Sediment analysis3 General3.1 Representative sampling Purports to collect a representative sample should be well-designed sampling section sampling stations to monitor waters, sampling time, sampling frequency and sample The number of products, so that the data samples were analyzed objectively characterize the real situation of the marine environment, to ensure that the sampled product not only represents the original environment, and And should not change in the sampling process, not add, not losses. 3.2 Sampling target Sampling goal is to collect easy to transport, easy to handle laboratory, the samples can be characterized overall environment. Take practical measures to make the sample Its in the marine environment is the same ratios and concentrations of the relevant component, the component does not change before laboratory analysis, sampling of the same holding status. 3.3 Sampling Program Sampling plan is an important part of the monitoring plan. Generally they include. --- Where and how the samples; --- Sampling equipment and calibration; --- Sample container, including cleaning, fixing agent; --- Scotia take samples; --- Sample pretreatment procedures; --- Decimation procedures; --- Sample record; --- Sample storage and transportation; --- Quality assurance and quality control measures. 3.4 Sample Program In designing the sampling program, first determine the purpose and principles of sampling, sampling purpose is to determine the sampling locations, sampling frequency, sampling time, like The main basis for the sampling and analysis procedures for processing of technical requirements include. --- Determine sampling purposes and principles; --- Determine sample collection time and space scales; --- Set of sampling points; --- Field sampling methods and quality assurance measures. 3.5 Regulatory sample Supervision of the sample, that sample collected from the integrity of the sample collection to analysis, the sample analysis should be traceable; sample letters Bar scene Notepad, regulatory records and sample inventory, and procedures used have specific requirements; for the different stages of the sample custodian level Responsibility, sampling person responsible for site monitoring, transfer of per capita clear responsibilities.4 Water Samples4.1 General provisions Obtain a representative sample from the marine environment, and to take all precautions to avoid transition occurs during the time interval sampling and analysis Technology, is the first key to the investigation and monitoring of the marine environment. Sampling program should include the following aspects. --- Sample Objective. the purpose of the sampling is usually divided into environmental quality control, environmental quality characterization and identification of three types of pollution; --- Sample collection time and space scales; --- Set of sampling points; --- Field sampling methods and quality assurance measures. 4.2 Safety Measures Sample collection should take the following safety measures. --- Sampling in all weather conditions, should ensure the safety of operating personnel and equipment; --- Over a large area of water sampling, the operator should wear a seatbelt, ready life buoy, all kinds of equipment should be securely fastened to take Measures; --- Before the ice-covered bodies of water samples should carefully check the location and extent of ice; --- Surveillance ship in waters all sampling to prevent merchant ships, fishing boats and other vessels close and be ready to use a variety of signals indicate is Nature of the work; --- Avoid dangerous shore sampling and other unsafe locations. If unavoidable, not a single person, a group of people can be sampled and Take corresponding measures. If qualified, should be sampled at the bridges, docks and other safe locations. Sampling installed on the shore or in shallow waters Equipment, protective measures should be taken; --- Sampling, should take special precautions to avoid some fortuitous circumstances arise, such as corrosive, toxic, flammable and explosive, and viruses Harmful animals harm the human body; --- Use electrically operated sampling equipment, operation and maintenance process, to strengthen security measures. 4.3 Sample 4.3.1 Sample Type 4.3.1.1 instantaneous sample Instantaneous sample is discontinuous samples. Both in the water and the bottom surface or at a predetermined depth, the general should be collected by hand, in some cases Under the automatic method can also be collected. Pollution monitoring or investigating the degree of pollution waters investigate a range of possible, especially in the larger scope of the sample shall be collected Instantaneous samples. For some test items, such as oxygen, hydrogen sulfide and other gases dissolved in the water sample, the sample should be collected instantaneously. 4.3.1.2 Continuous samples Continuous samples typically comprises, at fixed intervals samples capturing timing (depending on the time) and the collection flow rate set at a fixed interval The sample (depending on volume). Continuous samples were collected directly into commonly used at sea outfalls and other special circumstances, in order to reveal the use of instantaneous sample observation Not change. 4.3.1.3 mixed sample Mixed sample is a sample point at the same flow rate, time, volume-based hybrid of several separate parts of the sample. Mixed samples To provide an average data on the components. If the sample of the analyte in the acquisition and storage of process changes significantly, you can not use mixed water sample, to single Only collect and save. 4.3.1.4 Integrated water samples The sampling points at the same time from different water samples were obtained by mixing the water sample (time is not exactly the same, but as close as possible). 4.3.2 Requirements of the sample Once the sample is collected after, when the sampling should be kept the same state. Avoid sample collection, storage and analysis of the testing process from being Hull, water harvesting equipment, laboratory equipment, glassware, chemicals, air and operator itself produce contamination. Sample analyte Also be due to adsorption, volatilization settlement or suffer losses. 