Analyses of the certified reference material CRM 463 showed recoveries of 96% (3.17% VC) and 92% (2.53% VC) for THg and MeHg,respectively.Results are in consonance with those of the certified values,showing the proposed method for MeHg extraction as an adequate procedure for measuring this form of Hg in the muscle of the seawater fish.The whole process is quite straight forward,with excellent recoveries while the analyses for THg and MeHg can be made in the same analytical system.
THg and MeHg concentrations in the muscle tissue of sardine,anchovy and tuna are shown in Table 2.The highest THg concentrations were observed in the following order:tuna fish,anchovy and sardine.Our data reported herein are comparable to THg concentrations in species purchased in Catalonia,Spain (Mart?-Cid et al.2007),and in European pilchard (S.pilchardus) from Tunisia and other Mediterranean regions with values ranging from 0.09 to 0.75 lg g-1 w/w (Joiris et al.1999).The mean of THg in anchovy samples analyzed in this study was is in the range of data reported by the US FDA Monitoting Program (1990–2004) with an average of 0.043 lg g-1 w/w.The maximum Hg concentration was found in the muscle tuna fish muscle probably resulting from biomagnifications within predatory species.Hg and MeHg values in tuna fish observed in this research are in the middle of the range reported by an FDA evaluation In that study,Albacore‘white’canned tuna were 0.358 versus 0.123
in the smaller‘light’tuna.The levels of mercury in the tuna
fish we analyzed were also in the range of data reported by
the US Food and Drug Administration,Monitoring Program 1990–2004(Tables 3 and 4).
Yamshita et al.(2005)have reported high Hg concen-
trations for Atlantic Bluefin Tuna,Pacific Bluefin Tuna and bigeye tuna(Thunnus obesus).The percentage of THg expressed as MeHg represented 106%±0.18%;80.39%±2.3%,and 72.66%±1.04%in tuna fish,
anchovy,and sardine,respectively.These data are in agreement with data from previous studies(Rai et al.2002;Houserova′et al.2007)suggesting that most of the Hg in fish muscle is present as MeHg.
Although all samples analyzed in this study showed Hg concentrations below the typical international marketing
limit the values for Tuna fish are higher than that reccommended by the World Health Organizations for vulnerable human consumers(WHO 1990).

祯祯：
接到你写给我们的首封来信,甚是高兴.这足以说明我家有女初长成.
祯祯,正如你所说的,在这寒冷的冬季里,你的来信带给我们无限遐想的温暖……
你是个有福的女孩,尤记得在那个狂风怒吼,大雪风飞的冬日,随着你的第一声啼哭,爸妈即肩负起了为人父母的责任.时值医院搬迁,你和许多小宝宝不慎被冻病,爸妈和你被迫在儿科滞留医治半月有余,昏迷中你与疾病抗争,爸妈时刻都守侯并牵挂着你,几经磨难,生命之神唤起了你生命的复苏；因而,你是幸运的,更是坚强的.
儿时,你就很乖,也很善解人意,常给爸爸搬凳子,给妈妈拿拖鞋,还稚嫩地唱起“世上只有妈妈好……”,让我们在工作之余,感受到你带给我们的欢愉,那熟悉的声音至今还萦绕在耳畔……
记得在你上小学一年级的那个冬天,由于爸爸工作从昌吉变动到乌鲁木齐的原因,我们幸福而温暖的家,在每周大多数的时间里,基本上只有你和妈妈相随的身影,在岁月中相伴而行,相依为生地度过了你小学的时光.
为了使你接受更好的文化教育,爸妈反复商量及征求你本人的意见,最终实现了你心目中的愿望--成为八农附中的一名学子.当你走进中学时代,令爸妈最为欣慰和感动的是,你拥有一位教学经验丰富、管理学生有方,有责任感,对学生浸注爱心的好班主任--李秀珍老师,以及各科非常优秀的代课老师.在老师们的精心指导下,你的学习有了很大的提高.比如,在语文徐老师的精心指导和反复修改下,你的作文《乳名》,不仅在华中师范大学《语文教学与研究》杂志社和中央教育科学研究所培训中心联合举办的“第八届”‘新世纪’杯全国中学生作文大赛中被评为三等奖,而且还在乌鲁木齐《都市消费晨报》“美文博览区”专栏、新疆“天山网”“校园专栏”以及“兵团新闻网”“新人新作”专栏陆续发表.初一时,语文期末的成绩也实现了质的跨跃.诚然,这些成绩的取得,也与关心和帮助过你的同学是分不开的,更是你自身辛勤努力的结果.
常言道：“少壮不努力,老大徒伤悲.”一份耕耘,一份收获.时光如白驹过溪,稍纵即逝.你的童年时代、小学时代像小鸟一样飞去无踪影；你的初二时光也不例外的会很快过去.这让我们想起你时常唱起歌曲《童年》中的“一寸光阴一寸金,老师说过寸金难买寸光阴……”的歌词.祯祯,爸妈知道你是一个很懂事的孩子,我们很欣慰有你这样一个善解人意,并且知恩图报、懂得反哺的乖女儿.然而,要知道,人的命运主要靠自己主宰,尤其是当人年轻的时候,往往就在那么“关键的几步”,而你目前正处于这个“关键”阶段,倘若把你的人生比作一座高楼大厦,而你所处的这一阶段正是这座大厦的基础,基础不牢,地动山摇,基础不牢固,不扎实,怎么能够承受荷载呢?可见,这一阶段的学习对一生的重要性,你要铭记“书山有路勤为径,学海无涯苦作舟”这句至理名言,并要以此敦促自己刻苦学习.
祯祯,你是爸妈的掌上明珠,爸妈赋予你生命,而且会将一生无私的爱都给予你,尽管这种爱的表达方式有所不同,比如：在学习上或生活上,有赞扬的、有批评的、有责备的、有肯定的,但爸妈对你的爱的目标是一致的,这就是让你永远健康、快乐、无忧、幸福的成长,正如天空对大地爱的眷恋,不仅仅表现为阳光明媚、晴空万里,还要经历舂夏秋冬的风霜雪雨,不经历风雨,怎么能见到彩虹呢?
祯祯,你在来信中谈到,你校大厅写有陶行知老先生的教育理念：“千教万教,教人求真；千学万学,学做真人.”作为父母,我们真心希望你认真按照陶老的话去做,“千里之行,始于足下.”正如你作文中写道：“不要做语言上的巨人,行动上的矮子.”学习如“逆水行舟,不进则退”,希望你能深刻领悟其意,并“三思”而践行于足下.
祯祯,正如师生对你的评价“阳光、大度”那样,在爸妈的眼里,你是一个充满活力、积极向上的好女儿.昨天,我们相携共同渡过了幸福而快乐的时光；明天我们还会迎接学习和生活等各方面的挑战,为了迎接明天的到来,让我们把握好今天,同舟共济,努力拼搏,共创美好的明天!
