Pre Treatment

Polychlorinated substances, polyaromatic hydrocarbons, heavy metals and pesticides are among the priority even at low concentrations. The problem, however, is that such low concentrations are impossible to measure using most available methods. This researchfocused on the determination of selected priority substances – heavy metals, namely lead and cadmium, in which the determination ofPb and Cd in wastewater by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) was preceded by water sample pre-treatment.The paper deals with the influence of the pre-treatment on the resulting measured values. Two processes were selected as pre-treatmentprocesses. The first pre-treatment procedure was a simple filtration using a filter paper for moderate filtration. As the second procedure, we applied decomposition of the sample by nitric acid in the open system. The pre-treated wastewater samples were subsequentlyexamined using ICP-MS. Based on the obtained results, we can conclude that decomposition of the sample by nitric acid in the opensystem is a more suitable pre-treatment method for water samples

Automobile-service-station wastes make for an acute environmental concern because they contain polyaromatic hydrocarbons, heavy metals, surfactants, and other harmful elements. An eco-friendly way to treat and take advantage of these wastes is embodied in the concept called "valorization". In the present work, valorization is described as a chemical process to remove solids from contaminated water and to stabilize oily sludge into a saponified product. Electrocoagulation and coagulation with aluminum were applied to separate oil-water emulsions and removed 99.7% of turbidity. Both coagulation processes obtained approximately 0.85 kg of treated water and 0.027 kg of dried oily sludge per kg of wastewater. A saponification process with dosages of 10% NaOH stabilized the dried oily sludge. In hopes of finding pathways to valorize wastes, chemical treatments with aluminum and NaOH obtained a product that can be used as a surfactant or as an energy source.Keywords: sludge, electrocoagulation, saponification, oil, wastewater

Combined Contamination

The environmental contamination by heavy metals (HM) and polycyclic aromatic hydrocarbons (PAH) is often due to exposure to complex sources of industrial and agricultural activities. The aim of the work is to evaluate the combined effect of CuO and benzo(a)pyrene (BaP) on the state of spring barley plants. It was established that the soil combined pollution by CuO and BaP has a negative effect on all morphobiometric parameters of barley. The most sensitive indicators of combined contamination are the length of the roots, the mass of 1000 grains and the yield of barley.
