CAS 115-86-6, also known as Tris(2-chloroethyl) phosphate (TCEP), is a chemical compound that has been widely used in various industries. As a supplier of CAS 115-86-6, I understand the importance of being aware of its potential environmental hazards. In this blog, I will explore the possible impacts of CAS 115-86-6 on the environment based on scientific research and industry knowledge.
Chemical Properties and Uses of CAS 115-86-6
Tris(2-chloroethyl) phosphate is a colorless to pale yellow, oily liquid with a slight odor. It is a halogenated organophosphate ester, which is commonly used as a flame retardant, plasticizer, and additive in a variety of products. These include plastics, rubber, textiles, polyurethane foams, and electronic equipment. Its flame-retardant properties make it an attractive choice for manufacturers looking to meet fire safety standards.
Environmental Persistence
One of the primary concerns regarding CAS 115-86-6 is its environmental persistence. This chemical is resistant to degradation in the environment, which means it can remain in soil, water, and air for extended periods. Studies have shown that TCEP can be detected in various environmental matrices, including surface water, sediment, and even in the air near industrial areas where it is produced or used.
The persistence of CAS 115-86-6 is due to its chemical structure. The chlorine atoms in the molecule make it more stable and less susceptible to breakdown by natural processes such as hydrolysis and photolysis. As a result, it can accumulate in the environment over time, leading to potential long-term effects on ecosystems.
Bioaccumulation and Biomagnification
Another significant hazard of CAS 115-86-6 is its ability to bioaccumulate and biomagnify in the food chain. Bioaccumulation refers to the process by which a chemical accumulates in the tissues of an organism over time. Biomagnification, on the other hand, occurs when the concentration of a chemical increases at higher trophic levels in the food chain.
TCEP has been found to bioaccumulate in aquatic organisms such as fish and shellfish. Once ingested, it can be stored in the fatty tissues of these organisms, where it can reach higher concentrations than in the surrounding environment. As predators consume these contaminated organisms, the concentration of TCEP in their bodies can increase further, leading to biomagnification.
The bioaccumulation and biomagnification of CAS 115-86-6 can have serious consequences for wildlife and human health. High levels of TCEP in the tissues of animals can cause a range of adverse effects, including reproductive problems, developmental abnormalities, and damage to the nervous system. In humans, exposure to TCEP through the consumption of contaminated food can also pose health risks.
Toxicity to Aquatic Organisms
CAS 115-86-6 is known to be toxic to aquatic organisms. Studies have shown that it can have acute and chronic effects on fish, invertebrates, and algae. Acute toxicity refers to the immediate effects of a chemical on an organism, while chronic toxicity refers to the long-term effects of exposure over time.
In fish, exposure to TCEP can cause a variety of symptoms, including reduced growth, impaired swimming ability, and damage to the gills and liver. Invertebrates such as daphnia and mussels are also sensitive to TCEP, and exposure can lead to reduced survival, reproduction, and feeding rates. Algae, which are an important part of the aquatic food chain, can also be affected by TCEP, with reduced growth and photosynthetic activity observed in laboratory studies.
The toxicity of CAS 115-86-6 to aquatic organisms can have significant ecological consequences. It can disrupt the balance of aquatic ecosystems, leading to changes in species composition and abundance. This, in turn, can have cascading effects on other organisms in the ecosystem, including humans who depend on aquatic resources for food and recreation.
Air Quality and Human Exposure
In addition to its effects on the aquatic environment, CAS 115-86-6 can also pose a risk to air quality and human health. TCEP can be released into the air during its production, use, and disposal. Once in the air, it can be transported over long distances and deposited in other areas, including residential and agricultural areas.
Human exposure to CAS 115-86-6 can occur through inhalation of contaminated air, ingestion of contaminated food and water, and dermal contact. Inhalation of TCEP can cause respiratory problems, such as coughing, wheezing, and shortness of breath. Ingestion of contaminated food and water can lead to systemic exposure, with potential effects on the liver, kidneys, and nervous system. Dermal contact with TCEP can cause skin irritation and allergic reactions.
Regulatory Measures
Due to the potential environmental and health hazards of CAS 115-86-6, many countries have implemented regulatory measures to control its use and release. In the European Union, TCEP is classified as a substance of very high concern (SVHC) under the REACH regulation. This means that its use is restricted, and companies are required to obtain authorization for its use in certain applications.
In the United States, the Environmental Protection Agency (EPA) has also recognized the potential risks of TCEP and has taken steps to regulate its use. The EPA has issued regulations limiting the use of TCEP in certain consumer products, such as children's toys and furniture.
Alternatives to CAS 115-86-6
As a supplier of CAS 115-86-6, I am aware of the growing demand for safer and more environmentally friendly alternatives. There are several alternative flame retardants and plasticizers available on the market that have lower environmental and health risks.
One such alternative is Isopropylate Triphenyl Phosphate 95. This product is a non-halogenated organophosphate ester that offers similar flame-retardant properties to TCEP but with lower toxicity and environmental persistence. Another alternative is Tris(chloropropyl) Phosphate TCPP-LO, which is a low-odor version of TCPP with reduced environmental impact. Tritolyl Phosphate is also a viable alternative that is widely used in the industry.
Conclusion
In conclusion, CAS 115-86-6, or Tris(2-chloroethyl) phosphate, poses several potential hazards to the environment. Its environmental persistence, bioaccumulation and biomagnification potential, toxicity to aquatic organisms, and impact on air quality and human health are all significant concerns. As a supplier, it is our responsibility to be aware of these hazards and to take steps to minimize the environmental impact of our products.
We recommend that our customers consider using alternative products such as Isopropylate Triphenyl Phosphate 95, Tris(chloropropyl) Phosphate TCPP-LO, and Tritolyl Phosphate to reduce the environmental and health risks associated with CAS 115-86-6. If you have any questions or would like to discuss your specific needs, please feel free to contact us for further information and to start a procurement negotiation.
