چکیده

With highly increasing demand for plastic use, however, environmental contamination by plastic litters has become an emerging issue. Globally, large quantity of used plastic is landfilled or emitted directly to the aquatic and terrestrial environments, albeit a part of the plastic is recycled or incinerated as energy source. In particular, microplastic debris that are smaller than ۵ mm are considered to be emerging contaminants of global concern. In the past decade, however, most of the researches ok impacts of microplastic contamination have been focused on the marine ecosystem, whereas very limited ones on the terrestrial ecosystem. Soil can be considered as a major sink and a carrier of microplastic contaminants to the aquatic environment. Most sources of microplastics in the soil environment are entered via a variety of routes and subsequent fragmented and spread to the surrounding environments, vertically and horizontally. Purpose soil is a thin coating of matter that covers the earth's surface, formed through the process of rock weathering. It is a natural flater for impurities in groundwater and is very important to human health. Recently, some studies from around the world have confirmed that the presence of microplastics in soil is increasing. However, most of these studies only examined the impacts of soil microplastic contamination one or two soil health indicators, rather than than study all the soil health indicators at once. In addition, there are negative impacts on soil biota, which in turn would cause concerns of human health by affecting the food web. Here, we provide an overview of characteristics, research trend, analytical methods, migration and degradation processes, effects on soil biogeochemistry, and interaction with soil organisms of microplastics suggesting the importance of ongoing research impacts of microplastics on the terrestrial ecosystem.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
