Abstract
The study presents initial findings regarding the occurrence and ecological risk assessment of organochlorine pesticides (OCP), polychlorinated biphenyls (PCB) and polycyclic aromatic hydrocarbons (PAH) in the Neretva Delta sediments, including 28 potentially toxic elements (PTEs) considering limited element studies. Parameters such as solvent type, temperature and number of extraction cycles were optimized for the accelerated solvent extraction (ASE) of PAH from brackish sediment samples. Mixture of cyclohexene: toluene (3:7, v/v) and four extraction cycles at 125 °C provide efficient extraction with recoveries ranged from 86 to 115% and relative standard deviation lower than 19%. Based on the proposed sediment and environmental quality screening standards, levels at all sampling sites may be considered as rare (PCB, OCP) or occasional (certain PAH) risk to aquatic life. The sediment-associated levels generally decreased in the order of contaminant groups: PAH > > PCB > OCP. The 28 PTEs decreased in the following order: Ca > Mg > Al > Fe > S > K > Si > Na > P > Ti > Mn > Sr > Zn > Sb > Cr > Ba > B > Ga > V > Cu > Pb > Li > Ni > As > Mo > Sn > Cd > Be. Specifically, elevated levels of As, Cd, and Mo suggest potential environmental risks, warranting further detailed monitoring and assessment.
期刊介绍：
Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments.
Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation.
Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
