Groundwater Contamination

INTRODUCTION In the southern United States, chemicals are an integral part of the management of bare-root nurseries. The rationale for using chemicals is based on economics as they can reduce hand labor, improve the use of valuable seed, and increase seedling performance. The cost of all chemicals associated with loblolly pine seedling production averages less than 0.2 cent per seedling. The co...

Management of Contamination Risks and Identification of Contamination Sources

Abstract: Some aspects of management of contamination risks based on monitoring contamination sources are under consideration. The case when direct measurements are impossible and the values of the contamination inputs should be estimated through observations of indirect indicators is studied. Standard mathematical models describing the diffusion of a contaminant in the form of partial differen...

Contamination and Cross Contamination on Hospital Surfaces and Medical Equipment

T he role of medical devices, such as bronchoscopes, in the transmission of healthcare-associated infections (HAIs) has long been recognized, however, the evidence that environmental and medical equipment surfaces play a role in the transmission of HAIs has been weak. Studies have demonstrated that pathogens can be transmitted from surfaces to personnel and patients, and that these pathogens ar...
