Endocrine disrupting chemicals (EDCs) was detected in different part of Indonesia. It is detected in water resources, aquatic organism, and crops. EDCs were detected in the environment were organochlorine pesticides, polychlorinated biphenyls, brominated flame retardant, and heavy metals. The fact that EDCs was also detected in breast milk raised IndoWater CoP concern due to its impact on human health. PCB and organochlorine pesticides become a body burden due to their persistent feature. Half-live of PCB are 1.7-30 years, while organochlorine pesticides up to 17 years. Health impact of these compounds are the disturbance of fine motor skill, neuron development, decreasing of IQ, brain aging, and others. The impact of EDCs contamination has taken ‘real’ effect where 20% of Java barb male population developed intersexuality, where male developed testis-ova.

The fish intersexuality in Brantas river basin was an indicator for ecosystem health and ‘early warning’ system for human health. The impact of EDCs exposure on wildlife and human health is almost the same. These facts raised awareness on the health of community who consume fish from EDCs contaminated water resources. To increase public knowledge and awareness on the impact of endocrine disrupting chemicals (EDCs) on wildlife and human health, IndoWater CoP held campaign of intersexual fish in Mas river in March 8th, 2017.
