چکیده

Plastic materials are commonly used for storing food stuffs and medicines. Chemical substances used in the manufacture of plastic goods are found to migrate in the food stuffs used. The migration of UV absorbents and oxidisable matter was found to be more when used for longer periods.

Chemistry and toxicity of flame retardants for plastics.

An overview of commercially used flame retardants is give. The most used flame retardants are illustrated and the seven major markets, which use 96% of all flame-retarded polymers, are described. Annual flame retardant growth rate for each major market is also projected. Toxicity data are reviewed on only those compositions that are considered commercially significant today. This includes 18 co...

Migration of plasticizers phthalates, bisphenol A and alkylphenols from plastic containers and evaluation of risk.

This study investigates the potential migration of plasticisers, plastic components and additives from several plastic water bottles. Compounds studied were phthalates (dimethyl phthalate, di-n-butyl phthalate, benzylbutyl phthalate, bis(2-ethylhexyl) phthalate), bis(2-ethylhexyl) adipate, octylphenol, 4-nonylphenol and bisphenol A. Polycarbonate (PC), high-density polyethylene (HDPE), low-dens...

Accounting for Greenhouse Gas Emissions of Materials at the Urban Scale-Relating Existing Process Life Cycle Assessment Studies to Urban Material and Waste Composition

Although many cities are engaged in efforts to calculate and reduce their greenhouse gas (GHG) emissions, most are accounting for “scope one” emissions i.e., GHGs produced within urban boundaries (for example, following the protocol of the International Council for Local Environmental Initiatives). Cities should also account for the emissions associated with goods, services and materials consum...

Differential cellular metabolite alterations in HaCaT cells caused by exposure to the aryl hydrocarbon receptor-binding polycyclic aromatic hydrocarbons chrysene, benzo[a]pyrene and dibenzo[a,l]pyrene

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous in the human environment. Since they are present in crude oilfractions used for the production of rubber and plastics, consumers may come into direct dermal contacts with these compounds (e.g., via tool handles) on a daily basis. Some individual PAHs are identified as genotoxic mutagens thereby prompting particular toxicological and environ...

Comparative study on cardiotoxic effect of Tinuvin 770: a light stabilizer of medical plastics in rat model.

Tinuvin 770 [bis(2,2,6,6-tetramethyl-4-piperidinyl) sebacate], is a UV light stabilizer plastic additive used worldwide. It is a component of many plastic materials used in medical and food industries. Earlier studies demonstrated its in vitro L-type Ca2+ channel and nicotinic acetylcholine receptor blocking properties. Our previous experiments have proved the toxic effects of Tinuvin 770 on is...
