Effects of using Tamarindus indica Seeds as a natural coagulant aid in landfill leachate treatment
Solid Waste Management
Uncontrolled landfill leachate generation portends danger to the environment and aquatic ecosystem, especially without prior treatment before discharge. The application of Al-based coagulants, such as polyaluminum chloride (PACl), has the potential of introducing Al residuals into water bodies...
Kinetic, isotherm and thermodynamic investigations of nitrite (NO2–) removal from water by anion exchange resins
Water and Wastewater Treatment
This study presents the evaluation of a strong base (Purolite A200) and weak base (Purolite PFA847) polymeric anion exchange resins for nitrite removal. The different parameters on the removal of NO2– were investigated in batch sorption mode. Common isotherm models; Langmuir and Freundlich, were...
A comprehensive evaluation of the level of noise pollution in hospitals of Kermanshah University of Medical Sciences
Pollution Control Technology
Noise pollution higher than the standard values intensifies the patients' disease and also has negative effects on hospital staff. This study aimed to determine the level of noise pollution in the Kermanshah hospitals and also to compare obtained data with national and international standards...
Use of Multivariate Statistical Analysis for the Assessment of Groundwater Chemical Variations in Wadi Bani Malik Area, Saudi Arabia
Water Quality
Multivariate statistical analysis including cluster analysis, factor analysis and correlation coefficient was applied to the groundwater samples to understand the groundwater condition in Wadi Bani Malik area. Water samples collected from the study area were analysed for physical parameters, major...
Temporal variation of mercury in Turkish Black Sea waters and associated risk assessment
Environmental Sciences
Presence of metals even at trace levels in natural waters pose sever health risks. Heavy metals are introduced to coastal and marine environments through a variety of sources and activities including sewage and industrial effluents where Black Sea is not different. However, metals behave differently...
Influence of city municipal waste disposal on groundwater quality and assessment of groundwater suitability in agriculture
Environmental Sciences
This study focuses on the impact of the disposal of Tirunelveli city municipal waste in the quality of groundwater in Ramayanpatti village where the waste is disposed; the study also assesses the quality of the groundwater suitability in irrigation in the disposed region. Tirunelveli city generates...
Public concerns and behaviors towards solid waste minimization using composting in Kampar district, Malaysia
Solid Waste Management
Municipal solid waste generation in Malaysia has increase significantly. Organic materials continue to be the major portion of solid waste generated in Kampar, Malaysia. As a result of increasing rate of waste generation and population growth, land area will become more demanding causing the...
Assessment of PM1 number concentration with respect to traffic flow and thermal environment in a residential underground garage
Air Quality
Particles with aerodynamic diameters 1 μm (PM1) damage human health more severely than do coarse particles. In this study, PM1 number concentration, traffic flow, temperature and relative humidity in both a residential underground garage and at the entrance/exit, wind velocity at the entrance/exit...
Investigation of climate change impacts on tourism climate comfort in Iran
General
In this study, Mieczkowski's Tourism Climate Index (TCI) was used for Iran to investigate the climate change impacts on outdoor human comfort. The long-term data covering a network of 153 stations were used to compute TCI under baseline conditions (1981–2015) and a climate change scenario (HadCM3...
Forecasting PM10 levels using ANN and MLR: A case study for Sakarya City
Air Quality
In this study, potential of neural network to estimate daily mean PM10 concentration levels in Sakarya city, Turkey as a case study was examined to achieve improved prediction ability. The level and distribution of air pollutants in a particular region is associated with changes in meteorological...
