[edit]Introduction:
[edit]- Update explanation of pesticide residue
- ways people come in contact with it.
- Why pesticide use is important and what are some of the concerns with coming to contact with its residues.
- Some of the common residues found
Pesticide residue by country
[edit]- Keep information on different regulations.
- Maximum Residue Levels (MRLs) set by the EU
- MRL in New Zealand
- MRL in UK
- MRL in the US
Assessment methods
[edit]- Difficulties with assessment
- Differences in periods and levels of exposure.
- Types of pesticides used
- environment pesticides are used in i.e weather, landscape
- Tissue residue approach
- used to infer mechanisms of toxic action
- Evaluate toxicity of mixtures
- limitiations
- The four step process for human health risk assessment used by the EPA
- Hazard Identification
- Dose-Response Assessment
- Exposure Assessment
- Risk Characterization
Pesticide residue and impact on health:
[edit]- Effects of pesticide depend on
- Txicity of the pesticide
- measures taken during application
- Dosage applied
- Weather conditions
- Duration of persistence in the environment
- transformation into other compounds
- Occupational Hazard
- close contact with concentrated pesticides
- methods of applying pesticide
- Contact through food and water
- Via leaching into soil
- spray drift
- Non-intentional chemical substances
- reaction of chlorine with organic compounds to form “unintended” chemicals
- organothiphsophate pesticides and increase of choline-esterase inhibitory activity.
- chlorophenols
- Polynuclear aromatic hydrocarbons
- Implications in cancer.
- Implications in neurological disease.
