Friends,
A friend I made along the way in crafting the Open Minds Podcast put me on to water quality. During this person’s university days, they were lectured by an interesting fellow – Professor Angus Chu, whose extensive research provide key insight into the role of chlorine in water treatment, the presence of microplastics, and the emerging concerns about endocrine-disrupting chemicals.
Professor Chu recounts the historical use of chlorine, starting from its initial application as a weapon during World War I to its current role in preventing waterborne diseases. He emphasizes that while chlorine has been crucial in safeguarding public health, it also has drawbacks. One such issue is the formation of trihalomethanes (THMs), carcinogenic compounds produced when chlorine reacts with organic matter in water. Chu notes that although Canada does not yet have strict regulations for THM limits, the potential health risks make this an area of concern for the future.
I was quite amazed at the danger with large chlorine cylinders, which, if compromised, could pose severe public health risks.
A particularly intriguing part of the discussion revolves around endocrine-disrupting chemicals (EDCs). Chu explains that EDCs can mimic natural hormones like estrogen and disrupt biological processes. He shares instances where these chemicals, originating from sources like industrial effluents and personal care products, have led to phenomena such as the feminization of fish. Chu’s insights into the presence of EDCs in sewage effluent, especially from birth control pills and other pharmaceuticals, raise important questions about the impact of these substances on both human health and ecosystems.
A separate conversation on EDCs is necessary, clearly.
