与日俱增,举世关注的污染问题,需要尽快制定一些指标,用以定量及定性的评价其污染的程度。关于油和盐类对土壤和水的污染,应通过必要的试验来确定。此项待后详述。多少年来,石油工业造成的污染,比其本身所受到的污染危害更为严重。直到最近,舆论和出版界有权威的评论都认为,不管是直接的还是间接的,其主要的污染源都与石油业有关。事实上,石油工业比其它工业较早地认识和做出了很大的努力,以防止污染。在油井附近,原油和污水的污染,凭肉眼就可看到。因此,保护土地、防止这种污染乃是常事。然而,经验告诉我们,由于没有早期公布与水质有关的报告,此事经常发 The ever-increasing and world-wide concern of pollution requires the development of some indicators as soon as possible to quantitatively and qualitatively assess the degree of pollution. Pollution of soils and water by oil and salts should be determined by the necessary tests. This item will be described in detail later. For years, the pollution caused by the oil industry has harmed even more than the pollution itself. Until recently, there was an authoritative commentary in the media and in the publishing world that all major sources of pollution, whether direct or indirect, were related to the oil industry. In fact, the oil industry recognized and made a great effort earlier than other industries to prevent pollution. Near the well, crude oil and sewage pollution, with the naked eye can see. Therefore, it is not uncommon to protect the land and prevent it. However, experience tells us that in the absence of early publication of water quality-related reports,
