Nanomaterials Regulation in Agrochemicals

 

Authorities

 

 

To safeguard human health and the environment, Environmental Protection Agency (EPA) collaborates with federal, state, territory, and tribal regulatory partners to administer and ensure compliance with the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). FIFRA allows the Environmental Protection Agency (EPA) to register pesticides. The mission of the Office of Enforcement and Compliance Assurance (OECA) under FIFRA is to ensure that the environmental and public health protections provided by our nation's environmental pesticide laws are realised through activities such as compliance monitoring, civil and administrative enforcement to address noncompliance, and criminal enforcement when necessary. The EPA establishes tolerances (maximum legally permitted levels) for pesticide residues in food under the Federal Food, Drug, and Cosmetic Act (FFDCA).

 

 

Overview

 

 

On the Environmental Protection Agency (EPA) official website, the pesticide is described as “any substance or mixture of substances intended for:

  • Preventing, destroying, repelling, or mitigating any pest.
  • Use as a plant regulator, defoliant, or desiccant.
  • Use as a nitrogen stabilizer”
  • Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)
  • The following are the main objectives of FIFRA compliance monitoring:
  • Prioritizing compliance monitoring activities;
  • Providing a visible field presence to encourage compliance and deter noncompliance;
  • Assessing and documenting compliance with FIFRA, the implementing regulations, pesticide labels, and pesticide registrations;
  • Identifying problem areas that require regulatory action by the Office of Pesticide Programs (OPP)

 

 

Compliance

 

 

One of the most important tools used by the EPA to guarantee that the regulated population follows environmental laws and regulations is compliance monitoring. It refers to all operations carried out by regulatory agencies to assess whether a facility (or a set of facilities, such as factories linked geographically, by sector, or by corporate structure) conforms with the law. The following are examples of compliance monitoring:

  • Compliance monitoring measures must be developed and implemented.
  • Compliance inspections, evaluations, and investigations are conducted on-site (including review of permits, data, and other documentation)
  • Data collection, evaluation, reporting, program coordination, oversight, and support inspector training, certification, and support off-site compliance monitoring
  • To encourage facilities to detect and report problems to the EPA, the agency offers compliance incentives and auditing.

 

 

EPA & Nanomaterials

 

 

More than 1,300 commercial goods contain manufactured nanoparticles, including medical equipment, textiles, fuel additives, cosmetics, polymers, and more. The most common nanomaterials that may have human and environmental health concerns are studied by EPA experts. The study is laying a scientific foundation for a better understanding, prediction, and management of nanomaterials' difficulties. Currently, EPA is studying nanosilver, zerovalent iron, titanium dioxide, cerium dioxide, carbon nanotubes, and micronized copper.

 

 

Test guidelines for nanomaterials

 

 

As per the data found on “new active ingredient registration status (2000-2021)” in the pesticide regulations, the following tests/studies were required before the ingredient could be reviewed-

Chemical- Silver chloride

  • Phase 1: Product characterization- Particle size distribution, surface area
  • Phase 2: Product testing- Stability, storage stability, corrosion characteristics, UV-Vis, solubility
  • Phase 3: Release characteristics/Exposure- Dissolution kinetics, leaching test of textile, dermal exposure indoors, inhalation exposure indoor, Attrition test- laundry drying
  • Phase 4: Health effects
  • Phase 5: Ecological effects