4.4 Optimization of sampling temporal frequency Determined based on the temporal and frequency selection sampling positions, first objective analysis of the large amount of historical data, the survey monitoring sea Domain characteristics Division. Zoning is the key feature of central tendency for each station and the historical data to determine the characteristics of zoning standards. Depending on the relative uniformity of the spatial and temporal characteristics of pollutants in the larger area of the uneven distribution of the waters and the local waters, using homogeneous analysis Classification methods, fuzzy set cluster analysis, etc., will monitor the polluted waters into the transition zone and the control zone. 4.5 Layout of sampling stations 4.5.1 Layout Principles Monitoring stations and monitoring sections of the layout should be determined according to the monitoring plan for monitoring projects, combined with the type of waters, hydrology, meteorology, environment and other natural Characteristics and source distribution of the factors put forward a comprehensive program to optimize distribution, determined on the basis of the research and demonstration. The main site of sampling should be combined Reasonably laid waters significant change in environmental quality or important functional use, such as near a major source of pollution in coastal or estuary. In the sea Early pollution investigation domain can be meshed distribution. Many factors affect the layout of the site, follow the following principles. --- Can provide representative information; --- Site surroundings geographical conditions; --- Dynamic market conditions (current and wind fields); --- Socio-economic characteristics and impact of regional sources of pollution; --- Safety of navigation around the site; ---Economic Benefit Analysis; --- Try to consider the site in the geographical distribution uniformity, and try to avoid the division of the system boundary features; --- According to hydrological characteristics, water features, water self-purification capacity of the environment factors such differences, consider the layout of monitoring sites. Also Taking into account the natural geographical diversity and special needs. Monitoring section 4.5.2 Monitoring sections should follow the layout of coastal dense, more sparse far shore, the focus area (such as river mouths, sewage outlets, fisheries or farms, scenic, travel ) More dense, more sparse control area principle laid district, the port terminals. Section shall be set according to actual needs to master the water environment quality situation, consider spatial and temporal distribution and variation of pollutants controlled, to With fewer sections and measuring points to obtain a representative sample of the best. A section can be divided into left, center, right and at different depths, following the adoption of the measured water quality parameters, do variance analysis between each measuring point, judge Significant differences. At the same time analysis to determine how closely each measuring point, which determines the position of the sample point within the section. To determine the exact mix The number of sampling points on the cross section area is necessary to specify the minimum correlation coefficient between sampling points. Sampling along the ocean can be set on the coast Large cross section, and a plurality of sample points in the section. Sampling section estuaries zone should be laid perpendicular to the direction of the runoff diffusion. According to the terrain and hydrodynamic characteristics laid one to several sections. Harbour sampling section (station) depending on terrain, tides, waterways and the object and so laid. In the current complex region, with sampling section Shoreline vertically. Sampling stations open sea coast of vertical and horizontal cross-section grid was laid. Large sections may be provided in the ocean along the coast. 4.5.3 Sampling level Sampling levels are shown in Table 1. Table 1 Sample Hierarchy Depth Range / Standard level The bottom layer and the adjacent standard minimum distance / Less than 10 surface 10 to the surface 25, bottom 25 to the surface 50, 10m, bottom 50 to the surface 100, 10m, 50m, bottom 5 100 surface, 10m, 50m, as appropriate, the following aqueous layer plus layer, the bottom 10 Note 1. The surface of the sea means less 0.1m ~ 1m; Note 2. the bottom of the harbor and estuary waters to take the best from the seabed in the aqueous layer 2m can increase the distance from the bottom of the deep sea or, where appropriate, when large waves. 4.6 sampling time and sampling frequency According to the following requirements determine the sampling time and sampling frequency. a) determining the principles of sampling time and frequency are as follows. --- With minimal effort to meet the environmental information to reflect the required information; --- Technically possible and feasible; --- Can truly reflect the variation of environmental factors; --- Try to consider the continuity of the sampling time. b) spectral analysis can be used as a method for determining the sampling time and frequency, according to the wealth of information drawn pollutants into the sea becomes Curve, changes in expectations or higher is desirable to determine the maximum sampling time and sampling frequency. c) the use of multi-year survey monitoring information to the appropriate parameters as a statistical indicators, time clustering analysis. Clustering results based on time Determine the sampling time and sampling frequency. You can also use other statistical methods, statistical tests, and to determine the sampling And frequency. Note. for environmental quality control sampling frequency should generally be higher than the quality of the environment to characterize the desired sampling frequency. Identification of pollution sources and environmental quality control sampling procedures System, the quality of the environment to characterize the different procedures, to determine the influence of a lot of sampling time and sampling frequency factor, high sampling frequency than the frequency of pollutants occur More. 4.7 The sampling device Technical Requirements 4.7.1 Water sampler Following is a water sampler main technical requirements. --- Having a good charge injection and tightness for. sampler structure should be tight, shut down the system reliable, and not susceptible to blockage, water sampling Bottle of water should be fully exchanged rapidly. Parts should be reduced to a minimum; --- Material to corrosion-resistant, non-staining, non absorbent.
