Floating Plastic Media for Removal of Organic Pollutants in Agricutural Drainage Water
Agricultural drainage water (ADW) may be considered as a strategic reserve to cope with the everincreasing demand for water resources. However, the cost required for treating ADW harnesses its wider reuse. Thus, the current ambition is to continue developing cost-effective technologies and enable the best use of this secondary sustainable resource. This research presents a low-cost suspended ca...
متن کاملPersistent organic pollutants in plastic marine debris found on beaches in San Diego, California.
Plastic debris were collected from eight beaches around San Diego County, California. Debris collected include: pre-production pellets and post-consumer plastics including fragments, polystyrene (PS) foam, and rubber. A total of n = 2453 pieces were collected ranging from <5 mm to 50 mm in size. The plastic pieces were separated by type, location, and appearance and analyzed for polycyclic arom...
متن کاملCriteria air pollutants and toxic air pollutants.
This review presents a brief overview of the health effects and exposures of two criteria pollutants--ozone and particulate matter--and two toxic air pollutants--benzene and formaldehyde. These pollutants were selected from the six criteria pollutants and from the 189 toxic air pollutants on the basis of their prevalence in the United States, their physicochemical behavior, and the magnitude of...
متن کاملNew plastic joints for plastic orthoses.
Plastic joints for orthoses have more advantages than metal joints. They are lightweight, noiseless comfortable to use, rust proof, corrosion free, and radiolucent. Two types of plastic joints were developed by the authors, one for the ankle joint and the other for the knee joint, elbow joint or hip joint. Polypropylene was chosen as the joint material because of its appropriate flexibility and...
متن کاملPersistent Organic Pollutants ("POPs")
Strictly speaking, all toxins entering the environment can be regarded as environmental poisons. Certain pollutants can, acting over long periods, harm living organisms even in low concentrations. This means that pollutants that are stable and thus persistent have a great ability to act as environmental poisons. Their stability means not only that their effects are long-lasting, but also that t...
