Bis(2-ethylhexyl) phthalate (diethylhexyl phthalate, diethylhexyl phthalate, DEHP; dioctyl phthalate, DOP) is an organic compound with the formula C 6 H 4 (CO 2 C 8 H 17) is the most common member of the class of phthalates, which are used as is the diester of phthalic acid and the branched-chain colorless viscous liquid is soluble in Chemical formula: C₂₄H₃₈O₄. Bioaccumulation of Phtalate Esters in Aquatic Food-Webs. The Handbook of Environmental Chemistry Vol. 3 Part Q: Underlying data regarding inherent toxicity to aquatic organisms.

The marine environment is directly linked to human life. Healthy oceans have always been important to mankind as all life depends on them. Nowadays, marine litter, mainly plastic, is found widespread in the environment, in all sea compartments, posing one of the major threats for the marine environment.

Aquatic Therapy: The Benefits of an Aquatic Environment Over the past several years aquatic therapy has increasingly made its presence in the field of physical therapy. This type of therapy, which was once regarded with some concerns, is now offering more certifications in an attempt to increase its credibility. degradable chemical pollutant in the aquatic environment (Mance, ). Toxicity testing is an essential tool for accessing the action and fate of toxicants in aquatic ecosystems. It is also necessary to derive the water quality standards for chemicals and to identify suitable organisms as bio Size: KB.

Phthalate esters are an important class of chemicals widely used in commercial applications, primarily as plasticizers to soften vinyl, but they are also used in consumer products.

This book reviews the state of the scientific knowledge of phthalate esters in the environment. Key information reported includes: analytical methodologies; a compilation of concentration. This book reviews the state of the science of phthalate esters in the environment.

Key information reviewed includes analytical methodologies, a compilation of concentration measurements in water, sediment, soil, air, dust, and food, plus an assessment of critical exposure pathways. While data from detailed studies of the mode of action of phthalate esters in aquatic organisms are lacking, polar narcosis is generally accepted as the primary mode of action [].Polar narcosis or type II narcosis is a general term used widely in the structure-activity (QSAR) literature to describe a group of organic chemicals that do not appear to act by a specific mode.

Get this from a library. Series anthropogenic compounds: phtalate esters. [Charles A Staples;] -- Phthalate esters are an important class of chemicals widely used in commercial applications, primarily as plasticizers to soften vinyl, but are also used in consumer products.

This book. A comprehensive and critical review was performed on the environmental fate of eighteen commercial phthalate esters with alkyl chains ranging from 1 to 13 carbons. A synthesis of the extensive literature data on physicochemical properties, partitioning behavior, abiotic and biotic transformations and bioaccumulation processes of these chemicals Cited by: Phthalates (US: / ˈ θ æ l eɪ t s /, UK: / ˈ θ ɑː l eɪ t s /), or phthalate esters, are esters of phthalic are mainly used as plasticizers, i.e., substances added to plastics to increase their flexibility, transparency, durability, and longevity.

They are used primarily to soften polyvinyl chloride (PVC). Lower-molecular-weight phthalates, those derived from C3-C6. Aquatic Pollutants: Transformation and Biological Effects contains the proceedings of the Second International Symposium on Aquatic Pollutants held at Noordwijkerhout (Amsterdam), The Netherlands on SeptemberOrganized into 47 chapters, this book first describes the aquatic pollutants and their potential biological effects.

Determination of phthalate esters in the aquatic environment Article in South African journal of chemistry. Suid-Afrikaanse tydskrif vir chemie June with 30 Reads. Urbanization has increased the discharge of phthalate esters to atmospheric and aquatic environments, and the use of agricultural plastics has exacerbated soil contamination by phthalate esters in rural areas.

Aerobic biodegradation is the primary manner of phthalate ester mineralization in the environment, and this process has been widely by: Aquatic toxicity of eighteen phthalate esters Article (PDF Available) in Environmental Toxicology and Chemistry 16(5) - May with Reads How we measure 'reads'.

This book reviews the state of the science of phthalate esters in the environment. Key information reviewed includes analytical methodologies, a compilation of concentration measurements in water, sediment, soil, air, dust, and food, plus an assessment of critical exposure : Charles Staples.

Phthalate esters with alkyl chain lengths of six carbon atoms or more were not acutely toxic at concentrations approaching their respective aqueous solubilities.

Insufficient mortality occurred to calculate either LC50 or EC50 values or acute no‐observed‐effect concentrations for these higher‐molecular‐weight phthalate by: aquatic environment.

For example, let us consider the floating ice bergs in the Antarctic Ocean. When heated by the solar energy, water temperature would increase due to the absorption of heat energy, if there was no ice.

Screening-level ecological risk assessments of di(2-ethylhexyl)phthalate (DEHP) for aquatic organisms in Japan were conducted using estimated statistical values based on surface water and sediment monitoring data and effect threshold values based on a large aquatic toxicity database.

Di-n-octyl phthalate appears as a clear liquid with a mild odor. Slightly less dense than water and insoluble in water. Hence floats on water. Flash point °F.

The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. As a liquid, can easily penetrate the soil and contaminate. Solubility values for eight phthalate esters investigated ranged from to mg/L.

Acute toxicity tests were conducted with fathead minnows (Pimephales promelas) and all eight phthalate and chronic tests were conducted with rainbow trout (Oncorhynchus mykiss) and Japanese medaka (Oryzias latipes) using di‐2‐ by: [More] Phthalate esters (PAEs), one class of the most frequently detected endocrine-disrupting chemicals (EDCs) in marine environment, have aroused wide public concerns because of their carcinogenicity, teratogenicity, and mutagenicity.

However, the environmental fate of PAEs in the occurrence of harmful algal blooms remains unclear. This book is a result of the course on environmental microbiology that I taught at the University of Northern Iowa, Cedar Falls, Iowa, USA.
