One of the key responsibilities of chemical pigment manufacturers is to develop pigments that are safe, non-toxic, and environmentally friendly. Today, there is a growing demand for greener and more sustainable products, and chemical pigment manufacturers need to keep up with these trends by using eco-friendly raw materials and production processes. This includes reducing the use of harmful chemicals and promoting recycling and waste management practices.

Zhu et al. were the first to provide evidence that TiO2 NPs (21 nm) can transfer from daphnia to zebrafish by dietary exposure. Hence, dietary intake could be a major route of exposure to NPs for high trophic level aquatic organisms. Ecological research should therefore focus, not only on the concentration of NPs in the environment, but also on its bioconcentration, bioaccumulation and biomagnification. In addition it has been shown that TiO2 NPs can increase accumulation of other environmental toxicants: enhanced accumulation of cadmium (Cd) and arsenic (As) was found in carp in the presence of TiO2 NPs. The strong adsorption capacity for Cd and As was explained by the large specific surface area and strong electrostatic attraction of TiO2 NPs that contribute to facilitated transport into different organs.
