Persistent organic pollutants (POPs) are organic compounds that are resistant to environmental degradation through chemical, biological, and photolytic processes. Because of their persistence, these chemical substances are transported across international boundaries far from their sources and they persist in the environment, bioaccumulate through the food web, and pose a great hazard to human health and the environment.

SVHC ,“Substance of Very High Concern”, refers to any substance that has adverse effects on human health and the environment.

Phthalates is a general term for compounds which result from the reaction of phthalic anhydride and alcohol. Such substances are mainly employed as plasticisers make plastics and rubber more piable. They are widely used in electronic and electrical equipment (EEE), toys, coatings, inks, garments, packaging materials, detergents, lubricants and personal care articles, etc. But when the concentration of phthalates exceeds a certain level, it may disrupt endocrine of human bodies, bringing harm to the development and health of children.

Azodye almost exists in all colours as one of the most widely-used synthetic dyestuffs in printing technique (for textiles). It is used for dyeing and printing of natural and synthetic fibres, also for the colouring of paints, plastics and rubber.

Formaldehyde (molecular formula: HCHO) is colorless and has a pungent, irritating odour. As a toxicant, it can also interact with proteins. So inhaling of high concentration of formaldehyde may lead to severe irritation and inflammability to respiratory tract, eye irritation, headache, bronchus and asthma. Furthermore, dermatitis, stains and necrosis would be caused if it comes in direct contact with the skin. Formaldehyde is easily dissolved in water, alcohol and ether. Its water solution with 35% to 40% formaldehyde is also known as “formalin”, which is commonly applied as a preservative. In addition, it is widely applied as reactants in finishing auxiliaries for textiles, such as resin finishing agents, fixing agent, softener and bender. In our daily life, we may find formaldehyde present in synthetic textiles, garments, leather, bedding and curtains.
