Phenol and it derivatives are considered as one of the priority pollutants in waste water, because they are harmful to organisms even at very low concentrations. The control as well as removal of these organic compounds has become an important issue due to stringent measures introduced by various countries to enforce regulations concerning wastes originating from various industries. Hence, wast...

During the past several years, waste produced by the electroplating industry has attracted attention due to the level of pollutants found in the waste stream, the difficulty associated with treatment, and the cost of waste disposal. EPA has enacted regulations to control the discharge from plating facilities and estimates that 140 million lb of metal pollutants will be prevented from being disc...

Abstract The exchangeable cations and anionic pollutants of Okpoka-Woji River serving as a sink for effluents of industries located in the vicinity within the Trans-Amadi industrial area were carried out. Sediment samples were collected from six sampling stations located along the channel for the assessment of exchangeable cations namely calcium, magnesium, potassium, and sodium and nitrite, ni...

ublicly owned treatment works (POTWs) are beginning the process of identifying air emissions from their wastewater treatment and collection facilities. Many of these facilities will be required by local and state regulatory agencies to reduce emissions to meet air quality or health risks standards. Emissions include odors and toxic, reactive, volatile and criteria pollutants. A wide range of re...

Measurements of gaseous SO2, NO, NO2, H2S, O3, NH3 and VOCs, in Kuwait city using IVL passive sampler technology, were obtained on monthly basis during the period from March 2011 to February 2012 at 10 locations. The results of this study reveal that those compounds had low concentrations compared to Kuwait Environment Public Authority standards for residential areas. It is found that nitrogen ...

Mercury (Hg) is one of the most important heavy metals in estuarine and coastal sediments. This is due to its toxic effect on marine invertebrates and tendency for the methyl-Hg to bio-accumulate up trophic levels, where it can enter humans via the has a highly industrialised and urbanised drainage basin of approximately 5000 km 2. Elevated Hg concentrations (>2 mg/kg) in sediments from the Mer...
