Pesticide and herbicide contamination refers to the presence and persistence of synthetic or natural plant protection chemicals and their transformation products in environmental compartments such as soil, surface water, groundwater, sediments, air, and biota. Research on this topic examines sources (agricultural runoff, spray drift, leaching, improper disposal), transport and fate processes (sorption–desorption, volatilization, photolysis, hydrolysis, biodegradation), and bioaccumulation and biomagnification in food webs. It also encompasses mixture toxicity, sublethal and chronic effects on non-target organisms, development of resistance, and the use of monitoring, risk assessment frameworks, and remediation or mitigation strategies to manage and reduce ecological and human health risks.
Researchers at Concordia have developed a new system using tiny nanosensors called carbon dots to detect the presence of the widely used chemical glyphosate. Their research, titled "Ratiometric Sensing of Glyphosate in Water ...
