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.
A decade after Connecticut implemented its 2010 ban on pesticide use on school grounds, a comprehensive three-part series, "Impacts of the 2010 Connecticut School Grounds Pesticide Ban a Decade Later," examines the long-term ...
