Background and Objective: Due to the increasing trend of municipal solid waste (MSW) production, if a suitable management system is not applied, it will lead to environmental pollution and endanger human health. The aim of this study was to compare different scenarios of waste management in Chalous city with life cycle assessment (LCA) approach and to select the most efficient method in terms o...
This work contributes to the monitoring of heavy metal pollution Agricultural soils, Katsina State Nigeria, using Atomic Absorption Spectrophotometry. The contamination soil samples were analyzed based on Geoaccumulation index (Igeo), enrichment factor (EF), (CF), load (PLI) and potential ecological risk (PERI). health risks evaluated metals estimated Hazard Quotient (HQ) Index (HI)) evaluate p...
2. OVERVIEW OF GIR SYSTEM 2.1 Pre-process The GIR system requires a text index and a geographic index. As the text index, those created for existing full-text search can be used. The geographic index is made by using NE recognizer, which locates place name expressions in texts as geo-references and geo-coder, which assigns coordinates to each geo-reference. The geographic index of our method al...
Water quality assessment at the watershed scale requires not only an investigation of water pollution and the recognition of main pollution factors, but also the identification of polluted risky regions resulted in polluted surrounding river sections. To realize this objective, we collected water samplings from 67 sampling sites in the Honghe River watershed of China with Grid GIS method to ana...
Heavy metal pollution may pose a significant threat to aquatic ecosystems. To assess heavy pollution, sediment samples were collected from Changwang and Wuyuan Rivers between June December 2019. An inductively coupled plasma mass spectrometer was used analyze the concentrations of As, Cd, Co, Cr, Cu, Mn, Ni, Pb, Zn. The results revealed that River had significantly high Cr (240.70 mg kg−1), Co ...
background: in recent decades, studies on type 2 diabetes (t2d), have adopted a new approach to the field of a more complete collection of variables related to the lifestyles and diet of people. diet is an important factor in increasing the rate of t2d among individuals. considering the consumption of a high-carbohydrate diet, little attention has been paid to the type of carbohydrates consumed...
Due to the lack of water quality of resourses in country, exact review of available water resources quality, especially in terms of heavy elements (heavy metals) has a particular importance. Due to industrial towns 1 and 2 of Yasuj city and also Yasuj wastewater treatment, surveying environmental harmful effects of heavy metals on this river is very important. To investigate the changes of heav...
the development of a surface water evaluation index is a critical factor in the assessment, restoration and protection of stream water quality. quantifying water pollution in specific grade using dominant parameters is important, as this can explain the current state of water pollution with accuracy. as a result, an integrated multi-parameter water quality index has been developed. it is based ...
in this study, the concentrations of heavy metals (ca, zn, cu, fe, mn, ni) in thesediment of shavoor river in khuzestan province in iran has been investigated. after the library studies and field studies, six samples of water and sediment were taken from the river in order to evaluate heavy metal pollution in sediments. to determine the geochemical phases of metals in sediment samples the 5-ste...
Background and Objective: Landfills as municipal solid waste are considered as the source of pollution. The present study aimed to assess the ecological risk of heavy metals in Tehran landfill soil and the adjacent residential area. Materials and Methods: Having consulted with the specialists and considered the waste processing facilities, 12 sampling points were selected and sampled in four s...
