Laboratory tests for nitrogen-containing compounds (nitrates, nitrites, ammonium)

Surface water contains a certain amount of nitrogen-containing compounds, which can be in different states: colloidal, dissolved and suspended. Under certain physical, chemical and biological environmental factors, these substances can pass from one aggregate state to another.

Nitrogen-containing compounds are the most important biogenic elements that are necessary for the functioning of living organisms.

The sources of these elements can be both natural and anthropogenic. As a rule, the largest input of these elements is from anthropogenic sources.

Excessive input of nitrogen-containing compounds can lead to contamination of the water body, and start the process of eutrophication.

The toxicological effects of these types of compounds are very diverse. Nitrites are the most dangerous compounds. If ingested, they can cause not only toxic, but also carcinogenic effects. Nitrates themselves do not have a toxic effect on the human body, but they can easily be transformed into nitrites. Nitrites can transform into more toxic forms: amines and nitrosamines, which cause cancer.

Laboratory analysis of nitrogen-containing compounds is a time-consuming process that requires accuracy and precision from a specialist. Also, during this analysis, reagents of good quality should be used, since the quality of the reagents significantly affects the result of the analysis.

Our laboratory is accredited for laboratory research (analysis) of nitrogen-containing compounds (nitrates, nitrites and ammonium) in drinking, surface natural (including marine), wastewater, and atmospheric precipitation.

In our laboratory, photometric and chromatographic analysis methods are used to determine nitrogen-containing compounds (nitrites, nitrates and ammonium ion), using new modern equipment (spectrophotometers, ion chromatographs), which guarantee a high-quality result.

Laboratory tests of PCTs and PCBs

Polychlorinated biphenyls (PCBs) are highly toxic persistent organic environmental pollutants.
The use of these compounds as dielectrics in condensers and coolers in heat exchange systems is a notable technological achievement of industrial chemistry in the mid-twentieth century.

Laboratory tests of dioxins (PCDD) and furans (PCDF)

Dioxins and dioxin-like compounds are recognized "leaders" in toxicity even among the chemical pollutants of the "dirty dozen"("грязная дюжина").
The most famous representative of this group of compounds is 2,3,7,8-tetrachlorodibenzodioxin, which has the maximum toxicity and is often referred to as dioxin proper.

Laboratory studies of the micro-plastic

Any particles of a polymeric material (plastic) having a diameter of less than 5 cm, regardless of their composition and origin, are classified as microplastics. Microplastic can be a direct product of industrial production: plastic powders and granules are often included in household chemicals and other chemical products. In other cases microplastic appears in the environment during the destruction of larger "macroscopic" objects.
