Description

China's immediate offshore area priority pollutants register is determined method

Technical field

The present invention relates to a kind of China immediate offshore area priority pollutants register and determine method.

Background technology

Along with the whole world to the understanding of marine pollution and the development of marine environment science research and resist technology; many countries have all taked the measure of preventing and remedying pollution of strong ocean; with regard to chemicals in the marine environment pollute control; the level difference of various countries' development; the national conditions difference; the pollution situation difference; the specific practice of preventing and remedying pollution has difference more; but any is arranged is common; Here it is: because toxic pollutant is numerous; no matter, can not all formulate standard to each pollutant for which type of control purpose; limiting emissions all; all carry out control, and can only be therefrom to select some priority pollutants pointedly to be controlled.That is to say, must determine a screening principle (although the principle that each country works out may be different), numerous pollutants are carried out the classification queuing, therefrom filter out potential danger big as controlling object, the a control of proposition list, this screening process are exactly mathematical preferential process, we call the marine environment priority pollutant to the pollutant of preferential selection, abbreviate priority pollutant (Priorty Pollutants) as.Monitoring and control that priority pollutant in the marine environment is carried out are called preferential monitoring in ocean and control.

At present, many in the world countries have all issued environment priority pollutants list, relatively these lists can find that they have following characteristics mostly: output is big, recall rate is high, be difficult to degraded, certain residual level is arranged in environment, have biological accumulation, three cause effect or toxicity, health and ecologic environment are constituted potential threat.Undoubtedly, the toxic pollutant that people pay close attention to the most possesses the toxic chemical substance of these characteristics just, also is the pollutant of emphasis control certainly.It is worthy of note that along with the development and the progress of science and technology of producing, marine site or sea area priority pollutants list may change.At certain phase, limited by various factors, the pollutant list of preferential control can only reflect production and scientific technological advance level at that time.The restriction of simultaneously also contaminated thing improvement technology and pollutant monitoring, analysis, measuring technology.

Summary of the invention

The present invention is in order to solve existing in prior technology the problems referred to above, a kind of science, accurate to be provided, can containing effectively in China's immediate offshore area environment, human body are endangered comparatively definite method of severe pollutant register.

Concrete solution of the present invention is: a kind of China immediate offshore area priority pollutants register is determined method, it is characterized in that: carry out according to following steps:

A. according to the discharging list of China's nearshore marine environment pollution surveys and data, sewage draining exit monitoring, external various priority pollutants,, determine priority pollutants primary election inventory in conjunction with the emission behaviour of China's all contaminations;

B. set up priority pollutants screening and assessment system, by methods such as setting up assessment indicator system, formulate standards of grading, the assignment screening factor and index weight are determined fixed priority pollutants primary election material is marked, sorted, to filter out several or tens kinds of preferential control materials;

C. investigate the monitoring and the control feasibility of each material in the above-mentioned preferential control list;

D. determine the priority pollutants list.

The present invention compares with prior art, has following advantage:

Used for reference the priority pollutants list of countries in the world, and in conjunction with the actual conditions of China's immediate offshore area, spatial-temporal distribution characteristic and Changing Pattern according to part marine site each key element of thalassochemistry beyond my domestic water, territorial waters and the territorial waters, in conjunction with immediate offshore area chemical contamination situation and dynamic law, the environmental pressure index is carried out analysis-by-synthesis, determine that finally China preferentially controls chemical pollutant register inventory in the offshore sea waters; This part list suits the marine site situation of China most, concentration based on pollutant in the marine environment, with the bio-toxicity is that evaluating has been set up priority pollutants quantitative screening pattern and method system, taken into full account in the actual environment pollution condition and the relation between the issuable biological effect, and combine current China pollution situation and real work situation, determine China's offshore sea waters priority pollutants, can strengthen the specific aim of China's offshore sea waters pollutant monitoring and evaluation, for marine environmental protection provides certain technical support; And this priority pollutant screen body cording has opening, is applicable to dynamically updating of the novel pollutant that may occur future and priority pollutants register.
