In Canada studies on the presence of trace organic contaminants (TrOCs) such as pharmaceuticals, personal care products, pesticides and flame retardants in lakes have primarily focused water column at localized scales. To address this gap, occurrence 44 TrOCs, representative various types human activities, was investigated surface sediments (0-2 cm) from 193 across Canada. A total 28 targeted TrOCs were detected, with 99.5 % samples containing least one detection, lake exhibiting up to 12 detections. The most frequently detected (> 20 samples) insect-repellent diethyltoluamide (DEET), UV filter oxybenzone, tris(2-butoxyethyl) phosphate (TBEP), tris(2-chloroethyl) (TCEP), triphenyl (TPP), stimulant caffeine, cotinine, a metabolite nicotine.

Glyphosate (GLY) is a well-known herbicide with significant applications in both agriculture and non-agriculture. However, GLY overuse recent years has resulted detection of residues many crops, endangering human health food safety. Our aim to investigate the relationship between urinary mortality, as well its influencing factors. The National Health Nutrition Examination Survey (NHANES) data from 4740 American adults were examined. Fitted smooth curves, generalized summation models, multiple logistic regression models used mortality. To potential regulatory elements two effects, perform subgroup analysis. During median follow-up 4.03 years, there total 238 all-cause deaths, 75 cardiovascular disease (CVD) deaths 52 cancer deaths. positively correlated Each 1 ng/ml increase was associated 40% increased risk mortality (Hazard ratio (HR) 1.40, 95% confidence interval (CI) 1.09-1.80), an 50% High group compared Low (HR 1.50, CI 1.05-2.14). In analysis, association significantly modified by gender (P for interaction = 0.03), hypertension 0.022). Higher seems be more death, may affect this association. Furthermore, urine have higher effect on people without hypertension.
