项目摘要

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.

我们从菲律宾宿雾市、马尼拉市和达沃市采集了以下十五个水样：A、宿雾市深井水，B、宿雾市稻田水；C、宿雾市港口海水；宿务市的自来水；F 甲美地省稻田水（马尼拉附近）；H 巴伦苏埃拉镇稻田水；布拉干省（马尼拉以北）；I，马尼拉大都会马卡蒂市的自来水；J，马尼拉大都会巴石市的巴石河水；K，马尼拉大都会帕赛市的海水；北达沃省Panabo镇；M，达沃市Bankerohan河水；N，达沃市自来水；O，达沃省Mintal镇稻田水；P，达沃市港口海水；其中，达沃市的三个海水样本由于渗透压较高而无法进行测试，因此我们总共使用了 13 个样本。在本研究中，我们使用 CG-MS 测量了其中的含量。水样中含有以下二十二种农药： 1、西玛津； 3、异丙威（MIPC）； 5、克百威（BPMC）； ; 6, 苯硫磷; 9, 氯氟氰菊酯; 12, 溴氰菊酯; 15, 杀螟松; 17、西维因 (NAC) 18，戊菌隆； ; 19, 灭螨灵; 21, 异丙苯硫灵; 22, 异丙硫灵。未发现水样中的农药浓度超过日本的容许限值（0.001-0.0003 mg/1）。某些农药，例如异丙硫戊环（容许限度：0.001 kg/1）为0.0007在宿务市的深井水中检测到了 1.0 kg/1 的农药，但其含量低于容许限值，因此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，以便我们能够做到这一点。对菲律宾水体中残留农药的存在做出实质性结论。
