Pollution of molluscicide and concentration in organs.

我们从菲律宾的宿务、马尼拉和达沃采集了以下15个水样：A，宿务市的深井水; B，宿务市的稻田水; C，宿务市港口的海水; D，宿务市的河水; E，宿务市的自来水; F，甲米地省甲米地市的稻田水（马尼拉附近）; G，拉古纳省稻田水（马尼拉附近）; H，布拉坎省巴伦苏埃拉镇稻田水（马尼拉以北）; I，大马尼拉马卡蒂市自来水; J，大马尼拉帕西格市帕西格河水; K为大马尼拉帕赛市港口海水; L为北达沃省帕那博镇稻田水; M为达沃市班克罗汉河水; N为达沃市自来水; O为达沃省明塔尔镇稻田水; P为达沃市港口海水。其中3个海水样本因渗透压较高而未能进行测试。因此，我们总共使用了13个样本。 ...更多信息 本研究采用气相色谱-质谱联用技术测定了22种农药在水体中的残留量：1、西玛津、2、噻苯威、3、异丙威、4、仲丁威、5、克百威、6、二嗪农、7、马拉硫磷、8、依地芬磷、9、丁草胺、10、三氟氯氰菊酯、11、氟氯氰菊酯、12、氯氰菊酯、13、14、15、16、17、18、19、13、溴氰菊酯;结果显示，所有水质样本中的农药浓度均未超过日本的容许限量（每升0.001至0.0003毫克）。然而，在宿务市的深井水中检测到0.0007 kg/l的稻瘟灵（容许限度：0.001 kg/l）等农药，但其含量低于容许限度值。需要进一步研究，在更多地点的水样中重复检测更多种类的农药，以便我们对菲律宾水体中残留农药的存在做出实质性结论。少

We collected the following fifteen water samples from Cebu, Manila and Davao in the Philippines : A, deep well water in Cebu City, B, rice field water in Cebu City ; C, sea water from the port in Cebu City ; D, river water in Cebu City ; E, tap water in Cebu City ; F, rice field water in Cavite City, Cavite Province (near Manila) ; G, rice field water in Laguna Province (near Manila) ; H, rice field water in Valenzuela Town, Bulacan Province (north from Manila) ; I, tap water in Makati City, Metro Manila ; J, Pasig River water in Pasig City, Metro Manila ; K, sea water from the port in Pasay City, Metro Manila ; L, rice field water in Panabo Town, Davao North Province ; M, Bankerohan River water in Davao City ; N, tap water in Davao City ; O, rice field water in Mintal Town, Davao Province ; P, sea water from the port in Davao City. Among these, the three sea water samples could not be tested because of their high osmotic pressure. Therefore, we used in total the thirteen samples.In th … More e present study, we measured by using CG-MS the amounts of the following twenty-two pesticides in the water samples : 1, Simazine ; 2, Thiobencarb ; 3, Isoprocarb (MIPC) ; 4, Fenobucarb (BPMC) ; 5, Carbofuran ; 6, Diazinon ; 7, Malathion ; 8, Ediphenfos ; 9, Butachlor ; 10, Cyhalothrin ; 11, Cyfluthrin ; 12, Cypermethrin ; 13, Deltamethrin ; 14, Phenthoate (PAP) ; 15, Fenitrothion ; 16, Oxadiazon ; 17, Carbaryl (NAC) ; 18, Pencycuron ; 19, Mepronil ; 20, Propyzamide ; 21, Iprobenfos ; 22, Isoprothiolane.None of the pesticide concentration in the water samples was found to be more than the Japanese tolerance limit values (0.001-0.0003 mg/1). However, some pesticides, for example, Isoprothiolane (the tolerance limit : 0.001 kg/1) at 0.0007 kg/1 in the deep well water in Cebu City, were detected, though their amounts were less than the tolerance limit values. Further studies to detect more kinds of pesticides repetitively in the water samples from more sites are needed, in order for us to make a substantial conclusion on the presence of residual pesticides in the bodies of water of the Philippines.
