Oysters exposed to polystyrene microplastics produced fewer offspring, which were also smaller and slower growing than offspring from unexposed oysters, according to recent research. The researchers say their study adds to growing evidence of the harm caused by microplastic pollution and can help stakeholders to take action on plastic debris entering the oceans to limit its long-term impact on marine life.

Fish fed polystyrene nanoparticles are less active and show changes to their brains and metabolism, according to a study by Swedish and Danish researchers. The findings suggest that nanoparticles in the environment could have a major impact on fish and aquatic ecosystems.

A process for preparation of 2-phenyl ethanol by catalytic hydrogenation of styrene oxide using a catalyst consisting of Pd (II) on basic inorganic support is investigated. The present invention comprises development of new Pd based catalysts. The present method yields 2-phenyl ethanol in 98% selectivity at total conversion of styrene oxide. The present process represents an environment friendly alternative to conventionally used methods in industry and eliminates the reduction step for catalyst preparation. In the present invention the active catalyst is generated in situ during the hydrogenation of styrene oxide. In addition, Pd (II) supported catalysts do not catch fire (non pyrophoric), can be stored under ambient conditions and produce very less or no dust which makes said catalysts suitable for industrial application.

The present invention relates to a method of manufacture of styrene-butadiene latexes. The styrene-butadiene latex according to the present invention is characterized by having a superior adhesive force as the formation of films at an early stage is promoted by adjusting the gel content and molecular weight of the outermost layer, as well as a fast ink-drying speed and a high air permeability as the formation of paper films is maintained. It may be applied to paper coating very stably since the mechanical stability and chemical stability of the latex are superior.

An electronic component packaging sheet formed of a styrene resin composition includes: (A) 29-65 mass parts of a styrene-conjugated diene block copolymer; (B) 51-15 mass parts of a polystyrene resin; and (C) 20-9 mass parts of an impact resistant polystyrene resin. Components (A)-(C) each have a weight average molecular weight (Mw) within a specified range.

Guleria said inhalation and ingestion of styrene can cause effect the skin and the eyes.

The central nervous system is affected by exposure to styrene smoke. It is the mucous membrane, which is primarily affected by styrene gas exposure. The styrene gas leak in Visakhapatnam triggered acute breathlessness among many men, some of whom were asphyxiated to death.

A new study has found the worms excrete plastic and its toxic additives with no residue in their bodies.

China has made a number of announcements on anti-dumping duty orders, including to launch an investigation into US, Korean, and Taiwanese exports of styrene, which is used to manufacture plastics and resins.
