The chemical with CAS 110 - 63 - 4 is 1,4 - Butanediol. It is a widely used organic compound with various applications in industries such as plastics, textiles, and pharmaceuticals. As a supplier of CAS 110 - 63 - 4, understanding its ecotoxicity data is crucial not only for environmental protection but also for ensuring the safety of our customers and the broader ecosystem.
Ecotoxicity in Aquatic Environments
Aquatic environments are highly sensitive to chemical pollutants. For 1,4 - Butanediol, several studies have been conducted to assess its impact on different aquatic organisms.
Fish Toxicity: Research has shown that the acute toxicity of 1,4 - Butanediol to fish is relatively low. In a standard 96 - hour acute toxicity test, the median lethal concentration (LC50) for fish such as rainbow trout and zebrafish is typically above 1000 mg/L. This indicates that under normal environmental conditions, 1,4 - Butanediol is not likely to cause immediate death to fish populations. However, long - term exposure at lower concentrations may still have sub - lethal effects, such as reduced growth rates, impaired reproduction, and altered behavior.
Invertebrate Toxicity: Aquatic invertebrates are also important indicators of water quality. Tests on Daphnia magna, a common freshwater invertebrate, have revealed that the 48 - hour LC50 value for 1,4 - Butanediol is generally in the range of several hundred to over a thousand mg/L. Similar to fish, chronic exposure to sub - lethal concentrations can affect the survival, growth, and reproduction of invertebrates. For example, it may disrupt the molting process in crustaceans, which is essential for their growth and development.
Algal Toxicity: Algae are the base of the aquatic food chain, and their health is vital for the overall functioning of aquatic ecosystems. Studies on the toxicity of 1,4 - Butanediol to algae have shown that it can inhibit algal growth at relatively high concentrations. The effective concentration (EC50) for inhibiting algal growth is usually in the range of tens to hundreds of mg/L. At lower concentrations, the impact on algal photosynthesis and cell division may be less significant, but it can still have cascading effects on the entire food web.
Ecotoxicity in Terrestrial Environments
Although 1,4 - Butanediol is more commonly associated with industrial and aqueous applications, it can also enter terrestrial environments through various routes, such as wastewater discharge, accidental spills, or improper waste disposal.
Soil Microorganisms: Soil microorganisms play a crucial role in nutrient cycling, soil fertility, and plant health. Research on the impact of 1,4 - Butanediol on soil microorganisms has shown that at low concentrations, it may have a negligible effect on microbial activity. However, at high concentrations, it can inhibit the growth and metabolic activity of soil bacteria and fungi. For example, it may interfere with the decomposition of organic matter, which can lead to a decrease in soil fertility over time.
Earthworms: Earthworms are important soil organisms that contribute to soil structure and aeration. Acute toxicity tests on earthworms have indicated that 1,4 - Butanediol has a relatively low toxicity. The LC50 values for earthworms exposed to 1,4 - Butanediol in soil are usually high, suggesting that under normal circumstances, it is not likely to cause significant harm to earthworm populations. However, long - term exposure to contaminated soil may still affect their behavior and reproduction.
Biodegradability
One of the important factors in assessing the ecotoxicity of a chemical is its biodegradability. 1,4 - Butanediol is considered to be readily biodegradable under aerobic conditions. In sewage treatment plants, it can be efficiently degraded by microorganisms, which helps to reduce its environmental impact. Studies have shown that in aerobic activated sludge systems, a significant portion of 1,4 - Butanediol can be degraded within a few days.
Under anaerobic conditions, the biodegradation process is slower, but it still occurs. This biodegradability property is beneficial as it means that 1,4 - Butanediol is less likely to persist in the environment and cause long - term ecotoxicological problems.
Comparison with Other Related Chemicals
It is useful to compare the ecotoxicity of 1,4 - Butanediol with other related chemicals. For example, 3 - Methyl - 3 - buten - 1 - ol / Isoprenol CAS 763 - 32 - 6 and Ethylene Glycol Diethyl Ether CAS 629 - 14 - 1 and Diethylene Glycol Diethyl Ether / 2 - Ethoxyethyl Ether CAS 112 - 36 - 7 are also organic chemicals with different applications.
Isoprenol has different chemical properties and ecotoxicity profiles compared to 1,4 - Butanediol. Its aquatic toxicity may vary depending on the specific organism tested, but in general, it also has a relatively low acute toxicity to fish and invertebrates. Ethylene Glycol Diethyl Ether and Diethylene Glycol Diethyl Ether have been studied for their potential environmental impacts. They may have different effects on aquatic and terrestrial organisms due to their different chemical structures and solubilities.
Regulatory Considerations
Based on the ecotoxicity data of 1,4 - Butanediol, regulatory agencies around the world have set certain guidelines and limits for its use and disposal. In the European Union, for example, chemicals are evaluated under the REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulation. 1,4 - Butanediol is subject to specific requirements regarding its production, import, and use to ensure environmental safety.
In the United States, the Environmental Protection Agency (EPA) also monitors and regulates the use of chemicals like 1,4 - Butanediol to protect human health and the environment. These regulations are designed to minimize the potential ecotoxicological risks associated with the chemical.
