Seawater Quality Testing

Marine pollution usually refers to the damage to the marine ecosystem caused by humans changing the original state of the ocean. Pollution caused by harmful substances entering the marine environment can damage biological resources, endanger human health, hinder fishing and other human activities at sea, damage the quality of seawater and environmental quality, etc. In order to prevent and control seawater pollution, protect marine biological resources and other marine resources, contribute to the sustainable use of marine resources, maintain the marine ecological balance, and protect human health.

Factors Causing Seawater Pollution

The main substances that cause seawater pollution are sewage, waste residue, waste oil and various chemical substances. The main causes are:

1. Pollution caused by ships, mainly manifested as follows

(1) ship operation pollution sources;

(2) marine accident pollution sources;

(3) ship dumping pollution sources.

2. Marine pollution caused by marine oil development, mainly in the following ways

(1) Domestic waste, production waste and oily sewage discharged into the sea;

(2) Accidents such as accidental oil spills, oil overflows and well blowouts;

(3) Waste and oily sewage from man-made processes and natural processes flowing into the ocean.

3. The pollution of the ocean from land-based factories is mainly manifested in the discharge of sewage into the ocean from chemical plants on both sides of the rivers connected to the sea, as well as industrial waste and household garbage containing pollutants dumped on the river banks or rivers, which enter the ocean with the river or the rising and falling currents.
