how should we protect ourselves against heavy metal particle pollutants - Blog

In industrial production scenarios, heavy metal particle pollutants are widely derived from many core industries, including mining and mineral processing, metal smelting and casting, electroplating and surface treatment, welding and cutting, battery manufacturing and recycling, electronic manufacturing and waste electronic dismantling, garbage incineration and hazardous waste treatment, and ceramic, glass and enamel production. During the production process of these industries, dust, aerosols or flue gas containing various heavy metals such as lead, chromium, cadmium, mercury, nickel and arsenic will be generated. Such pollutants have the characteristics of small particle size, strong toxicity, difficulty in degradation and easy accumulation. Long-term inhalation will deposit in the human lungs, liver, kidneys and nervous system, causing lung damage, heavy metal poisoning, neurasthenia, blood system diseases, and even increasing the risk of cancer, which seriously threatens the occupational health of practitioners.

So how should we protect ourselves against heavy metal particle pollutants is very important to our healthy !

I. Industries Prone to Generating Heavy Metal Particle Pollutants

1. Mining and Mineral Processing

Mining of ores such as lead, zinc, copper, nickel, mercury, and arsenic, where the concentration of heavy metals in dust is extremely high.

2. Metal Smelting and Casting

Steelmaking, ironmaking, non-ferrous metal smelting, and alloy casting, which generate flue gas and dust containing heavy metals at high temperatures.

3. Electroplating and Surface Treatment

Chrome plating, nickel plating, zinc plating, pickling, and passivation, which are prone to generating aerosols and dust containing heavy metals.

4. Welding and Cutting Industry

Stainless steel welding, galvanized sheet welding, and alloy welding, where the fumes contain manganese, chromium, nickel, lead, etc.

5. Battery Manufacturing and Recycling

Production and dismantling of lead-acid batteries and lithium batteries, with prominent pollution of lead, cadmium, mercury, and nickel.

6. Printing, Ink, Pigment, and Coating Production

Pigments containing lead, chromium, and cadmium form dust during batching, grinding, and spraying processes.

7. Electronic Manufacturing and Waste Electronic Dismantling

Circuit board processing, soldering, chip manufacturing, and precious metal extraction, which involve lead, mercury, and cadmium.

8. Garbage Incineration and Hazardous Waste Treatment

Incineration fly ash is enriched with various heavy metals such as lead, cadmium, mercury, and arsenic.

9. Ceramic, Glass, and Enamel Production

Glazes contain lead, cadmium, and zinc, and heavy metal dust is generated during firing and polishing.

II. Correct Protection Methods Against Heavy Metal Particles

1. Respiratory Protection (Most Critical)

Prioritize the use of KN95 / KN100, FFP2 / FFP3 grade protective masks.

When dealing with highly toxic heavy metals such as lead, cadmium, arsenic, radioactive heavy metals, or oily fumes:

Choose professional dust masks with oil-proof protection (KP class, FFP class).

High-concentration, enclosed environments: It is recommended to use a full-face mask + toxic gas filter cartridge + filter cotton.

(For heavy metal vapors / fumes, a comprehensive or special toxic gas filter cartridge can be equipped.)

2. Skin and Body Protection

Wear work clothes, protective gloves, and protective shoes to avoid skin contact.

Change clothes, wash hands, and wash face must after work to prevent dust from adhering to the body and being brought into living scenes.

3. Engineering and Management Protection

Install gas collection, dust suction, and purification devices.

Implement wet operation and closed production to reduce heavy metal particles.

Conduct regular environmental monitoring and occupational health check-ups.
