article imageMassive algae bloom attracting beach-goers in Qingdao, China

By Igor I. Solar     Jul 5, 2013 in Environment
Qingdao - Coastal areas of the Yellow Sea, located between the coast of China and the Korean peninsula, are now green as a result of the extraordinary proliferation of algae in the water. The excessive algal growth may be caused by industrial pollutants.
The unusual phenomenon covers about 28,900 square kilometers, twice the largest algae bloom on record, which occurred in this area in 2008.
This alga (Enteromorpha prolifera) is not toxic to humans, it can even be edible, but its excessive growth may lead to imbalance in the marine ecosystem by causing oxygen depletion and creating hydrogen sulphide, a toxic gas. Its unusual abundance attracts many vacationers to the beaches of Qingdao, China, who enjoy the green colored waters. However, others are stunned by the phenomenon and refuse to go into the mass of seaweed on the beach.
This species of green algae multiplies using various mechanisms which are promoted by the abundance of nutrients in the water. The current enormous proliferation is, however, attributed to the possible presence of industrial pollutants in coastal Qingdao. To help solve the problem, municipal workers are using bulldozers to remove around 7000 tons of seaweed from the beach. The authorities noted that the algae being removed from the beach will be dried and then used as fertilizer.
