Conclusion

Much historical research implicates older chemicals such as PCBs and DDT in causing adverse effects and hormone disruption in wildlife.  Even though these chemicals are now banned, we should not conclude that we are in the clear because these chemicals will be lingering with us for many years to come.

Additionally, many newer, current-use chemicals with similar properties are not as well researched as their older counterparts, and what has already been discovered is merely the tip of the iceberg. Chemical production is on the increase, global contamination is on the increase, and unprecedented and unexplained ill health or declines in numerous species across the globe are also on the increase.

Scientific research is only just beginning to catch up with the extent of the chemical threat.  

To suggest there is no link between these trends, and to give chemicals the benefit of the doubt, is reckless. To assume a link and to begin an immediate precautionary phase-out of certain chemicals with undesirable properties, in the face of unknown risks before it is too late, is prudent and necessary – because the safety of wildlife, people and the environment is paramount.

CHEM Trust’s most recent report is Effects of Pollutants on the Reproductive Health of Male Vertebrate Wildlife - Males Under Threat by Gwynne Lyons.

This report shows that male fish, amphibians, reptiles, birds and mammals have been harmed by chemicals in the environment. Widespread feminisation of male vertebrate wildlife is highlighted. These findings add to mounting worries about the role of hormone-disrupting or so-called ‘gender-bending' chemicals in the environment, and the implications for human health.
