British Culex pipiens complex [Culex pipiens sensu lato) mosquito distribution, abundance, and potential for disease transmission are intimately linked to their environment. Pond and lake dyes that block light to restrict algal photosynthesis are a relatively new product assumed to be an environmentally friendly since they are based on food dyes. Their use in urban garden ponds raises questions...

Tartrazine is an azo dye that widely used in the food and pharmaceutical industry. It also known to have a potential impact on human health. Reports indicate possible carcinogenic mutagenic effects of dye. Joint expert WHO/ FAO committee additives, Codex Alimentarius Commission (CAC) defined permissible limits for use tartrazine fermented products, including probiotic drinks, yet finds wide usa...

The synthetic food dyes studied were rose bengal (RB), phroxine (PL), amaranth, erythrosine B (ET), allura red, new coccine, acid red (AR), tartrazine, sunset yellow FCF, brilliant blue FCF, and indigo carmine. First, data confirmed that these dyes were not substrates for CYP2A6, UGT1A6, and UGT2B7. ET inhibited UGT1A6 (glucuronidation of p-nitrophenol) and UGT2B7 (glucuronidation of androstero...

Reliable exposure factors are essential to determine health risks posed by chemicals in consumer products. We analyzed five risk-concerned product categories (anti-fogging, dye, disinfectant, repellent, and preservative products) for 13 products (three car anti-fogging products, a lens anti-fogging product, two car dye products, two drain disinfectants, an air conditioner disinfectant, a chlori...

The clinical diagnosis of hypersensitivity to the food dye tartrazine in 16 subjects correlated with levels of tartrazine-specific IgD antibodies determined by a solid phase radioimmunoassay inhibition test. This is the first study associating hypersensitivity to a low molecular weight chemical with an antibody response of the IgD class. There was little or no correlation between clinical sensi...

water plays a vital and essential role in our ecosystem. this natural resource is becoming scarce, making its availability a major social and economic concern. use of a large variety of synthetic dyes in textile industries has raised an hazardous environmental alert. about 17 - 20% of freshwater pollution is caused by textile effluents. these effluents are recalcitrant to biodegradation and cau...

BACKGROUND Dyes derived from plants have an extensive history of use for coloring food and clothing in Dong communities and other indigenous areas in the uplands of China. In addition to use as coloring agents, Dong communities have historically utilized dye plants for their value for enhancing the nutritive, medicinal and preservative properties of foods. However, the persistence of plant-deri...

Antioxidant potential of the fungal dye, produced by a strain selected from the collection of Epicoccum nigrum bioresearch platform (acronym MIUG) was partially characterized in previous studies. However, the fungal dye antioxidant capacity compared with other potential colorant inhibitors of lipid peroxidation (e.g. cochineal dye) has not been fully elucidated, especially regarding its behavio...
