Abstract [en]

The risk assessment process and the subsequent risk management measures need tobe constantly evaluated, updated and improved. This thesis contributes to that workby considering, and suggesting improvements, regarding aspects like userfriendliness,transparency, accuracy, consistency, data reporting, data selection anddata evaluation.The first paper in this thesis reports from an empirical investigation of themotivations, intentions and expectations underlying the development andimplementation of a voluntary industry owned environmental classification systemfor pharmaceuticals. The results show that the purpose of the classification systemis to provide information, no other risk reduction measures are aimed for.The second paper reports from an evaluation of the accuracy and the consistency ofthe environmental risk assessments conducted within the classification system. Theresults show that the guideline recommendations were not followed in several casesand consequently alternative risk ratios could be determined for six of the 36pharmaceutical substances selected for evaluation in this study. When additionaldata from the open scientific literature was included the risk ratio was altered formore than one-third of the risk assessments. Seven of the 36 substances wereassessed and classified by more than one risk assessor. In two of the seven cases,different producers classified the same substance into different classificationcategories.The third paper addresses the question whether non-standard ecotoxicity data couldbe used systematically in environmental risk assessments of pharmaceuticals. Fourdifferent evaluation methods were used to evaluate nine non-standard studies. Theevaluation result from the different methods varied at surprisingly high rate and theevaluation of the non-standard data concluded that the reliability of the data wasgenerally low.

2012 (English)Doctoral thesis, comprehensive summary (Other academic)
Abstract [en]

A complex process like risk assessment and the subsequent risk management decision makingshould be regularly evaluated, in order to assess the need to improve its workings. In this thesisthree related matters are addressed: evaluation of environmental risk management strategies,evaluation of environmental risk assessments, and how ecotoxicity data from the open scientificliterature can be used in a systematic way in regulatory risk assessments. It has resulted in thefollowing: a publically available database with ecotoxicity data for pharmaceuticals (Paper I); anevaluation and review of the Swedish Environmental Classification and Information System forpharmaceuticals (Papers II and III); a comparison of current reliability evaluation methods and areliability evaluation of ecotoxicity data (Paper IV); and an improved reliability and relevancereporting and evaluation scheme (Paper V).There are three overall conclusions from this thesis:(1) Ecotoxicity data from the open scientific literature is not used to the extent it could be inregulatory risk assessment of chemicals. Major reasons for this are that regulators prefer standarddata and that research studies in the open scientific literature can be reported in a way that affectstheir reliability and the user-friendliness. To enable the use of available data more efficiently actionsmust be taken by researchers, editors, and regulators. A more structured reliability and relevanceevaluation is needed to reach the goal of transparent, robust and predictable risk assessments.(2) A risk assessment is the result of the selected data and the selected methods used in theprocess. Therefore a transparent procedure, with clear justifications of choices made, is necessaryto enable external review. The risk assessments conducted within the Swedish EnvironmentalClassification and Information System for pharmaceuticals vary in their transparency and choice ofmethod. This could come to affect the credibility of the system since risk assessments are notalways consistent and guidelines are not always followed.(3) The Swedish Environmental Classification and Information System for pharmaceuticalscontribute, in its current form, to data availability and transparency but not to risk reduction. Thesystem has contributed to the general discussion about pharmaceuticals’ effect on the environmentand made data publicly available. However, to be an effective risk reduction tool this is not sufficient.
