The risk of drinking water is greatly concerned because of the large amount of pesticide applied to paddy field and the contamination of drinking water sources due to the runoff. A mathematical model is developed, based on the mass balance, to predict the fate of paddy field pesticides from application, runoff and mixing in a river, taking account of the physical chemical properties and processes of volatilization, degradation, adsorption and desorption. The model is applied to a river basin in japan.to estimate the contaminant level of several popularly used pesticides at the water intakes. The health risk in drinking water induced by each pesticide concerned is estimated and evaluated by comparing with the acceptable daily intake values(ADI) and with that induced by trihalomethanes. An index to evaluate the total risk of all pesticides appearing in water is proposed. The methods for risk management are also discussed.

Objective The custom-homebuilding company, Cosmic Garden Co. Ltd., located in okayama City, {1.was established in 1.97 and uses specific natural ore powder （SNOP） in wall materials and surveys customers in order to improve allergic symptoms. Methods To investigate the biological effects of SNOP, patients with a pollen allergy were recruited to stay in a room surrounded by cloth containing SNOP （CCSNOP）, and their symptoms and various biological parameters were compared with those of individuals staying in a room surrounded by control non-woven cloth （NWC）. each stay lasted 60 min. Before and immediately after the stay, a questionnaire regarding allergic symptoms, as well as POMS （Profile of Mood Status） and blood sampling, was performed. Post-stay minus pre-stay values were calculated and compared between CCSNOP and NWC groups. Results Results indicated that some symptoms, such as nasal obstruction and lacrimation, improved, and POMS evaluation showed that patients were calmer following a stay in CCSNOP. Relative eosinophils, non-specific Ig e, epidermal growth factor, monocyte chemotactic protein-I, and tumor necrosis factor-a increased following a stay in CCSNOP. Conclusion This ore powder improved allergic symptoms, and long-term monitoring involving 1.to 2 months may be necessary to fully explore the biological and physical effects of SNOP on allergic patients.
