A review of phathalates in water: A toxic threat to aquatic life
AI summary Read the abstract
Researchers reviewed the aquatic toxicity of phthalate ester plasticizers across microorganisms, algae, invertebrates, and fish, finding that lower-molecular-weight phthalates are the most harmful and that these ubiquitous plastic additives pose broad ecological risks to aquatic ecosystems.
Phthalate esters are used as plasticizers to enhance flexibility and durability in a variety of products. A summary of the toxicity of phthalate esters was reviewed for microorganisms, algae, invertebrates and fish in the aquatic environment. The studies showed phthalates of lower molecular weights were implicated in acute and chronic phthalate toxicity in the aquatic environment. While higher molecular weight phthalate was not acute or chronic in terms of toxicity in the aquatic environment excerpt for daphnids, which occurred when true solubility of water was higher than the test concentration of exposure. Although some of the major routes of phthalates are water and effluents, leaching and other diffuse sources, but the concentration along the ecological food chain is via bioaccumulation and bioamplification, since humans are top of the food chain. Therefore, high concentration may occur in the human diet and results in the ill health effects. The aquatic system thus needs to be monitored, preserved and protected from phthalate esters toxicity.

Phthalate-induced effects in algae and fishes: insights into environmental toxicology
AI summary Read the abstract
This review of existing research found that phthalates—chemicals commonly found in plastics and personal care products—are harming fish and algae in waterways by disrupting their hormones, reproduction, and basic life processes. Since these chemicals build up in the food chain and we're exposed to them through contaminated water and seafood, this pollution could pose risks to human health too. The findings highlight the need for better regulations to limit phthalate pollution in our environment.
