The article deals with the problem of determining the influence of capacity on the presence of phthalates — esters of phthalic acid (EFC) and its isomeric compounds in the studied objects. The work is relevant in connection with the lack of clear rules for the transportation of objects that are provided for forensic research on the content of phthalates, because the packaging of objects in improperly selected packaging may lead to the EFC falling into the object under study and false as a whole research results.
The purpose of the work was to establish the presence of phthalates in the bottled drinking water, which is being sold in the territory of Ukraine in a polymeric container made of polyethylene terephthalate (PETF, PET), as well as tap water and distilled water and ethyl alcohol, placed in the same bottles during research. Establishing an EFC in facilities placed in PET packaging is a direct confirmation of existing experience with similar topics.
The determination of the content of the EFC was carried out by gas chromatography-mass spectrometry. It is shown that in the composition of any drinking water from those sold on the domestic market in PET packaging, there is an EFC. In this case, the sample of mineral water in glass containers, as well as distilled, tap water, ethyl alcohol used in this work, the EFC did Not contain within the limits of quantitative definition. After the expiry of these samples of distilled water and ethyl alcohol in the PET packaging, the presence of phthalates was detected.
The results of this work are supported by well-known global studies to determine the possibility of migration of the EFC from the packaging material to its liquid content. Taking into account the results obtained, we have provided recommendations for the packaging of liquid research objects when they are sent to a study to determine the content of the EFC.
