UNLABELLED BACKGROUND Taihu Lake is a typical plain eutrophic shallow lake. With rapidly economic development of the lake area, the petroleum products and oil wastewater produced in various processes have been inevitably discharged into Taihu Lake. As the major fresh water resource in the economically developed region of Yangtze River Delta, the water quality and environmental condition of T...

Polychaetes are usually the most abundant taxon in benthic communities and have been most often utilized as indicator species of environmental conditions. This review finds that, while the use of indicator species for a particular pollutant is not simple, polychaetes can provide a useful means of assessing the effects of poor environmental conditions. Polychaetes may be used as sensitive monito...

air pollutants are reported to increase the specific ige response to allergens. clinical tests and immonoblotting were performed with pollen grains of spartium junceum. to identify allergens and to determine the effect of air pollutants on the allergenicity of the pollen extracts, the pollen extracts were injected intraperitoneally and intracutaneously to guinea pigs. injection of the pollen ex...

nowadays, we live in a world which quality, speed, accuracy and cost are the most important parameters in parts' design and manufacturing. due to the complexity of part manufacturing, traditional and nontraditional manufacturing techniques are used. aerodynamic tests usually requires one or several models for testing in wind tunnels and these models typically have particular complexities in whi...

aim and background: smoking and drugs are considered are among the most common causes of early mortality in developing and developed countries. health professionals believe that university period has special characteristics and is of high importance in prevention of smoking among young adults. in this study, we examined with the relations between smoking and psychological and demographic variab...

The prevalence of environmental diseases is increasing worldwide and these diseases are an onerous burden both to the individual and to the public health. Urban air pollution is a grave problem in majority of metropolises, which contain high levels of traffic congestion generating great amounts of genotoxic substances. The contribution of such environmental exposure to increase prevalence of ma...

On the basis of the reported air quality index (API) and air pollutant monitoring data provided by the Guangzhou Environment Monitoring Stations over the last twenty-five years, the characteristics of air quality, prominent pollutants, and variation of the average annual concentrations of SO2, NO2, total suspended particulate (TSP), fine particulates (PM10), CO and dustfall in Guangzhou City we...

There is a demonstrable association between exposure to air pollutants and deaths due to cardiovascular diseases. The objective of this study was to estimate the effects of exposure to sulfur dioxide on mortality due to circulatory diseases in individuals 50 years of age or older residing in São José dos Campos, SP. This was a time-series ecological study for the years 2003 to 2007 using inform...

Benthic amphipod, Grandidierella japonica widely inhabits the Korean coastal waters and is developed as a standard test species for sediment toxicity tests. We exposed G. japonica to various pollutants including 4 kinds of inorganic metals (Ag, Cd, Cu and Hg), tributyltin [TBT], ammonia and 7 polycyclic aromatic hydrocarbon (PAH) compounds (acenaphthene, chrysene, fluoranthene, fluorene, naphth...

The present study investigated the influence of packing material characteristics on the electricity generation performance, treatment efficiency and degradation mechanism of petroleum pollutants over microbial fuel cells (MFCs) using petroleum refinery wastewater (PRW) as fuel. The granule graphite (GG) and granule-activated carbon (GAC) were used to MFCs as packing materials, respectively. GG-...
