Human health risk assessment on the consumption of fruits and vegetables containing residual pesticides: A cancer and non-cancer risk/benefit perspective.

Pesticide residues in food is a public health concern. This study aimed to evaluate health risk and benefit associated with chronic consumption of fruits and vegetables (F&V) containing residual pesticides in the province of Quebec, Canada. Based on a representative sample of Quebecers (n=4727, aged 1-79) enrolled in the Canadian nutrition survey, population's mean chronic dietary exposure through consumption of F&V was evaluated for 169 different pesticide active ingredients (PAI), including 135 for which toxicological reference values (TRV) were available in the literature.

Relation between dietary acrylamide exposure and biomarkers of internal dose in Canadian teenagers.

Acrylamide (AA) is a probable human carcinogen found in several foods. Little information is available regarding exposure of adolescents, a subgroup potentially consuming more AA-rich foods. We investigated the relationship between dietary AA intake and levels of biomarkers of exposure (urinary metabolites and hemoglobin adducts) in 195 non-smoking teenagers of Montreal Island aged 10-17 years.

Dietary exposure to acrylamide in adolescents from a Canadian urban center.

The distribution of acrylamide in food items frequently consumed by Canadian adolescents was determined along with estimates of their contribution to the overall dietary intake of acrylamide. A total of 196 non-smoking adolescents (10-17 years old) were recruited in Montreal Island population, Canada. Participants were invited to fill out a 2-day food diary and a food frequency questionnaire over the last month.

Drinking water intake by infants living in rural Quebec (Canada).

Drinking water is a potential source of toxic contaminant and it is well known that water intake on a body weight basis decreases rapidly with increasing age. Nevertheless, few studies have been conducted on water intake of very young infants who might be particularly sensitive to some toxic chemicals. The objective of this study was to describe the mean and distribution of total water intake of 2-month old infants living in agricultural areas.
