China Pesticide Risk Assessment

Pesticide risk assessment evaluates the chance and magnitude of harmful effects caused by pesticides to humans and ecological systems under specific use conditions by using scientific data and assessment models. Pesticide risk assessment report is an important part of pesticide registration data requirement, including a human health risk assessment report, an ecological risk assessment report and a dietary risk assessment report. The Data Requirements on Pesticide Registration, which came into effect in 2017, clearly specifies different risk assessment requirements for different product registration types (please refer to the annex of this article).

Human Health Risk Assessment

Depending on exposed human popultions, human health risk assessment can be divided into operator health risk assessment and resident health risk assessment. Operator health risk assessment is the process to determine if the use of a pesticide product poses unacceptable health risks to pesticide operators when they mix, load and apply pesticides. Resident risk assessment is the process to determine if the use of aerosol or repellent etc poses unacceptable health risks to residents.

Assessment Basis:

  • NY/T 3153-2017 Guidance on health risk assessment of pesticide operators;

  • Backpacker sprayer operator unit exposure - ICAMA;

  • NY/T 3154.1-2017 Guidance on health risk assessment of public health pesticides Part 1 - mosquito coil, vaporizing mat and liquid vaporizer;

  • NY/T 3154.2-2017Guidance on health risk assessment of public health pesticides Part 2 - aerosols;

  • NY/T 3154.3-2017 Guidance on health risk assessment of public health pesticides Part 3 -  repellent.

Environmental Risk Assessment

Pesticide environmental risk assessment refers to the use of science, technology and available information to assess the potential risks and adverse effects of pesticide use on the environment under specific conditions. At present, protection targets considered in enviromental risk assessment include aquatic ecosystem, birds, bees, silkworm, groundwater, non-target arthropods and soil organisms.

Assessment Basis:

  • NY/T 2882.1-2016 Guidance on environmental risk assessment for pesticide registration –Part 1: General principles

  • NY/T 2882.2-2016 Guidance on environmental risk assessment for pesticide registration –Part 2: Aquatic ecosystem

  • NY/T 2882.3-2016 Guidance on environmental risk assessment for pesticide registration –Part 3: Birds

  • NY/T 2882.4-2016 Guidance on environmental risk assessment for pesticide registration –Part 4: Honeybee

  • NY/T 2882.5-2016 Guidance on environmental risk assessment for pesticide registration –Part 5: Silkworm

  • NY/T 2882.6-2016 Guidance on environmental risk assessment for pesticide registration –Part 6: Groundwater

  • NY/T 2882.7-2016 Guidance on environmental risk assessment for pesticide registration –Part 7: Non-target arthropods

  • NY/T 2882.8-2017 Guidance on environmental risk assessment for pesticide registration –Part 8: Soil organism

Dietary Risk Assessment

Dietary risk assessment refers to the scientific assessment of the likelihood and extent of health risks arising from the dietary intake of pesticide residues according to the dietary structure of consumers by analyzing the toxicology data and residual study results of pesticides. It includes toxicology assessment, residual chemistry assessment, dietary intake assessment and risk characterization.

Assessment Basis:

  • Guidance on pesticide residue risk assessment

  • Guidance on setting pesticide acceptable daily intake

  • Guidance on setting pesticide acute reference dose

  • NY/T 3096-2017 Guideline for the testing of pesticide metabolism in crops

  • NY/T 3095-2017 Guideline for the processing test on pesticide residue in commodities

  • NY/T 3094-2017 Guideline for the Stability Testing of Pesticide Residue in Stored Commodities

  • NY/T 788 - Guideline on pesticide residue trials

Our Services and Advantages

The agrochemical division of CRIS group is located in Beijing. All team members have master's degree or above. The core members of this team are senior regulatory experts and risk assessment technical experts that have worked in top multinational agrochemical companies for many years. 

We can provide bilingual and high-quality health risk assessment reports, environmental risk assessment reports and dietary risk assessment reports, reducing the risks that a pesticide cannot be registered due to the problems of risk assessment reports in the process of pesticide registration. We can also provide high-tier risk assessment strategies when tier 1 risk assessment fails.
