Depending on the origin, the compost produced may contain not only nutrients but also pollutants, such as heavy metals and persistent organic pollutants. It is very important to determine them in soil-improving substances, because persistent organic pollutants show environmental toxic, cancerogenic, mutagenic effects and do not decompose for a long time. The aim of this study was to determine seven polychlorinated biphenyls concentrations in different kinds of composts produced in Lithuania and to evaluate the appliance of these composts in agricultural land. First, before routine analysis was done a gas chromatography with electron-capture detector method was developed. In this study 145 samples of green waste, sewage sludge, cattle manure, food waste, mixed municipal waste, digestate and composts made from mixed municipal waste after mechanical–biological treatment were analysed. Obtained results show that 28% of investigated cattle manure composts (CMCs) and 10.5% of food waste composts (FWCs) were free from polychlorinated biphenyls. Other kinds of composts investigated in this study (green waste compost (GWC), sewage sludge compost (SSC), mixed municipal waste compost (MMWC), mixed municipal waste compost after mechanical biological treatment (MMWCABMT) and digestate (DIG)) were contaminated 100% with polychlorinated biphenyls. Despite the fact that polychlorinated biphenyls were forbidden 25 years ago, their concentration varied from 2.70 to 163.7 µg kg−1 in different kinds of composts produced in Lithuania. According to get an increasing average amount of Σ7 polychlorinated biphenyls, Lithuanian composts were distributed as follows CMC > GWC > DIG > FWC > SSC > MMWCABMT > MMWC.

The present study is an attempt to examine the effects of municipal waste and wastewater on absorption of nickel and cadmium of helianthus annuus plant. In order to determine cadmium and nickel in different organs of the plant in soil with organic fertilizers of municipal waste and municipal sewage sludge, we conducted a split plot study. The study was in form of randomized complete block from 2011 to 2015 under farm conditions. We considered the main factor in five levels of control, 10 and 20 tons of sewage sludge and municipal waste compost per hectare besides the minor factor of yearly treatment during four years. The results showed that using 20 tons of sewage sludge and waste per hectare increased absorbable soil nickel and cadmium up to approximately 220%. Also, the amount of cadmium and nickel in root was about 400% more than the control group. Bacteria found in soil contaminated to heavy metals showed remarkable resistance against higher concentration of these elements. Both bioaccumulation and biosorption techniques indicated high potential to refine aquatic environments. However, the bioaccumulation technique showed better efficiency in lower concentrations and the biosorption revealed better efficiency in higher concentrations of metals.

The aim of the research was to determine the effect of soil contamination with diesel oil (0; 5; 10 and 15 cm3 kg−1 of soil) on the content of trace elements in the aboveground parts of oat (Avena sativa L.). Stabilised sewage sludge was used to mitigate the likely negative impact of diesel oil on the plant. Growing soil contamination with diesel oil had a significant impact on the content of trace elements in the aboveground biomass of oat. In the series without sewage sludge, the contents of the analysed elements, except for chromium, zinc, copper and cobalt, were positively correlated with the increasing doses of diesel oil. The largest increase in the content was recorded in the case of manganese. The sewage sludge used to reduce the influence of diesel oil on the chemical composition of oat had a positive effect on the content of the analysed trace elements. Compared to the series without the addition of a stabilised sewage sludge, it contributed to a reduction in the average content of chromium, nickel, copper, manganese and cobalt in the aboveground parts of oat plants. No significant effect of the applied remediation treatment was noted for cadmium, and the results were equivocal for iron.
