Accumulation of harmful substances from contaminated water in the food chain

U ovom radu prikazan je utjecaj onečišćujućih tvari iz otpadne vode na okoliš općenito, a posebno na živi svijet te zdravlje ljudi. Čovjek svojim načinom života upotrebljava resurse iz okoliša i time im mijenja kvalitetu, ne razmišljajući uvijek kako to ponovo može utjecati na njega. To posebno vrijedi za vodu koja je jako rasprostranjena, bez koje nema života, a ujedno je i najosjetljiviji resurs. Onečišćenje i zaštita vode su važan problem inženjerstva okoliša. U radu je posebna pažnja posvećena akumulaciji štetnih tvari iz vode kroz lanac prehrane u prirodi te je objašnjeno kako i kojim putem štetne tvari dolaze natrag do čovjeka.This paper presents the impact of contaminants from waste water on the environment in general, and especially on wildlife and human health. People use natural resources from their environment and change their quality with their way of living without thinking how this could in turn affect them.. This especially refers to water since it is widespread and there is no life without it, and also because it is the most delicate resource. Water pollution and protection is an important problem that environmental engineering deals with. The paper particularly pays attention to the accumulation of harmful substances from water through the food chain in nature and explains how these substances eventually find their way back to people
