Mikroplasty a jejich vliv na životní prostředí
Summary
This Czech bachelor's thesis reviewed microplastic pollution in the environment, focusing on sources, occurrence in water systems, and effects on living organisms and human health. A questionnaire survey of respondents revealed that while most were familiar with the term microplastics, many lacked detailed knowledge of their environmental impacts and over 80% supported refundable plastic bottle systems.
This bachelor thesis deals with plastic pollution in the environment predominantly focusing on microplastics. The aim of the theoretical part is to acquaint readers with the terminological background of plastics and their microscopic parts. This part also contains an overview of current information about sources, presence, and possible impact of microplastics in the environment centring on the water component. The theoretical part further discusses the effect of microplastics on living organisms and one’s health. In the practical part of the thesis, a questionnaire survey was carried out to find out respondents’ opinions and awareness of the given matter. The results of the survey confirmed that most of the respondents, despite being familiar with the term microplastics, are not well informed about their impact on the environment. The survey also indicates that this area lacks public awareness. Furthermore, a comparative analysis shows that more than 80% of the respondents would be in favour of refundable plastic bottles. Finally, the survey appears to confirm that respondents have poorer knowledge in legal regulations dealing with plastic waste.
