heavy metals in wastewater
The so-called lowlevel radioactive waste water is a liter contained radioactivity less than 10 (-5) Curie wastewater
Easily degradable organic matter, microorganisms under natural conditions is difficult descending decomposition of organic material occurs in the natural environment can be maintained indefinitely and disseminated, and thus a serious impact on the marine environment and ecological
marine polution in China team members
1.
The lose of living environment
enclosing tideland, Marine、 coastal project and waterway dredging activities are the causes. thus, the normal activity of Marine life is Seriously interfered, sometimes even make Marine biological habitat completely extincted. And the decline in the number of mangrove is the best example.
Pathogens, infectious agents, including pathogens, disease eggs, viruses. Pathogens can survive in the water can enter the body through the food chain, which make you sick
The five wastewater discharged into the ocean
• First, the low-level radioactive waste water
The second, containing the easily degradable organic compounds and
Third, medical sewage carrying pathogens, domestic sewage and
industrial wastewater
fourth,Industrial wastewater containing organic matter and
nutrients, sewant pollution
Ocean oil leak, Marine transportation ,various landsourced pollutants (mainly coastal industrial wastewater and life sewage) discharged into the sea , aggravating the Marine environment pollution, and the Marine ecological environment has deteriorated.
3.
alien species invasion
with the development of China's ocean transportation, The spread of breeding, and soliciting, foreign Marine species' quantity increased sharply resulting in the Marine ecological system structure's imbalance, function degradation loss of diversity, whichmakes Chinese ocean environment faces increasing pressure of intrusion.
2.
overfishing and illeagally trade
because a lot of Marine animal has very high ornamental value or can be treated as art collection, and with nutritional value,people are driven by intereststo fish and even illegally catch.What's more,Marine fishing vessels increased dramatically, fishing segment has improved steadily . these cause serious destruction of the resources and even make them die out.
Wastewater containing organic and nutrient substances that contain protein, fat, amino acids, carbohydrates and other ozone-depleting organic matter and nitrogen, phosphorus and other nutrients in wastewater
