Risk Assessment and Monitoring for Environmental Chemicals Prachathipat Pongpinyo THAILAND

Researh and development of material in agriculture such as soil, water and fertilizer n Analysis service n Consult and certified the other laboatories n Research and study in nuclear agrochemical n Cooperate with another institute n

Purpose for attending this course Gain knowledge of Risk Assessment n Relates to my work n To know more analysis methods n

What I have studied? ? ? n n “Silent Spring” & “Our Stolen Future” Endocrine Disrupting Chemicals l l Naturally or Synthesis substances Effect to human Can change sex in some species Concentrate through the food chain

n Food Safety Calculate by Acceptable Daily Intake value (ADI) l Study of toxicity of each substances l Pesticide safety evaluation committee l Endocrine Disruptor suspected pesticide l

n Maximum Residue Limit (MRLs) l l n Good Agricultural Practice (GAP) l l l n n Related to the ADI value Set up for each pesticides Decrease the effect of pesticide Reduce the dosage volume More effective control Safety assessment of pesticide How to conserve the environment…

Dioxins, PCBs, CFC Remain in the environment for a long time n Accumulated in the body of living creature n Concentrate through the food chain n How to conserve and sustain the environment n

Registration of new pesticides Eco-toxicological effect study n Environment fate study n Ecological risk assessment toxicity exposure ratio n Study of distribution, effect and fate of man-made organic substances n

n Bio accumulation in the environment Accumulation of Organochlorines in river water and sea water l Accumulation of Organochlorines in stripped dolphin l Accumulation of Organochlorines in plankton in Osaka bay area l

Treatment of agro-chemical compounds n n n Degradation of Organophosphorus by bacteria Isolation of TCP degrading bacteria from river water and properties of bacteria Degradation of TBT by the bacteria in the river water, sea water and isolation of TBT degrading bacteria from the river water.

Solid waste management Incineration Reduce mass l Deodorization l Detoxification l Exhaust treatment is require for eliminate particulate matter such as HCl, SO 2, NO 2, dioxins and heavy metals

Alternative way to reduce dioxins Control the temperature to above 850 C n Activated carbon n Active coke reactor n Dioxin catalyst n

Consideration of waste management policy Current status of waste treatment/disposal n Responsibility of waste n Treatment and disposal technique for hazardous waste n Source of emission n

Metabolism of pesticide in plant study n n Extrapolate toxicity effect in human from animals study in vivo study use labeled compound and inject into animal Pesticide and metabolite have different toxicity properties in vitro study is for the metabolism study such as a cell culture

Soil Study Prediction half-life of pesticide n Clay type hold more pesticide than sandy soil n Leaching test; the herbicide was contained in mineral soil than volcanic ash soil n NO 3 caused a meehemoglobinemia disease n

Practice/Observation GC, GC-MS n LC, LC-MS n UV-Vis spectophotometer n Portable devices such as p. H, DO, CO 2, conductivity n AAS n

Hyogo Prefecture Technology Center on Agriculture, Forestry and Fisheries (HPTCAFF) n n n Analysis of heavy metals in soil and compost Nitrate analysis in vegetables Water quality assessment in agriculture Study of effect of pesticide on soil microbial biomass Pesticide residue analysis Rapid analysis

KOBE Quarantine Station n n Simultaneous analysis of pesticide residue in fruits and vegetables Simultaneous analysis of pesticide residue in Cereals, Beans and Seeds GC-MS for screening and fast analysis Principle of Good Laboratory Practice (GLP) Confirm the result with GC

Hyogo Prefectural Institute of Public Health and Environmental Sciences (HPIPHES) n n n PCBs ELISA kit Analysis of PCBs in sediment sample Comparison analysis of pesticide in water between SPE and LLE Analysis of heavy metals in industrial waste Inspection kit for CN, NH 3 in water

n n Multi component simultaneous pesticide analysis in domestic and imported food by GC-MS and LCMS Total hardness of natural drinking water related to taste of drinking water Analysis of potassium permanganate Measuring of mass concentration of ambient particulate matters (PM 10)

KOBE University ELISA practice and analysis technique n ELISA kit; Tube and Microplate types n ELISA analysis for pesticide (Alachlor) n

Useful Subject to solve the problem in Thailand Pesticide registration system n Analysis of environmental sample n Good Agricultural Practice n Good Laboratory Practice n Waste management n

Action Plan n n n Report to the Department of Agriculture Implement of GLP Propose for implementation and adaptation Review Training Propose for up-to-date instrument
