the membrane separation technology by relying on microfiltration ultrafiltration, and reverse osmosis methods are becoming more important among consulting engineers, designers of environmental pollution control system, and industrial factories. the advantages of this technology together with its emphasis on recycling the fluid to the system and reusing the membranes have caused the membranes to...
Tillandsia usneoides L. is an epiphytic bromeliad plant able to absorb water and nutrients directly from the air. For this reason this species was selected to carry out a monitoring study of air pollution in the metropolitan region of São Paulo, Brazil. Five consecutive transplantation experiments (8 weeks each) were performed in 10 sites of the city, submitted to different sources of air pollu...
Environmental pollution is the major problem associated with rapid industrialization, urbanization and rise in living standards of people. Efforts has to be made for controlling pollution arising out of the disposal of wastes by conversion of these unwanted wastes into utilizable raw materials for various beneficial uses. The problems relating to disposal of industrial solid wastes are associat...
In recent years, because of China's rapid economic growth, the contradiction between energy consumption, environmental pollution and economic development has become acute increasingly. Energy-saving and ejection-decreasing has become an important strategy target in China's "11th Five-Year Plan". The research on the industrial structure optimization of China, should be given full consideration t...
In this study, the Scots pine (Pinus sylvestris L.) C needles (i.e. the current-year-needles) were used as bioindicators in determining the aerial distribution pattern of sulphur emissions around industrial point sources at Kemi, Northern Finland. The average sulphur concentration in the C needles was 897 mg/kg (d.w.), with a standard deviation of 118 mg/kg (d.w.) and range 740 – 1350 mg/kg (d....
Environmental pollution poses a great health hazard to human beings, animals and plants. Pollution has also adverse effects on the land, water and its living and nonliving components. Industrial effluents, containing organic and inorganic compounds have strong influence on the development of growth of crop plants. When the concentration of the pollutants in the effluents are low, the agricultur...
It is widely accepted that excessive urbanization, concluded into intense industrial activities near residential districts, with unpleasant effects to the citizens health. Furthermore, shipbuilding and ship repairing consists one of the polluting industrial activities in the country – and more precisely concerning the widely capital region – in spite of the recession that has come to the last y...
Bor and the surroundings (Eastern Serbia) have a poor air quality, due to emissions from the miningmetallurgical complex for copper production. Considering the processing and smelting of sulphide ores, one of the dominant air pollutant is SO2, which causes acidification of waters and soil, affecting vegetation. Biomonitoring of air pollution was conducted in order to examine the effect of the i...
Effluent discharges from municipal, industrial, and agricultural activities constitute major sources of pollution on land and water bodies. During the 1990s, large-scale application of Constructed Wetlands (CWs) as a remediation option drew much attention globally from the public and green groups alike. The most common application of CWs is for flow management in river system and little is docu...
The aim of the study was to assess trace metal air pollution in the Beskidy Mountains, the Outer Western Carpathians, Poland, with a widely used bioaccumulating organism, a lichen, Hypogymnia physodes. Lichens were collected at five stands (mountains) in parallel transect and analyzed for cadmium (Cd), copper (Cu), nickel (Ni), lead (Pb) and zinc (Zn) content. Concentrations of Cd, Pb and Zn in...
