Abstract Organic micropollutants, in particular those of anthropogenic origin, may have a toxic influence on water organisms. Photochemical oxidation processes are one of the most effective methods of decomposition of a wide range of those compounds. During the oxidation process a large number of different by-products are generated, which can still be biologically active. The development of analytical techniques, including the reduction of the detection limit to several fg/L, allows the identification of even trace concentrations of compounds. The paper presents the determination of pentachlorophenol and benzo(a)pyrene degradation pathways during the process of heterogeneous photocatalysis carried out in the presence of titanium dioxide. The gas chromatography–mass spectrometry (GC-MS) analysis of post-processing samples indicated the formation of different by-products of the parent micropollutants. Moreover, the toxicity assessment demonstrates for both tested micropollutants an increase in the toxicity within the whole time of the UV irradiation process run.

Investigation to evaluate the toxicity of carbofuran pesticides on haematological parameters of third instar larvae of Oryctes rhinoceros L. Indicated alterations in total haemocyte count and differential haemocyte count for toxicity assessment. Various doses of carbofuran (0.05g, 0.010g and 0.015 g) applied on insect through oral route and its impact after 24 hours of its application revealed that various doses of carbofuran exert specific alterations in both total and differential haemocytes of insect haemolymph.
