In the higher organisms, the intake of trace elements occurs mainly through the respiratory system or through the food chain. Particularly, many dangerous elements or compounds, such as metals accumulate along the food chain. In this way, the food chain becomes the main gateway for persistent toxicants to enter higher organisms. Furthermore, these toxic elements generally have an anthropogenic origin and thus their concentrations in the environment grow with the increase of urban, agricultural and industrial emissions. With increasing environmental pollution, a toxic metal exposure assessment study is necessary. Toxic elements are not metabolized at all. Some metals irreversibly are bound to body tissues, e.g., lead to bone or cadmium to kidneys. This review updates the information on carry-over of toxic substances from feed to food of animal origin (meat, organs, milk and eggs). The control of environmental contaminants that may cause residues in food of animal origin is sometimes quite difficult and expensive and is addressed with special attention in this review.

Generally, the water quality depends on its chemical and microbiological conditions. So, in this study, the chemical and microbiological characteristics of the Perisuyu River through 4 year long surveillance in Tunceli. Turkey were studied. Sampling was carried out four times during the year. Nitrate, nitrite, ammonium concentrations, total dissolved solid, total coliform counts were determined and the presence of Escherichia coli, important water quality indicator, was tested. Generally in water samples E. coli and total coliform were found very high and nitrate, nitrite and ammonium concentrations were low. In 2008 August and 2009 February water pH was higher than the World Health Organization limit value. Electrical conductivity was higher in 2004 May, December and 2008 February.

Heavy metal pollution of waters is a major environmental problem. Due to their toxicity, long persistence, bioaccumulative and nonbiodegradable properties in the food chain, heavy metals constitute a core group of aquatic pollutants. Capoeta trutta is an economically important fish and the object of significant commercial fishery in the Munzur River. Levels of Cu were measured in samples of the muscle, gill and liver tissues of C. trutta from Munzur River. In liver copper levels were higher at Station I (6.15 mg kg(-1)) polluted by domestic waste than Station II (5.48 mg kg(-1)) (P<0.05). The highest copper level (7.25 mg kg(-1)) was measured in muscle tissue at Station II. There was found no statically differences between stations in gill and muscle (P>0.05). It is suggested that ecological condition of freshwater fish and contamination levels in Munzur River must be regularly monitored.

CIMEN, M., N. YILDIRIM, A. DIKICI, O. KAPLAN and N. CIKCIKOGLU YILDIRIM, 2010. Seasonal variations of biochemical taste parameters in milks from conventional and environment-friendly organic farming. Bulg. J. Agric. Sci., 16: 728-732 The aim of this study is to research the milk biochemical taste components in organic (ORG) and conventional (CON) systems for different season. In study, all data were investigated for all season of 2004. Milk fat levels in both groups for summer season were lower than any other season. Average milk fat values in ORG treatment were lower than the values of CON treatment in all season except winter period. Therefore, a decrease in fat percentage for organic milk can directly lead to taste loss. Similarly, total solid rates in conventional milks in spring period were more favorable than rates in organic milk for desired taste. However, the pH value in organic milk was more acceptable for required flavor in summer season.
