This paper examines the effect of per capita income, trade openness, energy consumption, and financial development on the ASEAN region's environmental degradation. We obtained data from the World Development Indicators (WDI) during the years 2001-2020 to test our research model. For analysis, we applied panel data techniques such as pooled least squares, fixed effects, generalized least squares (GLS), and two stages least squares (2SLS). We also conducted the causality analysis to determine the direction of the relationship among the models' variables. Our models' results show the validity of the environmental Kuznets curve (EKC) hypothesis in the ASEAN region as per capita income and its square term possess positive and negative coefficients. The results also show the presence of an N-shaped EKC in ASEAN region a deviation from the conventional literature. Moreover, the results illustrate that increasing energy consumption, trade openness, and financial development positively contribute to environmental degradation in ASEAN economies. The causality analysis shows a two-way causality between trade openness and financial development, and environmental degradation and trade openness. We observed oneway causality, running a) from energy consumption and per capita income towards financial development, b) from per capita income towards trade openness, and c) from financial development towards environmental degradation. The study's results contribute to the environmental degradation literature and provide a better understanding of environmental degradation for policymakers in ASEAN economies.

Silver (Ag) and titanium dioxide (TiO) nanoparticles (NPs) are released into aquatic environments through wastewater treatment plants (WWTPs). Even though these NPs are mostly retained in WWTPs, a small fraction can be found in released effluents and may exert toxic effects on aquatic biota. Currently, the available information about the sublethal effects of wastewater-borne NPs on aquatic organisms is inconclusive and the importance of exposure media remains poorly understood.

Pharmaceutical Active Compounds (PhACs) are of particular interest among the emerging contaminants detected in the aquatic environment. Commonly, PhACs exist as complex mixtures in aquatic systems, causing potential adverse effects to the environment and human health than those of individual compounds. Based on the increasing interest in the contamination of water resources by PhACs, the photocatalytic degradation of Cimetidine and Amisulpride as a mixture in combination with their toxic and genotoxic effects before and after the treatment were evaluated for the first time.

Fludioxonil is widely used in the control of crop diseases because of its broad spectrum and high activity, but its presence is now common in waterways proximate to treated areas. This study examined the toxic effects and mechanisms of fludioxonil on the microalgal taxa Chlorella vulgaris. The results showed that fludioxonil limited the growth of C. Read More

Department of Comparative Biomedicine and Food Science, University of Padova, Viale dell'Università 16, 35020 Legnaro, PD, Italy.

Amyl salicylate (AS) is a fragrance massively used as a personal care product (PCP) and following the discharged in wastewaters may end up in the aquatic environment representing a potential threat for the ecosystem and living organisms. AS was recently detected in water of the Venice Lagoon, a vulnerable area continuously subjected to the income of anthropogenic chemicals. The lagoon is a relevant area for mollusc farming, including the Mediterranean mussels (Mytilus galloprovincialis) having an important economic and ecological role. Read More
