Dataset for human sensitivity to chemicals during development of motor function.

Area of Science:

• Environmental Health
• Toxicology
• Developmental Pediatrics

Background:

• Chemicals reviewed by the Agency for Toxic Substances and Disease Registry (ATSDR) pose potential risks.
• Motor development is a critical indicator of neurotoxicity.
• Understanding chemical impacts on human motor development is crucial for public health.

Purpose of the Study:

• To compile and analyze human data on motor development following exposure to specific chemicals.
• To assess the relevance of animal study findings to human populations.
• To identify critical exposure windows for developmental neurotoxicity.

Main Methods:

• Systematic review of human epidemiological and toxicological studies.
• Data extraction included chemical identity, exposure details (route, duration, frequency), study design, and cohort characteristics.
• Inclusion of No Observed Adverse Effect Level (NOAEL) and Lowest Observed Adverse Effect Level (LOAEL) where available.

Main Results:

• A dataset was created linking chemical exposures to observed motor development outcomes in human cohorts.
• Variables such as exposure route, duration, frequency, and subject sex were systematically recorded.
• Geographic location and study design were documented to contextualize findings.

Conclusions:

• The compiled human data can validate motor development outcomes from animal exposure studies.
• This resource aids in determining the human relevance of animal-derived neurodevelopmental toxicity data.
• Facilitates a better understanding of chemical impacts on human motor development across different exposure scenarios.
