One of the major issues related to the environment in the 21st century is sustainable development. The innovative economic growth policy has supported relatively successful economic development, but poor environmental conservation efforts, have consequently resulted in serious water quality pollution issues. Hence, assessments of water quality and health are fundamental processes towards conser...

background : among the industrial activities that may cause odor nuisance problems, baking waste one is of the sources of bad odor, and therefore individuals complain from the industry. the aim of this study was to evaluation of pollutants released from poultry rendering plant and also performance of existing refiners in removing these pollutants.   methods : in this study, 66 air samples were ...

A passive sampler inspired from previous devices was developed for the integrative sampling of a broad range of contaminants in the water column. Our primary objective was to improve the performance of the device to provide accurate and averaged pollutant water concentrations. For this purpose, an agarose diffusive gel was used as the boundary layer that drives the analyte uptake rate. Contrary...

Semiconductor heterogeneous photocatalysis, the subject of this review, is a versatile, low-cost and environmentally benign treatment technology for a host of pollutants. These may be of biological, organic and inorganic in origin within water and air. The efficient and successful application of photocatalysis demands that the pollutant, the catalyst and source of illumination are in close prox...

Water quality models can be effective tools to simulate and predict pollutant transport in coastal water environment, which can contribute to saving the cost of labours and materials for a large number of industrial development in the coastal region. Therefore, water quality models become an important tool to identify water pollution and the final fate and behaviours of pollutants in coastal en...

The water quality of rivers, lakes or reservoirs changes in both short and long term. For a given catchment with known pollution sources, different combinations of hydrologic and pollutants discharges scenarios may result in different impacts in the water quality. The objectives of the present work were to analyze the methodologies currently used for assessment of pollution impacts in lakes and...

-Water pollution has become one of the most serious problems of today’s civilization. In the last few years considerable amount of research has been done on the potential of aquatic macrophytes for pollutant removal or even as bio-indicators for heavy metals in aquatic ecosystems. Water hyacinth is one of the aquatic plant species successfully used for wastewater treatment. It is very efficient...

Composite heteronanostructures hold promise for high photocatalytic efficiency for water splitting and the degradation of organic pollutants. However, their photocatalytic activity under broadband excitation has been challenging, until now.

The efficient removal of trace carcinogenic organic pollutants, such as polycyclic aromatic hydrocarbons (PAHs) and ionic dyes, from water is an important technical challenge. We report a highly effective recyclable multifunctional azobenzene (AZ)-based silica-supported polymeric adsorbent which can simultaneously remove both PAHs and anionic dyes from water to below parts per billion (ppb) lev...

The demand for fresh water is increasing with the growth in world population, and obtaining an adequate supply of clean water has likely been the challenge for many countries. To solve this problem, using water from unconventional sources is the best method from economic point of view. To make wastewater reuse safety, all the pollutants including biodegradable organic matter [1,2], pathogens [3...
