Mining operations and mineral-related industries are closely and directly related with the environment. The negative impacts of mining industry on the environment, known as environmental risks, must be controlled and managed in a way to minimize harmful and destructive effects. Environmental risk assessment studies are a suitable step to identify, analyze and rank the risk factors. In this stud...
in this paper, two formulas were chosen among those that estimate the suspendedsediment discharge in rivers. these two formulas were lane and kalinske and bagnold. forstudying and knowing the correlation between input parameters and calculated suspendedsediment discharge (cssd), the spss17 software was used. input parameters in these twoformulas were as: water velocity, water discharge, suspend...
abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
Reclamation and reuse programs are an indispensable part of integrated water resource management, particularly in arid and semi arid regions. Yet, the feasibility of sustainable application not only is relied on design, operation and maintenance of wastewater treatment plants, but also could be influenced by the economical and environmental aspects of reuse demands. This study is aimed to illus...
Introduction: Nowadays rapid and widespread urbanism put people health in danger and led to health in global and general conferences and actualization methods like healthy city project in many cities. The aim of this study is evaluation of healthy city indicators (health, environmental and social-economical) in Kerman city in 2012. Method: This study is a mix method (qualit...
Governmental environmental protection is often implemented by specifying a standard value of pollution, measured or actual, not to be exceeded. We consider the standard for ozone in the United States, interpreting it using a hypothesis testing framework, and show (in a simplified setting) how a statistician could implement this standard. This implementation is contrasted to the implementation b...
Background and Aim: Sewage of non-metallic and mineral industrials such as tile and ceramic contain a large amount of heavy metals (e.g. Zn, Cr, Cd, Pb) and minerals which can cause problems such as contaminating underground water and polluting the environment. Thus, the present study was done to evaluate heavy metals concentration in the effluent and sludge of the tile factory in Birjand. ...
behaviour of the dilution characteristics of the coastal waters off tuticorin is presented in thebackground of setting up of a desalination plant. simulations of dispersion and spreading of the proposeddischarges has been carried out. scenarios of dilutions were assessed based on the results of a 2d model using the advection-dispersion theory. it is observed that under prevailing currents in th...
OBJECTIVE To evaluate the environmental quality of Guiyu, Guangdong impacted by the electronic waste recycling industry. METHODS The surface water, ground water and sediment samples taken separately from two sites that recycle E-wastes and other rubbish relevant to the E-waste recycling, and an agricultural area, were analyzed, and the data were used to evaluate the impact of E-waste recyclin...
