“…The highest concentration in rainwater, 0.33 µg/l was found on May 7, 2002 (sample number 34). This value was higher than previous data in Mie 11) and Kitakyushu, 12) Japan. Occurrence of dichlorvos in rainwater might be related to its vapor pressure (1.6 Pa, 20°C 13) ) and used amount (more than 1000 kg per year in Yokohama).…”

Large amounts of various pesticides have been used in farms, rice paddies and gardens. However, few studies on the pesticides in rainwater have been conducted in Japan. Thus, rainwater samples were collected from August 2001 until July 2002 at Isogo Ward of Yokohama, and 51 kinds of pesticides in the 51 samples were investigated. Although sampling point was not located in the agricultural area, dichlorvos (0.33-0.05 g/l), chlorothalonil (0.27-0.05 g/l), fenitrothion (0.24-0.05 g/l), molinate (0.12-0.05 g/l), diazinon (0.07-0.05 g/l), and malathion (0.05 g/l) were detected. Dichlorvos was the most frequently detected (65% of samples) and its highest concentration in rainwater (0.33 g/l) was found on May 7, 2002. Chlorothalonil was the second most frequently detected (33% of samples) and its highest concentration in rainwater (0.27 g/l) was found on May 26, 2002.

“…Halobenzonitrile pesticides were found in rain samples (Haraguchi et al, 1995) and in the gas phase (Pendleton and Jenks, 1984;Fujimori et al, 1991;Haraguchi et al, 1994;Hu¨skes and Palm, 1992), which are pathways for their deposition and accumulation in the aquatic environment (Waite et al, 1995). However, only a few data exist on their abiotic degradation reactions with the exception of bromoxynil.…”

“…Transport of this nature would be difficult to trace to a specific source field. The finding of pesticide residues in precipitation both within a specific agricultural region and at remote sites [8,29,30] suggests a third mode of transport (i.e., medium to long range) occurring over long periods of time. Such a transport mode could be considered non-point source in an analogous manner to contamination of water by pesticides and nutrients either across a regional or continental scale.…”

Abstract-In regions of highly diversified agriculture, herbicides used in one field may not be compatible with crops growing in nearby fields. Injury to nontarget crops may occur from drift or localized atmospheric transport of herbicide residues. Pea, bean, and corn seedlings have been used as sentinels to detect atmospheric deposition of trace residues. Seedlings were exposed at various locations throughout south central Washington and exchanged on a weekly basis with a new set of plants. Plants were returned to a lath house and observed over 3 weeks for development of symptoms indicative of probable exposure to four classes of herbicidessulfonylureas, phenoxyacetates, aminophosphonic acids, and bipyridiliniums. The most frequently observed symptoms on sentinel plants were chlorotic spots on the upper leaf surfaces; such symptoms were created under controlled conditions by exposing plants to aerosols of the sulfonylurea (SU) herbicide chlorsulfuron. For 3 years, the greatest incidence of probable SU symptoms was detected during April; however, occurrence of symptoms was not correlated with periods of maximum use of SU herbicides on wheat in the region. The results suggested a general atmospheric loading of herbicides with occasional deposition, rather than point source drift. Further tests are needed to quantitate the exposures of sentinel plants and determine if chlorotic spots are associated with adverse physiological effects.
