8 Toxic Pollutants In the Clean Water Act Section 307(a)(1) 65 Entries Some Entries include whole families 8

9 Priority Pollutants 126 Priority Pollutants This was a litigated / negotiated list Only included pollutants having developed analytical test methods Not necessarily the worst Appendix A to 40 CFR 423 Steam Electric Power Generating 9

10 What about other chemicals? About 80,000 new chemical compounds are developed every year What do we know about them? 10

11 Things we didn t know we had to worry about : Emerging Pollutants 11

12 Emerging Pollutants Contaminants Substances of Concern EPOCs POPs NanoMats ECOC s HAA s ESOC OWC s PPCP PIEs PhACs EDC Nanoparticles EMC Microconstituents

More Appropriately Termed Emerging Substances of Concern Not all of these substances can accurately be described as contaminants or pollutants Some of these substances are found naturally in our

13 More Appropriately Termed Emerging Substances of Concern Not all of these substances can accurately be described as contaminants or pollutants Some of these substances are found naturally in our surface waters Others are natural substances that are concentrated by anthropogenic activities And still others are man-made chemicals that do not occur in nature D.M. Smith, University of Denver Estradiol PBDE

14 Things we didn t know we had to worry about : Perfumes and Fragrances Why do plants make these chemicals? How do plants make these chemicals? 14

15 know we had to worry about : Perfumesand fragrances 15

26 Things we didn t know we had to worry about : Emerging Pollutants Pharmaceutical metabolites Estrogen mimics Nanoparticles 26

27 Nanoparticles NanoMats Fullerenes (a.k.a. buckyballs) Nanotubes Graphenes Quantum dots Nanopowders (metal oxides) Natural particles (e.g., soot)

28 Nanoparticles Natural and manmade structures in the 1 to 100 nm size range Used in nanotherapeutic pharmaceuticals, drug delivery, cosmetics, energy storage products, fabrics, lubricants, even golf balls Potential use in contaminated site clean up

29 Nanoparticles Toxicity of most nanotechnology products has not been determined Potential mechanisms of aquatic toxicity from the particles themselves are Ingestion Physical disruption Gill irritation

41 Bromine Compounds PBDEs Poly-brominated diphenyl ethers Flame retardants added to wide variety of household and consumer products Are not covalently bound to substrate to which they are applied, so they are easy to liberate

42 PBDEs Non-point and point source issue Primarily released to atmosphere not water Crustaceans very sensitive to PBDEs. as low as 1.2 µg/l Global transportation of released PBDEs and other organic contaminants (increasing concentrations in polar bears) Potential (currently unknown) effects from PBDDs and PBDFs;

43 PBDE Effects Toxic to Adult Mammals Endocrine Modulator Thyroid Estrogen/anti-androgen Developmental and Reproductive effects Penta/Octa BDE 99 Delayed puberty, sex organ changes, decreased sperm counts Neurotoxic Penta/BDE47, 99, 203, 206 Deficits in sensory, motor, and cognitive function Toxicity
