S6E12 Final Episode: The Missing Exit

Every molecule of the modern world was designed to enter, almost none were designed to leave. In the final episode of the Chemistry season, we step back from the individual stories and name the pattern behind them all: we taught chemistry to perform, but never to depart. Why "just ban it" keeps failing, what the chemicals quietly leaving our blood prove about exits that actually work, and why chemistry still has no receipt the way carbon does.

S6E11 One Barrel

A barrel of oil is just 159 litres and a price until chemistry gets involved. Most of the barrel burns as fuel. A few litres become the materials modern life runs on: medicine, phones, packaging, even wind turbine blades. This episode is about that transformation and the bill that comes with it.

S6E10 PFAS: The Chemistry That Refused to Break

Most chemicals eventually degrade. PFAS were designed not to. This episode starts with the carbon–fluorine bond, why chemists built molecules that nature can barely break, where that stability still looks essential, and what modern chemistry is learning from the trade-off.

S6E9 Persistent Organic Pollutants: The Chemicals That Outlived Their Purpose

DDT was banned in 1972. PCBs in 1979. Yet in 2026, there are still fish you shouldn't eat from the Hudson River, and polar bears carrying chemical loads from factories thousands of kilometers away. What happens when a chemical outlives the problem it was built to solve.

S6E8 Dioxins: When Chemistry Creates What Nobody Wanted

What happens when a chemical reaction creates something nobody asked for, and it takes 50 years to clean up? The strange history of dioxins, and why they're still the reference case for how the world regulates persistent pollutants today.

S6E7 Byproducts: The Hidden Chemistry of Everything

Every factory on Earth makes two things: the product on the label, and everything the reaction leaves behind. Sulfur, red mud, CO2, phosphogypsum, this is the hidden economy of industrial leftovers, and why some of it built fortunes while some of it built disasters.

S6E6 Green Chemistry

For a century, pollution was cleaned up after the fact. Green chemistry asks if it can be designed out before production even starts. From a diabetes drug redesigned to cut 80% of its waste to a plastics plant recycling 100 million pounds a year, this is where that bet has already paid off, and where it hasn't yet.

S6E5 Chemistry Behind Beauty

Every bottle of shampoo, jar of cream, and can of spray leaves something behind, in the water, in the soil, in the body. From a billion-dollar baby powder verdict to a spray can that quietly failed its own safety test, this episode asks what beauty's biggest brands aren't telling you.

S6E4 Chemistry Behind Healthcare

Medicine saves millions of lives every day. So why is it quietly becoming one of the hardest pollution problems on the planet? Traces of nearly 1,000 different medicines now turn up in rivers across 89 countries, and in our soil, our food, even the air. Once a drug leaves the body, whose job is it to clean up?

S6E3 Chemistry Behind Food

Food is usually described by protein, fat, and calories. Almost never by the chemistry that made it possible. The Chemistry Behind Food follows that journey from field to storage, processing, packaging, and trade. Nature Food, Cambridge research, sesame recalls, fipronil eggs, and Indian basmati residues. What chemical history did your meal carry before it reached you?
