Determination of PAH (Polyaromatic Hydrocarbons) in Sewage Sludge

Polycyclic aromatic hydrocarbons (PAHs) are an important group of organic pollutants found in sewage sludge. Because of their persistence and toxic potential, their use in farmland requires caution. In advanced laboratories, gas chromatographic-mass spectrometry (GC-MS) method is applied to determine the presence of polycyclic aromatic hydrocarbons in sewage sludge.

Polycyclic aromatic hydrocarbons (PAHs) are very dangerous compounds and, due to their lipophilicity, easily cross biological membranes and accumulate inside organisms, causing damage to their genetic structure. Scientific interest in PAHs is related to their genotoxicity. They were first studied in the 1930s.

Today, the management and disposal of sewage sludge is a serious environmental problem worldwide. China alone produces one hundred million tons of sewage sludge annually, and a better understanding of the extent and risk of pollution is critical to enforcing environmentally safe regulations and practices.

With the growth of urbanization, changes in the industrial structure and increasing awareness of environmental protection, drinking water treatment plants and wastewater treatment plants are now being built more comprehensively and advanced testing methods are applied.

In the test, analysis, measurement and evaluation studies carried out in our organization, national and international standards and applicable legal regulations are complied with and reliable and impartial results are obtained. These studies are based on the latest technological equipment, trained and experienced staff and modern methods. Among the numerous tests carried out in this context, there are also PAH (polyaromatic hydrocarbons) determination services in sewage sludge.
