Risk Assessment and Monitoring for Environmental Chemicals

Prachathipat Pongpinyo


  • 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

  • Gain knowledge of Risk Assessment

  • Relates to my work

  • To know more analysis methods

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

  • Food Safety

    • Calculate by Acceptable Daily Intake value (ADI)

    • Study of toxicity of each substances

    • Pesticide safety evaluation committee

    • Endocrine Disruptor suspected pesticide

  • 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

  • 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

  • Eco-toxicological effect study

  • Environment fate study

  • Ecological risk assessment toxicity exposure ratio

  • Study of distribution, effect and fate of man-made organic substances

  • 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

  • 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


  • 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

  • Control the temperature to above 850C

  • Activated carbon

  • Active coke reactor

  • Dioxin catalyst

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

  • 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

  • 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


  • GC, GC-MS

  • LC, LC-MS

  • UV-Vis spectophotometer

  • Portable devices such as pH, DO, CO, CO2, conductivity

  • AAS

Hyogo Prefecture Technology Center on Agriculture, Forestry and Fisheries (HPTCAFF)

  • 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

  • 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)

  • 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, NH3 in water

  • Multi component simultaneous pesticide analysis in domestic and imported food by GC-MS and LC-MS

  • Total hardness of natural drinking water  related to taste of drinking water

  • Analysis of potassium permanganate

  • Measuring of mass concentration of ambient particulate matters (PM10)

KOBE University

  • ELISA practice and analysis technique

  • ELISA kit; Tube and Microplate types

  • ELISA analysis for pesticide (Alachlor)

Useful Subject to solve the problem in Thailand

  • Pesticide registration system

  • Analysis of environmental sample

  • Good Agricultural Practice

  • Good Laboratory Practice

  • Waste management

Action Plan

  • Report to the Department of Agriculture

  • Implement of GLP

  • Propose for implementation and adaptation

  • Review

  • Training

  • Propose for up-to-date instrument
