يمكن أيضًا تسمية الكسارات المتنقلة بمحطات التكسير المتنقلة، والكسارات المتنقلة، وما إلى ذلك. إنها منتج لا مفر منه لتكنولوجيا التكسير عالية التقنية في العصر الجديد، وتتمثل ميزاتها الرئيسية في إمكانية تشغيلها متنقلًا، ويمكنها السير بحرية، وأكثر من ذلك مريحة للتحولات، مما يضمن أن المعدات بينما يكون الإنتاج آمنًا، فإن عملية العمل أكثر موثوقية.
Zn Cu and Pb speciation was performed according to the modified methodology of Tessier et al Anal Chem 51 844 851 1979 in two different sandy and clay soils with background HM amounts and in soil samples amended with aerobically digested SSC to find out the predominant species of the investigated HM and to predict their potential
Knowledge of the essential and nonessential elements distribution and behavior in Antarctic fish is important for understanding the essentiality and requirements of minerals in the diet of those species as well as the bioavailability and storage of trace minerals in the tissues of fishes In this study the levels of zinc copper cadmium and lead in muscle intestine liver
