Background: In recent years, the occurrence and fate of environmental pollutants has been recognized as one of the emerging issues in environmental chemistry. A survey documented a wide variety of these pollutants, which are often detected in our environment and these are a major cause of shortened life spans and global warming. These pollutants include toxic metal, pesticides, fertilizers, drugs, and dyes rele Read More

Background: The protection of the ecology is an important task to control and restore the quality of environmental media through the reduction or prevention of the pollutants. Due to the growing awareness of safety, health and environmental issues, the use of non-toxic, clean and ecofriendly methods in the synthesis of nanoparticles has emerged out of necessity. Methods: In this article, the following concepts were considered Read More

Background: Polycyclic aromatic hydrocarbons (PAHs) are common environmental contaminants consisting of two or more fused benzene rings. PAHs can be introduced into foodstuffs through different ways, such as smoking, roasting and grilling for meat and fish, absorption from the environment for edible oils, chemical treatment of crops for plant-based products, or contamination through packaging during storage.

Background: Bisphenols are major industrial chemicals that have raised public concern due to their endocrine disrupting properties and toxicity. Sample preparation is the most critical step for the determination of bisphenols, especially if the analyst has to deal with environmental samples which are complex matrices and the co-extraction and co-elution of other relevant compounds results in the enhancement or suppressi Read More

Background: Nuts have been incorporated into guidelines for healthy eating since they contain considerable amounts of antioxidants and their effects are related to health benefits since they contribute to the prevention of nutritional deficiencies. The micronutrient characterization is based mainly on the determination of phenolics, which is the most abundant class of bioactive compounds in nuts. Terpenes constitute another Read More

Background: Conventional analytical methods for phosphorus and sulfur determination in several matrices present normally analytical challenges regarding inaccuracy, detectability and waste generation. Objective: The main objective is proposing a green and feasible analytical method for phosphorus and sulfur determination in animal feed. Methods: Synergic effect between microwave and ultraviolet radiations during sam Read More

Background: Lithocarpus litseifolius (Hance) Chun (L. litseifolius) has been used for treating diabetes, allergic and inflammatory diseases, and hyperlipidemia in folk medicine. Previous studies have shown that the main active ingredients of its leaves are flavonoids. However, to the best of our knowledge, the stem of L. litseifolius has not been investigated for its constituents yet. The stems of the decaying plants fall every y Read More

Background: Ocimum basilicum L. seeds, is commonly also known as Takhmaria in Gujarat. It is a common constituent present in fruits, plant-derived beverages, vegetables, wheat, sprouts, and some seasonings. Objective: A simple, specific, precise, accurate, and sensitive method for the quantification of apigenin by reverse-phase high-performance liquid chromatography (RP-HPLC) was developed and validated. Methods: Read More

Background: The possibility of estimating the age of fossil bones using only classic thermogravimetry, on the basis of proper % mass loss ratio values, has been widely considered in the past years. Objective: Our research has brought some innovations to the previous background, by using chemometric methods and by processing the numerical files of whole thermogravimetric curves. The objective of this paper is the selec Read More

Background: Hydrogen peroxide (H2O2) is widely used in various fields and it plays a quintessential role in a variety of biomolecular processes. H2O2 concentration level is an essential biological parameter in monitoring and maintaining the physiological balance of a living cell, and its variation causes some related diseases. Therefore, it is extremely significant to fabricate biosensor with low cost, which can quickly, acc Read More

Background: Platinum (Pt), palladium (Pd), rhodium (Rh) and iridium (Ir) are platinum group elements (PGEs) and also important elements of geochemistry and environmental chemistry with the similar physic-chemical properties, which have been widely used in industry and laboratory. However, due to the low abundance and inhomogeneous distribution in natural ore as well as the nugget effect, the accurate determina Read More

Background: It is demonstrated that for a junior research faculty in India, proper guidelines and funding resources are required to publish research articles in the Open Access (OA) journals. Recently, many of the important scientific journals are turned out to be OA journals. When we need to publish in an OA journal, the funding support for article processing charge (APC) is uncertain due to the limited funds or absence of instit Read More
