Developing Global Leaders for Research, Regulation and Stewardship of Crop Protection Chemistry in the 21st Century
(ACS Publications, 2015-04-09)
To provide sufficient food and fiber to the increasing global population, the technologies associated with crop protection are growing ever more sophisticated but, at the same time, societal expectations for the safe use ...
BULK DEPOSITION OF PESTICIDES IN A CANADIAN CITY: PART 2. IMPACT OF MALATHION USE WITHIN CITY-LIMITS
(2015-03)
Malathion is an organophosphate insecticide registered for use in cities throughout North America to control adult mosquitoes. The objective of this study was to determine the impact of urban malathion applications on the ...
Phosphate and glyphosate sorption in soils following long-term phosphate applications
(2017-12-01)
Phosphate and glyphosate molecules compete for sorption sites in soil. The objective of this study was to quantify the impact of Olsen P concentrations in two contrasting soils on phosphate and glyphosate sorption. Soils ...
BULK DEPOSITION OF PESTICIDES IN A CANADIAN CITY: PART 1 GLYPHOSATE AND OTHER AGRICULTURAL PESTICIDES
(2015-03)
Winnipeg is a city in the Canadian Prairies with a population of about 600,000. Like many other cities and towns in this region of Canada, the city is surrounded by agriculture. Weekly bulk deposition samples were collected ...
17 β-Estradiol mineralization in human waste products and soil in the presence and the absence of antimicrobials
(Taylor Francis, 2016-06)
Natural steroidal estrogens such as 17 β-estradiol (E2), as well as antimicrobials such as doxycycline and norfloxacin, are excreted by humans and hence detected in sewage sludge and biosolid. The disposal of human waste ...
Phosphate fertilizer impacts on glyphosate sorption by soil
(Elsevier, 2016-05)
This research examined the impact of field-aged phosphate and cadmium (Cd) concentrations, and fresh phosphate co-applications, on glyphosate sorption by soil. Soil samples were collected in 2013 from research plots that ...
Sorption and desorption of glyphosate, MCPA and tetracycline and their mixtures in soil as influenced by phosphate
(2017-09-29)
Phosphate fertilizers and herbicides such as glyphosate and MCPA are commonly applied to agricultural land, and antibiotics such as tetracycline have been detected in soils following the application of livestock manures ...
Bacteria in drinking water sources of a First Nation reserve in Canada
(Elsevier, 2016-09-29)
Approximately 20% of the 600 First Nations reserves across Canada are under a drinking water advisory, often due to unacceptable levels of bacteria. In this study, we detected fecal bacteria at an alarmingly high frequency ...
Near-infrared spectroscopy as a tool for generating sorption input parameters for pesticide fate modeling
(2016-06-24)
Sorption parameters (such as Kd values) are among the most sensitive input parameters in pesticide fate models. This study demonstrates that near-infrared spectroscopy (NIRS), in combination with batch equilibrium techniques, ...
17β-Estradiol mineralization under field and laboratory incubations
(2017)
Mineralization studies of natural steroid hormones (e.g., 17β-estradiol, E2) are performed in environmental incubators, usually under a constant temperature such as 20°C. In this paper, we present a microcosm protocol that ...
