Exposure of R fluitans to concentrations of PHEN equal to or greater than µ m PHEN caused a rapid increase in amino acid leakage with no recovery suggesting severe plasma membrane damage PHEN at concentrations of µ m or less caused a more gradual concentration dependent increase in amino acid leakage peaking 24 h after exposure A
The search in the aquatic part of the ECOTOX database was constrained to concentration based endpoints for individual effects of the 16 USEPA s priority PAHs CAS numbers given as entry in freshwater animal species crustaceans insects/spiders molluscs worms other invertebrates regarding growth mortality physiology and reproduction
Hydrocarbon contamination is of great worry because of their widespread effect on all forms of life Pollution caused by increasing the use of crude oil is ordinary because of its extensive application and its related transport and dumping problems Crude oil contains a complex mixture of aliphatic aromatic and heterocyclic compounds Soil naturally consists of
Organic pollutant contamination in the environment is a serious and dangerous issue especially for developing countries Among all organic pollutants polycyclic aromatic hydrocarbons PAHs are the more frequently discovered ones in the environment PAH contamination is caused chiefly by anthropogenic sources such as the disposal of residential
The polyaromatic hydrocarbons types concentrations and sources in particulate matter and aquatic plant in Tigris River Baghdad Iraq The maximum value of PAHs in the aquatic plant was 8 1μg kg dry weight of acenaphthylene in January 2018 while the most abundant compound
However the ability to predict the hydrocarbon concentrations that affect the condition of wetland plants is limited due to the wide range of chemical and species effect concentrations Most toxic effect levels for crude and refined oils applied to soil or foliage have been between 1 L/m 2 and 24 L/m 2 Table 6
The seasonal variation of petroleum pollution including n alkanes in surface sediments of the Selangor River in Malaysia during all four climatic seasons was investigated using GC MS The concentrations of n alkanes in the sediment samples did not significantly correlate with TOC r = p > The concentrations of the 29 n alkanes in the Selangor
In aquatic environments the PAHs concentrations range widely from ng/L seawater; Southeastern Japan Sea Japan to 8 310 000 ng/L Domestic Wastewater Treatment Plant Siloam South Africa Moreover bioaccumulation of ∑16PAHs in fish has been reported to range from ng/L Cynoscion guatucupa South Africa to ng/L
The severity depends on hydrocarbon type concentration and exposure duration requiring prompt medical microalgae such as Chlorella and Scenedesmus have the potential to absorb and metabolize hydrocarbons in aquatic Phytoremediation is an eco friendly method that utilizes plants to address hydrocarbon contamination by absorbing
The TPH concentrations of in the plant tissues and soil under the different treatments following remediation are shown in Fig S3 After 90 d of remediation g kg −1 TPH the residual TPH concentrations in the alfalfa plant and soil were g kg −1 and g kg −1 respectively According to the principle of quality conservation
The model considers oil spill effects on aquatic organisms including fish invertebrates aquatic plants plankton birds mammals and reptiles That is while the hydrocarbon concentrations in zooplankton for example change with prevailing conditions changes in overall zooplankton biomass are not modelled Another limitation was the
Petroleum hydrocarbon waste is a common contamination in several environmental mediums including soil water and air Petroleum hydrocarbons are often seen in many locations including refineries where they serve as feedstocks for processes such as plastic manufacturing as well as at facilities involved in the production of petrol and retail service
Purpose Plant species was considered to be a significant factor influencing the efficiency of phytoremediation Therefore the ability of four submerged aquatic plants to facilitate the remediation of sediments polluted with polycyclic aromatic hydrocarbons PAHs was compared Materials and methods Surface sediments top 0 15 cm were collected from the
Petroleum hydrocarbons emitted by industrial processes disrupt aquatic life and degrade ecosystems by accumulating inside food chains and causing living animals to produce toxic secretions
Rhizofiltration involves removing toxic substances using plant roots in a saturated zone to remediate aqueous contaminants from wastewater ground water or surface water through adsorption concentration and precipitation onto roots or other submerged organs of metal tolerant aquatic plants Jadia & Fulekar 2009 In this technique plant
This work presents an integrated overview of polycyclic aromatic hydrocarbons PAHs ubiquity comprising environmental contamination in the air aquatic ecosystems and soils; characterizes the contamination in biota; and identifies main biomonitors and human exposure to PAHs and associated health risks Urban centers and industrial areas present increased
The search in the aquatic part of the ECOTOX database was constrained to concentration based endpoints for individual effects of the 16 USEPA s priority PAHs CAS numbers given as entry in freshwater animal species crustaceans insects/spiders molluscs worms other invertebrates regarding growth mortality physiology and reproduction
Analysis revealed concentrations of 3000 41000 and 91000 mg⋅kg 1 of total petroleum hydrocarbon TPH in soil where the three individual plants of E erythropoda were sampled and concentrations of 280 380 and 9040 mg⋅kg 1 of TPH where the three individual pants of P balsamifera were sampled
Detection of polycyclic aromatic hydrocarbons compounds concentrations and their fate in Tigris River within Baghdad City Iraq January 2019 The Iraqi Journal of Agricultural Sciences 50 Special
Polycyclic aromatic hydrocarbons PAHs are genotoxic carcinogenic and persistent in the environment and are therefore of great concern in the environmental protection field Due to the inherent recalcitrance persistence and nonreactivity of PAHs they are difficult to remediate via traditional water treatment methods In recent years microbial remediation has
A higher petroleum hydrocarbon concentration has been reported toxic to crop plants and much other vegetation Soil aeration water infiltration clogged by oil may severely affect plant growths Hou et al 2021; Steliga and Kluk 2020 primarily reducing the root length and leaf area of sunflower crops Hou et al 2021; Steliga and Kluk 2020
Although resistant plants can degrade petroleum hydrocarbons and separate them from the soil environment various factors including pollutant behavior and concentration plant handling oxygen
To evaluate the pollution level and health risk of total petroleum hydrocarbon TPH seawater sediments and aquatic organisms were sampled from the southern sea area of Zhejiang Province Yangtze River Delta China between 2017 and 2019 TPH was widely present in the aquatic environment and products and its concentration was highly variable The
