Environmental free radicals are indicators of environmental pollution

What are free radicals?

Free radicals are mainly produced by pollution in the environment and cause abnormal conditions produced by normal substances. For example, oxygen (O2) in the environment is converted to superoxide radicals (O2-) due to pollution. The free radicals in the environment are constantly generated, and at the same time they are continuously neutralized and disappeared. The net value of the generation and disappearance is "environmental free radicals".

Free radicals may be continuously generated due to various pollution (air pollution, water pollution), microorganisms (bacteria, fungi), radiation (ultraviolet rays) and the high temperature of the internal combustion engine of automobiles.

Free radicals will cause harm?

Numerous scientific journals have reported that free radicals can harm the organism's immune and genetic systems. Therefore, the damage caused by free radicals has four characteristics:

First, the indefinite etiology (indefinitely): Owing to the damage to immune system, the causes to the death of aquaculture are hard to be identified.

Second, hereditary (hereditary): DNA damage & gene mutation, which leads to the fragile & feebler spawns.

Third, degenerative: Indirect injury results in the delay of the death which is observed after the rain.

Fourth, the irrrparable (irrrparable): Hereditary and immune cells are hard to repair once damaged. That is, recurring of diseases happens easily after injury.

Free Radical Detector (FRD)

Principle

Detect the concentration of free radicals by using the phenomenon that the fluorescent substance reacts with free radicals to increase the brightness。

How to use??

Mix 50 cc of pool water with the free radical detection ingot for 5 minutes, then filter the mixed solution (filter paper pore size 0.45 μm), and finally irradiate the filtered solution with ultraviolet light (365 nm) for colorimetric conversion.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Free Radicals Detector(FRD) can predict water quality changes in advance

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Free Radicals Detector(FRD) can provide complete water quality information for the ponds.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Free Radicals Detector(FRD) can adjust the amount of biological agents used.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Free Radicals Detector(FRD) can understand the damage of rainwater to aquaculture ponds.

(The concentration of free radicals in rainwater is about 6 to 15 times that of aquaculture ponds)
