The concentrations of heavy metals (Cd, Cu, Fe, Ni, Pb, Zn) were measured in water, and fish samples caught from the pond at Fishery Park in Unicoi County, TN. The water samples were collected once a week for 8 weeks. The amounts of metals in the muscle tissues, gill, and liver of the two fish species were measured. This was to determine if any correlation exists between the metal contents in water and those in the fish samples. The concentration ranges for the heavy metals found in the water samples are as follows: Zn 0.04-0.13; Cu, 0.00-0.00; Pb, 0.00-0.59; Cd, 0.0067-0.0071; Fe, 0.208-0.512; and Ni, 0.044-0.270 ppm. The concentration range for the heavy metals found in the fish tissues are as follows: Zn 0.0-0.48; Cu, 0.00-0.00; Pb, 0.00-0.43; Cd, 0.00-99.7; Fe, 25.7-1245.5; and Ni, 0.00-268.5 ppm. There was a strong correlation found between the water and fish tissue samples.

Commercially available organic and conventionally grown vegetables were studied by quantitative determination of selected metals in them and to determine if any differences found are statistically significant. These findings can help the consumers to determine if the vegetable products are within the recommended maximum limits as proposed by the joint FAO/WHO Expert committee on organic foods designation. Eight edible vegetables were purchased from local stores in both the organic and conventionally grown categories. Samples were digested with concentrated nitric acid and the metals monitored were zinc, copper, lead, iron, cadmium, and nickel using flame atomic absorption. The concentration range for the heavy metals found are as follows: Zn, 2.04-69.4; Cu, 0.35-15.1; Pb, 0.00-3.99; Cd, 0.00-0.74; Fe, 2.52-319; and Ni, 39.9-53.8 μg/g. It was found that in general, conventional vegetables contain higher amounts of most of the heavy metals studied as compared to their organic counterparts. The study also showed that all vegetables products contain below the permissible limits for Zn, Cu, Ni, and Fe. For Pb all vegetables exceeded the safe limit except organic cucumber and conventional cabbage. For Cd, organic lettuce and green pepper, and conventional leafy green, green pepper, and spinach all exceeded the limit recommended by FAO/WHO.

Abstract Understanding and attitudes of the public towards the current Health Care Reform This thesis summarizes the basic facts about the current reform within the Health Care Sector and how it is being perceived by the general public. The theoretical part focuses on the basic information about the development of the Health Care Sector in the Czech Republic and its current reform. The development of the Health Care Sector from the year of 1918 until present is highlighted. At the beginning of the last decade of the 20th century, a new set of laws were passed, which triggered the initial reform of the Czech Health Care Sector. However, a period of passivity regarding subsequent legislation has resulted in the present problems. Further, there is a focus on current Health Care Reform enquiring: why the reform is needed, the nature of its stages and its legislative and non-legislative changes. Only a small part of the reform measures came into force. This included the introduction of regulation fees, the introduction of an `annual safe limit{\crq}, and the pricing and payment for medication. The practical part presents the research findings in relation to the issues mentioned above. The research part of the thesis, carried out using questionnaires, is concerned with the views of the public with respect to current Health Care Reform and investigates whether it has been understood by the public. The research shows that most of the respondents disagree with the reform and think that it is not developing in the right direction. The majority of respondents with this view were found to be within the age group of 60 and over, and within the group of respondents with a basic level or vocational education. Further, the research suggests that the public is not adequately informed about the new Health Care Reform, and therefore demonstrates a lack of understanding of its nature. In addition, the current political climate suggests that the public may lose interest in these issues and will become disengaged with the reform without further consideration.
