During the last decades, Polycyclic Aromatic Hydrocarbons (PAHs) are detected in agricultural soils and water bodies at concentrations higher than permitted limits. The main sources of PAHs are fossil fuels, biomass burning, waste incineration, and pesticides. They harm aquatic ecosystems and organisms and pose a high risk to human health. For these reasons, several laws have been enacted to regulate the permitted concentration levels of PAHs in the environment and specifically, the wastewater discharged into aquatic ecosystems. Several methods for the removal of PAHs from wastewater exist which, although efficient, are not used extensively due to their high installation and operation cost. Constructed Wetlands (CWs) constitute an effective, practical, and low-cost option for PAHs removal from polluted waters. This paper focuses on the various treatment processes for the removal of PAHs. Research findings indicated that vertical flow CWs and hybrid systems are more effective in removing PAHs.

Luminescent solar concentrators (LSCÃ¢â‚¬â„¢s) are evolving cost-effective organic methods for trapping solar energy using the fluorescence property of organic dyes. The study aims in finding a waveguide design for LSC, in different waveguide materials, PC and PMMA in varying dimensions filled with solution of anthracene in heptane with minimum losses. By comparing the output responses, the LSC with the waveguide design of 6 cm x 3cm x 5cm made of the PMMA (3mm thick) is observed to trap more incident radiation than the unaided solar cells. The maximum output current is measured to be 6.10 mA for a source of 40W power which is convincingly higher than 3.21 mA obtained from the unaided solar cell measured with the same source.
