Polychlorinated naphthalene testing

Polychlorinated naphthalenes are a class of persistent organic compounds that are widely used as capacitors, transformer media, lubricant additives, cable insulation and preservatives.

additives, cable insulation and preservatives, etc. The chlor-alkali industry, waste incineration and metal smelting also produce polychlorinated naphthalene pollution. Polychlorinated naphthalenes are ubiquitous in the environment and have been detected in air, soil, water, sediments, various organisms, and humans.

These polychlorinated naphthalene series have a similar structure and cystic properties to polyazonium bistrione (PCB), and can interact with or activate certain specific enzymes to change the biochemical properties of cells, thereby producing certain toxic effects.

Therefore, polychlorinated naphthalenes, as a type of persistent organic pollutants, have attracted increasing attention. Zhongke Testing focuses on material compliance testing and provides polychlorinated naphthalene testing services.
