The task of biotechnology, environment and toxicology department
The department of biotechnology and toxicology is developing and putting into practice
environmental technologies directed at disposal of refinery waste and environmental air
protection. It is providing the determination of biological degradability of products and
evaluation of their toxic features.
Competence and main activities of biotechnology, environment and toxicology
development of technology for
the decontamination of soil contaminated by crude oil substances and implementation of the
technology
investigation and development of
polluted air purification by means of bio-filters
introducing of new testing
methods directed at biologic degradability of substances
development of new
eco-technologies on the basis of physical and chemical processes.
A. Laboratory tests
Determination of non-polar extractible substances by IR
spectroscopy
The method is based on crude oil substances extraction with non-polar solvent (Ledon
113). The co-extracted polar or semipolar sobstances are separated through adsorption on
silicagel and the extract is analyzed in the IR spectral range.
in waste water according to
DIN 3814, 4 vol., practically consistent to STN 83 0540 part 4
The method is suitable to determine concentrations of hydrocarbons - crude oil
substances above 0,1 mg/l.
in water extract - according
to DIN 3814, 4 vol., practically consistent to STN 83 0540, part 4
From the test materials the non-polar extractible substances that are soluble in water
are determined at exactly stated conditions. The method is applicable for solid materials,
with grain size maximum 1 cm3, pastes and sludges.
in soils according to STN 83
0540 part 4, modified by the Centre for evaluation of laboratory capability (ASLAB Prague)
in sludges according to STN
75 7952
in compost according to STN
75 7952, modified method
The method determines the main part of non-polar hydrocarbons in sludges, with a weight
fraction above 1g/kg in dry matter of sludge.
B. Special test methods
Gene mutation (Ames test - OECD 471)
The test is done to determine gene mutation caused by the studied substances on
bacterial strains of Salmonella typhimurium, with and without metabolic activation.
Chromosome mutation in vitro (Micro-nucleus test - OECD 474)
The test is for the detection of chromosome mutation caused through the effect of
studied substance, on lymphocytes of the peripheral human blood, with and without
metabolic activation.
DNA damage and repair (Reparation test - OECD 482)
The test serves for the detection of DNA damage and repair caused by the investigated
substance on bacterial strains of Escherichia coli with and without metabolic activation.
Biodegradability of products (according to method CEC L - 33 - A - 93)
The method states biologic degradability of various water insoluble crude oil products.
C. Other services
Advisory and consulting services in the area of:
decontamination of soil
contaminated by crude oil substances
composting of sludge and other
types of waste
polluted air purification with
biofilters
synthesis and modification of
diverse types of zeolites for the investigation of adsorptive and catalytic
characteristics and development of adsorption and catalytic processes
application of synthetic
zeolites (molecular sieves) in adsorption processes
synthesis and modification of
aluminium alcoholates for the production of lubricating greases and preparation of
high-purity aluminium oxides
removal of heavy metals from
waste water
applicable legislation to judge
the effect of chemical substances from the viewpoint of potential gene-toxic effects
elaboration of reports of
products´ health harmlessness
elaboration of literature
reviews of products´ health harmlessness
elaboration of required tests to
put products on the market.
