Determination of polyaromatic hydrocarbons (PAH)

When organic compounds are not fully burned, organic compounds are called polyaromatic hydrocarbons, or PAHs. Water, air, cigarette smoke, food and textile products that enter the human body as a result of contact with the skin these compounds cause poisoning and even create carcinogenic effects over time. There are numerous polyaromatic hydrocarbon compounds detected in nature. Of these, only 16 are dangerous to human health.

The biggest problem that causes environmental problems in the textile sector is the wastewater released to nature and the chemicals in them. Besides, air emissions, odors, solid wastes and energy consumption also cause some problems in certain treatment processes.

A significant part of the total emissions from the activities in the textile sector depends on natural fibers, preparation chemicals, yarn lubricants and similar substances already present on the raw material before finishing. They are usually removed from the fibers during the pretreatment process prior to dyeing and finishing. Disposal of such auxiliary chemicals in this way not only allows the discharge of organic substances, but also the discharge of harmful compounds such as polyaromatic hydrocarbons.

However, some polyaromatic hydrocarbons (PAHs) may still remain on the textile products. This can be absorbed through the skin and cause undesirable disturbances in the human body.

Therefore, testing and analysis studies are carried out by the authorized laboratories in order to determine whether there are residues of polyaromatic hydrocarbons (PAHs) in textile products based on domestic and foreign legal regulations and published criteria and standards.

In the Regulation on the Control of Industrial Air Pollution issued by the Ministry of Environment and Forestry, it also published tables showing the limit values ​​for carcinogenic substances and aromatic hydrocarbons.

The laboratories that will carry out these tests must have a strong technological background and a trained and experienced staff.
