Soil And Water Ul Testing Lab Education Biological Contamination Authority Third-party authentication service

Provide a variety of biological contamination testing items

Various biological indicators in the environment are regularly or temporarily monitored to understand the harm and impact of pollutants on organisms, so as to determine the type and degree of environmental pollution.

Through the long-term accumulation of monitoring data and trend analysis of the natural environment and polluted environment, it provides a reliable basis for the government to formulate laws and regulations, environmental quality standards, environmental quality control measures and environmental management.

Actively carry out biological monitoring technology research, promote the development of biological monitoring technology.

Product range:

Water pollution indicator organisms refer to organisms that can produce various qualitative and quantitative reactions to pollutants in water, such as plankton, epiphytes, benthic animals, fish and myrtles.
Plankton refers to the organisms suspended in the water, which can be divided into two categories: zooplankton and phytoplankton. Most of them are small, weak or have no swimming ability, and live a drifting life.
Epiphytes (i.e. periphytes) are communities of organisms attached to the surfaces of various substrates (plants, animals, stones, artificial) that have been submerged in water for a long time
Benthic organisms are macroscopic aquatic invertebrates that inhabit in the silt and rocks at the bottom of water bodies, and are attached to aquatic plants. Their body length is over 2mm, and they are also called benthic macroinvertebrates.
In clean rivers, lakes and ponds, the content of organic matter is small, and there are many microorganisms. However, after being polluted by organic matter, the number of microorganisms increases greatly, so the number of microorganisms in water can reflect the degree of water pollution by organic matter.

Service project:

1. Testing standard (part)

Unpolluted environmental water bodies have a wide variety of aquatic life, which is the result of long-term natural development and a sign that the ecosystem remains relatively balanced. When the water is polluted, the community structure and the number of aquatic organisms will change, which will destroy the natural ecological balance system. The final result is the extinction of sensitive organisms, the vigorous growth of resistant organisms, and the single community structure, which is the theoretical basis of the biomes monitoring method.

2. Certification services

The test report issued by Global Zhongyi has legal effect and can be used in scenarios such as the entry of supermarkets, product appeals, anti-malicious rights protection, and auctions (appeals and auctions must meet Party A's testing requirements).
