With the sounds of fireworks seemingly never-ending, and us now being in the Diwali-through-Guy-Fawkes plus <any excuse to let 'em off> period, I thought it might be appropriate to post about connections between fireworks and thyroid.

Environmental impacts of perchlorate with special reference to fireworks-a review.
Sijimol MR1, Mohan M.
Perchlorate is an inorganic anion that is used in solid rocket propellants, fireworks, munitions, signal flares, etc. The use of fireworks is identified as one of the main contributors in the increasing environmental perchlorate contamination. Although fireworks are displayed for entertainment, its environmental costs are dire. Perchlorates are also emerging as potent thyroid disruptors, and they have an impact on the ecology too. Many studies have shown that perchlorate contaminates the groundwater and the surface water, especially in the vicinity of fireworks manufacturing sites and fireworks display sites. The health and ecological impacts of perchlorate released in fireworks are yet to be fully assessed. This paper reviews fireworks as a source of perchlorate contamination and its expected adverse impacts.

This paper shows that perchlorate levels in the environment can be traced directly to firework displays.
Fireworks Displays Linked To Perchlorate Contamination In Lakes
Not to mention the people who make fireworks and those who live nearby.
Shame - they can look so pretty...
