Sažetak
Lot of evidence has been accumulated within the last 50 years that environmental pollution poses a threath to human and wildlife. Sewage, agricultural runoff and industrial wastewater are the main sources of water pollution and make it useless for drinking, recreation, agriculture and industry. Various harmful substances not only directly affect fish but are also accumulated in them. Consequently, different alterations are brought about in fish, ranging from biochemical through to those in the whole population. Fish health may thus reflect pollution of aquatic ecosystem. Histopathology is the study of alterations on the tissue level. Although fish may react speciffically to some harmful stimuli, in most cases the same response is elicited by different chemical substances and their mixtures. Though reports on the histological response in fish under laboratory conditions are numerous, reports on examinations of fish in the field are surprisingly rare. Most international drinking water quality guidelines include total coliforms as microbial indicator of water quality. Additionally, most guidelines refer to total estimates of bacterial number, generally termed total heterotrophic bacteria, being considered to represent the general cleanliness of water.
