New mercury(汞) threat to oceans from climate change

    Rising temperatures could boost mercury levels in fish by up to seven times the current rates, said Swedish researchers in an article published in Science Journal. They've discovered warming increases levels of the toxin (毒素) in sea creatures. In experiments, they found that extra rainfall drives up the amount of organic material flowing into the seas. This alters the food chain, adding another layer of complex organisms which boosts the concentrations of mercury up the line.

    Mercury is one of the world's most toxic metals, and according to the World Health Organization, is one of the top ten threats to public health. The substance at high levels has been linked to damage to the nervous system, paralysis and mental impairment in children.

    The most common form of exposure to mercury is by eating fish containing methylmercury(甲基水银), an organic form of the chemical which forms when bacteria react with mercury in water, soil or plants. Levels of mercury in the world's ecosystems have increased by between 200% and 500%, since the industrial revolution say experts, driven up by the use of fossil fuels such as coal.

    In recent years there have been concentrated efforts to limit the amount of mercury entering the environment, with an international treaty, called the Minamata Convention, signed by 136 countries in place since 2013.

Researchers hope that the Minamata treaty will be successful and countries reduce the amount of mercury that is being produced. Otherwise this discovery of a previously unknown source could have impacts for human health.

    Other researchers in the field say that the new study highlights important issues that have previously been little known.

     “This work experimentally proves that climate change will have a significant effect of methylmercury budgets in coastal waters and its accumulation in fish,” said Milena Horvat from the Jozef Stefan Institute in Slovenia.

     “This work will also help us understand the formation of mercury in fish and help reduce mercury from emission sources (primarily industrial).”

    Our summer vacation begins on July 15th and lasts nearly two months. Considering that my brain needs rest after a period of hard work, I, together with my family, went to our countryside, a very small farmhouse in which my grandparents used to live, to spend the summer. Obviously, life in the country is very different from that in the city.

    Early in the morning I took a walk along the field side. The air was fresh and pure. With a dog following, sometimes I ran a race in the meadows covered with tall grass. Sometimes I climbed up the hill to see the sun slowly yet steadily rise from the eastern horizon. The birds also sang restlessly among the bushes. In order to appreciate the quietness of the country, I gave myself entirely to nature, with a light heart and a happy mind.

    Sometimes in the afternoon I, together with my cousins, took a rod and went to the river to fish. It made the family happy when they saw me returning with a basketful of large fresh fish. When night came, I would sit at the door and tell the most wonderful and interesting stories to my cousins, who listened to the tale of wonder with open eyes and mouth.

    I wish I could enjoy such calm, pure and beautiful rural life forever.

    Have you ever been afraid to talk back when you were treated unfairly? Have you ever bought something just because the salesman talked you into it? Many people are afraid to speak out for their rights. Dr Robert Albert, author of Stand Up, Speak Out, and Talk Back thinks it's because their self-respect is low.

    But Albert and other scientists are doing something to help people help themselves. They offer "assertiveness training" courses A. T. for short. In the A. T. Course people learn that they have a right to be themselves. They learn to speak out and feel good about doing so. They learn to help themselves without hurting other people.

In one way, learning to speak out is to get rid of fear, a group taking an A. T. Course will help the shy person to lose his fear. But a. T. uses an even stronger motive— he needs to share. The shy person speaks out in the group because he wants to tell how he feels. Whether or not you speak up for yourself depends on your self-respect. If someone you face is more "important" than you, you may feel less of a person. You start to doubt your answers to problems. You can get to feel good about yourself. And once you do you can learn to speak out.
