The Minamata Convention¡ªnamed for a Japanese city where mercury poisoning injured or killed thousands of people¡ª mandates the phase-out of mercury in some batteries, fluorescent lamps, cosmetics, and medical devices by 2020. ³ÖÐøÕûÍíµÄ»áÒé¹ýºó£¬À´×Ô140¸ö¹ú¼ÒµÄ´ú±íÔÚ1ÔÂ19ºÅ¾ÍÏÞÖÆ¹¯ÎÛȾ´ï³ÉÁËÒ»Ö£¬ÀúÊ·4ÄêµÄ̸ÅÐÖÕÓÚ´ïµ½ÁËÖյ㡣¡¶Ë®Ù¶¹²Ô¼¡·¡ªÒÔ·¢ÉúÖÂʹÊýǧÈËÉËÍö¹¯Öж¾Ê¹ʵÄÈÕ±¾Ë®Ù¶ÊÐÃüÃû¡ªÒªÇóÔÚ2020Äê֮ǰÖð²½Í£Ö¹Ê¹Óú¬¹¯µç³Ø£¬ÈÕ¹âµÆ£¬»¯×±Æ·ºÍÒ½ÁÆÆ÷е¡£ It sets limits on mercury emissions from coal-fired power plants, waste incineration, and cement factories. Countries with small-scale gold mining must devise strategies to reduce or eliminate mercury use. The treaty allows the use of mercury as a vaccine preservative. ¡¶Ë®Ù¶¹²Ô¼¡·»¹¹æ¶¨ÁË»ðÁ¦·¢µç³§£¬À¬»ø·ÙÉÕ³§ºÍË®Äà³§µÄ¹¯ÅÅ·ÅÉÏÏÞ¡£Ä³Ð©ÔËÐÐС¹æÄ£½ð¿óµÄ¹ú¼Ò»¹±ØÐëÖÆ¶¨³öÏàÓ¦µÄ¹æ»®À´¼õÉÙ»òÕßÈ¡µÞ¹¯µÄʹÓ᣸ù«Ô¼ÔÊÐí°Ñ¹¯ÓÃ×÷ÒßÃç·À¸¯¼Á¡£ The Zero Mercury Working Group called the treaty a step forward but said controls on the two largest sources of pollution¡ªcoal-fired power plants and small-scale gold mining¡ªwere disappointingly weak.
