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.

我们从菲律宾的宿雾，马尼拉和达沃收集了以下15种水样：宿雾市的A深水，B，宿雾市的稻田水； C，宿雾市港口的海水； D，宿雾市的河水； E，宿雾市的自来水； F，卡维特省卡维特市（马尼拉附近）的稻田水； G，拉古纳省（马尼拉附近）的稻田水； H，布拉坎省瓦伦苏埃拉镇（马尼拉北部）的稻田水；我，马尼拉大都会马卡蒂市的自来水； J，马尼拉大都会帕西格市的帕西格河水； K，马尼拉大都会帕赛市港口的海水； L，达沃北省帕纳波镇的稻田水； M，达沃市的Bankerohan河水； n，达沃市的自来水； o，达沃省Mintal镇的稻田水； P，达沃市港口的海水。其中，由于它们的渗透压很高，因此无法测试三个海水样品。因此，我们在总共13个样品中使用了。在本研究中，我们通过使用CG-MS测量了水样中以下22种农药的量：1，Simazine； 2，thiobencarb; 3，Isroparb（MIPC）; 4，fenobucarb（BPMC）; 5，Carbofuran； 6，Diazinon； 7，Malathion； 8，Ediphenfos； 9，丁勒； 10，西哈拉瑟林； 11，Cyfluthrin； 12，cypermethrin; 13，三分之一； 14，腓骨（PAP）； 15，菲尼托翁； 16，奥卡迪亚Zon； 17，Carbaryl（NAC）； 18，Pencycuron； 19，Mepronil； 20，丙烯酰胺； 21，iProbenfos； 22，Isoprothiolane。发现水样中的农药浓度没有超过日本公差极限值（0.001-0.0003 mg/1）。但是，在宿雾市的深井水中，某些农药在0.0007 kg/1处被检测到0.0007 kg/1，尽管其量小于公差极限值，但在0.0007 kg/1处被检测到。需要进一步的研究，以从更多地点的水样中重复地检测更多种类的农药，以便我们就菲律宾水体中存在残留的农药做出实质性结论。较少的
