This study provides important data on the distribution, sources and ecological risks of polycyclic aromatic hydrocarbons (PAHs), in surface waters and sediments collected from dam reservoirs on middle and lower course of the Olt River, the main tributary of the Danube, until the discharge into the Black Sea. A wide variation range of total PAHs con...

Chestnut (Castanea sativa Mill.), a valuable fruit crop, is cultivated in small areas in Romania, mostly in the west, where the moderate continental climate has a slight Mediterranean influence. This work aims to investigate the bioactive characteristics (total polyphenols, total flavonoids and antioxidant activity), individual polyphenolic composi...

The tremendous impact of natural and anthropogenic organic and inorganic substances, continuously released into the environment requires a better understanding of the chemical status of aquatic ecosystems. Water contamination monitoring studies have been performed for different classes of substances, in different regions of the world. Reliable anal...

This study aimed to investigate two classes of POPs, namely PAHs and PCBs in different environmental matrices (vegetation, soil, water, and sediments) collected from two industrial areas of Romania: (1) Copșa Mică, an area with a history in industrial activity for the production of carbon black from methane gas (Carbosin SA) and the production of P...

The present study aims to investigate the distribution of organic contaminants in different species of fish (catfish - Silurus glanis, crucian - Carrassius gibelio, perch - Perca fluviatilis, slug - Rutilus rutilus, bream - Abramis brama) taken in the period 2019 - 2020 from the middle and lower course of Olt River, in the localities of Cornet, Str...

In this work two types of materials have been used to develop electrochemical sensor for Gly detetction. The gold nanoparticles (AuNPs) modified graphene (Gr) nanomaterials showing high sensitivity as non-enzymatic material for sensor modification, while the molecularly-imprinted polymer (MIP) showing both high sensitivity and high selectivity towa...

Water contamination monitoring studies were performed for different classes of substances in different regions of the world. Reliable analytical...

Propolis, a complex bee product, is a source of numerous bioactive principles, beneficial for human health, therefore it is intensively studied. In the present work, extracts of propolis from Bihor Romanian County were studied to identify the relationship between the polyphenolic derivatives profile and their antioxidant and antimicrobial activity....

Apple (Malus domestica Borkh.), a popular and widely cultivated fruit world-wide, contains bioactive compounds responsible for their health benefits. Here we report the amounts of some bioactive compounds: two major triterpenes (oleanolic and ursolic acids) and polyphenols (phenolic acids, flavan-3-ols, flavonoids and t-resveratrol), together with...

Organic contaminants (OCs) accumulate in the environment as a result of anthropogenic activities (industrial, agricultural, and household activities as well as auto traffic) and produce negative effects on the environment and humans. [...]

This work reports the application a sensor array based on modified screen-printed carbon electrodes (SPCE) in conjunction with chemometrics for wine discrimination and classification according to the varietal origin of the grapes.
