Technical field
The present invention relates to scientific investigation ship technical field, more particularly to a kind of sea surface water continuous sampling system.
Background technology
Micro- plastics are a kind of plastic grain of the diameter less than 5 millimeters, are a kind of main carriers polluted.Micro- plastics
Including polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyurethane, polyamide, polyethylene terephthalate etc..Micro- plastics
Small, this means that (specific surface area refers to surface possessed by porosu solid substance unit mass to higher specific surface area
Product), specific surface area is bigger, and the ability of the pollutant of absorption is stronger.First, a large amount of Polychlorinated biphenyls, double is had existed in environment
(these organic pollutions are often hydrophobic to the persistence organic pollutants such as phenol A, that is they are less susceptible to be dissolved in water
In, so they tend not to arbitrarily flow with flow), once micro- plastics and these pollutants meet, just aggregation is formed
One organic contamination sphere.Micro- plastics are equivalent to the saddle horse as pollutant, and the two can bat around in the environment.
《Environment affixes one's name to yearbook in 2014》With《Assess the value of plastics》Report points out that plastic pollution has threatened marine organisms
Existence and tourist industry, fishery and business development.Cause attention of the people to micro- plastics.
The grain size for the micro- plastics gone around is generally within 5mm, it is easy to be dwelt life by the zooplankter in marine environment, bottom
Object, fish, mussel etc. " low side " food chain biology is eaten by mistake, and micro- plastics cannot be digested, in vivo can only be in stomach by biology intake
In always exist, take up space, cause animals got sick even dead;And it is eaten if it is with micro- plastics of organic pollution
Fall, that is even more to make the matter worse for the injury of these planktonic organisms, and pollutant releases under the action of enzyme in vivo, adds
Its acute state of an illness.On the one hand it is likely to result in the death of biology, ecosystem stabilization is influenced, on the other hand may pass through food
Chain is propagated, on the dining table for finally appearing in the mankind.The biology that mussel, zooplankter etc. are in food chain bottom end can be by upper layer animal
It eats up, and micro- plastics or even micro- plastics and organic pollution all enter in the animal body of upper layer, one feature of food chain is " rich
Collection " effect, perhaps harmful substance only has 1% in bathyshere body, but has reformed into 20% to upper layer, can make so a large amount of
Eat micro- plastics biology it is sick or dead, the biology on the top of food chain is the mankind, and the mankind are under the action of enrichment, meeting
In vivo, these are difficult to the little particle digested and generate unpredicted harm to people a large amount of micro- plastics of accumulation.Micro- plastics like
PM2.5 in ocean is general, threatens marine organisms and the health of the mankind.Zoopery find plastic particles due to grain size compared with
It is small, histocyte can be entered, accumulated in animal viscera, cause inflammatory reaction, lead to hepatic injury and endocrine disturbance etc..
Micro- plastics in ocean are carried out with management and control, the first step be will the ingredient of plastics and content be examined slightly to this
It surveys, to judge the seriousness and main source of pollution, foundation is provided to the improvement of next step.At present to the micro- modeling in ocean
The detection of material particle has PerkinElmer infrared spectrums and infrared microscopy imaging system, transformation micro ft-ir spectroscopy method etc..

Artificially fixed, easy to cause to damage with hull generation friction, shock, the method for trawlnet is easy and immersed body winding, such as supports
Area or some floating materials are grown, it equally can not long-time stable sampling.The side of scientific investigation ship continuous sampling during walking boat at present
Method, it is usually upper on the quarter that one or more sampling pipes are installed, sampling pipe is stretched into 20~30cm of the seawater water surface or less, passes through pumping
Wetting system is collected the surface seawater of the position on ship by sampling pipe, but this method of sampling there are problems that, and first,
Scientific investigation ship in navigation there is certain speed, sampling pipe can be caused by the lasting resistance of seawater when acquiring surface seawater
Sampling pipe generates upward buoyancy, can not only influence the underwater position of sampling pipe, and sampling pipe on the quarter on be difficult to fix;
Second, even if traditional sampling pipe is firmly fixed on the quarter, cause seawater generation to hold since scientific investigation captain's phase persistently navigates by water
