Water is the key of national development. Wherever a spring has been dried out or a river has changed its course, the area’s people have migrated and have been scattered and the area’s civilization has lost its brilliance. Today, air pollution, global warming and ozone layer damage are as the problems of countries, but certainly in the next decade the shortage and pollution of waters will be im...

Aghdarband coal mine, located in NE of Iran, with annual coal and waste production capacity of about twenty million and six thousand tons, respectively, causes the increase of the concentration of some heavy metals in the soil and surrounded sediments. This paper deals with geochemical distribution and environmental effects of the heavy metals on the sediments around the mine, using geochemical...

abstractbackground and objectives: considering progressive growth of industry and technology, the accumulation of environmental contaminants, especially heavy metals (hms) in the soil is of increasing worldwide concern about the probable soil pollution risks. the perception of pollutants spatial distribution pattern and recognition of factors which control this pattern and identification of pro...

The use of plastic materials such as polypropylene and poly ethylene has faced an enormous increase in the contemporary world. This factor world causes damage to environment. wanted reuse this waste a productive way that reduces ecological occurring One best ways found after numerous researches waste, is utilise them enhancing properties clay soil further using it paving roads. paper focuses on...

The diffusion of Coronavirus disease (COVID-19) impacted the whole world, changing life habits billions people. These changes caused an abundant increase in personal protective equipment (PPE, e.g., masks and gloves) use by general population, which can become a concerning issue plastic pollution.

Mulching is used to improve the condition of agricultural soils by covering the soil with different materials, mainly black polyethylene (PE). However, problems derived from its use are how to remove it from the field and, in the case of it remaining in the soil, the possible effects on it. One possible solution is to use biodegradable plastic (BD) or paper (PP), as mulch, which could present a...

Almost all fast-moving consumer goods (FMCG) use plastic-based packaging because it is easy to shape, can be colored, and raw materials are cheap. Aqua bottle uses PET (Polyethylene Terephthalate) plastic, the problem occurs when disposable becomes waste, difficult decompose, complex recycling process resulting in environmental pollution even become one of factors climate crisis. presents Life ...

Single-use plastic is having a significant environmental impact and its reduction mandatory step to reduce pollution worldwide. Indeed, the time that item can persist in environment very long it well known produce devastating effects particular seas oceans. Moreover, production, use disposal of items have also on greenhouse effect; this be estimated life cycle approach, by evaluating their carb...

With the increasing awareness of environmental protection, problem "white pollution" caused by waste plastics has become more and important to all countries, restriction plastic ban a global consensus, which ushered in good opportunity for biodegradable industry. Polybutylene adipate-butylene terephthalate (PBAT) is one most widely used at present. This paper mainly introduces synthesis, modifi...
