The blue hyacinth is a bulbous perennial herb in the Lilliaceae family, grown for its showy and fragrant springtime flower display. Garden chrysanthemums are tender perennials in the Asteraceae family in double-flowered forms. Flame atomic absorption spectrometry (FAAS) was used for the quantitative determination of metals in this matrix. Also, the refraction indexes and conductivity were measured using Abbe refractometer and LF 340-A conductometer, for the characterization of the obtained mixtures, respectively for correlation with the mineral content. It was observed that that iron concentrations are higher in blue hyacinth extract and macerates than chrysanthemum.

The therapeutic value of water and mud from the Salt Lake (Lacu Sarat) is known for a long time by the inhabitants of this region, but yearly a lot of tourists come here and most of them for a cure. This paper presents the results of studies for the duration of two years, with the students of the Department of Chemistry research group. These were analyzed the total contents of Fe, Cu and Cr in the sapropelic mud, for analytical characterization of the therapeutic and used mud. The methods applied were the titrimetric and molecular absorption spectrometry ones. The obtained results led us to evidence an ionic exchange between the therapeutic mud and the human organism at the epithelial level. In the field of natural cure, Romania has a special position thanks to its natural cure factors: mineral and thermal waters, therapeutic mud and lakes. Variety of natural resources and quality ranks Romania on the first place in Europe.

The aim of this study was to analyze quantitatively the distribution of heavy metals and ascorbic acid in Allium plants: Allium sativum L. (garlic) and Allium cepa L. (onion). Heavy metals accumulation in garlic and onion was quantified by flame atomic absorption spectrometry (FAAS) after the chemical mineralization of the samples with nitric acid and hydrogen peroxide in a Digesthal device. To determinate of vitamin C we used a titrimetric method with potassium brommat-bromide solution in acid medium, when vitamin C is oxidized to dehidroascorbic acid by bromine. Our results indicate a high concentration of vitamin C in leaves of the studied Allium plants.

As trace elements some of them (e.g. copper, selenium, zinc) are essential to maintain the metabolism of human body, although at higher concentrations they can lead to poisoning. This work is going to present the results obtained from the determinations of grapes and melons extracts. For obtaining the extracts, Soxhlet extraction, maceration and ultrasonic method were used. A Shimadzu atomic absorption spectrometer (Model AA 6200) equipped with air-acetylene flame, was used to determine the Cu, Mn and Zn concentrations. Also, the refraction indices and relative density were measured, using an Abbé refractometer and a picnometer. The obtained results show that the highest Cu and Zn content is in the melons skin, the highest Mn content is in the grapes skin. The refraction indices and the density's values are very close to that from the Romanian standards. In the last part of this study we are

These levels were compared to those available for other surface waters. The studied water samples were analyzed by gas chromatography with mass spectrometer detector (GC-MS) and by gas chromatography with electron capture detector (GC-ECD).

Vegetables grown at contaminated sites could take up and accumulate metals at concentrations that are toxic. Heavy metals are known to pose a variety of health risks such as cancer or mutations. The objective of this study was to analyze quantitatively the distribution of heavy metal and the organochlorine pesticides in Capsicum annuum L (pepper) grown in two different places, one indoors with no pollutants using soil from Babadag forest far from the city and second place is an urban garden from Constantza city expose to the city pollution. Metals were detected at mg/Kg levels and OCPs at ng/kg levels.

Therefore, the effect of storage time on the stability of low and high fat butters was evaluated. Samples were stored at +4° C at dark, and the reaction was observed by measuring peroxide value (PV), free fatty acids (FFA), refraction index, saponification value and water content. The peroxide values increased in the time, but this was not significant. PV values in both types of butter remained under permitted limits during the first three weeks of storage, followed by an unacceptable increase by the end of the shelf period. The storage time did not significantly influence the profile of free fat acids, even that little variations were observed.

In order to estimate the pollution level and the danger created by this phenomenon, some analyses are required with regard to determining the concentration of the pollutant metals in plants samples. The investigated metals were determined by flame atomic absorbtion spectrometry in different types of vegetables and fruits, after the chemical mineralization of the sample with a Digesdahl device. These levels were compared with those from literature.

High pressure liquid chromatography with fluorescence detector (HPLC), respectively gas chromatography with electron capture detection (GC-ECD) was used for the determination of 7 polycyclic aromatic hydrocarbons (PAHs) and 9 organochlorine pesticides (OCPs) in coffee samples. It was found that concentrations of PAHs in coffee samples varied from 0.001 µg/Kg to 90.732 µg/Kg. B[a]P was absent in the green coffee samples. The detection limits ranged from 0.02 ng/kg to 0.04 ng/kg and quantification limits were 0.2 ng/kg. Calibration and recovery studies gave satisfactory results. Concentrations of OCPs in coffee samples varied from 0.001 mg/Kg to 0.007 mg/Kg. The methods provide a rapid and accurate determination of these organic compounds in coffee samples.

Good quality measurements are essential to control and maintain milk products and processes quality, both in manufacturing, trade and in research. The presence of toxic elements in powdered and liquid milk may create significant health problems for people. The aim of this paper was to determine the content of major and minor elements in different milk samples, sold in major supermarket chains in Romania. Inductively coupled plasma atomic emission spectrometry (ICP-AES) was used for the quantitative determination of elements in this matrix. Analyses were performed after the chemical mineralization of the samples with nitrogen acid. Detection limits ranged from 0.4 to7.03 ng/g.

A fluoride ion selective electrode was used to determinate the fluoride content in tea samples (Hypericum perforatum, Tilia cordata and Camellia sinensis). Total fluoride contents of tea leaves were determined to be 91.1-162 mg/kg d.w., and 0.095-1.450 mg/L in tea infusions and the percentage of fluoride infused for analysed tea leaves ranged from 7.2% to 89.5%. The study shows that there are differences between the fluoride percentage in the tea infusions and about 85% of fluoride in tea leaves was released into Hypericum perforatum and Camellia sinensis, after 30 min of brewing. Tilia cordata shows a slow growth during the infusion process, having the lowest percentage of fluoride.

The oils used for blends were linseed oil, grapeseed oil, and coconut oil. The physico-chemical properties demonstrated the superior features for oil blends, like lower acidity (measured by acid value) and higher stability to autoxidation (measured by peroxide value and refractive index). The best combination for sunflower oil was with coconut oil (lower acidity, higher stability to autoxidation). For a supplementary improvement of properties, especially for the preservation of oils and oil blends, we tested the lovage (Levisticum officinale) extract as additive. The obtained additivated mixtures demonstrated better quality characteristics, which recommend them for the human consumption.
