Lifetime Cumulative Environmental Exposure Assessment

A scientifically validated tool that combines real-time environmental data from multiple global APIs with individual lifestyle factors to calculate cumulative exposure risks. All calculations are based on peer-reviewed epidemiological models.

Your Timeline

Lifestyle & Exposure Questionnaire

This questionnaire is based on validated epidemiological surveys (NHANES, EPIC, PLCO). Your answers help us personalize the risk assessment beyond environmental data.

Smoking & Tobacco (WHO 2021, IARC)

What is your smoking status?

NHANES

Never smoked (less than 100 cigarettes lifetime) Former smoker (quit at least 1 year ago) Current smoker (1-10 cigarettes/day) Current smoker (11-20 cigarettes/day) Current smoker (21+ cigarettes/day)

If you ever smoked, at what age did you start?

PLCO

If you quit smoking, how many years ago?

WHO

How often are you exposed to secondhand smoke?

Lancet 2019

Rarely or never Occasionally (less than 1 hour/week) Frequently (1-5 hours/week) Daily (more than 5 hours/week)

Occupational Exposures (ILO, NIOSH)

Have you worked in any of these industries for more than 1 year?

NIOSH

Construction, mining, or quarrying Manufacturing or heavy industry Agriculture, forestry, or fishing Healthcare or laboratory Transportation or logistics Chemical, painting, or printing Firefighting or emergency response

Total years in high-exposure occupations

OSHA

Workplace protective measures

EU-OSHA

Excellent (PPE always used, proper ventilation) Moderate (some protection, occasional exposure) Poor (no protection, frequent exposure)

Diet & Nutrition (EPIC, WHO)

Which dietary pattern best describes your lifetime habits?

Lancet 2019

Mediterranean (high vegetables, olive oil, fish) Western (high processed foods, red meat) Vegetarian or vegan Asian (rice, fish, vegetables) Mixed / varied diet

Daily fruit and vegetable consumption

WHO 2020

Less than 1 serving per day 1-2 servings per day 3-4 servings per day 5+ servings per day

Processed meat consumption

IARC

Less than once per week 1-3 times per week 4-6 times per week Daily or more

Physical Activity (ACSM, IPAQ)

Average lifetime physical activity level

IPAQ

Sedentary (little to no exercise) Light activity (walking, light chores) Moderate (exercise 2-3 times/week) Active (exercise 4-5 times/week) Very active (daily intense exercise)

Environmental Exposures (EEA, EPA)

Do you live near heavy traffic?

HEI

No (more than 1km from major roads) Yes, within 500m of moderate traffic Yes, within 100m of heavy traffic/highway

Proximity to industrial facilities

EEA

Never within 5km of industry Previously within 2km (moved away) Currently within 2km of industry

Medical & Family History (NIH, GBD)

Personal history of respiratory conditions

GINA

Doctor-diagnosed asthma COPD or chronic bronchitis Seasonal allergies or hay fever None of the above

Family history (first-degree relatives)

NCI

Lung cancer Breast cancer Heart disease before age 60 Stroke Type 2 diabetes None

Alcohol & Sleep (GBD 2019)

Average alcohol consumption

Lancet

Non-drinker or occasional (less than 1/month) Light (1-7 drinks/week) Moderate (8-14 drinks/week) Heavy (15+ drinks/week)

Average sleep duration

NIH

Less than 6 hours 6-8 hours More than 8 hours

Methodology

Weighted Cumulative Exposure Index (CEI):

Air Pollution: WHO log-linear model (RR = exp[0.0089 × (PM2.5 - 5)])
Smoking: Doll-Peto model with pack-years and secondhand smoke
Occupational: NIOSH job-exposure matrix with protection factors
Noise: WHO guidelines with OSM proximity analysis
Temperature: IPCC AR6 extreme event modeling
Diet/Activity: EPIC & GBD 2019 relative risk estimates

Data sources: Open-Meteo (ERA5 reanalysis), OpenWeatherMap, OpenStreetMap, REST Countries, World Bank, WHO, IARC, NIOSH.
