We analyze the different regional and generational contributions to increases of C02 concentrations resulting from fossil-fuel use since the onset of the industrial revolution. Equitable future per capita emission allowances under a range of concentration stabilization scenarios (additional 140, 280, and 420 ppm over pre-industrial levels) by the year 2100 are outlined. The intraand inter-gener...
Background: Hydroxymethylfurfural (HMF) is a common Maillard reaction product directly formed from dehydration of sugars under acidic conditions during heating and storage in carbohydrate rich foods. The aim of the present study was to detect and quantify the amount of HMF in date syrup by HPLC method. In addition, the amount of HMF in date syrup produced by traditional and industrial methods w...
Industrial wastewater treatment is of high priority due to the presence an extraordinary concentration dangerous pollutants. Similar urban plants, there are plenty options while designing industrial ones which need various analyses and researches choose correctly.
Background & Objectives: Determining the impacts of air pollution in cities is facing two major challenges first, the limited data on the health effects of pollutants, and secondly, the lack of information on exposure to air pollutants and their concentration. This is an applied-observational carried out to determine the concentration, seasonal changes, and to estimate the health impacts attrib...
Background: PCE is a chlorinated aliphatic hydrocarbon which has been used in some industries. Industrial wastewaters polluted with PCE must be treated because of its possible carcinogenic effects. The aim of this study was to determine the PCE biodegradation potential in high concentration using Anaerobic Migrating Blanket Reactor (AMBR) that thus far has not been used for biodegradation of th...
Background and purpose: Phenol whose carcinogenic property has been evidenced is one the organic compounds found in industrial wastewater. Therefore, this effluent must be treated before it is discharged to the environment. The aim of this study was to investigate whether dried azolla can absorb phenol from aqueous solution. Materials and methods: First, the collected azolla was washed by dis...
As an industrial economic organization with specific characteristics, industrial cluster is emerging with strong dynamism in global competition and driving the development of regional economy. However, industrial cluster can bring some negative impact on regional economy development. This paper tries to illustrate the reasons for the stagnation and degradation of resource-based regional industr...
The process of pollutant adsorption from industrial wastewaters is a multivariate problem. This process is affected by many factors including the contact time (T), pH, adsorbent weight (m), and solution concentration (ppm). The main target of this work is to model and evaluate the process of pollutant adsorption from industrial wastewaters using the non-linear multivariate regression and intell...
