In previous studies we detected lower species richness and lower Hg sensitivity of the bacteria present in egested guts of Porcellio scaber (Crustacea, Isopoda) from chronically Hg polluted than from unpolluted environment. Basis for such results were further investigated by sequencing of 16S rRNA genes of mercury-resistant (Hgr) isolates and clone libraries. We observed up to 385 times higher ...
Two of the largest crude oil-polluted areas in the world are the semi-enclosed Mediterranean and Red Seas, but the effect of chronic pollution remains incompletely understood on a large scale. We compared the influence of environmental and geographical constraints and anthropogenic forces (hydrocarbon input) on bacterial communities in eight geographically separated oil-polluted sites along the...
Accumulation of nickel, lead, copper and zinc in the liver of a freshwater fish, Tor putitora has been studied from polluted waters of River Kabul at two different sites and compared with those from pristine Warsak Dam reservoir upstream of polluted part of the River Kabul. The liver of fish from polluted site showed higher concentration of zinc (1300% and 3100%), nickel (21.1% and 25.5%), lead...
A river carries pollutants to people living along it if it is polluted. To make the water in the river clean, some costs are incurred. This poses a question of how to split the costs of cleaning the whole river among the agents located along it. To answer this question, we resort to the two main advocated doctrines in international disputes: the theory of Absolute Territorial Sovereignty (ATS) ...
Even after 7 years of the nuclear accident that occurred in 2011 at Fukushima Dai-ichi power plant (F1NPP), high levels 137Cs have been detected ambient aerosols from some polluted areas Fukushima. Higher radionuclides were often observed atmosphere during and rain events. We presume biological processes such as fungal activity associated with higher relative humidity may be involved a possible...
In this data article, by using inductively coupled plasma optical spectrometry (ICP-OES), we aimed to (1) determine the concentration levels of As, Ag, Sr, Sn, Sb, and Mo in the sediments and the shells of Trachycardium lacunosum simultaneously in two separated areas (unpolluted and polluted areas) (2) comparison between the metal contents of sediments in the unpolluted and polluted areas as we...
The main reactive air pollutants are SO2, H2S, sulphate compounds, NH3, NO, N02 and other oxidants and hydrocarbons. On the basis of a survey on the production and mean distribution of these compounds in pure and polluted atmospheres several chemical reactions are considered. The meteorological parameters, sun radiation, water vapour and the liquid water content of clouds modify these chemical ...
The haematological effects following ingestion of shellfish exposed to crude oil polluted water or the pollutant perse were investigated in albino Wistar rats. Feeding of four groups of rats for 28 days duration with two reference casein or shellfish protein control diets (Group A and B), and two test diets (Group C and D) supplemented at varying levels with shellfish which had been previously ...
Subrabharathimanian is one of the modern writers who deeply concerned about society and environment. In most his works he has written Noyyal river how it been polluted by dye waste garbage from Banyan companies. Most novel pollution atmosphere due to fumes factories, global warming, people being mentally affected noise vehicles diseases because this. He said women workersin Samayalarai Kalaiyan...
Despite the trend of a transition to “clean” energy, coal industry still plays significant role in global economy. The constant need for raw materials and energy production leads an environmental crisis—an increase content greenhouse gases atmosphere, especially mining regions. purpose this study was analyze impact carbon footprint on environment ways reduce negative enterprises ecology. To cho...
