1. Environmental Chemical Pollution and Health:THE COST OF INACTIONRiana BornmanEnvironmental Chemical Pollution & Health; UP Centre for Sustainable Malaria Control, SHSPH

2. Conflict of interest statementOpinions expressed and conclusions arrived at are those of myself, and are not necessarily to be attributed to any funder. I declare I have no actual or potential competing financial interests.As scientist I declare that I am not bound by any Government, International Government Organization, Lobby Group, or NGO position or policy on chemicals.The papers I refer to here are published in international, peer reviewed journals.

3. Definition of EDCs (IPCS 2002)An endocrine disruptor is defined as, “…an exogenous substance or mixture that altersfunction(s) of the endocrine system and consequently causes adverse health effects in an intact organism, or its progeny, or (sub) populations.”3estrogen, androgen and thyroid hormone

5. Characteristics of EDC: implications for developmental exposures hormone levels, receptors, physiological responses change intensely across the life cycleappropriate levels hormones during early development – fetus and infantdisorders of sexual development e.g. abnormal androgen or estrogen levels5

6. Characteristics of EDC: implications for developmental exposures Exposures exogenous compounds (EDCs) can mimic or antagonize hormonal systems and change the developmental trajectoryDepending on timing of exposure, nature of the EDC, and its levels, an adverse outcome may be evident at birth, or there may be a latent disease outcome Developmental Origins of Health and Disease (DOHaD): motivates latent effects of EDCs on every endocrine system studied to date6

11. EDC-2: Endocrine Society's CONCLUSIONS Endocrine-disrupting Chemicalsthorough coverage studies developmental exposures EDCs, especially fetus and infantcritical life stages: perturbations of hormones can increase probability of disease or dysfunction later in lifefuller understanding of endocrine principles by which EDCs act:including non-monotonic dose-responseslow-dose effectsdevelopmental vulnerabilityhealthcare providers to translate the science of endocrine disruption to improve public health.11Andrea C Gore et al., 2015

12. Significance of policyCost of brominated flame retardants likely to be higher in the US, as use is more stringently limited in Europe.Levels of phthalates (DEHP) have decreased 17-37% in the US between 2001-10 and costs of attributable disease are likely to have decreased over that period.EDCs are used globally, and findings support careful regulation as part of the Strategic Approach to International Chemicals Management. 12

13. 13Quantifying EDC disease burden and costsFor EDCs, laboratory evidence is supplemented by varying levels of epidemiologic evidenceEach condition is clearly multifactorial.Absent estimates of the burden of disease and disability potentially produced by EDC exposures, high costs of alternatives are likely to outweigh concerns about the health consequences of using EDCs.Expert panels quantified EDC disease burden and costs

14. 14J Clin Endocrinol Metab 100: 1245–1255, 2015The objective was to quantify a range of health and economic costs that can be reasonably attributed to EDC exposures in the European Union (EU).

15. 15J Clin Endocrinol Metab 100: 1245–1255, 2015EDC exposures EU are likely contribute substantially to disease and dysfunction across the life course with costs in the hundreds of billions of Euros per year. These estimates represent only those EDCs with the highest probability of causation; a broader analysis would have produced greater estimates of burden of disease and costs.

16. Pesticides used in agricultural and homes13 million lost IQ points in each EU country  €124 billion lost earning potential59,300 born each year with intellectual disability = additional €21.4 billion1,555 obese 10 year olds = €24.6 million28,200 50–64 year olds with diabetes = €835 million16Bellanger et al, Legler et al J Clin Endo Metab epub Mar 5 2015

17. Phthalates used in food wraps, cosmetics, shampoos, vinyl flooring 24,800 additional deaths 55 – 64 year old men = €7.96 billion lost economic productivity618,000 additional assisted reproductive technology procedures costing €4.71 billion53,900 50-64 year old women obese = €15.6B20,500 50-64 year old women diabetic = €607M17Hauser et al, Legler et al J Clin Endo Metab epub Mar 5 2015

25. CONFIDENTIAL25Much higher developing countries and countries with economies in transition

26. STATUS QUO: EDCs IN AFRICALack of awareness and knowledge amongst government officials & general public Competition national resources/priorities Lack of easily accessible, user-friendly informationMost countries no monitoring chemical movementNo information of chemicals in products - industry not expected to divulge information; no tracking chemicals from production or import to secondary use and final disposal.26

27. Industry often not required to do rigorous risk assessment on chemicals as a prerequisite before introducing them into the marketFragmented policy approach to dealing with chemicals management in generalExcept in RSA, no research or activities are known to have been undertaken on EDCs in Africa.27STATUS QUO: EDCs IN AFRICA
