Landfill leachate data compiled from 220 different landfills from 46 countries in Europe, Middle East, Asia, Africa, and America were analysed by multivariate statistical approach for the assessment of main properties as well as variation of leachate characteristics with respect to landfill age, climate, and development status. Results showed that inorganic content of leachate has the highest correlations with each other as well as accounting for the majority of variation in leachate. Changes in leachate composition were observed in statistically significant manner with respect to climate, landfill age, and development status only for some parameters including pH, BOD, COD, and BOD/COD ratio. On the other hand, most of the parameters particularly inorganics did not show any statistically important difference between impact groups. Change in leachate quality with time was found significant only in relatively low precipitation climates. Landfill age effect was observed on the organic content of leachate while most of the inorganics were not found statistically different with time. On the contrary, in high precipitation climates, organic content and biodegradability were found low without any time effect, whereas inorganic content was found fluctuating in high quantities. In that respect, leachate age definition in current literature as young, medium, and old needs to be re-evaluated by taking into consideration the climate impact with particular attention to precipitation rates. Comprehensive leachate database and results of statistical analyses suggest that leachate management methods should be evaluated differently for landfills in high and low rainfall climates as well as in developed and developing countries.


Comprehensive analysis and modeling of landfill leachate

© 2022 Elsevier LtdLandfill leachate data compiled from 220 different landfills from 46 countries in Europe, Middle East, Asia, Africa, and America was analysed by multivariate statistical approaches. Data pre-treatment procedure such as handling of outliers, completion of missing data, and standardization of data was applied to prepare the raw data matrix for the complex statistical analyses including cluster and principal component analyses (PCA). Regression modeling was conducted to estimate leachate par...
Comparison of Productivity Plankton Types and Carbon Export Mechanisms in two Different Regimes of Subtropical North Atlantic a Modeling Study
Salihoğlu, Barış (2016-02-15)
Improved structure and mechanisms of carbon export and sequestration within marine ecosystem models is vital to better understand and predict changes in the global carbon cycle. We have implemented a 1D lower trophic ecosystem model at long-term time-series stations (BATS and ESTOC) in the North Atlantic for the years 1996-2000. We have investigated the dynamics of the productivity and carbon export, and mechanisms regulating them. Our simulations agree with the previous observations that show similar produ...
Comparison of satellite-derived LAI and precipitation anomalies over Brazil with a thermal infrared-based Evaporative Stress Index for 2003-2013
Anderson, Martha C.; Zolin, Cornelio A.; Hain, Christopher R.; Semmens, Kathryn; Yılmaz, Mustafa Tuğrul; Gao, Feng (2015-07-01)
Shortwave vegetation index (VI) and leaf area index (LAI) remote sensing products yield inconsistent depictions of biophysical response to drought and pluvial events that have occurred in Brazil over the past decade. Conflicting reports of severity of drought impacts on vegetation health and functioning have been attributed to cloud and aerosol contamination of shortwave reflectance composites, particularly over the rainforested regions of the Amazon basin which are subject to prolonged periods of cloud cov...
Analysis of the best available techniques for wastewaters from a denim manufacturing textile mill
YÜKSELER, hande; UZAL, NİĞMET; ŞAHİNKAYA, ERKAN; KİTİŞ, MEHMET; Dilek, Filiz Bengü; Yetiş, Ülkü (2017-12-01)
The present study was undertaken as the first plant scale application and evaluation of Best Available Techniques (BAT) within the context of the Integrated Pollution Prevention and Control/Industrial Emissions Directive to a textile mill in Turkey. A "best practice example" was developed for the textile sector; and within this context, BAT requirements for one of the World's leading denim manufacturing textile mills were determined. In order to achieve a sustainable wastewater management; firstly, a detail...
Assessment of trace metal pollution in the coastal sediments of Fethiye-Go spacing diaeresis cek Bay (SW Turkey) and evaluation of pollution sources
Gulsen-Rothmund, Halil Ibrahim; ARSLAN, ŞEBNEM; Kurtulus, Bedri; Tunca, Evren; Avşar, Ulaş; Avsar, Ozgur (2023-01-01)
This research evaluated the trace metal pollution and the pollution sources in the coastal sediments of Fethiye-Go center dot cek Bay by using the spatial distribution maps, correlation and statistical analysis, which were acquired from 69 sampling points. Spatial distribution maps for eleven elements (namely Al, As, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb, Ti, V, and Zn) revealed that there is an enrichment of the studied elements, especially near Fethiye harbor. Moreover, the contamination evaluation carried out b...
