INTRODUCTION Rubber is a material that is widely used in all kinds of human activity. Rubber properties are modified by addition of chemical substances and ingredients causing physical and chemical modifications. The ingredients modify rubber hardness, durability and impact st rength; increase its resistance to wearing, oils, oxygen, solvents, heat, and cracking, which makes rubber more suitable for the use in various application ...

Introduction Benzene is formed in gasoline in the process of oil refining and gasoline production. Determination of benzene in gasoline is an important task, because ben zene and its products reacting with the products of incomplete combustion of gasoline are highly toxic. Moreover, the presence of benzene increases fouling that eventually may damage the engine . Therefore, regulations impose lim it on the content of benzene in gasoline in many countries, and international standards exist to come up to this ...

Within the globalized pharmaceutical raw material supply chain, there is an increasing public health concern of raw material adulteration, contamination, or mislabeling, especially with recent incidents such as the adulteration of heparin. This has driven regulatory bodies to update their guidelines. Chapter 5.33 of the latest GMP guidelines for Medicinal Products for Human Use, provided by the European Commission (EC), entitled "Eudralex," specifies that "there should be appropriate procedures or measures to ...
