Composting of materials contaminated by micropollutants

Micropollutants are compounds of anthropogenic origin, detected at concentrations of ng·g-1 - mg·g-1 in the environment. Micropollutants are synthetic or natural compounds. Micropollutants are released into the environment due to various human activities. Despite low concentrations in the environment, they represent a real threat to organisms, because of their specific biological effects. Sewage sludge is used in agriculture due to its hight nutritious content. Via using sludge in agriculture, contained micropollutants can be released to environment. Composting is a cheap bioremediation method, used from 80's of the last century. This diploma thesis is focused on composting of sewage sludge, contamined with micropollutants. High degradation rate was observed in artificially contaminated sludge, mainly with endocrine disruptors (up to 100 %). Lower degradation rate was observed in sewage sludge from a pharmaceutical plant, some of the compounds were not degraded at all
