slide2
Researh and development of material in agriculture such as soil, water and fertilizer
  • Analysis service
  • Consult and certified the other laboatories
  • Research and study in nuclear agrochemical
  • Cooperate with another institute
purpose for attending this course
Purpose for attending this course
  • Gain knowledge of Risk Assessment
  • Relates to my work
  • To know more analysis methods
what i have studied
What I have studied???
  • “Silent Spring” & “Our Stolen Future”
  • Endocrine Disrupting Chemicals
    • Naturally or Synthesis substances
    • Effect to human
    • Can change sex in some species
    • Concentrate through the food chain
slide5
Food Safety
    • Calculate by Acceptable Daily Intake value (ADI)
    • Study of toxicity of each substances
    • Pesticide safety evaluation committee
    • Endocrine Disruptor suspected pesticide
slide6
Maximum Residue Limit (MRLs)
    • Related to the ADI value
    • Set up for each pesticides
  • Good Agricultural Practice (GAP)
    • Decrease the effect of pesticide
    • Reduce the dosage volume
    • More effective control
  • Safety assessment of pesticide
  • How to conserve the environment…
dioxins pcbs cfc
Dioxins, PCBs, CFC
  • Remain in the environment for a long time
  • Accumulated in the body of living creature
  • Concentrate through the food chain
  • How to conserve and sustain the environment
registration of new pesticides
Registration of new pesticides
  • Eco-toxicological effect study
  • Environment fate study
  • Ecological risk assessment toxicity exposure ratio
  • Study of distribution, effect and fate of man-made organic substances
slide9
Bio accumulation in the environment
    • Accumulation of Organochlorines in river water and sea water
    • Accumulation of Organochlorines in stripped dolphin
    • Accumulation of Organochlorines in plankton in Osaka bay area
treatment of agro chemical compounds
Treatment of agro-chemical compounds
  • 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
Solid waste management

Incineration

  • Reduce mass
  • Deodorization
  • Detoxification

Exhaust treatment is require for eliminate particulate matter such as HCl, SO2, NO2, dioxins and heavy metals

alternative way to reduce dioxins
Alternative way to reduce dioxins
  • Control the temperature to above 850C
  • Activated carbon
  • Active coke reactor
  • Dioxin catalyst
consideration of waste management policy
Consideration of waste management policy
  • Current status of waste treatment/disposal
  • Responsibility of waste
  • Treatment and disposal technique for hazardous waste
  • Source of emission
metabolism of pesticide in plant study
Metabolism of pesticide in plant study
  • 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
Soil Study
  • Prediction half-life of pesticide
  • Clay type hold more pesticide than sandy soil
  • Leaching test; the herbicide was contained in mineral soil than volcanic ash soil
  • NO3 caused a meehemoglobinemia disease
practice observation
Practice/Observation
  • GC, GC-MS
  • LC, LC-MS
  • UV-Vis spectophotometer
  • Portable devices such as pH, DO, CO, CO2, conductivity
  • AAS
