Poisoning Regulation, Research, Health, and the Environment: The Glyphosate-Based Herbicides Case in Canada.

Despite discourse advocating pesticide reduction, there has been an exponential increase in pesticide use worldwide in the agricultural sector over the last 30 years. Glyphosate-Based Herbicides (GBHs) are the most widely used pesticides on the planet as well as in Canada, where a total of almost 470 million kilograms of declared "active" ingredient glyphosate was sold between 2007 and 2018. GBHs accounted for 58% of pesticides used in the agriculture sector in Canada in 2017.

Toxic effects of PCDD/Fs mixtures on Eisenia andrei earthworms.

The earthworms Eisenia andrei were used to study the toxicity of PCDD/Fs mixtures to earthworms during 28 day of exposure. The experiments were performed on artificial soils contaminated with dioxins at levels of C1 (0.1 ng 2, 3, 7, 8-TCDD/g soil), C2 (1 ng 2, 3, 7, 8-TCDD/g soil) and C3 (1.

Social context, the struggle with uncertainty, and subjective risk as meaning-rich constructs for explaining HBP noncompliance.

Objective: To identify the reasons for which people fail to take blood-pressure-lowering medication regularly, a qualitative study was conducted.

Methods: Interviews lasting approximately 90 min were conducted with 27 patients (15 women, 12 men) aged 40-70. The verbatim of the 27 interviews was first read and divided into segments with explanatory value.

Hair manganese and hyperactive behaviors: pilot study of school-age children exposed through tap water.

Background: Neurotoxic effects are known to occur with inhalation of manganese particulates, but very few data are available on exposure to Mn in water. We undertook a pilot study in a community in Quebec (Canada) where naturally occurring high Mn levels were present in the public water system. Our objective was to test the hypothesis that greater exposure to Mn via drinking water would be reflected in higher Mn content in hair which, in turn, would be associated with increased level of hyperactive behaviors.
