environmental concerns

waste water

high concentrations of triclocarban may found in wastewater. among top ten commonly detected organic wastewater compounds in terms of frequency , concentration. triclocarban has been found in increasing concentrations on past 5 years , more detected triclosan.

wildlife toxicity

triclocarban has hazard quotient rating of greater one. hazard quotients greater 1 indicate potential adverse effects on organisms due toxicity. triclocarban found in high concentrations in aquatic environments, there concerns regarding toxicity aquatic species. specifically, triclocarban has been shown toxic amphibians, fish, invertebrates, , aquatic plants, , traces of compound have been found in atlantic dolphins. antibacterial components of triclocarban may disrupt hormones critical developmental , endocrine processes in exposed animal wildlife. neurological , reproductive systems particularly affected through contact compound. triclocarban may affect animal wildlife behavior. example, triclosan , triclocarban 100-1,000 times more effective in inhibiting , killing algae, crustaceans , fish in killing microbes. triclocarban , triclosan have been observed in multiple organisms, including algae, aquatic blackworms, fish, , dolphins.

bioaccumulation

triclocarban bioaccumulation possible in number of organisms. earthworms known store chemical in bodies and, because of ecological role food source, have potential move triclocarban food chain. microbial species found in soils bioaccumulate triclocarban. however, health of these microbes has not been found affected presence of chemical. triclocarban rapidly accumulated in both algae , adult caged snails. moreover, triclocarban more triclosan bioaccumulate in aquatic organisms.

bioaccumulation occur in plants treated water containing triclocarban. however, estimated less 0.5% of acceptable daily intake of triclocarban humans represented vegetable consumption. thus, concentration of triclocarban in edible portions of plants negligible exposure pathway humans.

the potential triclocarban bioaccumulate in plants has been exploited in construction of wetlands meant remove triclocarban wastewater. these constructed wetlands considered cost-effective treatment option removal of ppcps, including triclocarban , triclosan, domestic water effluent. such compounds tend concentrate in roots of wetland plants. potential ecological risks associated method decrease of root systems in wetland plants, reduced nutrient uptake, decreased competitive ability, , increased potential uprooting. due these risks, long term exposure of wetland ecosystems wastewater containing triclocarban major solution wastewater pollution still under discussion.
