In this study, 16 polycyclic aromatic hydrocarbons (PAHs) were analyzed in 157 concurrently collected soil samples in 2005 over China. Higher concentration of ∑16PAHs was found in urban soil, followed by rural and background soil. The results indicated that PAHs in Chinese surface soil showed a primary distribution pattern, which was confirmed by the positive correlation with emission inventory...

Seasonal investigation on seven species of fresh water turtles was done from July 2013 to June 2014 in some parts of Odisha. Analysis of variance with three factors as place, species and season showed significant differences among themselves F = 2852.1,198.61 and 509.38,P ≤ 0.01). Seasonally the four species of turtles like Lissemys punctata, Nilsonia gangeticus, Chitra indica and Pangshura ten...

Fishing is one of the best known and practiced human activities. However, you should remember that, when casting the hook from the riverbank or grasping it to add bait, fishermen run a real risk of injury if the hook punctures the skin.Briefly we describe a case where a young, 32-year-old fisherman who was reeling the hook back to shore when it hit him in the face and embedded itself in his upp...

Agriculture is a key contributor to poor water quality, but the sources of sediment and nutrient losses from agricultural catchments – including riverbank erosion are highly variable. Riverbank particularly difficult quantify control. Here, we developed quick assessment approach rates associated loading into waterways using airborne LiDAR combined with field-collected data. We applied this expl...

quaternary sediments have occupied most of the agricultural and natural resources of urmia region. recognition of physicochemical and mineralogical properties of these soils is essential to optimum and stable use of these lands. in this study, eight soils profiles excavated on quaternary sediments of urmia region were investigated. the results showed that little thickness and evolution of studi...
