Road dust (RD) is one of the most important sources particles in atmosphere, especially industrial areas and cities. In this special issue, we collected 16 original articles that describe field, experimental, modeling studies related to RD its various size fractions as a key issue understanding relationships between several urban environments identification pollution sources. Articles focus pri...

The article is the investigation of heavy metals pollution on surface waterin Ikoli River and Epie creek in Yenagoa, metropolis, Bayelsa State. Pb,Cd, Ni, Cr, Fe, Zn was determined evaluated using GeographicalInformation System. Zinc concentration below permissible limitof 3 mg/L all locations sampled. Iron 77.78% limit ofWHO 2011 0.3 while other examined Riverand are highly polluted. index for...

The study of aerosol exposure, dosimetry measurements and related quantitation of health effects are important to the understanding of the consequences of air pollution, and are discussed widely in the scientific literature. During the last 10 years the need to correlate aerosol exposure and biological effects has become especially important due to rapid development of a new, revolutionary indu...

Brown bullheads (Ictalurus nebulosus) were sampled from sites in the Buffalo and Detroit Rivers where fish are exposed to high levels of sediment bound polycyclic aromatic hydrocarbons, and suffer from an elevated frequency of liver cancer. DNA was isolated from the livers of these wild fish and from control specimens which were raised in clean aquariums. DNA was enzymatically digested to norma...

The Fukushima Daiichi Nuclear Power Plant (FDNPP) accident that occurred after the Great East Japan Earthquake in March 2011 released large quantities of radionuclides to the environment. The long-term effects of radioactive cesium (Cs) on biota are of particular concern. We investigated the accumulation of radioactive Cs derived from the FDNPP accident, and chronic effects of environmental rad...

A decrease in genome size was found in the hemiclonal hybridogenetic frog Rana esculenta (R. ridibunda x R. lessonae) from areas of radioactive contamination that resulted from the Chernobyl fallout. This genome reduction was of up to 4% and correlated with the background level of gamma-radiation (linear regression corresponded on average to -0.4% per doubling of radiation level). No change in ...

The environmental issues concerning uranium mining and milling have long been paid considerable attention in wide aspects in the world [1–4]. It is well known that the industrial activities of mining and milling of uranium ores can lead to release of a tremendous amount of radioactive pollutants (wastewater and tailings, as representative carrier) that consist typically of U and Th compounds. A...

Many pyrotechnic devices contain barium nitrate which is used as an oxidizer and colouring agent primarily for green-coloured fireworks. Similarly, strontium nitrate is used for red-coloured pyrotechnic effects. Due to their chemical similarities to radium, barium and strontium ores can accumulate radium, causing a remarkable activity in these minerals. Radium in such contaminated raw materials...

The greatest natural resource on the Planet, the World Ocean is both the origin of most life forms and the source of survival for hundreds of millions of people. Pollution of the oceans was an essential problem of the 20th century that was associated with the rapid industrialization and unplanned occupation of coastal zones It continues to be a concern in the 21st century. The most serious envi...

The twenty years period past after the contamination with radionuclides in 1986, as a result of the accident in the Chernobyl’s NPP, allowed the accumulation of rich data base for the radiation status of the soils in Bulgaria. Objective of many years studies were virgin soils from high mountain areas, hilly and flat (the region of Kozlodouy NPP and the Danube river valley). Ceasium-137 and stro...
