Environmental Monitoring or Environmental Testing? Don't Mix It Up



What is the difference between environmental monitoring and environmental testing? Let's get to know.

Small partners working in the field of environment always hear about the two concepts of environmental monitoring and environmental monitoring. Although they often appear, there are still some small partners who are not clear about the two concepts and often confuse the meaning of the two concepts. Today, I will help you figure out the difference between environmental monitoring and environmental monitoring?


1. Definition

Environmental monitoring: It refers to the process of measuring the concentration of pollutants in the environment intermittently or continuously, observing and analyzing their changes and impacts on the environment. Objective: To accurately, timely and comprehensively reflect the current situation and development trend of environmental quality, and provide scientific basis for environmental management, pollution source control, environmental planning, etc. The process of environmental monitoring is divided into: task acceptance, on-site investigation and data collection, monitoring plan design, optimized distribution, sample collection, sample transportation and storage, sample pretreatment, analysis and testing, data processing, comprehensive evaluation, etc.

Environmental detection: It refers to the inspection and testing of certain environment, pollution sources and pollutants. Purpose: to meet the entrustment needs of the parties, or to meet certain commercial purposes. In many cases, environmental testing is manifested in the identification and inspection of the nature, quantity, concentration and nature of pollutants and pollution sources. For example, the measurement of concentration and type of pollutants in domestic wastewater, indoor comprehensive environment, and sulfur dioxide concentration in waste gas.


2. Difference and connection

Environmental monitoring is a legal act and a continuous and dynamic process.

Environmental testing (generally) is a business activity and a single process.


3. Differences in report contents

Contents of environmental test report:

(1) Title (such as "test report", "calibration certificate" or "sampling report");
(2) Name and address of the laboratory;
(3) Locations where laboratory activities are carried out, including customer facilities, locations other than fixed laboratory facilities, and relevant temporary or mobile facilities;
(4) Mark all parts of the report as the unique identification of a part of the complete report, as well as a clear identification indicating the end of the report;
(5) Customer's name and contact information;
(6) Identification of methods used;
(7) Description, clear identification and state of articles when necessary;
(8) The receiving date of the tested or calibrated articles, and the sampling date that is critical to the effectiveness and application of the results;
(9) Date of laboratory activities;
(10) Release date of the report;
(11) Sampling plans and methods used by laboratories or other institutions, if relevant to the effectiveness or application of results;
(12) The statement that the results are only related to the tested, calibrated or sampled articles;
(13) Results, where appropriate, with units of measurement;
(14) Supplement, deviation or deletion of methods;
(15) Identification of report approver;
(16) Clearly identify when the results come from external suppliers.


Contents of environmental monitoring report:

(1) Report title and other signs:

Monitoring nature (entrustment, supervision, etc.);
The name, address, contact information and preparation time of the report preparation unit, the location of the sampling (monitoring) site (if necessary), the name, address and contact information of the entrusting unit or the inspected unit;
Unified report number (unique sign), total pages and pages: monitoring purpose, monitoring basis (file name and number of the basis);
Sample mark: sample name, category, monitoring items and other necessary descriptions. In case of entrusted samples, the sample receiving and testing date shall be specially indicated;
If necessary, name, model and brand of sampling and analysis personnel and main instruments used for monitoring shall be listed;
Monitoring results; Report the results according to the requirements of monitoring methods, including monitoring values, measurement units and other information;
Signature and issuing date of report preparation personnel, reviewer and authorized signatory;
Monitoring the entrustment (the entrusting party, the entrusted content and the project, etc.);
If necessary, the statement that the monitoring results are only valid for samples or batches shall be indicated.


(2) When it is necessary to explain the monitoring results, the monitoring report shall also include the following information:

Deviation, addition or deletion of monitoring methods, and special monitoring conditions (such as description of environmental conditions); When the entrusting unit (or the inspected unit) has special requirements, the information of measurement uncertainty shall be included; Quality assurance and quality control: the monitoring report shall include the statistical results and conclusions of quality assurance measures and quality control data; Put forward other opinions and explanations when necessary; Additional information required by specific methods and the entrusting unit (or the inspected unit).


(3) The monitoring report including sampling results shall include the following information:

Sampling date; Name, category, nature and monitoring items of samples collected; Sampling location (attach point layout or photos if necessary); Description of sampling scheme or procedure, etc; If the environmental conditions during the sampling process (such as production conditions, operation of environmental protection facilities, conditions around the sampling point, weather conditions, etc.) may affect the monitoring results, a detailed description shall be attached; List standards or specifications related to sampling methods or procedures, as well as descriptions of deviations, additions or deletions to these specifications; If necessary, introduce the project construction, production process, pollutant generation and treatment, etc; Other information includes monitoring the quality control and quality assurance of the whole process, relevant charts and references, necessary suggestions, etc.
