In 2015, it was calculated that 275 million tonnes (303 million short tons) of plastic waste was generated in 192 coastal countries in 2010, with 4.8 to 12.7 million tonnes (5.3 to 14 million short tons) entering the ocean – a percentage of only up to 5%. [19] Most land-based plastic pollution enters the ocean from South, Southeast, and East ...
Plastics accounts for 80% of waste dispersed in the marine and coastal environment of the Mediterranean Sea. [24] Recent studies focus on the types of plastics found and primarily on the issue of microplastics, both at a global but also at a regional level, as in the case of the Mediterranean Sea, which was identified as a "target hotspot of the world" due to its amounts of microplastics ...
Most coatings have four basic components. These are the resin, solvent, pigment and additive systems [5] but the resin or binder is the key ingredient. Continuing environmental legislation in many countries along with geopolitics such as oil production are ensuring that chemists are increasingly turning to waterborne technology for paint/coatings and since resins or binders are the most ...
The South Aral Sea, half of which lies in Uzbekistan, was abandoned to its fate. Most of Uzbekistan's part of the Aral Sea is completely shriveled up. Only excess water from the North Aral Sea is periodically allowed to flow into the largely dried-up South Aral Sea through a sluice in the dike. [77]
Low-VOC paint types include latex (water-based), recycled latex (water-based), acrylic, and milk paint. [1] [2] The labels of paint cans can be checked for the following information: To be considered low-VOC, the paint should contain <50 g/L of VOC. [citation needed] To be considered zero-VOC, the paint should contain <5 g/L of VOC. [citation ...
Debris on beach near Dar es Salaam, Tanzania Debris collected from beaches on Tern Island in the French Frigate Shoals over one month. Researchers classify debris as either land- or ocean-based; in 1991, the United Nations Joint Group of Experts on the Scientific Aspects of Marine Pollution estimated that up to 80% of the pollution was land-based, [5] with the remaining 20% originating from ...
[1] [2] As of 2022, an estimated 51 trillion microplastics are floating in the surface water of the world's oceans. [3] A single 5mm piece of plastic can host 1,000s of different microbial species. [4] Some marine bacteria can break down plastic polymers and use the carbon as a source of energy. Microbes interacting with the surface of plastics.
In industry, super-hydrophobic coatings are used in ultra-dry surface applications. The coating can be sprayed onto objects to make them waterproof. The spray is anti-corrosive and anti-icing; has cleaning capabilities; and can be used to protect circuits and grids. Superhydrophobic coatings have important applications in maritime industry ...
