In this work, two analytical methodologies based on liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) were developed for quantification of emerging pollutants identified in sewage sludge after a previous wide-scope screening. The target list included 13 emerging contaminants (EC): thiabendazole, acesulfame, fenofibric acid, valsartan, irbesartan, salicylic acid, diclofenac, c...

in order to investigate the effect of municipal solid waste (msw) compost and sewage sludge (ss) on yield and concentration of heavy metals in soil and black cumin (nigella sativa l.) an experiment with msw compost at 0, 15, 30 t.ha-1 (c0, c15 and c30) and sewage sludge at 0, 15, 30 t.ha-1 (s0, s15 and s30) in a factorial experiment based on completely randomized design with three replications ...

Ž .Linear alkylbenzene sulphonates LAS are a group of anionic surfactants, characterised by having both ahydrophobic and a hydrophilic group. LAS is one of the major ingredients of synthetic detergents and surfactants andis used world-wide for both domestic and industrial applications. LAS is relatively rapidly aerobically degraded, butonly very slowly or not at all degraded und...

application of sewage sludge as a cheap and waste material is increasing for supporting plant essential elements especially in the soils of arid and semiarid regions. in the present greenhouse research, the effect of ardabil municipal sewage sludge on n, p, k, pb, cr, ni and cd concentrations in soil and plant and also spring wheat yield and growth indices was studied as a randomized complete b...

The conventional sludge disposal options include landfill, application to farmland and forestry and incineration. However, since in the last decade sewage sludge and industrial sludge are being generated in increasing amounts due to the rapid urbanization and industrialization, a growing interest has been devoted in developing cost effective and renewable disposal alternatives. Among them, the ...

different additives have been considered to improve stabilization of the engineering properties of fine-grained soil. the present study investigated the effect of the addition of sewage sludge ash on the compressive strength of clay soil at optimum moisture content and under saturated conditions. the four treatments tested were the addition of 0%, 5%, 10% and 15% sewage sludge ash to clayey soi...
