The rapid growth of the human population in recent decades has resulted intensive development various industries, urban agglomerations and increased production medicines for animals humans, plant protection products fertilizers on an unprecedented scale. Intensive agriculture, expanding areas newly established industrial plants release huge amounts pollutants into environment, which, nature, ar...

Habitat valuation methods were implemented to support remedial decisions for aquatic and terrestrial contaminated sites at the East Tennessee Technology Park (ETTP) on the US Department of Energy (DOE) Oak Ridge Reservation in Oak Ridge, TN, USA. The habitat valuation was undertaken for six contaminated sites: Contractor's Spoil Area, K-901-N Disposal Area, K-770 Scrapyard, K-1007-P1 pond, K-90...

Campylobacter jejuni and C. coli are the main causes of gastrointestinal diseases in humans even in industrialized countries affecting public health. The aim of the current study was to evaluate the occurrence and antibiotic resistance of C. jejuni and C. coli in chicken meat, beef, mutton and water buffalo meat slaughtered in Ahvaz city, Iran. A total of 380...

Despite the influence that amphibians have on the flow of energy and nutrients in ecological systems, the role that amphibians play in transporting contaminants through food webs has received very little attention. This study was undertaken to investigate bioaccumulation of trace elements in amphibians relative to other small aquatic organisms in a contaminated wetland. We collected bullfrog la...

Bacteria can develop a variety of cellular mechanisms for acquiring resistance against antibiotics, including genetic mechanisms. Both commensal and pathogenic bacteria become resistant to every new antibiotic within few years of introduction. In recent years, antibioticresistant bacteria are being widely spread in nature. This can be due to the irrational use of sub-lethal concentrations of an...

Contamination of industrial and municipal water supplies with arsenic (As), selenium (Se), and mercury (Hg) can occur from natural deposits, industrial discharge, runoff from mining, landfill and agricultural operations. Consumption of contaminated water can cause skin damage (As), kidney and nervous system damage (Hg) and numbness in the fingers and toes (Se).1 The U.S. Environmental Protectio...

The degradation of water resources is related to anthropic actions such as rapid urbanization and industrial agricultural activities with inefficient land use occupation management. Water pollution caused by organic inorganic contaminants represents a current challenge for researchers humanity. One the techniques used remove pollutants from aquatic environments bioremediation, through metabolis...

Membrane processes are used in various felds such as the environment, agriculture and different industrial sectors. These clean techniques are often adopted for directed processes such as treatment, recovery, valorization and separation. In this review article, the theoretical principles and the different classifcations of liquid membranes, such as supported liquid membra...

Microorganisms play critical roles in the various aquatic systems forming microbial mats. The microbial mats are held together and bound to their substrates by slimy extracellular polymeric substances (EPS) having various applications which they secrete. They use all types of metabolism and feeding strategy that have evolved on Earth, and have shown immense use in various industrial application...
