Monitoring early-season agricultural drought using temporal Sentinel-1 SAR-based combined drought index
Environmental Monitoring and Assessment - - 2023
Dilip, T., Kumari, Mamta, Murthy, C. S., Neelima, T. L., Chakraborty, Abhishek, Devi, M. Uma
Early-season agricultural drought is frequent over South Asian region due to delayed or deficient monsoon rainfall. These drought events often cause delay in sowing and can even result in crop failure. The present study focuses on monitoring early-season agricultural drought in a semi-arid region of India over 5-year period (2016–2020). It utilizes hydro-climatic and biophysical variables to devel...... hiện toàn bộ
Influence of Aluminium on the Restoration Potential of a Terrestrial Vascular Plant, Portulaca Oleracea L. as a Biomonitoring Tool of Fresh Water Aquatic Environments
Environmental Monitoring and Assessment - Tập 78 Số 1 - Trang 19-29 - 2002
Anandi, S., Thangavel, P., Subburam, V.
In the present study, the influence of aluminium on the regeneration potential of leaf and stem-cuttings of Portulaca oleracea was studied in order to identify a terrestrial plant species as an alternate biomonitoring toolof fresh water environment. The leaves and stem cuttings of theterrestrial plant, P. oleracea grew well in the distilled water producing adventitious and lateral roots. The alumi...... hiện toàn bộ
Monitoring the results of Canada/U.S.A acid rain control programs: some lake responses
Environmental Monitoring and Assessment - Tập 88 Số 1 - Trang 3-19 - 2003
Jeffries, D.S., Brydges, T.G., Dillon, P.J., Keller, W.
Aquatic acidification by deposition of airborne pollutants emerged as an environmental issue in southeastern Canada during the 1970s. Drawing information from the extensive research and monitoring programs, a sequence of issue assessments demonstrated the necessity of reducing the anthropogenic emissions of acidifying pollutants, particularly sulphur dioxide (SO2). The 1991 Canada-U.S. Air Quality...... hiện toàn bộ
Incidence of Stress in Benthic Communities along the U.S. Atlantic and Gulf of Mexico Coasts within Different Ranges of Sediment Contamination from Chemical Mixtures
Environmental Monitoring and Assessment - Tập 81 Số 1 - Trang 149-161 - 2003
Hyland, Jeffrey L., Balthis, W. Leonard, Engle, Virginia D., Long, Edward R., Paul, John F., Summers, J. Kevin, Van Dolah, Robert F.
Synoptic data on concentrations of sediment-associated chemical contaminants and benthic macroinfaunal community structure were collected from 1,389 stations in estuaries along the U.S. Atlantic and Gulf of Mexico coasts as part of the nationwide Environmental Monitoring and Assessment Program (EMAP). These data were used to develop an empirical framework for evaluating risks of benthic community-...... hiện toàn bộ
Spatial Patterns of Nitrate, Chloride, Sulfate, and Fluoride Concentrations in the Woodbine Aquifer of North-Central Texas
Environmental Monitoring and Assessment - Tập 82 Số 3 - Trang 311-320 - 2003
Hudak, Paul F., Sanmanee, Sirichai
A geographic information system was used to map and analyze nitrate, chloride, sulfate, and fluoride concentrations in 110 wells tapping the Woodbine Aquifer. The study area, covering ninecounties in north-central Texas, includes large percentages of both urban and agricultural land uses. Land use maps were compared with solute concentration data, and statistics were applied to detect associations...... hiện toàn bộ
Mapping of high-resolution daily particulate matter (PM2.5) concentration at the city level through a machine learning-based downscaling approach
Environmental Monitoring and Assessment - Tập 197 Số 1

Assessment of species and antimicrobial resistance among Enterobacteriaceae isolated from mallard duck faeces
Environmental Monitoring and Assessment - - 2015
Murugaiyan, Jayaseelan, Krueger, Karolin, Roesler, Uwe, Weinreich, Joerg, Schierack, Peter
Mallard ducks have demonstrated to be a likely reservoir for zoonotic E. coli strains; thus, it is possible that these ducks could also act as a reservoir for other Enterobacteriaceae members. The present study was initiated to evaluate the species distribution of Enterobacteriaceae other than E. coli in 175 fresh faecal samples collected from a population of mallard ducks. Sixty-four samples disp...... hiện toàn bộ
Influence of coal-based thermal power plants on the spatial–temporal variability of tropospheric NO 2 column over India
Environmental Monitoring and Assessment - - 2012
Prasad, Anup K., Singh, Ramesh P., Kafatos, Menas
The oxides of nitrogen—NO x (NO and NO2)—are an important constituent of the troposphere. The availability of relatively higher spatial (0.25° grid) and temporal (daily) resolution data from ozone monitoring instrument (OMI) onboard Aura helps us to better differentiate between the point sources such as thermal power plants from large cities and rural areas compared to previous sensors. The annual...... hiện toàn bộ
Bioassessment of Streams using Macroinvertebrates: Are the Chironomidae Necessary?
Environmental Monitoring and Assessment - Tập 71 Số 2 - Trang 177-185 - 2001
Rabeni, Charles F., Wang, Ning
We compared the sensitivity of commonly usedbioassessment metrics to detect organic impairment ofstreams using data sets that varied only in the inclusion orexclusion of Chironomidae identified to genus. We evaluatedsituations in two contrasting ecoregions of Missouri, U.S.A.,the Ozark ecoregion and the Prairie ecoregion whereChironomidae comprise an average of 32 and 42%,respectively, of the tota...... hiện toàn bộ
Methane Emissions of Differently Fed Dairy Cows and Corresponding Methane and Nitrogen Emissions from their Manure during Storage
Environmental Monitoring and Assessment - Tập 79 Số 2 - Trang 129-150 - 2002
Külling, D. R., Dohme, Frigga, Menzi, H., Sutter, F., Lischer, P., Kreuzer, M.
This study investigated the effects of supplementing 40 g lauric acid (C12) kg-1 dry matter (DM) in feed on methane emissions from early-lactating dairy cows and the associated effects on methane, nitrous oxide and ammonia release from the manure during storage. Stearic acid (C18), a fatty acid without assumed methane-suppressing potential in the digestive tract of ruminants, was added at 40 g kg-...... hiện toàn bộ
