Abstract

Due to its nutrient content, municipal sewage sludge can be well utilized in agriculture and crop cultivation. Despite this, domestic agriculture only uses it to a small extent, which is partly explained by its infectiousness and its toxic substances content. In the course of our investigations, we examined the potentially toxic element content, which is considered to be the most dangerous component of municipal sewage sludge. Our results show that if sewage sludge is disposed of in accordance with the legislation (quantity and quality compliance), even when examining the most unfavourable conditions, the harmful accumulation of heavy metals no need to count on. Based on all of this, the agricultural utilization of municipal sewage sludge with due care seems to be a beneficial solution, although in order to clarify this, it is now necessary to determine the amount of other micropollutants in it.
