The fate and transport of pretilachlor, one of the most widely used rice-paddy herbicides in Japan, were monitored in a rice paddy plot for 28 days after its application in the five study years. The effect of the percolation rate on herbicide loss was investigated. The concentration of pretilachlor in the paddy water was at its highest level within 2 days of application. The maximum concentration in percolated water was lower, and it was reached 1 or 2 days later than that in the paddy water. Almost all the pretilachlor loss was caused by percolation. The pretilachlor loss, as estimated from the amount that was applied and the cumulative percolation loss, ranged from 7.4 to 16.3%. In the five study years, the average percolation rate for the 7 days following application ranged from 11.5 to 29.3 mm/day. The pretilachlor loss increased proportionally with the percolation rate for 7 days following application. (c) Pesticide Science Society of Japan

The purpose of this study is to evaluate the effect of subsurface water flow on herbicide residues in stream water. Pesticide concentrations and loads were monitored three times in Yasu River and twice in Hino River from May to June 2005. Surface water always flowed and reached to river mouth in Hino River, although infiltration of all of the surface water was observed in some part of the Yasu River channel. Pesticide concentrations returned to the surface streams were < 1/100 lower than that of surface water before infiltration. Possible reason may be the dilution and diffusion with shallow ground water and/or lake water. Runoff coefficient at the end of receiving stream was calculated to 1.0 for Hino River and 0.01 - 0.1 for Yasu River.

The effects of reducing fertilizer and non-puddled cultivation on outflow loads from paddy fields, water purification and mass balance were examined for four years. Four experimental plots were set up for comparison. <BR>As a result, the levels of surface effluent loads of the plots with single application of fertilizer in nursery box were reduced 64 % for T-N and 51 % for T-P as compared with the plots that used conventional fertilizer. The reduced level of subsurface effluent loads of the plots were 26 % for D-N and 23 % for D-P. SS, COD, T-N and T-P surface runoff loads from the non-puddled divisions were reduced 71 %, 59 %, 41 %, and 48 % respectively as compared with those of the puddled divisions. For water purification, non-puddled cultivation appeared to be effective in reducing the effluent loads, because there were significant differences in SS, COD, and P. Additionally, interaction between the puddling methods and fertilizing methods showed significant differences in N. Both nitrogen and phosphorous collected from incoming factors such as irrigation, rain and fertilizer were greater than those of outgoing factors such as surface effluent load, subsurface effluent load and hulled rice because of the use of too much fertilizer.

Herbicide Discharge from Paddy Fields Located Around Lake Biwa Basin and Development of Simple Model for Estimation of Herbicide Loss Reviewed

The concentrations and loadings of herbicides were investigated in paddy fields (40.5ha) located around Lake Biwa from May to October in 2005 and 2006. The herbicide losses from the basin determined from the cumulative load from May to July and the application amount determined by the questionnaire method by Japan Agricultural Cooperatives (JA) were estimated in 2005 and 2006, respectively, to be 26.3% and 36.5% for Daimuron, 24.5% and 30.8% for Bomobutide, 21.5% and 18.6% for Simetryn, 15.7% and 9.30% for Benfresate, 9.14% and 11.3% for Pretilachlor, 5.49% and 5.33% for Mefenacet, and 0.32% and 0.84% for Esprocarb, and in 2005 to be 5.52% for Thenylchlor and 4.74% for Cafenstrol. A Simple model was developed to estimate herbicide losses by multiple regression analysis. The specific loss, which is calculated from the total loss and the average discharge on nonrainy days, was used as the criterion variable. The water solubility, Henry's law constant and soil adsorption constant were used as explanatory variables. The most important contributor to herbicide losses is the adsorption constant of soil. The specific losses calculated from the result of multiple regression analysis were consistent with the observed values. The errors between the observed and calculated values were within ± 0.5% for four herbicides and almost ± 1.0% for five herbicides.

In order to find an alleviation method for the adverse effect of environmental endocrine disrupters, we studied the effects of the putative endocrine disrupter and peroxisome proliferator, di(2-ethylhexyl)phthalate (DEHP), on animal growth and vitamin metabolism. It is known that the effects of chemical compounds such as xenobiotics differ according to the dietary protein source. We compared the effects of dietary DEHP administration on rats fed with a diet containing milk casein or wheat gluten. The increased conversion ratio of tryptophan to nicotinamide by DEHP administration was significantly higher in the casein group than in the gluten group. We also investigated the effects of DEHP on the urinary excretion of other vitamins. DEHP administration resulted in decreased urinary excretion of vitamin B-1, vitamin B-2, and pantothenic acid.
