The production and usage of polymeric materials nowadays is increasing, which also increases the amounts of waste. Sometimes the materials used in manufacturing polymeric materials are toxic; some of them are even cancerogenic or mutagenic. Different polymeric material additives are also dangerous to the human health, such as plasticizers, stabilizers and others. The increase in waste streams result in problems related to the waste recycling. Therefore with the development of industry and the increase in consumption of consumer products, it is important to evaluate the impact of daily available and used materials, in order to decrease the threats to human health and environment. The goal of the present Bachelor paper is to conduct a research on polymeric materials that are used on daily basis, namely, polystyrene, polycarbonate and polyvinyl chloride. For conducting the research the author selects three polymeric articles that are often used on daily basis in disposable plates, packaging, as well as in children’s dishes made by different manufacturers. The material of these articles is defined by using the express-method and Infrared Spectroscopy. The defined type of material is then compared with the labelling after that the author analyses the influence of the material on human health. During the process of research it is concluded that even though the labelling is an obligatory requirement, there are still many daily used products that do not have the labelling. Therefore the identification of material is made more difficult, which in turn is important for both consumers and waste manager in case the waste separation. By using a Scanning Electron Microscope with Energy Dispersive Spectroscopy the author defines the chemical element composition of polymeric materials; therefore it is possible to find the additives that are used in the selected articles. The additives then are additionally researched in order to find out the reasons of their usage in the article, as well as to understand how it will potentially influence the human health. The present paper provides conclusions about possible threats of available materials to the health of consumers, as well as characteristics of the behaviour of these materials in the whole waste stream. The duration of waste decomposition in the environment is over hundred years; therefore the total amount of waste is continuously increasing. It is necessary to reduce this tendency, however at present the ratio of polymeric material recycling is very low. One of the main solutions in the field of waste management would be the education of consumers and the decrease of total amount of polymeric material waste. These measures require time and investment, therefore one of the most frequently used solutions for this problem is waste incineration. This is the most inappropriate way of waste management, because uncontrolled incineration of waste material not only pollutes the environment, but also is dangerous to human health as the incineration process produces dangerous chemical compounds. The results of the present analysis proved that in Latvia it is possible to purchase dishes made of polymeric materials that are manufactured from melamine-phenol-formaldehide condensation product and polycarbonate bisphenol A. An improper usage of such dishes can be a serious threat to the child’s health. Therefore the Bachelor paper proves that the daily used dishes can be a potential threat to the human health.
