In recent years, the widespread of microplastics in the food chain and environment became a topic of much research. This article focused on the knowledge and awareness of people with higher education levels&mdash:mostly young ones. The aim of this study is to analyze to what extent consumers know about and are aware of the source of microplastics, the level of exposure, and potential health hazards connected to the contamination of food and water with microplastics. The test group, consisting of 410 people, is mostly able to correctly characterize what microplastics mean and knows its sources. A majority of the group is aware of potential presence of microplastics in water: however, the knowledge about contamination of other elements of the environment seems to be gradually lowering. The majority of the people taking part in the research know that microplastic might be present in foods, and they are aware that after entering the human body, it might accumulate in internal organs. Moreover, when asked about potential health hazards, the group chose mostly tumors and gastrointestinal disorders, while disorders of the reproductive system were chosen less frequently. Consumers&rsquo: knowledge regarding the sources and health hazards of microplastics seems to be more common among women, in groups living in cities and among people who studied physics-related subjects and medicine.

BACKGROUND: Poor quality irrigation water is a major cause of disease transmission for urban inhabitants consuming fresh produce in many developing countries. Irradiation of food is an alternative approach to reducing health risks for consumers, but its implementation depends heavily on consumer acceptance.RESULTS: In this pilot study, we show that most respondents consider the water quality of Mexico City to be poor and a health risk, and would be willing to pay for irradiated food as a means of pasteurizing fresh iceberg lettuce.CONCLUSION: Irradiated food could, potentially, be accepted in developing countries that have problems with water quality. Such acceptance would presumably be due to the perception that such a novel technology would (1) alleviate water impairment, and (2) lead to economic improvement. It is then possible that the public considers that water quality is a more pressing concern than any potential side effects of food irradiation.

Agriculture is the largest human use of water. Clearly, agricultural practices need to be targeted to reduce wastage of water. This has been the centre of attention for water saving practices for some years. But there are additional ways to save water. Food consumers and businesses have a key role. This paper discusses the current problems of food demand and water scarcity and outlines some possible solutions to these issues. <br /><br />The amount of food produced on farmers&rsquo; fields is much more than is necessary for a healthy, productive and active life for the global population. Losses and wastage may be in the order of 50 percent between field and fork. Inefficient harvesting, transport, storage and packaging make a considerable dent in the potential availability of food. The situation now is characterised by rapidly increasing prices on food with dramatic repercussions for the poor, rates of inflation and, generally, for the stability of society.<br /><br />The authors recommend a range of actions. These include: <br /> support to farmers - actions are needed to support farmers, especially small farmers, to curb losses of water and food and to facilitate that their produce meets the growing demands for food through: improved seeds, harvesting technologies and storage and innovative ways to capture and beneficially use the rain water to lessen stresses on rivers and groundwater<br /> improve food processing and supply - the business community should take action to minimize water wastage through reducing food wastage in their processing and transport by: benchmarking standards to indicate water use; taking action to minimize wastage in their processing and transport systems; and raising publicity about their water use<br /> sensitise consumers - raise awareness amongst consumers about the water implications of their diets, overeating and food wastage through incentives, practical guidance and well designed campaigns<br /> disseminate basic data and information &ndash; there is a lack factual information about different types, size and implications of losses and wastage of food. An important step is therefore to improve knowledge.
