Microplastics as a Threat to Aquatic Ecosystems and Human Health.

The threat posed by microplastics has become one of the world's most serious problems. Recent reports indicate that the presence of microplastics has been documented not only in coastal areas and beaches, but also in water reservoirs, from which they enter the bodies of aquatic animals and humans. Microplastics can also bioaccumulate contaminants that lead to serious damage to aquatic ecosystems.

Estimation of Target Hazard Quotients and Potential Health Risks for Toxic Metals and Other Trace Elements by Consumption of Female Fish Gonads and Testicles.

The aim of this study was to assess the risk to consumers associated with the intake of toxic metals and other trace elements in diets that include the female gonads, testicles, and muscles of four popular freshwater fish species in Poland—common bream (Abramis brama L.), European perch (Perca fluviatilis L.), common roach (Rutilus rutilus L.

Influence of Water Treatment and Wastewater Treatment on the Changes in Residues of Important Elements in Drinking Water.

Drinking water is the essential medium for food production, and is also needed for direct consumption; while it must be free of harmful substances, it also must have a composition that is beneficial to health. The aim of this study was to evaluate the influence of water and wastewater treatment on reducing the concentrations of zinc (Zn), nickel (Ni), iron (Fe), manganese (Mn), copper (Cu), lead (Pb), and arsenic (As) in the Western Pomerania Voivodeship in Poland. The research was carried out in 2017-2019.

Endocrine-disrupting organochlorine xenobiotics in fish products imported from Asia-an assessment of human health risk.

The sources of endocrine-disrupting persistent organochlorine compounds (OC) are environmental pollutants. Contaminated food is a direct result of environmental pollution, and fish are considered as the main source of OC in the human diet. This study aimed to analyze the contamination of imported fish fillets with organochlorine pesticides (OCPs) and polychlorinated biphenyl (PCB) congeners in the context of potential health risks of consumers in Poland in the light of the new tolerable weekly intake (TWI) values.

SYNTHESIS AND ANTIMICROBIAL PROPERTIES OF NEW MANDELATE IONIC LIQUIDS.

Novel mandelate ionic liquids with quartenary ammonium cations were synthesized and characterized. The compounds exhibit antimicrobial activity and the most potent one is of similar efficacy against Gram+ bacteria as its counterpart chloride. On the other hand, the mandelates are much less active against Gram-bacteria and fungi.

Long-alkyl-chain quaternary ammonium lactate based ionic liquids.

A new group of quaternary ammonium lactate based ionic liquids have been prepared and characterized. Didecyldimethylammonium (DDA) and benzalkonium (BA) D,L- and L-lactates are air-stable, hydrophilic, surface-active salts. They are very effective antibacterial and antifungal agents, especially the DDA lactates, against Streptococcus mutants and Candida albicans.

Molecular structure of some 3-amino-2-oxazolidinone derivatives.

It is generally accepted that the specific, energetically preferred conformation of a compound decides on the nature of interactions with pharmacological receptor. Therefore it is of basic importance to get an insight into such molecular parameters as charge distribution, most preferred conformations or the distances between specified points within a molecule. The structure of some 3-amino-2-oxazolidinone derivatives with the aid of NMR spectroscopy (13C and 15N) and X-ray analysis was investigated.

Intravenous amiodarone for cardioversion of recent-onset atrial fibrillation.

Background: Atrial fibrillation (AF) is one of the most common causes of hospital admission, with a prevalence of up to 5% of the population, increasing with advancing age. Emergency direct current cardioversion is the therapy of choice when arrhythmia leads to hemodynamic compromise, but in patients who are hemodynamically stable, antiarrhythmic drugs are usually given to restore sinus rhythm.

Hypothesis: The study was undertaken to assess the efficacy of intravenous amiodarone in cardioversion of recent-onset paroxysmal atrial fibrillation (AF).

[Hypertension and metabolic syndrome in population of one company. Monotherapy with amlodipine and doxazosin].

Unlabelled: In Poland diagnosing of hypertension (HA) and the efficacy of treatment of this condition is still insufficient. Consideration of the concomitant metabolic disorders may help to choose the best line of therapy.

Aim Of The Study: To determine the incidence of HA and concomitant lipid and carbohydrate metabolism disturbances in population of one company.
