In abiotic degradation the action of light radiation is one of the most important parameters, because polymers undergo degradation due to the action of light (natural or artificial). The aim of this study was to investigate the degradation rate for samples of polypropylene (PP) modified with an organic pro-degradant submitted to ageing in a natural environment and to accelerated ageing test. Th...

this article presents the key insights about the environment and security links in the context of the persian gulf region. this research paper focuses on the challenge of finding a balance among development, armed conflicts and environmental degradation in the persian gulf region. environmental security challenges are human security, sustainable development and regional cooperation in the persi...

polyethylene is a synthetic polymer which is used in our daily life for different purposes. increased use of polyethylene causes severe environmental problems. there are different methods to decrease problem caused by polyethylene for example source reduction, incineration and land filling and all of them have their own drawbacks. so, the best way to reduce the problem caused by polyethylene is...

it is fair to say that the man by including agricultural, industrial activities and exploitation-of natural resources in his survival agenda is the most responsible of all for environmental changes. fundamentall development in various parts of a watershed is unavoidable and sometimes necessary. in recent years, large number of environmentally improper developments including new town development...

hexachlorocyclohexane, an organochlorine insecticide has been used in agriculture and public health programmes since a very long time. it is very resistant to degradation and thus accumulates in the environment for long time. a microbial consortium was developed in our laboratory which could degrade hexachlorocyclohexane very efficiently in water. a study was carried out to understand the biode...

background: poly chlorinated biphenyls (pcbs) are a class of chlorinated organic chemicals that do not easily degrade in the environment. this study was conducted to determine the effect of microwave rays, hydrogen peroxide, dioxide titanium and ethanol solvent on the degradation of pcbs. methods: a 900w domestic mw oven with a fixed frequency of 2450 mhz was used to provide mw irradiation. ray...
