It was reported that an illegal chemical waste dumping incident occurred in Shunwang Subdistrict, Zhucheng City, Shandong Province on January 31, claiming four lives due to poisoning. Relevant responsible persons have been detained by police. Hazardous waste transported from other regions was dumped into sewage pipes, and toxic gas volatilized and leaked out, causing personnel poisoning.
Despite full emergency treatment, four poisoned victims died. Other people showing poisoning symptoms are out of life danger and under hospital observation. Medical teams preliminarily confirmed hydrogen sulfide, a highly toxic chemical, as the toxic substance. Even short-term inhalation of hydrogen sulfide at a certain concentration can cause severe harm. Two medical staff suffered mild poisoning while rescuing affected villagers.
Hazardous chemical waste disposal and decontamination work have been completed at the scene. Rainwater pipe networks on both sides of nearby roads have been thoroughly cleaned. All chemical waste, storage tanks and contaminated soil inside the abandoned factory involved have been removed. Multiple professional monitoring and assessments by experts from Shandong Provincial Department of Ecology and Environment show air quality indicators in the area have returned to normal.
Hydrogen sulfide is an acutely lethal toxic gas at room temperature. Low-concentration hydrogen sulfide damages eyes, respiratory system and nervous system, and inhalation of high-concentration hydrogen sulfide can lead to sudden death.
Shenzhen Wuliang Sensor Technology Co., Ltd. supplies British DDS industrial electrochemical gas sensors, covering toxic gases including O₂, CO, H₂S, H₂, NO, NO₂, NH₃, Cl₂, SO₂ and ETO. These sensors are widely applied in coal mining, petroleum, chemical, steel and municipal engineering sectors.

The chemical industry features abundant toxic and harmful gases and high safety risks. Harmful gases such as carbon monoxide, sulfur dioxide, hydrogen sulfide and nitrogen oxides, as well as toxic organic vapors including benzene, aldehydes and ketones are generated during production, posing threats to personnel safety and ecological environment.
Chemical enterprises shall prioritize accident prevention, eliminate gas leakage and realize waste gas recovery and comprehensive utilization. Industrial environmental monitoring systems equipped with flammable and toxic gas detectors and alarms can be deployed to real-time monitor gas concentration and environmental parameters in chemical workshops.
