Are aromatic hydrocarbons toxic? what are the effects on fish? Can fish contaminated by aromatic hydrocarbons still be eaten?

The explosion of the No. 6 Light aromatic hydrocarbon Plant in Mailiao Township has caused nervousness among people in nearby farmed fish ponds, fearing that their catch will be contaminated. On the 15th, scholars from the School of Public Health of National Taiwan University, who have been studying the issue of six light pollution for a long time, worked with the Toxicology Laboratory, Changhua and Taixi Test sites to sample fish ponds from Changhua and Yunlin, hoping to understand the scope and extent of the explosion.

Qiu Jiabin, an assistant professor in the project of the School of Public Health, National Taiwan University, said that in the past, most of the subjects of the six minor public hazards were in the human body, and this explosion is expected to promote the influence of pollutants in different media, such as water, air and residues in organisms. 0.15. On the 16th, the research team collected water, sediment, clams and foam from 18 places from Changhua to Yunlin, although no large-scale death of organisms was found at the scene. But it is still impossible to determine the situation of pollution. It is expected that the contents of the samples will be transferred to the inspection unit on the 17th.

Zhou Yuhan, an assistant researcher at the Taixi proving ground of the Fisheries Research Institute, explains that the sampling range includes seven in Changhua Fangyuan Township, one in Dacheng, five in Mailiao Township and five in Taixi Township, a total of 18. Among them, Mailiao and Taixi are randomly sampled according to the distance from the site of the explosion. During the previous water sampling on the 8th, nitrous acid and ammonia and other substances were detected normally, and no large-scale death of organisms was found in the 15th sampling, but the detailed degree of pollution can only be determined by the results of the examination by scholars of the Institute of Public Health. Remind everyone to pick up fish contaminated by aromatic hydrocarbons, do not eat, otherwise it will cause health safety problems.
