For those that continuously breathe in bromine, there is an increased chance of long-term lung problems of varying degrees.Ĭurrently, many brominated compounds are restricted by the RoHS directive. The blood pressure of an individual could drop to intolerable levels for internal organs, assisting in overall physical dysfunction. Sustained exposure to bromine can cause brain damage as well as kidney failure due to systemic poisoning. However, high concentrations of bromine can cause: Coincidentally, bromine is also a component of many pharmaceuticals in the health industry. Bromine is also being tested for use in batteries for electric vehicles. It is used in the agricultural industry as a pesticide. It, too, is used in water treatment for swimming pools and hot tubs as well as controlling bacterial growth and algae within industrial processes. – Trichloroethane solvents to clean computer chipsĪlthough bromine doesn’t have the notoriety and popularity with household products as its companion, it is still used in a variety of ways that many people may not consider. – Trichloroethylene solvents used in semiconductor development

Some of the uses of this material include: Although the element was initially an effective tool for development, the threat it poses can be difficult to bypass. Generally, there are many uses for chlorine-based components when developing electronics. Not only is it a threat to human life, but it is a toxic element that can cause severe damage to an eco-system. The effects of chlorine including the disposal and destruction of related products are prompting the Restriction of Hazardous Substances directive to consider placing chlorine on the list for electronic compliance. According to a study published in a previous edition of Pediatrics, children are eight times more likely to develop asthma while swimming in Chlorine treated pools as opposed to not (1). – Burning sensation in nose, throat and the eyesĬontinued exposure to chlorine can cause severe complications such as pulmonary edema, or consistent fluid in the lungs. Some of the symptoms of chlorine exposure include: However, dangerous concentrations of chlorine can pose certain health risks. In small and diluted doses, this element can help in the protection of life from illnesses developed by virus and bacterial strains. It is a prime ingredient used in bleaches for cleaning as well as sterilizing pools to kill off bacteria. The element chlorine is used in a wide array of products. Each provides a specific benefit to the overall safety and functionality of electronics but pose a threat to the continuity of life for humans and nature. While there is still debate on the toxicity of halogens within PCB development, there are two primary elements that constitute the general consensus of a halogen-free circuit board. Although the composition themselves provide certain benefits to the development of electronics, they are harmful to human life in one way or another. As humanity develops an increased understanding of the threats that past materials present to life in today’s world, manufacturers are changing methods and finding new materials that don’t pose a threat to individuals working with such creations.Ĭommon compounds that are used in PCB developments belong to the family of Halogen elements. During the early days of PCB development, many toxic compounds were used as either a cost-saving aspect of manufacturing or because of the specific, helpful nature of the element. The Importance of a Halogen-free Printed Circuit Boardsĭuring the development of printed circuit boards, there are many compounds and elements that are utilized for a variety of purposes.
