Określono w jakim stopniu proces dojrzewania kompostu otrzymanego z osadu ściekowego z dodatkiem trocin i popiołu lotnego, wpływa na zmianę zawartości wielopierścieniowych węglowodorów aromatycznych (WWA). W badaniach zastosowano kompost otrzymany z samego osadu ściekowego, osadu z dodatkiem trocin (20% w/w) oraz osadu z udziałem popiołu lotnego w ilości 20 i 30% w/w. Proces dojrzewania prowadzono...
The present study included an evaluation of the content of 16 PAH in sewage sludge produced in 15 sewage treatment plants in southeastern Poland. Besides determining PAH content, the influence of the amount and origin of the sewage purified in the PAH content was also evaluated. Possible PAH sources in sewage were also evaluated by the calculations of the mutual relations. The results obtained showed...
