Tungsten spheres have had many important impacts on our productive lives and are used in many fields, such as industry, medicine, and the military. But tungsten and tungsten products, including tungsten spheres, are classified as emerging pollutants by the U.S. Environmental Protection Agency (EPA). Let's take a look.
The following is a list of contents:
l Effects of tungsten spheres on soil

l Effects of tungsten salt on animals and humans
Tungsten spheres are widely used in metallurgy, chemical, electronic, mechanical, and military fields because of their high hardness, high melting point, and chemical stability. However, in the past 200 years, with the mining and smelting of tungsten ore and the application of tungsten products in various industries, the pathways for tungsten and its compounds to enter the soil have increased, and the potential hazards to the soil environment, plants and animals, and humans have become increasingly evident. Compared to other heavy metals, human knowledge of tungsten, especially the biogeochemical processes in soil, is lacking in terms of its effects on microorganisms, plants and animals, and human health.
In areas such as tungsten mining and metallurgy and military activities, soil tungsten levels greatly exceed environmental background values. Among them, tungsten spheres, as a type of ammunition core, are the main cause of excessive soil tungsten content in areas of military activities. Rough mining and military activities can cause tungsten content in soil to reach hundreds or even thousands of times the environmental background value, and its potential ecological and environmental risks cannot be ignored.
Discarded tungsten spheres or tungsten alloy balls used as bullet cores are left in the soil and taken up by plants. Plants can take up tungsten in the soil through the root system, and the tungsten uptake and accumulation by different plants vary greatly, as does the accumulation of tungsten by different organs of plants.
The tungsten in the soil in the natural environment is different from the tungsten brought to the soil by anthropogenic activities. Only a small part of the tungsten formed by anthropogenic activities such as the decomposition of tungsten balls left behind can be used by plants, and more are enriched in the plants, while high concentrations of tungsten have a significant hindering effect on plant growth and can even bring death to plants. There are significant differences in the toxic effects of tungsten on different plants, but the relevant mechanisms are not yet clear.
The tungsten produced by the decomposition of tungsten spheres left behind or discarded in the environment can be transferred and accumulated in animals through various pathways, causing potential harm to the growth and development of animals. Even before decomposition, tungsten is accidentally ingested by animals, which may pose a threat to their life safety. Phytophagous animals ingesting plants contaminated with tungsten will also be enriched in their bodies if they are unable to decompose, bringing tungsten poisoning to themselves. According to some studies, tungsten is also a reproductive toxicant that can cause significant reproductive harm.
According to some speculations, childhood leukemia is even associated with long-term tungsten exposure, and cardiovascular disease and thyroid disease may also be associated with high tungsten concentrations. This means that whether the human body is chronically exposed to tungsten, ingesting contaminated drinking water or crops, or eating animals that are enriched with tungsten in their bodies, there will be effects and even potential toxic effects on the human body. The accidental ingestion of tungsten spheres by children can also be life-threatening.
