The Study of Water Quality of Several Local Sources

Abstract

Aim: The aim of this study is to analyze the water quality of several local sources from the Toplița-Deda region, as well as from the Gheorgheni basin, in order to inform the population about the water quality and about the importance of the drinking water control.

Method: Repeated water samples were collected from a total number of 41 sources in the two studied regions during 2010. A multiparametric colorimeter, Hanna Instruments C99 was used to determine certain physical and chemical parameters. A number of current and specific microbiological analyses were also carried out.

Results: The average values and the percentage of the positive samples with values above permitted limits were calculated. The highest accepted levels were based on Law no. 458/2002 regarding drinkable water quality. Among the mineral indicators iron exceeded the limit in 18.18% and water samples were poor in fluoride (83.65%) and in iodine (98.18%). A small percentage of sources (3.63%) indicated pollution, 10.9% had high nitrate level. Analyzing the microbiological content, our water samples were within the drinkability limits required by law.

Conclusion: Our study emphasizes the importance of monitoring water supplies, the awareness of the water quality according to mineral composition, pollution estimation and microbiological characteristics in order to prevent the unexpected influence on the health status of the consumer population.

Coronary Plaque Geometry and Thoracic Fat Distribution in Patients with Acute Chest Pain – a CT Angiography Study

Abstract

The aim of our study was to investigate the correlation between volumes of thoracic fat distributed in different compartments and the geometry of vulnerable coronary plaques assessed by coronary computed tomography angiography (CCTA), in patients with acute chest pain.

Methods: This was a non-randomized, observational, single-center study, including 50 patients who presented in the emergency department with acute chest pain who underwent 128-slice single-source CCTA. Plaque geometry was evaluated in transversal and longitudinal planes, and the assessment of adipose tissue was performed using the Syngo.via Frontier (Siemens AG, Healthcare Sector, Forchheim, Germany) research platform.

Results: Eccentric plaques presented a significantly higher incidence of spotty calcification (40% vs. 22%, p = 0.018), whereas positive remodeling, volume of low attenuation plaque, and incidence of napkin-ring sign were not significantly different between the study groups or in ascending versus descending plaques. The volume of pericoronary fat around the plaque was significantly larger near eccentric lesions (707.68 ± 454.08 mm3 vs. 483.25 ± 306.98 mm3, p = 0.046) and descendent plaques (778.26 ± 479.37 mm3 vs. 473.60 ± 285.27 mm3, p = 0.016). Compared to ascending lesions, descendent ones presented a significantly larger volume of thoracic fat (1,599.25 ± 589.12 mL vs. 1,240.71 ± 291.50 mL), while there was no significant correlation between thoracic fat and cross-sectional eccentricity.

Conclusions: The phenotype of plaque distribution and geometry seems to be associated with a higher vulnerability of coronary lesions and may be influenced by the local accumulation of inflammatory mediators released by the pericoronary epicardial adipose tissue.
