Usage and their uncontrolled discharge in to the environment has caused lots of hazards to man, other organisms and the environment itself. Over past many decades there has been increasing global Concern over the public health impacts attributed to environmental pollution, more particularly, the encumbrance of hazardous diseases is increasing day by day. This paper reviews removal technologies (oxidation, coagulation flocculation, adsorption, ion exchange and membrane
Oil spill from cars, other vehicles and the machines are required to be stopped completely. Oil leak from the cars and other machines have posed bigger threat and these have become major contributors for water pollution. So, it is important to take care of cars and machines. Oil leak from the factories are also required to be stopped after the completion of the work in factories. These factories are required to apply all the ways for the safe disposal and
Wastewater is often classified as industrial or domestic wastewater. In waste water, it contains a lot of harmful pollutants liked: lead, manganese, cadmium, zinc and so on. As known, these pollutants are very dangerous when humans or other species consumed or even when exposed to it. These will affect human health and kill aquatic organisms. Many serious health effects including mutations, cancer, organ damage and death are caused by violet dye in large quantities.
They pose serious health risk and when these products are placed in landfills. As more and more e-waste is place in landfills, exposure to environmental toxins is likely to increase, thus resulting in elevated risks of cancer and developmental neurological disorders. This article provides an outer view on the awareness of the proper disposal of e-waste and its importance. It also puts a light n current trends which is been followed in the market in this subject. It is very much important for us to know how to use electronic products and further about its disposal in a formal way.
The ocean is nowadays undergoing numerous environmental issues that further lead to marine pollution. Marine pollution is a very serious environmental issue that most of the countries of the world encounter. Aquatic littering is considered as one of the major causes of marine environment. The misleading use of the marine environment is extremely impacting the marine life and ecosystems. Moreover, the total amount of toxins and debris discharged by human beings is incredibly increasing in today 's world.
Repetitive use of contaminated water leads to various biological disorder such as mutation, cancer and also causes liver damage. There are various methods to treat chromium (Vl) contaminated wastewater such as physical and chemical process7,9,13,18. Due to high cost these process
Environmental damage occurs throughout the stages of exploration, production, refining, transportation and end use consumption. Potential impacts include water contamination due to effluent of wash and cooling water discharges, seepage from storage and waste tanks, discharges of water effluents rich in inorganic salts without appropriate treatment and water contamination of oil spills which could be very catastrophic such as the incident of The Deepwater Horizon oil spill in the Gulf of Mexico in year 2010 and the oil spill resulting from the Gulf War in 1991. Also, this industry adds a considerable amount of NOx, SOx and particulate emissions and largely contribute to the soil and groundwater contamination resulting from the different chemical compounds and the produced
1. Introduction Water pollution due to the disposal of heavy metals continues to be a great concern worldwide. Consequently, the treatment of polluted industrial wastewater remains a topic of global concern since wastewater collected from municipalities, communities and industries must ultimately be returned to receiving waters or to the land (Weber et al, 1991). Heavy metals pollution occurs in much industrial wastewater such as that produced by metal plating facilities, mining operations, battery manufacturing processes, the production of paints and pigments, and the ceramic and glass industries. This wastewater commonly includes Cd, Pb, Cu, Zn, Ni and Cr (Argun and Dursun, 2008).
The e-coli bacteria which is present in human waste is very dangerous and drinking this water can cause harmful side effects . Waste dumping – The dumping of wastes like paper waste, food waste, plastic, rubber, metallic and aluminum waste in heavy quantities to the water bodies is another reason of pollution. These waste types take quite time to decompose. For example, paper takes about 6 weeks, aluminum takes about 200 years and glass takes even more years. Underground storage and tube leakages - Many liquid products (petroleum products) are stored or kept in metal and steel tubes underground.
1 INTRODUCTION Environmental pollution is one of the worldwide growing threats to human health and natural resources. One major cause of environmental degradation is air pollution due to natural and manmade sources. The main impacts of air contaminants include ground- level ozone, acid rains, greenhouse effect, climate change, ozone layer depletion and adverse health hazards. Benzene and toluene are organic compounds found in indoor air as a result of emissions from burning coal and oil, some household products which contain petroleum based chemicals like glues, paints, etc. Outdoor sources are like gasoline vapors at gasoline service stations, motor vehicle exhaust, emissions from industrial sources utilizing benzene and toluene, etc.
