Is aromatic hydrocarbon toxic? Effects on fish and whether contaminated fish can be eaten
The explosion at the No. 3 aromatic hydrocarbon plant of the Sixth Naphtha Cracker Complex in Mailiao Township has caused anxiety among residents near aquaculture fish ponds, who worry that their catch may be contaminated. On the 15th, scholars from the College of Public Health at National Taiwan University, who have long studied pollution issues related to the Sixth Naphtha Cracker Complex, together with the Institute of Toxicology, and the Changhua and Taixi experimental stations of the Fisheries Research Institute, went to 18 fish ponds in Changhua and Yunlin to take samples, hoping to understand the scope and extent of the explosion's impact.

Chiu Chia-pin, a project assistant professor at the College of Public Health at National Taiwan University, said that in the past, research on pollution from the Sixth Naphtha Cracker Complex mainly focused on the human body. This time, taking advantage of the explosion incident, it is hoped to advance understanding of the degree of impact of pollutants in different media, such as water, air and residues in organisms, etc. 0.15. On the 16th, the research team collected water, sediment, hard clams and foam from a total of 18 sites from Changhua to Yunlin for testing. Although no large-scale death of organisms was found on site, the contamination situation still could not be determined. It is expected that on the 17th the sampled contents will be sent to a testing unit.
Chou Yu-han, an assistant researcher at the Taixi Experimental Station of the Fisheries Research Institute, explained that the sampling range included 7 sites in Fangyuan Township, Changhua, 1 site in Dacheng Township, 5 sites in Mailiao Township and 5 sites in Taixi Township, for a total of 18 sites. Among them, the Mailiao and Taixi areas were randomly sampled according to distance from the explosion site. In the previous water quality sampling on the 8th, substances such as nitrite and ammonia were all detected as normal. The sampling on the 15th also found no large-scale death of organisms, but the detailed degree of contamination still awaits the test results of the College of Public Health scholars before it can be determined. Everyone is reminded that if you pick upfish contaminated by aromatic hydrocarbons, do not eat them, otherwise it will cause health safety problems.
