中文摘要	本計畫旨在探討不同利益團體對奈米科技的風險感知。主要工作項目包括：(1) 奈米風險感知調查研究方法回顧；(2) 奈米科技風險感知問卷設計；(3) 不同利益團體風險、利益及信任感知調查及比較；(4) 探討風險感知對政府推動環境奈米計畫的政策意涵。本計畫透過文獻收集與回顧，收集目前世界各國或國際組織進行奈米風險感知研究常用的研究方法與問卷內容，並根據各方專家的建議，設計一套關於奈米科技感知的核心問卷。本計畫以此核心問卷為基礎，以電話抽樣方法（N=2,035）訪談一般民眾；以面訪（N=15）與紙筆自填問卷（N=33）方法調查奈米相關產業員工；以及透過網路調查方法（N=52）訪問奈米科技專家，藉此收集國內奈米科技感知的公眾意見。受訪者需同時評估奈米科技的風險與利益，並表達其對政府、奈米產業及媒體的信任程度。民眾、員工、專家對奈米科技的利益感知有顯著差異。有超過九成的科技專家（92.3%~98.1%）同意發展奈米科技所帶來的各種社會利益，也有超過八成的民眾（82.2%~87.9%）同意此一看法。民眾、員工、專家對奈米科技的風險感知，在「吸入」與「皮膚接觸」暴露兩方面具有顯著差異。在奈米微粒吸入風險方面，科技專家認為「非常擔心」的比例，約為民眾與員工比例的兩倍，另外有超過八成的職場員工（81.1%）擔憂皮膚接觸到奈米微粒，會造成人體健康危害。民眾、員工、專家對政府、奈米業者及媒體的信任感知也有顯著差異，且信任度普遍偏低。聽過政府管制措施的受訪者中，民眾較信任政府的奈米科技管制（47.0%），而專家對政府信任度的意見分歧。值得注意的是，大部分的受訪者「沒有」聽過政府部門有關奈米科技的管制。職場員工較信任奈米業者的產品安全保證（33.3%），而專家信任業者保證的比例不到一成（9.6%）。約三成的民眾（31.1%）信任媒體的報導，但有超過九成的專家（90.4%）對媒體沒有信心。關於奈米科技安全性的科學證據仍不足且不確定。本計畫結果也顯示，不同利益團體對奈米科技的風險、利益與信任感知，都存在極大的差異。建議政府相關部門設立預警措施，並投入更多經費支持風險感知及溝通之相關研究，避免日後產生重大風險爭議，或是健康危害。

摘要	This project is to explore the risk perceptions of nanotechnology among different stackholders. The project include: (1) collect and review the risk perception research methods; (2) design a risk perception core questionnaire; (3) investigate and compare the risk, benefit, and trust perceptions among different stakeholders; (4) explore the policy implication of public concerns about nanotechnology. We reviewed and collected research methods and questionnaires on nanotechnology risk perception in many countries or international organizations. Based on the literature review and the suggestions from experts, we designed a core questionnaire concerning the perceptions of nanotechnology. By using this core questionnaire, we conducted a telephone interview survey (N=2,035) in general population, face-to-face (N=15) and paper-and-pencil (N=33) interviews with nano-industrial workers, and a web-based survey (N=52) with nanotechnology experts to collect the public perceptions on nanotechnology in Taiwan. Participants assessed both risks and benefits associated with nanotechnology. Trusts in the authorities, nanotechnology industries, and mass media were assessed as well. The differences in the perceptions of nanotechnology among the general population, workers, and experts were significant. More than ninety percent of experts (92.3%~98.1%) and more than eighty percent of the general population (82.2%~87.9%) agreed that nanotechnology has potential benefits for society. The percentage of experts that were “very worried” about the potential risks of inhalation exposures to nanoparticles was twice as high as that of the general population and workers. More than eighty percent of workers (81.1%) worried about the adverse health effects following dermal exposures to nanoparticles. Trusts in authority regulations, nanotechnology industries, and mass media were generally low. Among the respondents ever heard of government regulations, the general population expressed more trust in government (47.0%) while the experts’ opinions were diverse. One point worthy of notice was that the majority of respondents had not heard of the regulations regarding nanotechnology. The workers had more trust in product safety certification offered by nano-industries (33.3%), yet less than ten percent of experts (9.6%) said they trust the industies’ certification. About thirty percent of the general population (31.1%) trusted the media reports, but more than ninety percent of experts (90.4%) had lost trust in media. Although the scientific evidence of the health risk of nanotechnology is incomplete and uncertain, our study indicates that the perceptions of benefit, risk, and trust of nanotechnology among the general population, workers, and experts are significantly different. Government agencies should set precaution and support more risk perception and communication studies of different stakeholders to minimize the health risks of nanotechnology.

摘要

This project is to explore the risk perceptions of nanotechnology among different stackholders. The project include: (1) collect and review the risk perception research methods; (2) design a risk perception core questionnaire; (3) investigate and compare the risk, benefit, and trust perceptions among different stakeholders; (4) explore the policy implication of public concerns about nanotechnology. We reviewed and collected research methods and questionnaires on nanotechnology risk perception in many countries or international organizations. Based on the literature review and the suggestions from experts, we designed a core questionnaire concerning the perceptions of nanotechnology. By using this core questionnaire, we conducted a telephone interview survey (N=2,035) in general population, face-to-face (N=15) and paper-and-pencil (N=33) interviews with nano-industrial workers, and a web-based survey (N=52) with nanotechnology experts to collect the public perceptions on nanotechnology in Taiwan. Participants assessed both risks and benefits associated with nanotechnology. Trusts in the authorities, nanotechnology industries, and mass media were assessed as well. The differences in the perceptions of nanotechnology among the general population, workers, and experts were significant. More than ninety percent of experts (92.3%~98.1%) and more than eighty percent of the general population (82.2%~87.9%) agreed that nanotechnology has potential benefits for society. The percentage of experts that were “very worried” about the potential risks of inhalation exposures to nanoparticles was twice as high as that of the general population and workers. More than eighty percent of workers (81.1%) worried about the adverse health effects following dermal exposures to nanoparticles. Trusts in authority regulations, nanotechnology industries, and mass media were generally low. Among the respondents ever heard of government regulations, the general population expressed more trust in government (47.0%) while the experts’ opinions were diverse. One point worthy of notice was that the majority of respondents had not heard of the regulations regarding nanotechnology. The workers had more trust in product safety certification offered by nano-industries (33.3%), yet less than ten percent of experts (9.6%) said they trust the industies’ certification.
