一組聯合國團隊在研究過中國北方吉林省松花江的石化工廠外洩事件後,於昨天發表他們的研究報告。其中指出在這場跨國界的汙染事件兩個月後,仍須投入更多的研究,才能釐清這場在這個世界最大型水系之一的意外,造成的環境及對人類健康傷害影響評估。該次爆炸意外,造成估計約100公噸的有毒化學物質如苯、苯胺及硝基苯流入松花江,使得水表濃度超出中國水質標準。
聯合國環境計畫(UNEP)四人評估小組,係應中國國家環境保護總局之邀,於2005年12月10日至16日訪視中國,協助評估及減輕污染的散逸。在其建議中,UNEP的調查小組表示,對事故現場的環境衝擊,包括任何有可能的地下水或地表水來源、土壤污染、空氣污染都應確認、減緩,且要盡快實施污染清除的工作。
報告中並建議中國化學工廠施行抽樣風險評估,以改進安全相關措施、降低意外發生機率以及加強災害發生後的控管。
此次事件的善後工作中,中國及俄羅斯政府間的合作和協調層級均達至層級,根據中國和俄羅斯簽署的松花江水質聯合應變檢測計畫,兩國都將加強聯合監測水質。
Two months after the Songhua River transboundary chemical spill, one of the largest in a river system anywhere in the world, more study is needed to determine its environmental and human health effects, a United Nations team has concluded. The team issued its report Thursday, after studying the effects of an explosion that occurred in November at a petrochemical plant in China's northern Jilin Province.
The explosion resulted in spill of an estimated 100 metric tons of the toxic chemicals benzene, aniline and nitrobenzene into the Songhua River, with surface water concentrations exceeding the surface water levels permissible in China.
The four person team from the United Nations Environment Programme (UNEP) visited China from December 10 to 16, 2005 at the invitation of the Chinese State Environmental Protection Administration (SEPA) to help with assessment and mitigation of the spill. In its recommendations, the UNEP team says environmental impacts on the site of the accident, including any potential sources of groundwater, surface water and soil contamination and air pollution should be identified and mitigation and decontamination measures implemented as a matter of urgency.
The report recommends the consideration of a risk assessment of a random sample of Chinese chemical factories in order to strengthen safety related procedures, to minimize the risk of accidents and the improved handling of accidents if they do occur.
The cooperation and coordination between China and Russia over the incident has reached the highest level of both governments. On the basis of the Joint Emergency Response Monitoring Plan on Water Quality of the Songhua River signed between China and Russia, both countries will strengthen joint monitoring.
