摘要
在北海进行的抽样调查测量了由于油罐清理作业而从化学品罐车排放入海的某些化学品的浓度。结果表明，这些化学物质的浓度非常低，比其96 h LC50值低很多倍。测量的浓度与根据北海的估计输入和周转时间计算的浓度具有相似的数量级。结论是，由于《73/78防污公约》附则II的实施应进一步减少排放入海的化学品数量，因此似乎没有必要为附则II的目的将北海宣布为一个特别区域。
Concentrations of chemicals in the North Sea arising from discharges from chemical tankers
A sampling survey in the North Sea has measured the concentrations of certain chemicals which are discharged into the sea from chemical tankers as a result of tank cleaning operations. The results obtained show that the concentrations of these chemicals are very low and many times less than their 96-h LC50 values. The measured concentrations are of a similar order of magnitude as those calculated from a procedure based on estimated inputs and the turn-over time of the North Sea. It is concluded that because the implementation of Annex II of MARPOL 73/78 should further reduce the amount of chemicals discharged into the sea it does not appear to be necessary for the North Sea to be declared a Special Area for the purposes of Annex II.
