Abstract

 Waste incineration and recycling of rubber in the past may be a source of toxic organic compounds such as polycyclic aromatic hydrocarbons (PAHs) that greatly affect the surrounding environment at the Division 330, Military Region 9. A total of 17 PAHs were analyzed in the environment (soil, mud, sediment) and organisms (catfish) collected around the former burning and recycling areas of rubber and increasing area in Division 330. The results showed that the concentration of PAHs in soil samples ranged from 46.7-161.8 μg/kg dry, sediment samples ranged from 60.4-84.3 μg/kg dry, mud samples ranged from 71.6-78.5 μg/kg dry and fish samples ranged from 99.1-116.7μg/kg wet. In particular, PAHs with three benzene rings predominate with 32.7-45.9% in environmental samples and 40% in biological samples, indicating that the origin of PAHs mainly comes from combustion. Although the total PAHs in the samples were less than the allowed limits, the Benzo [a] pyrene in fish samples showed a slightly higher result than the EU food regulations, for See the accumulation of PAHs in organisms that are likely to affect human health.
