Industrial oil spills into aquatic environments can have catastrophic environmental effects. First responders to oil spills along the coast of the Gulf of Mexico in the southern United States have used spunbond nylon fabric bags and fences to separate spilled oil and oil waste from contaminated water. Low area mass density spunbond nylon is capable of sorbing more than 16 times its mass in low ...

An excess level of heavy metals are exposed into environment by industrial waste and fertilizers causes serious concern in nature as they are nonbiodegradable and accumulate at high levels. Heavy metals such as Pb, Zn, Cd, As etc. are one of the most toxic pollutants which show hazardous effects on all living livings. The prevailing purification technologies used for removal of contaminants fro...

Studies are reviewed that demonstrate the leaching of Cu, Cr, and As from pressure-treated wood in aquatic environments. The metals leached out accumulate in sediments near the wood (particularly bulkheads, which have more surface area for leaching than dock pilings). The metals also accumulate in organisms, including epibiota that live directly on the wood and benthic organisms, which live in ...

Most often, our waterways are being polluted by municipal, agricultural and industrial wastes. When this happens, much of the available dissolved oxygen is consumed by aerobic bacteria in decomposing the waste, thereby robbing other aquatic organisms of the oxygen they need to live. In this paper, we consider the solution of the optimal control problem for the modified Dissolve Oxygen(DO)/ Biol...

Heavy metal pollution represents an important environmental problem due to the toxic effects of metals. Their accumulation throughout the food chain leads to serious ecological and health problems. The remediation of environments metal contaminated through physico-chemical methods present major disadvantages such as high energy consumption, high costs and incomplete removal of metal ions. Bioso...

infertility is believed to be part of the various medical problems that has increased up to 50% since 1955 in the world and 10-15% of couples are already suffering from it. development of industrialization and urbanization in human societies have dramatically changed the human life style and led gradually to the increase of various environmental risk factors. humans are exposed to polluted air,...

Antimicrobials are widely used, not only for treating human infections, but also for treatment of livestock and in fish farms. Human habitats in Southeastern Asian countries are located in close proximity to aquatic environments. As such, the human populations within these regions are at risk of exposure to antimicrobial resistant bacteria, and thereby disseminating antimicrobial resistance gen...

diazinon pesticide and its metabolites have been identified in aquatic systems worldwide. it was related to toxicity for aquatic organisms, animals, and humans. waters contaminated with such persistent insecticides should be treated with suitable treatment processes. in this research, diazinon removal from aqueous solutions by the photo–fenton–like process (uv/h2o2/fe0) was investigated. this e...
