In the electronics industry, this can be a concern as some of these materials are used in manufacturing. For example, we know that chlorine is used to keep drinking water safe by killing off unwanted bacteria. It is not harmful to humans in such a low concentration.
However, concerns arise when chlorine gas is released into the air. The use of nonbrominated epoxy resins can leave chlorine as a residual material during the production of circuit boards. Concentrations are typically below ppm, but the concern lies in the fact that too much chlorine may be dangerous to humans and the environment. Other sources of halogens in circuit boards include fiberglass sizing, epoxy curing agents and accelerators, resin wetting and de-foaming agents, flux residues, and contamination from handling.
The main issue involving halogens and the electronics industry is the unregulated disposal of materials by incineration. Coelomate vs. Ocean vs. Judge vs. Flag vs. Forbear vs. Awesomely vs. Fat vs. Sonhood vs.

Mandate vs. Ivermectin vs. Skinwalker vs. Socialism vs. Man vs. Supersonic vs. Gazelle vs. Astatine is mostly ignored in chemistry; radioactive and rare, it does not often appear in nature. When halogens combine with other elements, the resulting compound is called a halide.
For example, a halogen attached to an alkane molecule a halogen in a bond with a hydrocarbon is an alkyl halide, also known as a haloalkane. In a less common usage, the word "halide" also refers to a halogen ion. Halogen atoms commonly acquire an extra electron. In chemistry terms, that makes them ions. For an example of halide ions, look no further than table salt. However, a halide will always have a negative charge. The salts having these ions are halide salts.
Furthermore, all these halides are colorless and occur in solid crystalline compounds. These solids have a high negative enthalpy of formation. Therefore, this means these solids easily get formed. There are specific tests from which we can identify the presence of a halide. For example, we can use silver nitrate to indicate the presence of chlorides, bromides, and iodides. That is because, when we add silver nitrate to a solution containing chloride ions, silver chloride precipitate.
If we add silver nitrate to bromide containing solution, a creamy silver bromide precipitate forms. For iodide ion containing solutions, it gives a green colored precipitate. But, we cannot identify fluoride from this test since fluorides cannot form precipitates with silver nitrate.
