THE INFLUENCE OF THE POLLUTANT FACTORS ON THE
GROUNDWATER QUALITY IN DEZMIR, COUNTY CLUJ
This paper represents a study of the groundwater quality of Dezmir,
county Cluj in the context of three main pollution factors: the municipal solid
waste landfill from Pata Rât, the heavy traffic in the area and the fertilizers and
pesticides used in agriculture.

SOME DETERMINATION METHODS OF
FORMIC ACID (HCOOH)
This paper is a short review about synthesis and determination
methods of formic acid from solution mixtures. Formic acid is used in many
industries such as textiles, natural rubber, in agriculture, as well as for
cosmetics, disinfectants, detergents, medicines, to controlling acidity against
microbial growth, fuel for power cells etc. In the same time is considered an
environmental pollutant, so the principal method for determination is the titration
process. Another methods mentioned in the literature are enzymatic method
and catalytic oxidation method.
Keywords: formic acid, formic acid determination methods, linear
voltammetry

RESEARCHES AND STUDIES OF THE INFLEUNCE OF
POLLUTING ATMOSPHERIC FACTORS ON THE BUILDING
MATERIALS USED AT THE ART MUSEUM IN CLUJ-NAPOCA
This paper represents an interdisciplinary study, and wishes to be an
attempt of restoration/conservation of cultural heritage. The purpose of the
paper is to observe study and classify the alteration and decay processes of the
building material used at the Cluj-Napoca Art Museum.
The alteration and decay processes can differ from one material to
another, and it can have different causing phenomena, the most harmful being
the air pollution, which along with the rain can produce several alteration
phenomena: the so-called “black crust”, material exfoliations and salt
efflorescence.
There have been made two X-ray Powder Diffraction analysis, on the
samples taken from the Art Museum in Cluj-Napoca, one on the black crust
(shows a high quantity of magnesium calcite, sulfates, and some quartz traces),
and one on the salts present on limestone (show a high quantity of thenardite,
and some quartz and calcium traces).
Keywords: air pollution, cultural heritage, acid rain, black crust,
