Environmental Organic Photochemistry: Advances and Perspectives
2013
This review is a survey of recent advances in environment related aspects of organic photochemistry. Besides presenting gen- eral concepts, the manuscript is mainly focused on the photoreactivity of natural organic matter, and on the photochemistry of anthropo- genic substances under natural light irradiation.
Photochemical sample treatment: A greener approach for PCBs analysis in sediments
2012
Electrical installations and industrial outlets are the major source in environment of chlorinated organic compounds. These are distributed in several geographical areas through long-range atmospheric transport and deposition. Additionally, chlorinated organic compounds can be introduced in the food chain and reach the consumers in very high levels. Besides toxicological studies on PCBs, recent research is focusing on more sophisticated analytical methods for PCBs detection. Distribution and dispersion of PCBs mostly occur through air, water, soils, and sediments. The latter are complex matrices whose analysis often involves costly extraction and purification procedures. In particular, PCBs…
Environmental Aspect Concerning Phthalates Contamination: Analytical Approaches and Assessment of Biomonitoring in the Aquatic Environment
2023
This review is a survey of recent progress in studies concerning the impact of phthalic acid esters in aquatic organisms. After introducing the classification, properties, sources, fate, and toxic effects related to phthalates, an overview of the techniques of extraction and analysis of these substances is provided. As a result, the general concepts of environmental bioindicators, biomonitoring systems, and other concepts related to phthalate contamination in the aquatic environment are presented. Recent bioaccumulation data of different phthalates are summarised in a table and organised according to the type of organism, tissue, and geographical area of sampling. Bioindicator organisms tha…
Umowa o udzielenie zamówienia na świadczenia zdrowotne
2018
Umowa o udzielenie zamówienia na świadczenia zdrowotne, potocznie często rozumiana jako kontrakt, znajduje wyłączne zastosowanie w sektorze ochrony zdrowia. Umowa ta stanowi podstawę świadczenia pracy (usług) przez personel medyczny w podmiotach leczniczych, która aktualnie jest już utrwaloną formą angażu przede wszystkim lekarzy i pielęgniarek, którzy decydują się na wykonywanie swojego zawodu w formie praktyki zawodowej. Problematyka zamówienia na udzielanie w określonym zakresie świadczeń zdrowotnych stanowi przedmiot ustawy o działalności leczniczej. Pełna nazwa tej umowy nie jest wprawdzie określana przez ustawę, lecz analiza treściowa art. 26-27 przywołanej ustawy pozwala na jej wypro…

Identification of Polycyclic Aromatic Hydrocarbons (PAHs) in the black crusts of Sicilian stone monuments: distribution and sources
2004
Polycyclic Aromatic Hydrocarbons are a family of compounds with known carcinogenic potential; their properties of lipophilicity, low water solubility and adsorption to particles and sediments make them a potentially dangerous group of chemicals and a threat to the environment and its bio-resources. The concentrations of total Polycyclic Aromatic Hydrocarbons (PAHs) and 19 individual compounds in 8 black crusts sampled from historical building of Palermo (Italy) were analyzed, by gas chromatography/mass spectrometry (GC/MS) in selected ion monitoring (SIM) mode. PAH concentrations ranged from 78 to 9798 g/Kg of dry matrix. The resulting distributions and molecular ratios of specific compo…
