This study was conducted in September 2014 to determine the effects of metal accumulation on the Odanata larvae which is a freshwater macroinvertebrate. Polluted area in the lower part of the mine founded on Umurbey Stream (Çanakkale, Turkey) and unpolluted area in the upper part of it are defined as the sampling stations. In this study, GSH (Glutathione), TBARS levels and Na, K -ATPase activit...

In recent years, there has been increasing interest in finding innovative solutions for the efficient removal of contaminants from water, soil and air. The present tutorial review summarizes the results of an extensive selection of papers dealing with electrochemical oxidation, which is proposed as an alternative for treating polluted wastes. Both the direct and indirect approaches are consider...

The association of arsenical poisoning with the development of skin cancer is well-known. In Malaysia, arsenic has been shown to coexist with tin in tin-mining land. Our preliminary investigation has shown that the level of arsenic in well water from a tin-mining area is high. We report 3 patients with cutaneous lesions typical of chronic arsenical poisoning such as hyperpigmentation, keratoses...

The “Software Package for Aerosol Size Distribution” is a novel graphical user interface application software used for the study of atmospheric aerosol size distribution from various aerosol models (Continental clean, Continental average, Continental polluted, Urban, Desert, Maritime clean, Maritime polluted, Maritime tropical, Arctic, Antarctic) and/or with different aerosol components (insolu...

Oil is the most widely distributed source of energy in the world and the largest-scaled environmental pollutant. Oil, oil products, and oil-containing industrial wastes pollution is ranked second place after radioactive pollution on account of their harmful action to ecosystems (Chernyakhovsky et al., 2004). Oil deposits in Russia are mainly located in the northern regions of the European part ...

An attempt has been made to evaluate pollution status and aquatic bio-resources of the Moirang river near its mouth in the Loktak Lake. The river water is considered polluted as it has high concentration of free CO2 (14.8 mg/l), nitrite-nitrogen (0.040 mg/l), inorganic phosphorus (0.107 mg/l and faecal coliform bacteria (162/100 ml). Aquatic bio-resources of the river include 24 species of fish...

Fog droplets in the atmosphere are first produced by the activation of cloud condensation nuclei (CCN), which are originally some ionic compound. Subsequently, the nuclei grow by vapor diffusion. Fog droplets are polluted through the activation process and successive diffusion growth and residence (post activation). We cannot distinguish the effects of the two pollution processes of natural fog...

The active biomonitoring (ABM) approach was investigated using species of indigenous (from a pristine site) and transplanted (to a polluted area) fish Carassius auratus as an indicator organism of water/sediment pollution in Taihu Lake, a highly urbanized and industrialized area. The biotransformation enzymes 7-ethoxyresorufin-O-deethylase (EROD), reduced glutathione (GSH) content, catalase act...

The vibrating dropping mercury ele·ctrode (VDME) is applied to the characterization of ionic species and to electroanalytical measurements of metal ion concentrations in water samples strongly polluted with different kinds of surface active substances (SAS). The Cd2+ /CdNTAsystem in citrate buffer solution at pH = 6 was chosen as a model for the effect of a preceeddng homogeneous chemical react...
