What are the possible environmental pollution and health risks in the lead die-casting process?

Although the lead die-casting process has significant advantages in production efficiency and finished product quality, it may bring certain environmental pollution and health risks when using lead as the main raw material. Lead is a toxic heavy metal. Long-term contact and inhalation of lead dust or lead smoke are seriously harmful to the human body and may cause a variety of health problems. In addition, the production and processing of lead may cause pollution to the surrounding environment.
The biggest health risk in the lead die-casting process comes from the volatilization and inhalation of lead. When lead melts at high temperatures, it releases lead vapor and tiny particles, which may be inhaled by workers, especially in poorly ventilated working environments. Long-term exposure to lead smoke or lead dust may lead to lead poisoning. Symptoms of lead poisoning include headaches, fatigue, insomnia, memory loss, and in severe cases, it may also cause health problems such as neurological diseases, kidney damage, and anemia. Especially for pregnant women and children, lead has a greater harm to their nervous system and development.
The waste gas and wastewater that may be generated during the lead die-casting production process are also one of the sources of environmental pollution. The emission of lead vapor and harmful gases, if not effectively treated, will have a negative impact on air quality and cause atmospheric pollution. At the same time, the coolant and lubricating oil used in the production process and the wastewater generated during the cleaning process contain toxic substances. If they are not discharged properly, they may pollute water sources and soil and affect the health of the ecological environment. In particular, water bodies and land near production facilities will be polluted for a long time if not properly treated, affecting the surrounding ecosystem.
The waste generated during the lead die-casting process, such as waste of lead alloys, remnants of lead molds, and dust generated, can also become a potential source of environmental pollution if not properly handled. The waste may still contain a certain proportion of lead. If it is not properly recycled and disposed of, the lead will enter the soil and groundwater, causing long-term environmental pollution. The stacking of waste may also affect the surrounding air and water quality, further exacerbating environmental problems.
In order to mitigate these health and environmental risks, the lead die-casting industry must take strict safety measures and environmental protection measures. First, workers should wear appropriate protective equipment, such as dust masks, protective glasses and protective clothing, to reduce the chance of direct contact with lead dust and vapor. In addition, strengthen the ventilation system of the workshop and use high-efficiency air filtration devices to discharge harmful gases and lead vapor to a safe area to prevent them from entering the workers' breathing zone. Secondly, for the treatment of waste gas and wastewater, lead die-casting enterprises need to install effective waste gas purification and wastewater treatment facilities to ensure that emissions meet environmental standards and avoid pollution to the environment.
Waste recycling and reuse are also important ways to reduce pollution. The waste generated by lead die-casting should be professionally recycled and treated, which can not only reduce resource waste, but also avoid the long-term impact of lead pollution on soil and water sources. For wastes such as lead dust and lead slag generated during the production process, they should be harmlessly treated in accordance with relevant regulations to avoid direct discharge into the environment.
