Biodegradable polymers and environmental interaction
Polymer Engineering & Science, 1998AbstractBiodegradable polymers are by definition those that degrade as a result of the action of microorganisms and/or enzymes. The rate of this biodegradation may vary from hours to years depending on the molecular architecture of the polymer in question.

Classification, Source, and Effect of Environmental Pollutants and Their Biodegradation
Journal of Environmental Pathology, Toxicology and Oncology, 2017Any foreign chemical substance that is unusually present within an organism or is unexpectedly found in the environment at a higher concentration than the permissible limits can be termed a xenobiotic or a pollutant. Such substances include carcinogens, drugs, food additives, hydrocarbons, dioxins, polychlorinated biphenyls, pesticides or even some ...

Biodegradation of chemicals in a standardized test and in environmental conditions
Chemosphere, 2003The estimation of biodegradation rates is an important source of uncertainty in chemical risk assessment. The existing OECD tests for ready biodegradability have been developed to devise screening methods to determine whether a chemical is potentially easily biodegradable, rather than to predict the actual rate, of biodegradation in the environment ...

Phenylmercuric acetate biodegradation by environmental strains of pseudomonas species
Research in Microbiology, 1989Organomercurial pollution occurring in the Rhine river in 1986 led us to study the possibility of depollution by mercury-resistant environmental aquatic strains. Four species of Pseudomonas were investigated for their ability to biotransform phenylmercuric acetate (PMA). Such biological depollution was demonstrated to be due to an enzymatic activity in

Biodegradability of polymers in environmental
2016With increasing global consumption and their natural resistance to degradation, plastic materials and their accumulation in the environment is of increasing concern. Approximately 140 million tonnes of synthetic polymers are produced worldwide each year.

Biodegradation of Environmental Pollution through Microorganisms
2020One of the best ways to eliminate environmental pollutions is biodegradation using microorganisms and plants. Biotechnology is key science and technology that is rapidly examining and developing in various environmental fields. Environmental biotechnology, in fact, allows to help preserve and develop the environment by utilizing the potential of plant ...

Environmental Impacts of Biobased/Biodegradable Packaging
Starch - Stärke, 2001The potential global and regional as well as the local environmental effects of the biological treatment of biodegradable polymeric materials are described in this paper. The global effects could be summarised as a decreasing contribution of methane release into the atmosphere by controlled biological treatment of waste and in a reduction of pollution ...

An environmental perspective on the biodegradation of organochlorine xenobiotics
International Biodeterioration & Biodegradation, 1996Organochlorine compounds have attracted interest since the discovery of chloroform as an anaesthetic, chloral hydrate as a sedative and more recently DDT as an insecticide. The value of many industrial products such as PCBs depends on their chemical stability, and many compounds including agrochemicals contain chlorine.

Assessment of Environmental Biodegradation of Synthetic Polymers
Journal of Macromolecular Science, Part C: Polymer Reviews, 1994The large-scale commercial use of synthetic polymers and their disposal in the environment is a phenomenon less than half a century old, a duration which is minuscule in the evolutionary time scale...

Directions for environmentally biodegradable polymer research
Accounts of Chemical Research, 1993A major factor promoting interest in biodegradable polymers is the growing concern raised by the recalcitrance and unknown environmental fate of many of the currently used synthetic polymers. These polymers include both water-soluble and water-insoluble types.
