understanding environmental burden from PCPCs Poland. Cumulative contribution hypertension pharmaceuticals, nonsteroidal anti-inflammatory drugs (NSAIDs) lifestyle chemicals was 89% 95% wastewater influent, 75% effluent at both WWTPs. Significant removal efficiencies, exceeding 90%, were found parabens, UV filters, NSAIDs, steroid estrogens, plasticizers, antibacterials/antibiotics, stimulants metabolites chemicals. comparison average mass loads between influent effluent, has shown that 27% 29% all detected removed by less than 50%. An increase concentrations observed 18% 20% Kujawy Plaszow WWTPs, respectively. Negative balances fexofenadine, venlafaxine, o-desmethyltramadol, ketamine temazepam noted within which are a result dissolution persistent contaminants accumulated aggregates and/or back-transformation or de-conjugation into parent compounds. 44 waters located upstream downstream largely dependent on dilution factor WWTP discharge. risk quotation (RQ) values present calculated relation to their potential bioaccumulation. Among with high bioaccumulation, log KOW ? 4.5, diclofenac, atorvastatin triclosan be risk. Many high, moderate even low impact have bioaccumulation should considered as priority same level. Moreover, possible synergistic action still concern.

Removal of selected endocrine disrupting chemicals and personal care products in surface waters and secondary wastewater by ozonation.
This study investigated the removal of parabens, N,N-diethyl-m-toluamide (DEET), and phthalates by ozonation. The second-order rate constants for the reaction between selected compounds with ozone at pH 7 were of (2.2 +/-0.2) X 10(6) to (2.9 +/-0.3) X 10(6) M 1/s for parabens, (2.1+/- 0.3) to (3.9 +/-0.5) M-1/s for phthalates, and (5.2 +/-0.3) M-1/s for DEET. The rate constants for the reaction...

امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
The occurrence of illicit and therapeutic pharmaceuticals in wastewater effluent and surface waters in Nebraska.
The occurrence and estimated concentration of twenty illicit and therapeutic pharmaceuticals and metabolites in surface waters influenced by wastewater treatment plant (WWTP) discharge and in wastewater effluents in Nebraska were determined using Polar Organic Chemical Integrative Samplers (POCIS). Samplers were installed in rivers upstream and downstream of treated WWTP discharge at four sites...
