Water that has been used by people and is disposed into a receiving water body with altered physical and/or chemical parameters is defined as wastewater. If only the physical parameters of the water were changed, e.g., resulting in an elevated temperature after use as a coolant, treatment before final disposal into a surface water may require only cooling close to its initial temperature. If th...

Phytoplankton are microscopic plants that live in the ocean, sea or lake. Through photosynthesis, phytoplankton are responsible for much of the oxygen present in the Earth’s atmosphere. They convert inorganic materials into new organic compounds by the process of photosynthesis [14]. Hence the stocks of these tiny planktonic algae play a significant role for marine reserves and fishery manageme...

The aims of this study was to determine the effect of organic and inorganic Zn and Cu supplements on performance, footpad dermatitis (FPD), carcass characteristics and blood profile in broiler chickens. A total of 336 one-day-old Ross 308 broiler chicks were distributed into 24 floor pen and reared for 42 days. A basal mineral premix (without Zn and Cu) was supplemented with organic or inorgani...

Intensification of industrial activity, environment stress contributes to the significant rise heavy metal pollution in water resources. Pollution due malignant metals such as lead, chromium, arsenic etc., has been tremendously focused on communal health. Lead pollution-potable finds great threat by different sources like plating units, lead pipes Newspaper is a cellulosic materials, containing...

Mismanagement, pollution and excessive use have depleted the world’s water resources, producing a shortage that in some territories is extreme. In this context, need for potable prompts development of new more efficient wastewater treatment systems to overcome shortages by recovering reusing contaminated water. Among methods, membrane technology considered one most promising. Besides, photocata...

This study examined spatial relationships between rocky shore polychaete assemblages and environmental variables over broad geographical scales, using a database compiled within the Census of Marine Life NaGISA (Natural Geography In Shore Areas) research program. The database consisted of abundance measures of polychaetes classified at the genus and family levels for 74 and 93 sites, respective...

A novel electrochemical device was used to recover copper metal from an inorganic chemicals process effluent. In a sidestream pilot-plant demonstration, the copper content was continuously reduced from an average of 20 mg/l to less than 2 mg/l. The basic concepts, laboratory testing, and pilot-plant demonstration are described. General Future water-pollution regulations may require effluent con...

With rapid industrial development, problems related to pollution are becoming severe Water pollution is one of the most serious problems because inorganic and organic wastes are discharged to the aquatic environment either in water soluble or insoluble forms. Heavy metal ions have lethal effects on all forms of life and these enter the food chain through the disposal of wastes in water channels...

China implemented strict emission control measures in Beijing and surrounding regions to ensure good air quality during the 2014 Asia-Pacific Economic Cooperation (APEC) summit. We conducted synchronous aerosol particle measurements with two aerosol mass spectrometers at different heights on a meteorological tower in urban Beijing to investigate the variations in particulate composition, source...

The chemical composition of airborne particulate matter (PM) was studied at a coastal region near De Haan, Belgium, during a winter-spring and a summer campaign in 2006. The major ionic components of size-segregated PM, i.e. NH(4)(+), Na(+), K(+), Mg(2+), Ca(2+), Cl(-), NO(3)(-), and SO(4)(2-), and related gaseous pollutants (SO(2), NO(2), NH(3), HNO(2), and HNO(3)) were monitored on a daily ba...
