Industrial Exhaust Gas Detection Service

1. Introduction to Industrial Waste Gas

Industrial waste gas refers to the general term for various pollutant-containing gases emitted into the air during fuel combustion and production processes within enterprise premises. These waste gases include carbon dioxide, carbon disulfide, hydrogen sulfide, fluorides, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid mist, soot, and industrial dust. When released into the atmosphere, they pollute the air. These substances enter the human body through the respiratory tract via different pathways, some causing direct harm, while others accumulate over time, posing even more severe health risks. Different substances have varying impacts.

2. Causes of Pollution

Air pollution is one of the most prominent environmental issues in China today. Industrial waste gas is a significant source of air pollutants. The large-scale emission of industrial waste gas into the atmosphere inevitably degrades air quality, poses serious health hazards, and causes substantial economic losses. Harmful substances in industrial waste gas enter the human body through the respiratory tract and skin, leading to temporary or permanent damage to systems and organs such as the respiratory tract, blood, and liver. Particularly, polycyclic aromatic hydrocarbons like benzopyrene can directly cause cancer, warranting high attention.

Industrial waste gas includes organic and inorganic waste gases. Organic waste gases primarily consist of various hydrocarbons, alcohols, aldehydes, acids, ketones, and amines. Inorganic waste gases mainly include sulfur oxides, nitrogen oxides, carbon oxides, halogens, and their compounds.

3. Hazards

(1) Hazards to Human Health: Humans need to breathe air to sustain life. An adult breathes approximately 20,000 times a day, inhaling 15 to 20 cubic meters of air. Therefore, polluted air directly impacts human health. The hazards of air pollutants to the human body are multifaceted, primarily manifesting as respiratory diseases, physiological dysfunction, and irritation of mucous tissues such as the eyes and nose.

(2) Hazards to Plants: Air pollutants, especially sulfur dioxide and fluorides, pose severe threats to plants. When pollutant concentrations are high, they cause acute damage to plants, resulting in leaf surface lesions or direct wilting and shedding. At lower concentrations, they cause chronic damage, leading to leaf chlorosis or seemingly asymptomatic effects that nonetheless impair physiological functions, reducing plant yield and quality.

(3) Impact on Weather and Climate: The influence of air pollutants on weather and climate is highly significant.
