It is striking that many substances have a high bioaccumulation potential and have proven to be persistent in the degradation tests carried out. Such substances can accumulate in fish. This is shown by measurements from a bathing lake in Germany. If substances are not metabolized or excreted by organisms, they can accumulate via the food chain and ultimately cause damage to predators at the top of the food chain, such as the otter or fish-eating birds.

The data show, firstly, that some of the UV filters frequently used today have a considerable potential for environmental hazards and, secondly, that for individual substances the data available is too limited to allow an assessment to be made.

Consumer Safety Committee (SCCS). 13,14 In addition, avobenzone has been identified by the EU Scientific Committee as a non Estrogens that could affect human health by the EU Scientific Committee on Cosmetic Products and Non-Food Products (SCCNFP).15 Independent non-governmental organizations such as the Environmental Working Group (EWG) have also reviewed existing human exposure data and Toxicity data for avobenzone and have concluded that toxicity is low and there are no Hormone disruption associated with this ingredient.
