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.

What are the causes of contamination in Lingzhi (Ganoderma) spawning?
1. Damage contamination (1) Container damage: mechanical damage caused by failure to handle with care during filling, sterilization, inoculation, transport and cultivation. (2) Air-pocket damage: rapid heating, pressure rise or rapid cooling during sterilization; excessive exhaust speed, causing bags to swell with air and rupture. 2. Cotton plug contamination (1) Cotton plug contamination: the test tube mouth is stained with culture medium or the bottle (bag) mouth is not clean, or the culture medium comes into contact with the cotton plug. (2) Cotton plug dampened: improper stacking during sterilization, too much water added, or unreasonably built sterilization stove, or culture

How to prevent and control green mold contamination in mushroom cultivation?
In production, strictly avoid applying excessive formaldehyde in the inoculation box or inoculation room, so as to prevent formaldehyde from turning into formic acid and forming an acidic environment. Lime powder should be spread around the culture room, and any spawn found contaminated by green mold should be dug out promptly. After sowing, check the spawn blocks in time; if green mold contamination is found, immediately dig it out and replace it with new spawn blocks. Choose to cultivate in low-temperature and dry seasons as much as possible to reduce disease incidence. During the mycelium healing stage, cover with plastic film, ventilate moderately, and pay attention to lowering the temperature. In the later stage, the plastic film must not be lifted too early, to prevent the healing spawn blocks from being attacked. When green mold appears on the spawn blocks, promptly scrub with 40% sulfur-polycarbamate suspension concentrate or 50% carbendazim wettable powder 800-fold solution.
