PrintedinTheNetherlands. v Preface The Society of Environmental Geochemistry and Health (SEGH) Fifth International Conference on Arsenic Exposure and Health Effects was held July 14 to 18, 2002 in San Diego, California. Both public and private groups sponsored the conference. In additiontoSEGHandtheUniversityofColoradoatDenver,othersponsorsincludedthe US Environmental Protection Agency (US EPA), the Centers for Disease Control and Prevention (CDC), AWWA Research Foundation (AwwaRF), the Electric Power Research Institute(EPRI),andtheNationalInstituteofEnvironmentalHealthSciences(NIEHS). Over 220 people, including the speakers and poster presenters, attended the 5th conference. Of these, approximately one-third were non-US citizens; the largest groups were from Asia and Europe. The attendees included scientists from academia, industry, local,state,USfederalandseveralforeigngovernments.Thedisciplinesofgeochemistry, chemistry, molecular biology, biochemistry, epidemiology and medicine were well- represented at the meeting. Several outstanding papers and posters presented at the conferencegeneratedlivelydiscussionanddebate,notonlyaboutscientificissues,butalso social, public policy and regulatory issues. The interactions between the attendees both duringandoutsidethesessionsresultedinmanynewcontactsbetweenscientists. Therewere14platformsessionsand4postersessionswith67speakersand130posters. Panel discussions were held after each session to encourage discussion and debate. Two sessionsweredevotedtoanoverviewofsomeUSEPAandNIEHSarsenicprograms.As in past conferences, the first report of elevated arsenic exposures in a new country was given. This time it was Nepal; Dr. Shrestha reported elevated arsenic concentrations in groundwatersintheTerairegion. Theseedsoftheconference(s)weresownatameetingoftheSEGHExecutiveBoardin December1991.TheyagreedtoformanArsenicTaskForcesimilartotheSEGHLeadinSoil Task Force that had been formed in the 1980s. It was clear that there was a growing controversyregardingtheproposedchangesintheUSEPAMaximumContaminantLevel (MCL)forarsenicindrinkingwater.Thisistheenforceablestandardfordrinkingwater.In additiontoimpactingonwaterutilities,thedevelopmentofthestandardwouldalsohave thepossibilityforsignificanteconomicimpactsonthecleanupofsuperfundsitesandon theelectricpowerindustry(becauseofarsenicinflyash). The Task Force was formed in 1992 and co-chaired by Willard Chappell and Charles Abernathy.Aninternationalconferenceseemedtobeanexcellentwaytobegintocompile thedataandtodeterminewhatneededtobedoneinthisarea.TheFirstSEGHInternational ConferenceonArsenicExposureandHealthEffectswasheldinNewOrleansinJuly,1993. Thisconferencewassuccessfulinattractingthetoparsenicresearchersintheworld.Itwas followedbytheWorkshoponEpidemiologyandPhysiologically-BasedPharmacokinetics thatwasheldinAnnapolis,MDinJune,1994.Perhapsthemostsignificantoutcomeofthe 1994 Workshop was the realization that there are many arsenic hot spots in the world. Althoughnotwidelyrecognizedbythescientificcommunityatthattime,significantpublic healthproblemsexistedincountriessuchasIndia,ThailandandChina.TheSecondSEGH International Conference on Arsenic Exposure and Health Effects was held in June, 1995 inSanDiegowithaprimarypurposebeingtohighlighttheglobalaspectsoftheproblem vi Preface andmostoftheimpactedcountrieswererepresented.Atthattime,thebiggestrecognized problemareawasinWestBengal,Indiawhereanestimated30millionpeopleareatrisk fromarsenicexposureinthegroundwater. TheThirdSEGHInternationalConferenceonArsenicExposureandHealthEffects(July, 1998) was also held in San Diego and continued the theme of global impact of arsenic. In addition, two new countries with significant arsenic problems, Inner Mongolia and Bangladesh were represented. The attendees were to learn that the Bangladesh problem couldbelargerthantheoneinWestBengalwithapossible80millionpeople(two-thirdsof thepopulation)atrisk.Thissituationcaughttheattentionofthemedialaterin1998withthe publication of a front-page article in the Nov. 16, 1998 New York Times. The article was syndicatedandpublishedinnewspapersaroundtheworld. The SEGH Fourth International Conference on Arsenic Exposure and Health Effects (June,2000)continuedthefocusontheglobalimpactofarsenic,andalsofeaturedsessions on mechanisms of cancer carcinogenesis, metabolism, and water treatment technology. NewimpactedcountriesrepresentedincludedVietNam. TheFifthInternationalConferenceonArsenicExposureandHealthEffects(July,2002) introduced the participants to the problems in Nepal. Numerous speakers discussed advances in understanding the mechanisms of arsenic toxicity and carcinogenicity. The considerable advances in several areas were readily apparent and this monograph representsthestateoftheart.Theorganizersaredeeplygratefultotheauthorsfortheirfine workandtothesponsorsforthesupportthatmadeitpossible. We are also deeply appreciative of the fine efforts of Rosemary Wormington of the EnvironmentalSciencesProgramoftheUniversityofColoradoatDenverwhoputinlong hours as conference coordinator. She kept the entire Conference going and, more than anyoneelse,isresponsibleforthesuccessofthisandthepastconferences. vii Contents Preface. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . v ListofContributors. . . . . . . . . . . . . . . . . . . . . . . . . . . . . xi I.
