Persistent Organic Pollutants (POPs) is Chemical substances harmful to humans that exist in or accumulate within the bodies of animals and plants, and circulate in the natural environment over extended periods. Persistent organic pollutants (PoPs) are a class of naturally occurring or synthetic organic pollutants characterized by persistence, bioaccumulation, semi-volatility, and high toxicity. POPs include pesticides, industrial chemicals, and by-products unintentionally generated during industrial processes . These pollutants can travel long distances through various environmental media (air, water, organisms), crossing borders and affecting human health and ecosystems even in areas where PoPs were never used or produced, causing significant global harm.

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

PAHs Testing

California Proposition 65 (also known as Safe Drinking Water and Toxic Enforcement Act) was enacted as a ballot initiative in November 1986. Prop 65 businesses are required to provide a "clear and reasonable" warning before knowingly and intentionally exposing anyone to a listed chemical “Known to the State” to cause cancer or reproductive harm.

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.

China has officially issued the new national standard for pet supplies, "Safety Technical Requirements for Companion Animal (Pet) Supplies" GB/T 43839-2024. This is not only the first national standard for pet supplies in our country but also a responsible commitment to pets and pet lovers. It will officially start a new chapter in pet supply safety from October 1st of this year. This standard applies to the manufacturing, sale, and safety evaluation of pet supplies.

On January 25, 2024, the State Administration for Market Regulation (National Standards Committee) held a press conference to introduce five national standards for the express delivery industry. Among them, "Limits of Heavy Metals and Specific Substances in Express Packaging" (GB 43352-2023) is the first mandatory national standard for express packaging in China, which has been implemented since June 1, 2024.

On December 29, 2022, the State Administration for Market Regulation (Standardization Administration of the People's Republic of China) approved and issued GB 28489-2022 Limits of Harmful Substances in Musical Instruments, which replaced the GB/T 28489-2012. The nature of the standard has been changed from recommended (GB/T) to mandatory (GB), and the new standard will be implemented on January 1, 2024.

Gel Permeation Chromatography (GPC), abbreviated as GPC, utilizes the differential elution time of molecules of various sizes through a gel column to separate molecules of different molecular weights in high polymers. The intensity and elution time of each eluted component are measured using a refractive index detector. By comparing the elution time of unknown samples with the standard curve of known standard materials in terms of elution time and molecular weight, the molecular weight and molecular weight distribution of each eluted component of the unknown sample can be determined.
