When released into the environment, ethyl propanoate can partition into different compartments, including air, water, and soil. In the atmosphere, it undergoes photochemical degradation, contributing to the formation of ground-level ozone and other secondary pollutants. The half-life of ethyl propanoate in air is estimated to be relatively short, typically a few days, which limits its long-range transport potential.

In aquatic environments, ethyl propanoate's moderate water solubility allows it to dissolve and potentially interact with aquatic organisms. Its low octanol-water partition coefficient suggests limited bioaccumulation potential in aquatic food chains. However, the compound's ability to interact with biological membranes raises concerns about its effects on aquatic life, particularly on sensitive species or during critical life stages.

Soil contamination by ethyl propanoate can occur through spills or improper disposal. In soil, the compound is expected to have high mobility due to its physicochemical properties. This mobility increases the risk of groundwater contamination, potentially affecting drinking water sources and subterranean ecosystems.

The biodegradability of ethyl propanoate is an important factor in assessing its environmental persistence. Studies have shown that the compound is readily biodegradable under aerobic conditions, with microbial communities capable of metabolizing it as a carbon source. This characteristic helps mitigate long-term environmental accumulation but may also lead to temporary oxygen depletion in affected water bodies during rapid biodegradation processes.

Ecotoxicological studies on ethyl propanoate have revealed varying degrees of toxicity to different organisms. Aquatic invertebrates and fish may experience acute or chronic effects depending on exposure concentrations and duration. The compound's interaction with biological membranes can disrupt cellular functions, potentially leading to physiological stress or mortality in exposed organisms.
